custom printed mylar bags

The purity of our common food custom printed mylar bags is more than 99.5%. Its main characteristics are:
1. Good mechanical performance, can meet the use requirements of automatic packaging machinery, but the softness is not enough, the tear strength is low, the folding part is easy to break, but easy to process, and can be combined with other plastic films;
2.Light weight, which is conducive to reducing transportation costs;
3.No thermal bonding, acid and alkali resistance, easy to curl;
4.Metallic luster, good shading performance, strong light reflection ability, and the reflectivity can reach more than 95%;
5.Good barrier, not easy to corrosion, moisture-proof and waterproof, strong air tightness;
6.At high and low temperature, the shape is stable and not easy to expand and deform.
Material of custom printed mylar bags: PET / NY / Al / PE (general packaging); PET / NY / Al / CPP (high temperature cooking).
Ordinary_ The layer is polyester, which is used for puncture resistance_ The layer is aluminum foil, which functions as moisture-proof, conductive and shielding. The third layer is polyethylene, which functions as, Sealing, vacuum packaging, etc. The custom printed mylar bags made of this material usually has uniform and stable performance, the outer polyester can usually prevent collision, the conductive metal layer of the middle layer can quickly transfer heat dissipation, and the inner layer can keep the custom printed mylar bags from temperature change and stable shape.
Composite custom printed mylar bags are used for food packaging, generally used for packaging meat products, dried fish, aquatic products, cured meat, roast duck, roast chicken, roast pig, quick-frozen food, ham, cured meat products, sausage, cooked meat products, pickles, bean paste, seasoning, etc., with good aroma, quality, taste and color preservation effects.
