Testing mylar bags or quality assurance is vital to meet the requirements of packaging that ensure the protection of products, build the brand reputation, and help them deliver their products in actual taste and quality to customers. Before packing the products in custom mylar bags, you should first test their raw materials whether they have excellent resistance to light, air, and moisture. After the successful testing of your pouches, you can confidently pack and deliver your food items to customers in actual quality and can increase your brand credibility.
In this article, as a packaging expert, I will guide you through a step-by-step guide on testing mylar packaging bags.
Materials and Tools Used for Testing
Mylar bags are made with various materials and designs in various locking styles. Thus, before the production of mylar bags, the quality assurance engineers test the raw materials with various equipment, such as an impulse sealer or vacuum sealer, flat irons, UV flashlight, moisture analyzer, handheld moisture meters, and RH sensors.
Air, Light, And Moisture Resistance Tests On Mylar Bags
Light Resistant Test
For a light resistant test you take the raw materials, such as a polythene sheet that you want to use for the customization of mylar bags.
Method: Place your mylar PET paper on the surface and put UV light on it. As every light color has various properties and it behaves differently with the substance. Thus, you should change the color of the light to check the final results.
Observation: Check that the light either passes through the mylar sheet or not. Thus, you need to carefully inspect the mylar bag or raw materials to get the final results.
Verdict: If the light will not pass through your BoPET (biaxially-oriented polyethylene terephthalate), then your custom mylar pouch bags for storage are ideal to protect food items from the UV rays. If the light passes through the PET materials, then you need to improve the quality of your raw materials before the customization of Mylar packaging bags.
Air Resistance Test
Air-tight mylar bags are essential for those products that need complete protection from air to maintain their actual quality. To start the air resistance test of custom edible mylar bags, you should take some essential tools, such as a heat sealer, a vacuum pump, or electronic pressure decay air testers.
Method 1: Take your Mylar bags and melt their edges using a heat sealer. After that, use a vacuum pump to remove the air from your Mylar bags, then seal the remaining edges again with the heat sealer.
Method 2: Besides this, you can test your air-filled Mylar packaging professionally using electronic pressure decay air testers. In this process, the machine presses the Mylar bag to check if there is any air leakage.
Manual Method: In this method, take the sealed Mylar bag in your hand and press it gently to check if any air is being released from anywhere. For this, you have to press the bags gently.
Observation: Carefully check whether the pressure of your customized mylar bags has decreased or is being maintained.
Verdict: If the air does not leak from your custom made mylar bags, then the bags are an excellent yet airtight storage option for those items that need complete protection from exposure to air. With the help of these bags, you can preserve the taste and freshness of your food items for a long time.
Moisture Resistance Test for Mylar Bags
Maintaining the quality of products requires protecting them from moisture. Therefore, I will tell you here about the moisture-resistant test for Mylar bags and how it is done.
Method: You can use various moisture sensing tools to check the moisture resistance quality of your polythene Mylar bags. Use Handheld Moisture Meters that will sense the moisture amount with various electrodes within a few seconds. You can also use the Relative Humidity (RH) Sensors/Hygrometers to measure the amount of moisture on the surface of your bags made with mylar materials.
Observations: Notice whether the moisture is present inside the Mylar bag packaging or not.
Final Results: If you do not notice any amount of moisture inside the mylar bags, then it’s clear that you can use these bags to pack those items that require protection from moisture.
Know Is Mylar Bag is Best to Meet The Packaging Needs of Your Products or Not
If your Mylar bags pass all types of tests, it means these bags are sufficiently effective in protecting food items from all kinds of contaminants. In packaging manufacturing companies like Silver Edge Packaging, they have their own quality assurance teams. This team ensures that the Mylar bags or packaging delivered to clients guarantee the protection of their products.
With the help of these QA tests, you can assure that the bags meet the safety standards for food to keep them safe from exposure to bacteria, moisture, oxygen, light, and air. With the help of these bags, you can preserve the taste and freshness of your desired food items and extend their shelf life. These tests also confirm that the personalized mylar bags are BPA-free, FDA-approved. If you want to learn, what are mylar bags? size chart, features, and use cases, read our blogs.
Conclusion
The testing of Mylar bags is very necessary to check whether these bags, which are used for packing food items, meet the safety standards or not. But yes, make sure that you have properly conducted the air resistance, moisture, and light tests. If your mylar packaging passes the test, then use it for product storage; otherwise, improve the quality of your mylar pouches. The FDA-approved custom mylar bags are essential to extend the shelf life of edibles, and you can get these bags from Silver Edge Packaging at affordable rates and with free shipping.
