Mylar Bags

Mylar bags are one of the most effective packaging formats for cannabis flower, edibles, and concentrates. Their multi-layer construction blocks moisture, oxygen, light, and odor — making them a reliable choice for brands that need strong barrier protection without the bulk of a rigid container. This guide covers what to look for when buying mylar bags in bulk.

Material

Mylar bags are made from multiple layers of film that work together to block out the elements that degrade cannabis over time. The barrier construction keeps moisture and oxygen out, blocks light, and contains odor effectively.

The heat-seal closure creates an airtight finish that preserves freshness from the time the bag is sealed to the time it's opened. For brands that package product in advance or ship over long distances, that barrier performance is what keeps the product in good condition on arrival.

Size & Capacity

Mylar bags are available in a wide range of sizes — from small 1-gram pouches to large bags that hold a pound or more. The right size depends on your product quantity and how you're selling it. Single-serve portions need a smaller bag; bulk flower or multi-pack products need a larger format.

Choosing the right size matters for presentation as well as function. A bag that's too large for the product inside looks sloppy on the shelf. A bag that's too small is hard to seal properly and may not close flat. Match the bag size to your typical product weight before ordering in bulk.

Packaging Purpose

Dispensaries use mylar bags for flower, edibles, and concentrate packaging across a range of portion sizes. Cannabis brands use them for branded retail products where the flat, printable surface makes a strong visual impression on the shelf. Processors use them for bulk packaging and distribution where barrier protection is the priority.

Mylar bags are also a popular choice for brands that want a flexible, lightweight packaging format that's easy to ship and store compared to rigid containers.

Compliance & Child Resistance

Child-resistant zipper mylar bags are available and meet compliance requirements in most regulated cannabis markets. The CR zipper requires a specific motion to open, limiting access for young children while remaining functional for adults.

Always confirm your state's specific packaging requirements before ordering. Some markets require child-resistant packaging for all cannabis products at retail, while others have different rules depending on the product type or quantity.

Customization Options

Mylar bags offer one of the largest printable surfaces of any cannabis packaging format. Full custom printing with your logo, brand colors, strain information, and compliance text is available. The flat surface prints cleanly and makes a strong visual impression at retail.

For smaller runs or brands managing multiple SKUs, pre-designed bags with label application are a flexible option. For larger volumes, custom printed bags give a more finished, branded look that holds up well through handling and shipping.

Wholesale Buying Tips

Mylar bags are a high-volume item for most cannabis operations. Buying in bulk keeps your per-unit cost down and ensures consistent supply. PackTHC offers tiered wholesale pricing — the more you order, the lower the unit price.

Custom printed bags have longer lead times than stock options, so plan ahead if you're launching a new product or rebranding. Confirm MOQs before committing to a custom order — minimum quantities for custom printing are typically higher than for stock bags.
