Mylar food storage bags are a form of multi-layer foil that can be used to protect food from oxygen, moisture, and light. The shelf life of these bags ranges between a few months and several years depending on thickness and sealing. Our food-grade Mylar pouches are available in bulk quantities and include free UK delivery.
Mylar bags are flexible pouches made from laminated films, typically of aluminium foil, metallised polyester (MET-PET), and PET plastic. These films create an airtight barrier that stops the three major causes of food spoilage: oxygen, moisture, and light. The non-porous nature of the polymer also prevents the transfer of smells to and from food, keeping strong smelling products like coffee contained and protecting mildly flavoured foods from the smells in their surroundings. When correctly heat sealed, Mylar bags can store dry goods for 5–25 years, making them the choice for food storage and survival kits.
Mylar pouches are used in almost every dry or semi-dry food category.
Coffee and loose-leaf tea, where the barrier holds aroma and prevents oils from turning rancid. Pantry staples such as rice, flour, sugar, and lentils, which are free of moisture and pests. Snacks and nuts, which remain crunchy and flavourful much longer in plastic bags. Food storage for emergency and long-term storage, which many preppers prefer for its five-year shelf life. Pet food and treats, protected from humidity and insects. Protein powders and supplements that are sensitive to air and moisture.
Because a single pouch type is used across multiple industries, many businesses use Mylar on packaging across all of their products rather than using different materials for each item.
Thickening bags in mils differ depending on what is being stored and how long it needs to last. A 3.5 mil bag is good for snacks, tea, and coffee where freshness is always important. A 5 mil bag is good for everyday pantry items that require a bit more durability when handled and transported. A 7 mil bag is a heavy-duty bag designed for bulk grains, industrial packaging, and long-term emergency food storage where the pouch may be sealed tightly for years. We can also make custom sizes for products with special needs.
Mylar bags are available in small sample jugs or bulk bags for small scale manufacturing. Our range covers 30g and 50g pouches for product testing, giveaways, 1lb and 1kg bags for retail size products, 1-gallon and 2-gallon pouches for household or small bulk storage, and 5-gallon or 25kg sacks for wholesale and industrial use. We can supply a business from a prototype order to full-scale bulk.
Mylar pouches can be fully custom printed with logos, brand colours, and packaging text in full colour on digital or litho, matte or glossy finishes, spot UV, and metallic accents. The pouches come in many different styles, from stand-up bags, flat pouches, gusseted bags, zip-lock bags, heat-sealable bags, spouted pouches, and window pouches that let product see through. For private label sellers, this means that the packaging becomes part of the brand experience, and not just a container.
Prices vary depending on bag size, thickness, complexity of print and the number of orders. The per-unit cost drops dramatically when ordering larger quantities. The Printed Packaging UK offers very low minimum order quantities, so that small and new businesses can order a manageable quantity to test the packaging before committing to large orders. Free design support is available for those that don’t have prints yet.
The Printed Packaging UK specialises in offering wholesale Mylar food storage bags. Each bag is made of food-safe, multi-layer barrier film and can be sized, printed, and printed to match the product it is protecting. Our clients can request a free quote and design consultation before placing an order, quickly moving from concept to shelf-ready packaging. Read more: Custom 3.5 Mylar Bags
