Custom Heat Seal Mylar Bags

Professional Foil Pouch Packaging for Your Products

Custom heat seal mylar bags are one of the most versatile and protective flexible packaging formats available for food, supplement, cannabis, cosmetic, and specialty consumer product brands. The multilayer foil structure of a mylar pouch creates an exceptional barrier against oxygen, moisture, light, and odors, preserving product freshness and potency significantly longer than standard plastic or paper packaging alone. Heat sealing creates an airtight, tamper-evident closure that consumers recognize as a signal of product quality and safety. Teal Packaging works with manufacturing partners to produce custom heat seal mylar bags with a minimum order of 50 units, free shipping to the US, Canada, UK, and Australia, and a two-week standard turnaround.

The range of products packaged in custom heat seal mylar bags is broad: premium coffee and tea, protein powders and nutritional supplements, cannabis and hemp flower, CBD extracts, freeze-dried foods, pet treats, dehydrated snacks, cosmetic powders, electronics components, and pharmaceutical raw materials. In each category, the mylar pouch format delivers a combination of barrier performance, print quality, and structural flexibility that rigid boxes cannot match for certain product types.

Teal Packaging's free design support team helps brands develop custom mylar bag specifications that match product requirements, branding standards, and retail channel expectations. From stand-up pouches with resealable zippers to flat seal pouches for single-serve applications, the team covers the full range of heat seal mylar configurations.

Materials and Specifications for Custom Mylar Bags

The term "mylar" refers to the biaxially oriented polyethylene terephthalate (BoPET) film layer in a multilayer flexible packaging structure. Custom heat seal mylar bags from Teal Packaging are produced from the following laminated film structures:

• PET/AL/PE (polyester, aluminum foil, polyethylene): The most common three-layer mylar structure. The aluminum foil layer provides an absolute barrier to oxygen, moisture, and light. Total laminate thickness typically ranges from 90-130 microns depending on application requirements. Ideal for food preservation, cannabis storage, and supplement packaging where maximum shelf life extension is the priority.
• PET/VMPET/PE (polyester, metallized polyester, polyethylene): A three-layer structure using a metallized polyester layer in place of solid aluminum foil. Provides excellent barrier performance with a lighter weight and a slightly more flexible hand feel. Suitable for snack foods, spices, and powders where a metallic-finish exterior is desired without the opacity of full foil.
• PET/PE (polyester, polyethylene): A two-layer structure for applications where moderate barrier performance is sufficient. Lower gauge weights make this option cost-effective for products with shorter shelf life requirements or products that are consumed quickly after opening.
• Matte finish laminates: Matte exterior surfaces provide a premium tactile quality and an excellent print surface for digital and flexographic printing. Available across all laminate structures above.

All material specifications can be produced with child-resistant zipper closures, resealable press-to-close seals, tear notches, and rounded or straight-corner configurations. FSC-certified paper exterior laminates are available for brands seeking a sustainable aesthetic alongside barrier performance. For related packaging needs, explore our soap packaging.

Sustainability in Mylar Bag Packaging

Teal Packaging acknowledges that multilayer flexible packaging presents end-of-life recycling challenges and actively supports brands in making informed choices. Where product shelf life requirements allow, reduced-layer laminate structures minimize total material use per unit. For brands targeting compostable or recyclable flexible packaging, Teal Packaging can specify certified compostable film structures that maintain adequate barrier performance for certain food and supplement applications.

For brands where the barrier performance of mylar is non-negotiable, offsetting the impact through FSC-certified secondary packaging and soy-ink printing on all printed surfaces is a practical approach. All ink and adhesive systems used in mylar bag printing and lamination are specified to minimize harmful chemical inputs throughout the supply chain.

For a complete sustainable e-commerce packaging program, pair your mylar bag products with custom mailer boxes for subscription-based product shipments, or explore custom subscription boxes for multi-product mylar bag bundle programs.
