When it comes to cannabis packaging, finding the right Mylar bag sizes can be tricky. You need to know several factors about your product, from its content quantity to its type to your storage conditions. Our guide ensures you understand everything you need to know about these different-sized bags.

What are Mylar Bags?

Mylar bags are flexible packaging types made from a polyester film called PET (Polyethylene Terephthalate.) It is then stretched in two directions to create BoPET (Biaxially Oriented Polyethylene Terephthalate). This material is known for its outstanding properties, including:

• Chemical stability
• Gas and moisture barrier capabilities
• High tensile strength

Custom Mylar bags are widely used to preserve the freshness and integrity of various products, thanks to their exceptional ability to block external elements that could compromise quality. Their durability makes them a popular choice in the cannabis industry.

Why Use a Mylar Bag?

The primary purpose of a Mylar bag is to offer a durable and protective packaging solution. It safeguards the contents from external factors that could affect their freshness, integrity, or longevity.

Furthermore, Mylar bags provide you with:

• Brand identity and customization
• Contaminant protection and light-blocking
• Extended product lifespan
• Flavor and aroma preservation
• Long-term storage and transport
• Portion management
• Superior barrier properties

Custom Size Mylar Bags

Mylar bags can be customized to meet specific size requirements for unique items or applications. Choosing the right size ensures the contents fit properly without excess space, which could lead to spoilage or insufficient protection.

When selecting a size, it’s important to consider the following factors:

• Content quantity
• Product type
• Storage conditions

Furthermore, eco-friendly and customizable options enhance the versatility and appeal of Mylar bags. Choosing the right size based on the specific needs and characteristics of the contents ensures optimal protection and presentation.

Best Thickness for Mylar Bags

You’ll want to choose the appropriate thickness of your Mylar bags based on the package dimensions and storage duration. Thicker bags are recommended for long-term storage as they provide greater durability.
