Custom Printed Mylar Bags

Description

How Does Multi-layer Aluminum Laminate Extend Product Shelf Life and Prevent Degradation?

Mylar’s aluminum layer blocks light, oxygen, and moisture-the three elements that cause oxidation, mold growth, and nutrient loss. Coffee beans lose flavor compounds within days in standard plastic, but maintain aroma for 8-12 months in mylar. Vitamins degrade 40-60% faster when exposed to oxygen; mylar’s barrier keeps potency stable.

Cannabis loses THC potency through oxidation; proper mylar storage preserves strength for 12-18 months. The science works through laminate layers: outer PET (printable surface), middle aluminum (barrier), inner polyethylene (heat-sealable). This structure creates an impermeable shield tested at <0.02cc oxygen transmission per 24 hours—industry-leading protection. 

Do Cannabis and Hemp Mylar Bags Need Different Labeling in Every State?

Yes. Unlike federal nutrition labeling, cannabis and hemp exit-bag requirements are set state by state, and a bag compliant in Colorado is not automatically compliant in Michigan or Illinois. Most legal states require a universal cannabis symbol at a minimum printed size, a government health warning in a minimum font size, and child-resistant certification language printed directly on the bag rather than on a separate sticker. A bag missing any one element gets rejected at the dispensary’s own intake inspection, not just at a regulatory audit. We build state-specific label zones into the same structural dieline, swapping only the compliance panel per state.

Delivering a New Outlook of Packaging

High-speed automated fill lines running in co-packing facilities across Ohio and Tennessee process 60 to 120 mylar bags per minute, and at that speed, friction between film layers generates static charge that can attract dust into an open bag seconds before sealing. Some products, particularly dried herb and powder formats, also require a nitrogen flush at the moment of fill to displace oxygen before the seal closes, which only works if the bag’s inner layer holds the flush gas without ballooning the seal. We specify film stiffness and seal width tolerances that hold steady at fill-line speed, not just in static lab testing.

Material Options That Protect and Perform

We manufacture Mylar bags using premium films and laminates tested for strength, freshness retention, and recyclability. Choose from:

• Standard Mylar Film offering a strong oxygen and moisture barrier, suitable for snacks, teas, or dry foods.
• Metalised Mylar for light-sensitive products such as coffee beans, supplements, or cosmetics.
• Recyclable and Compostable Films that help meet your brand’s sustainability goals.
• High-Gloss or Matte Laminates for brands seeking visual distinction and premium presentation.

Finishes and Closures That Define Functionality

Every product has different needs. Our finishes and functional options ensure both aesthetics and practicality:

• Zip Locks and Tear Notches for resealable convenience and extended shelf life.
• Hang Holes or Euro Slots for retail display.
• Matte, Gloss, or Soft-Touch Surface Coating for the right tactile appeal.
• Foil Stamping or Spot UV to emphasize logos and design highlights.

Resealability determines whether customers use your product over weeks or waste it after opening. Zip-lock closures (press-to-seal mechanisms) maintain the barrier after initial opening, preventing oxygen re-entry that causes staleness. Tested closures survive 50+ open/close cycles without seal degradation. Tear notches positioned 1/4 inch from the top edge enable easy opening without scissors, preventing customer frustration that damages brand perception.

For retail display, hang holes (3/8 inch diameter) fit standard pegboard hooks, while euro slots accommodate retail clip strips. Matte finishes reduce glare under store lighting, making product details readable. Foil stamping highlights logos without additional costs beyond $75-150 plate fees.

Size selection affects both product fit and customer perception. Small bags (3×5, 4×6 inch) suit sample packs, single-serving snacks, or CBD gummies-portable formats customers carry easily. Medium bags (6×9, 8×10 inch) handle coffee (8-12 oz), protein powder servings, or dried herb quantities for weekly use. Large bags (10×14, 12×18 inch) accommodate bulk storage: 2-5 lb quantities, multi-month supplement supplies, or wholesale distribution. Proper sizing minimizes excess air (which accelerates oxidation) while preventing over-stuffing that stresses seals. Our standard thickness is 3.5 mil for lightweight products, 5 mil for sharp-edged items (coffee beans, supplements with capsules). 

Designed For Your Unique Brand Perspective

The polyethylene inner layer is the only surface that touches your product directly, and it must pass FDA 21 CFR Part 177 migration testing before it can hold food, supplements, or anything else consumed. Migration testing confirms the laminate does not transfer plasticizers or adhesive residue into the product, even after weeks of direct contact.

Brands sourcing mylar film from unverified suppliers in markets outside the US sometimes receive laminate that was never migration-tested for their specific product category. We verify and document FDA compliance for every laminate run, so the certification exists before a single bag reaches your warehouse.

Filling Every Bag with Sustainability

A bag that holds the right volume of product can still fail on a co-packer’s fill line if its dimensions do not match the machine’s tooling. Co-packing facilities operating in Texas and North Carolina run specific bag widths, gusset depths, and seal-area dimensions calibrated to their filling equipment, and a half-millimeter mismatch at the seal area can cause jams or incomplete seals at production speed.

Before finalizing a dieline for co-packed products, we request the target facility’s machine specifications and build the bag to match those tolerances exactly, not just to a generic standard size. This single step prevents the most common cause of co-packing rejection.

Contact Today to Place Your Order!

A single-SKU retail brand selling one product nationally needs one compliant label design and a bag that performs identically whether it ships to a customer in Oregon or Virginia.

A multi-state cannabis or hemp operator distributing through co-packers in different legal states needs the same structural bag with a different compliance panel for every state, filled on different machines with different tooling tolerances.

We engineer one base dieline that flexes both ways: a single label for national retail, or a state-specific panel set and machine-matched dimensions for multi-state co-packing. Call 1-844-259-7225 or email sales@alypackaging.com to scope your run.
