If you’ve been shopping for food storage or custom packaging, you’ve probably come across Mylar bags, sleek, metallic pouches that seem to keep everything fresh for ages. But what are they, and why businesses and households relied on them so much?
This article will tell you how Mylar packaging, its uses, and what staysure Packaging helps brands turn the practical solution into a powerful marketing tool.
Understanding What a Mylar Bag Is
A mylar bag is a special type of package made from polyethylene terephthalate, which is biaxially oriented in polyethylene terephthalate. This material was first developed by DuPont in the 1950s and is used almost all over the globe because it is strong, flexible and excellent barrier properties.
DuPont’s trade name for this material comes from the name “Mylar.” Mylar bags have long become one of the most popular forms of food preservation, coffee storage, herbal products, and survival kits.
With Staysure Packaging, we manufacture quality Mylar bags that lock in freshness, block light and protect you from moisture. As you store your products, your products will still remain as perfect as they were packing.
How Do Mylar Bags Work?
The real magic of Mylar is the structure. A typical Mylar bag is made up of multiple layers, polyester, aluminum coating and polyethylene. This layer is made up of layers of protection against air, moisture, odor, and UV light.
You heat-seal a Mylar bag so it creates an airtight barrier that prevents oxygen from reaching the bag. That is why coffee beans, dried fruit and herbs remain fresh for months — or even years — without the smell or taste of the item.
To add a touch of perfection to the packaging, Staysure Packaging uses food-safe materials and cutting-edge sealing technology to ensure that each bag is strong, reliable and visually appealing.
What Are Mylar Bags Made Of?
- Here are some highlights of the layers that make Mylar bags so effective.
- BoPET: This outer layer of polyester film provides stability and flexibility.
- Aluminum Coating: It illuminates light and gives strong resistance to oxygen.
- Polyethylene Layer, used for sealing and food safety.
These three materials cooperate to form the tough, lightweight, and moisture resistant pouch. The result is a packaging that looks professional, works well under various conditions and is easily performable.
For those storage or selling items, We are proud to offer Mylar bags in multiple thicknesses at Staysure Packaging. Our solutions range from fine coffee, pet food or wellness products, and they fit your needs.
