Barrier Packaging That Preserves Product Quality

Oxygen, moisture, and light are the primary enemies of shelf-stable products. Oxygen causes oxidation — the chemical process that makes fats go rancid, colours fade, and flavours deteriorate. Moisture activates biological processes in dry products and causes physical degradation. UV light breaks down sensitive compounds in supplements and natural products. Mylar bags — technically polyester (PET) film with a metallised aluminium layer — block all three.

The barrier properties of mylar far exceed standard plastic bags, paper bags, or even most foil laminate alternatives. This is why mylar is the standard packaging material for food products designed for long shelf life, emergency preparedness supplies, premium supplements, and any product where maintaining the original quality from production to consumption is critical.

Mylar Bag Construction

Our custom mylar bags are manufactured from a multi-layer laminate:

• Outer PET layer: The print surface — provides structural stability and accepts high-quality CMYK print
• Aluminium foil layer: The barrier layer — provides near-total blockage of oxygen, moisture, and light transmission
• Inner PE or PP layer: The food-contact layer — heat-sealable, food-safe, creates the airtight seal

The combination creates Oxygen Transmission Rate (OTR) and Water Vapour Transmission Rate (WVTR) values many times better than standard flexible packaging materials.

Format Options

Flat Seal Bags

Three-side or four-side sealed bags for single-use or dispensed product. Simple, economical, and effective for product that will be consumed in one use. Common for individual supplement servings, single-use food portions, and sample packs.

Stand-Up Pouches with Zipper

Bottom-gusseted stand-up bags with resealable zip closure. The premium retail format — displays upright on shelves, reseals after first open, and provides full front-and-back print area. Our stand-up pouches page covers this format in full detail.

Flat Bottom Bags

Four-corner gusseted construction creates a flat bottom that stands independently — wider base than a standard stand-up pouch. Premium retail format used in premium coffee, tea, and supplement categories.

Industries and Applications

• Supplements and vitamins — moisture-sensitive powders and capsules
• Coffee and tea — preserves flavour and aroma by excluding oxygen
• Dried food and snacks — extends shelf life without preservative additives
• Cannabis and hemp products — odour containment and child-resistant options
• Cosmetics and skincare — powder and loose-formula products
• Emergency preparedness — long-term food storage at extreme shelf life

Frequently Asked Questions

What is the shelf life extension provided by mylar bags?

With an oxygen absorber included, mylar bags can extend shelf life to 10–25 years for appropriate dry products. For standard supplement and food retail applications (12–24 month shelf life), mylar provides substantial overkill in terms of barrier performance — the relevant benefit is quality preservation at retail timescales, not emergency storage.

Are custom mylar bags food-safe?

Yes. Our bags are manufactured with food-grade inner PE/PP layer meeting EU food contact material regulations and FDA 21 CFR requirements. We provide compliance documentation on request.

Can mylar bags include resealable zippers?

Yes. Press-to-close zipper seals are available on stand-up and flat-bottom formats. Child-resistant zipper options are available for regulated product categories.
