제품 정보
Heat-seal foil and Mylar pouches
Custom printed aluminum foil mylar bags wholesale orders start with a heat-seal pouch that blocks light, oxygen and moisture, printed with your logo and sized to your fill weight.
Foil and Mylar pouches are laminated structures, usually PET printed film, aluminum foil or a metallized layer, and a PE sealant layer. The sealant layer fuses under heat and pressure, so the barrier runs to the top of the bag. We print, laminate and make the bags in our own cleanroom plant in Shenzhen.
Digital print starts at 1,000 pcs per design. Gravure starts at 10,000 pcs per design. Zipper, degassing valve, window, hang hole and tear notch are available. You get an itemized quote within one business day.

Barrier structure
How Foil and Mylar Pouches Block Light, Oxygen and Moisture
The barrier comes from the laminate layers, and the heat seal carries it to the bag mouth.
Aluminum foil is a continuous metal layer. Light, oxygen and water vapor pass through it at very low rates, which is why foil laminate is the usual choice for long freshness. Mylar bags use metallized PET, where a thin aluminum coating on the film blocks light and slows oxygen and moisture. The coating is thinner than foil, so barrier performance is usually lower.
Printed outer film protects the ink and gives the bag its look. A PE inner layer is the food-contact side and the heat-seal layer. Seal bars melt it into a continuous seam on the sides, bottom and top after filling.
A pouch is only as tight as its weakest seam, so seal width, temperature and dwell time matter as much as the film. Shelf life depends on your product, the fill weight, the structure and storage conditions. We do not quote a fixed number of days. We confirm the recommended structure in your quote.
Foil gives the highest barrier. Metallized film is a lighter-barrier option for shorter shelf-life products.
Foil, Mylar or Metallized Film: Choosing a Barrier for Your Product and Fill Weight
Choose by how sensitive the product is to oxygen, light and moisture, and by how long it must stay on shelf.
Roasted coffee, protein and supplement powders, and oily nuts oxidize and absorb moisture, so foil or high-barrier laminate is the usual starting point. Dry snacks and candy with shorter shelf-life targets can often use a metallized Mylar structure at lower cost. Larger fill weights give a lower surface-to-product ratio, which can relax the barrier requirement.
Fresh coffee needs a one-way degassing valve on a flat bottom or stand-up pouch. Light-sensitive products should not get a clear window, because it lets light in. If two structures fit your product, we recommend one in writing and price both, so you compare them on one quote.
Usually a good fit
- Foil laminate for oxygen- and light-sensitive products
- Metallized Mylar for shorter shelf-life dry goods
Usually not advised
- Clear window on light-sensitive products
- Valve-less bags for freshly roasted coffee
