How Mylar Bags Used In The Cannabis Industry Are Made
Mylar bags, also known as foil or metallized bags, are a popular packaging option in the cannabis industry, ideal for storing dried flowers and concentrates. Their strong barrier against light, air, and moisture helps maintain the product’s freshness and potency. Let’s explore how these essential bags are made and why they’re so effective.
Step 1: Producing the Polyester Film
The foundation of a Mylar bag is polyester film, made by polymerizing ester monomers. The resulting plastic is extruded into a thin sheet and stretched to increase durability and strength, making it ideal for packaging.
Step 2: Adding the Aluminum Coating
A thin layer of aluminum is added using vacuum metalizing. This process occurs in a vacuum chamber, where aluminum vapor is applied to the surface of the polyester film. This coating creates a light- and moisture-proof barrier that is essential for preserving cannabis products, as exposure to air and light can degrade potency and freshness.
Step 3: Cutting the Film
Once coated, the polyester film is cut into specific shapes and sizes according to bag design requirements. Customization at this stage allows manufacturers to create tailored solutions for different product needs.
Step 4: Heat Sealing for Airtight Protection
To form the final bag, high heat and pressure are used to seal the edges, creating an airtight enclosure. This airtight seal ensures the cannabis remains fresh and protected from environmental factors that could compromise quality.
Step 5: Custom Printing and Branding
The final step involves adding branding, labels, and product information using a process called flexographic printing. This technique transfers ink onto the bag, allowing manufacturers and dispensaries to customize the packaging to suit their needs and stand out in a competitive market.
