shape. It affects food safety, shelf life, packaging cost, and even the way the bottle itself has to be designed. When you compare\u00a0<strong><b>hot fill vs cold fill<\/b><\/strong>\u00a0in glass bottles, you are not only picking a process. You are shaping how your product looks, tastes, and lasts on the shelf.<\/p>\n<p>Glass is used everywhere in beverages because it protects flavor, looks premium, and works with different filling systems. Still, the same bottle will not fit every process. That is why understanding\u00a0<strong><b>hot fill glass bottles<\/b><\/strong>\u00a0and <a href=\"https:\/\/smilebottles.com\/th\/product\/beverage-bottle\/\" target=\"_blank\" rel=\"noopener\"><strong><b>cold fill glass bottles<\/b><\/strong><\/a>\u00a0is worth your time before you place a large order.<\/p>\n<p>This guide walks you through both methods in plain language. You will see what each process really does, where each one fits best, and how to choose the right approach for your product. By the end, you should feel more confident when talking to your filling partner or your packaging supplier.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-2d68637 e-flex e-con-boxed e-con e-parent\" data-id=\"2d68637\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-c8b387e elementor-widget elementor-widget-text-editor\" data-id=\"c8b387e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2><span class=\"ez-toc-section\" id=\"What_Is_Hot_Filling_in_Glass_Bottles\"><\/span><strong><b>What Is Hot Filling in Glass Bottles?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><strong><b>What hot filling means<\/b><\/strong><\/h3>\n<p>So\u00a0what is hot filling? In simple terms, the product is heated to a high temperature first, then filled into clean or sterilized glass bottles while still hot. The bottle is sealed right after filling, and the heat inside helps reduce or destroy microorganisms.<\/p>\n<p>The idea is straightforward: the\u00a0hot fill\u00a0process uses the product\u2019s own heat to help preserve it. That is why it is common for beverages and sauces that need a longer shelf life at room temperature.<\/p>\n<h3><strong><b>Typical hot filling temperature range<\/b><\/strong><\/h3>\n<p>Fill temperatures usually sit around\u00a085\u00b0C to 95\u00b0C. Some products go a little higher or lower, depending on:\u00a0product type, acidity (pH), viscosity, regulatory requirements in the target market<\/p>\n<p>A thin fruit juice, a thicker tomato sauce, and a functional tea will not follow the exact same setting, but they often fall inside this range.<\/p>\n<h3><strong><b>Common products that use hot filling<\/b><\/strong><\/h3>\n<p>You will often see hot filling in:fruit juices, ready-to-drink teas, isotonic and sports drinks, tomato-based products, sauces, syrups, some functional beverages<\/p>\n<p>These are usually products that are either acidic or stable enough to handle heat without losing their identity.<\/p>\n<h3><strong><b>Why glass bottles work well for hot filling<\/b><\/strong><\/h3>\n<p>Glass has a few natural strengths that matter here. It can handle high temperature better than many plastics. It gives strong barrier protection, so your product stays cleaner for longer. It looks premium on the shelf, which supports brand positioning. It is recyclable. And it does not pass flavor into the product, which is important when you have spent time perfecting a recipe.<\/p>\n<p>For these reasons,\u00a0<a href=\"https:\/\/smilebottles.com\/th\/product\/\" target=\"_blank\" rel=\"noopener\"><strong><b>hot fill glass bottles<\/b><\/strong><\/a>\u00a0remain a common choice for juice, tea, and sauce brands around the world.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-4e18b69 e-flex e-con-boxed e-con e-parent\" data-id=\"4e18b69\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-c123dd0 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"c123dd0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"800\" height=\"437\" src=\"https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/What-Is-Hot-Filling-in-Glass-Bottles-1024x559.jpg\" class=\"attachment-large size-large wp-image-22582\" alt=\"\" srcset=\"https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/What-Is-Hot-Filling-in-Glass-Bottles-1024x559.jpg 1024w, https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/What-Is-Hot-Filling-in-Glass-Bottles-300x164.jpg 300w, https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/What-Is-Hot-Filling-in-Glass-Bottles-768x419.jpg 768w, https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/What-Is-Hot-Filling-in-Glass-Bottles.jpg 1100w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a49c8fd elementor-widget elementor-widget-text-editor\" data-id=\"a49c8fd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>What Is Hot Filling in Glass Bottles?