What Are Mylar Bags?

Mylar bags are made from BoPET (biaxially-oriented polyethylene terephthalate), a polyester film known for its excellent barrier properties and tensile strength. These bags are typically layered with aluminum foil and other protective materials to enhance their resistance to light, moisture, oxygen, and contaminants.

Available in a wide range of sizes and styles, Mylar bags are used for packaging everything from freeze-dried foods and electronics to cannabis products and emergency supplies.

Key Benefits of Mylar Bags

Superior Barrier Protection

One of the standout features of custom mylar bags canada is their ability to block moisture, air, and light — the three primary enemies of freshness. This makes them ideal for preserving the flavor, aroma, and shelf life of food products, herbs, and supplements. Mylar’s high-barrier properties also make it suitable for storing sensitive or perishable items for months or even years.

 Extended Shelf Life

Whether you're storing coffee beans, spices, grains, or emergency meals, Mylar bags significantly extend the shelf life of contents when paired with oxygen absorbers. These bags create an airtight seal that prevents spoilage and degradation over time, making them essential for preppers, food storage businesses, and long-term planners.

Durability and Puncture Resistance

Unlike thin plastic bags, Mylar bags are built to last. The polyester-aluminum layering makes them highly resistant to tears, punctures, and rough handling. This toughness ensures that your stored contents remain safe during shipping, storage, or outdoor activities like camping and hiking.

Lightweight and Flexible

Despite their durability, Mylar bags are lightweight and space-saving. Their flexible design allows them to be easily stored in tight spaces or packed flat until filled. This makes them a great choice for both personal use and large-scale commercial packaging.

Customizable and Heat-Sealable

Mylar bags can be customized with various features such as zip locks, tear notches, gussets, and hang holes. They can also be heat-sealed to provide a tamper-proof and airtight closure. Businesses can print custom logos and designs on Mylar packaging, giving their products a professional look while maintaining product integrity.