<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-641e889 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"641e889\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><a href=\"https:\/\/smilebottles.com\/th\/contact\/\">REQUEST A QUOTE<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-1180560 e-flex e-con-boxed e-con e-parent\" data-id=\"1180560\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-89e303e elementor-widget elementor-widget-text-editor\" data-id=\"89e303e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2><span class=\"ez-toc-section\" id=\"What_Is_Cold_Filling_in_Glass_Bottles\"><\/span><strong><b>What Is Cold Filling in Glass Bottles?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><strong><b>What cold filling means<\/b><\/strong><\/h3>\n<p>If someone asks you\u00a0what is cold filling, the answer is basically the opposite. The product is filled at a low or ambient temperature. The heat step is either done separately or not needed at all.<\/p>\n<p>The\u00a0cold filled meaning\u00a0in everyday factory language is simple: the liquid never becomes the \u201csterilizing agent\u201d inside the bottle. Instead, the product and the container are cleaned and controlled through other methods, such as filtration, separate pasteurization, sterilization, refrigeration, or aseptic filling.<\/p>\n<h3><strong><b>Typical cold filling conditions<\/b><\/strong><\/h3>\n<p>Cold filling\u00a0may happen at chilled, cool, or room temperature. There is no single number that fits every line. What matters is that the safety of the product does not depend on hot temperature during filling. Instead, it depends on:line sanitation, sterilization, preservatives (when used), refrigeration, aseptic technology<\/p>\n<h3><strong><b>Common products that use cold filling<\/b><\/strong><\/h3>\n<p>Typical products include:\u00a0carbonated soft drinks, milk and other dairy beverages, beer, wine, spirits, probiotic drinks, some pharmaceutical and nutraceutical liquids, any product that reacts badly to heat<\/p>\n<p>Anything sensitive to temperature tends to end up on a cold fill line.<\/p>\n<h3><strong><b>Why manufacturers choose cold filling<\/b><\/strong><\/h3>\n<p>For many drinks, taste and quality can\u2019t survive high heat.

This heat step is a core part of microbial safety, so it has to hit the right temperature and hold long enough.<\/p>\n<h3><strong><b>Step 2: Glass bottle inspection and cleaning<\/b><\/strong><\/h3>\n<p>Before filling, bottles are checked for cracks, chips, or shape defects. They are then washed or air-rinsed, depending on the production standard. A tiny fault that is fine at room temperature can become a break point under heat, so this stage is more important than it looks.<\/p>\n<h3><strong><b>Step 3: Filling at high temperature<\/b><\/strong><\/h3>\n<p>Hot liquid goes into the glass bottle while the process temperature is kept stable. Sudden temperature drops can weaken the preservation effect, so the line is designed to keep heat steady.<\/p>\n<h3><strong><b>Step 4: Capping and sealing<\/b><\/strong><\/h3>\n<p>The bottle is sealed right after filling. Quick sealing keeps the headspace clean and helps lock in the effect of the heat. This is one reason closure compatibility matters so much for\u00a0hot fill\u00a0applications.<\/p>\n<h3><strong><b>Step 5: Inversion or holding period if required<\/b><\/strong><\/h3>\n<p>Some lines invert bottles for a short time after capping. That lets the hot product touch the cap and the headspace, which helps reduce contamination risk in that small but critical area.<\/p>\n<h3><strong><b>Step 6: Cooling<\/b><\/strong><\/h3>\n<p>After sealing, bottles cool gradually, usually through a cooling tunnel. Fast cooling can cause thermal shock and crack the glass. Slow, controlled cooling protects both the bottle and the product.<\/p>\n<h3><strong><b>Key control points in hot filling<\/b><\/strong><\/h3>\n<p>For your process, the main things to watch are:\u00a0fill temperature, holding time, closure compatibility, controlled cooling, glass bottle thermal resistance<\/p>\n<p>If any one of these is off, you may see broken bottles, deformed caps, or products that don\u2019t last as long as expected.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-7ad6f87 e-flex e-con-boxed e-con e-parent\" data-id=\"7ad6f87\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-be4aa21 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"be4aa21\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"437\" src=\"https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/cold-filling-glass-bevearge-bottles-1024x559.jpg\" class=\"attachment-large size-large wp-image-22584\" alt=\"\" srcset=\"https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/cold-filling-glass-bevearge-bottles-1024x559.jpg 1024w, https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/cold-filling-glass-bevearge-bottles-300x164.jpg 300w, https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/cold-filling-glass-bevearge-bottles-768x419.jpg 768w, https:\/\/smilebottles.com\/wp-content\/uploads\/2026\/09\/cold-filling-glass-bevearge-bottles.jpg 1100w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8477ecc elementor-widget elementor-widget-text-editor\" data-id=\"8477ecc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>glass beverage bottles<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-afb19c5 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"afb19c5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><a href=\"https:\/\/smilebottles.com\/th\/contact\/\">REQUEST A QUOTE<\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-92ba560 e-flex e-con-boxed e-con e-parent\" data-id=\"92ba560\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-ff486bc elementor-widget elementor-widget-text-editor\" data-id=\"ff486bc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2><span class=\"ez-toc-section\" id=\"How_the_Cold_Filling_Process_Works_in_Glass_Bottles\"><\/span><strong><b>How the Cold Filling Process Works in Glass Bottles<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The\u00a0cold filling process\u00a0looks simple on paper, but the control demands are different.<\/p>\n<h3><strong><b>Step 1: Product treatment and preparation<\/b><\/strong><\/h3>\n<p>Your product may be filtered, pasteurized separately, sterilized, or processed under aseptic conditions before it reaches the filler. The point is that the safety work is done before filling, not during it.<\/p>\n<h3><strong><b>Step 2: Bottle cleaning or sterilization<\/b><\/strong><\/h3>\n<p>Glass bottles are cleaned, and in many cases sterilized, before filling. For sensitive products, this step can decide whether the shelf life is stable or not.<\/p>\n<h3><strong><b>Step 3: Filling at low or ambient temperature<\/b><\/strong><\/h3>\n<p>The product enters the bottle under hygienic or aseptic conditions. Since there is no strong heat step at this moment, everything around the fill point has to stay very clean.<\/p>\n<h3><strong><b>Step 4: Capping and sealing<\/b><\/strong><\/h3>\n<p>Closures need to protect the product from contamination and, for carbonated or oxygen-sensitive drinks, from gas loss.

The real question is which one fits your product better<\/p>\n<h3><strong><b>Difference in temperature and processing<\/b><\/strong><\/h3>\n<p>The clearest gap is the fill temperature. Hot filling uses heat as a preservation tool. Cold filling relies on cleaner processing and other controls. This shapes almost every other decision after it.<\/p>\n<h3><strong><b>Difference in food safety control<\/b><\/strong><\/h3>\n<p>With hot filling, the heat itself does a lot of the safety work inside the bottle. With cold filling, safety comes from the environment: air quality, equipment sanitation, water quality, and closure integrity. Both can be safe, but the control focus is not the same.<\/p>\n<h3><strong><b>Difference in shelf life<\/b><\/strong><\/h3>\n<p>Well-designed hot-filled products can sit on ambient shelves for many months. Cold-filled products vary a lot. Some carbonated drinks and beers hold up well at room temperature, while dairy and probiotic drinks usually need refrigeration.<\/p>\n<h3><strong><b>Difference in product quality and taste<\/b><\/strong><\/h3>\n<p>Heat can be tough on delicate ingredients. Fresh notes, natural aromas, some vitamins, and live cultures don\u2019t enjoy high temperatures. If you care most about a fresh, close-to-original taste, cold filling has an edge.<\/p>\n<h3><strong><b>Difference in packaging and bottle requirements<\/b><\/strong><\/h3>\n<p>Hot filling asks for bottles with good thermal shock resistance and closures that stay tight during cooling. Cold filling asks for bottles that meet the right hygiene, pressure, and barrier levels. Carbonated drinks in particular need bottles that can hold internal pressure without failure.<\/p>\n<h3><strong><b>Difference in production cost and efficiency<\/b><\/strong><\/h3>\n<p>Hot filling burns more energy for heating and cooling. Cold filling can save on heat but may cost more on sterile lines, aseptic technology, or cold-chain logistics. The \u201ccheaper\u201d option really depends on your existing setup and the volume you plan to run.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div

It ties into your brand, your target market, and your logistics. Here is how to think it through.<\/p>\n<h3><strong><b>Consider your product formulation<\/b><\/strong><\/h3>\n<p>Ask yourself:<\/p>\n<p>How acidic is your product?<\/p>\n<p>How much sugar does it contain?<\/p>\n<p>Does it include dairy, cream, or protein?<\/p>\n<p>Is it carbonated?<\/p>\n<p>Are any ingredients sensitive to heat?<\/p>\n<p>A high-acid juice can usually handle hot filling. A dairy-based probiotic drink usually cannot.<\/p>\n<h3><strong><b>Consider your shelf-life target<\/b><\/strong><\/h3>\n<p>Do you need ambient shelf life for supermarket distribution, or is a chilled shelf life fine for your market? Are you exporting long distances? The longer and hotter the journey, the more shelf stability matters.<\/p>\n<h3><strong><b>Consider food safety and compliance<\/b><\/strong><\/h3>\n<p>Different markets have different rules. Check local regulations, microbial risk levels, and how much you want to rely on preservatives. Cold filling may push you toward stricter validation, while hot filling requires steady heat control.<\/p>\n<h3><strong><b>Consider bottle and closure design<\/b><\/strong><\/h3>\n<p>Whatever process you pick, your bottle has to match. Look at:\u00a0thermal shock resistance, neck finish compatibility, cap liner suitability, internal pressure requirements<\/p>\n<p>A great process with the wrong bottle will still fail. This is one of the most common issues buyers run into.<\/p>\n<h3><strong><b>Consider production cost and line capability<\/b><\/strong><\/h3>\n<p>Think about what you already have. Do you have heating and cooling equipment? Aseptic filling capacity? Cold-chain logistics? Adding a new capability from scratch is a big investment. Fitting the process to your current line often saves money and time.<\/p>\n<h3><strong><b>Consider consumer positioning<\/b><\/strong><\/h3>\n<p>If your brand is built on \u201cclean label,\u201d \u201cpreservative free,\u201d or \u201cfresh taste,\u201d that shapes the decision too. A premium probiotic drink almost always calls for cold filling. A shelf-stable, no-preservative juice may lean toward hot filling. The process should match the story you want on the label.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-b0198cd e-flex e-con-boxed e-con e-parent\" data-id=\"b0198cd\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4211a08 elementor-widget elementor-widget-text-editor\" data-id=\"4211a08\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2><span class=\"ez-toc-section\" id=\"Why_Choose_Smilebottles_for_Hot_Fill_and_Cold_Fill_Glass_Bottles\"><\/span><strong><b>Why Choose Smilebottles for Hot Fill and Cold Fill Glass Bottles?<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you are sourcing bottles for either process, working with a supplier that understands beverage filling makes life easier.

It depends on your product, shelf-life target, and the equipment you can run. For high-acid juices and sauces, hot filling is often a strong fit. For carbonated or heat-sensitive drinks, cold filling usually wins.<\/p>\n<h3><strong><b>Q2:<\/b><\/strong><strong><b>Can glass bottles be used for both hot filling and cold filling?<\/b><\/strong><\/h3>\n<p>A2:Yes. But the bottle design has to match. Hot-fill bottles need thermal shock resistance. Cold-fill bottles for carbonated products need proper pressure resistance.<\/p>\n<h3><strong><b>Q3:<\/b><\/strong><strong><b>What temperature is used in hot filling?<\/b><\/strong><\/h3>\n<p>A3:Most hot-fill processes run around 85\u00b0C to 95\u00b0C, depending on the product and local regulations.<\/p>\n<h3><strong><b>Q4:<\/b><\/strong><strong><b>Is cold filling safer for carbonated drinks?<\/b><\/strong><\/h3>\n<p>A4:In general, yes. Carbonation is very sensitive to heat, so cold filling is normally the better choice for sparkling drinks, beer, and similar products.<\/p>\n<h3><strong><b>Q5:<\/b><\/strong><strong><b>Do hot-filled glass bottles need preservatives?<\/b><\/strong><\/h3>\n<p>A5:Not always. Many hot-filled products rely mostly on heat treatment and sealing. Whether preservatives are needed depends on the formula, target shelf life, and local rules.<\/p>\n<h3><strong><b>Q6:<\/b><\/strong><strong><b>Which is more expensive, hot filling or cold filling?<\/b><\/strong><\/h3>\n<p>A6:There is no single answer. Hot filling adds heating and cooling costs. Cold filling can raise costs for sterile equipment, aseptic systems, or cold-chain logistics. Your current setup usually decides which is cheaper for you.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div data-particle_enable=\"false\" data-particle-mobile-disabled=\"false\" class=\"elementor-element elementor-element-6ec0b48 e-flex e-con-boxed e-con e-parent\" data-id=\"6ec0b48\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-eb11904 elementor-widget elementor-widget-text-editor\" data-id=\"eb11904\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong><b>Conclusion<\/b><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><a href=\"https:\/\/smilebottles.com\/th\/contact\/\" target=\"_blank\" rel=\"noopener\"><strong>Glass bottles<\/strong> <\/a>can perform well in both, as long as the bottle design fits the process.
