What you don’t know about aluminum foil mask packaging bags

Before we start, let’s take a look at the mask bag.Aluminum foil bag packaging usually refers to aluminum-plastic composite vacuum packaging bags, which are suitable for moisture-proof, light-proof and vacuum packaging of large-scale precision machinery and equipment, chemical raw materials, and pharmaceutical intermediates. The four-layer structure is mostly used, which has good water and oxygen barrier functions. Unrestricted, packaging bags of different specifications and styles can be customized, and can be made into flat pockets, three-dimensional bags, organ bags and other styles. Product needs to beGBand ASTMStandard testing, the products meet the requirements of environmental protection (third-party testing reports can be provided), and the products meet the most stringent environmental protection standards for packaging materials in the European Union and North America.(1) Strong air barrier performance, anti-oxidation, waterproof and moisture-proof.(2) Strong mechanical properties, high blast resistance, puncture resistance and tear resistance.(3) high temperature resistance (121℃), low temperature resistance (-50℃), good oil resistance and fragrance retention.(4) non-toxic and tasteless, in line with food and drug packaging hygiene standards.(5) Good heat sealing performance, good flexibility and high barrier performance. twenty fourSilkFood grade aluminum foil bagIn order to reduce production costs and increase product profits, many cosmetic manufacturers will choose{Aluminized bag}.Aluminized bagIt is easy for many customers to distinguish between aluminum foil bags and aluminized bags. In order to let everyone understand, let me explain the difference between aluminum foil bags and aluminized bags.Aluminized bag (film) It is a high-purity metal aluminum uniformly coated on a plastic film under a high temperature vacuum state. Because it is coated on plastic, metal aluminum mainly plays a decorative role, and does not help greatly to improve the barrier property of the material.Aluminum foil bag (film) It is made of pure metal aluminum sheet, and the thinnest thickness can reach0.0065MM,If you stab it lightly with your hand, it will break.,Although it is so thin, it looks weak,But compound it with other plastics,It has a great effect.After compounding with more than one layer of plastic,improve the barrier properties of plastics,tightness,Fragrance retention,shielding,etc. function. 1, Watch: Because the brightness of aluminum foil is not as bright as that of aluminum plating, the reflectivity of aluminum foil is not as good as that of aluminized film. The appearance of aluminized matte film is very similar to that of aluminum foil. The mouth of the bag can be blocked, and the inside of the bag can be seen through strong light. The inside of the aluminum foil bag is opaque, and the light-transmitting bag is the aluminum-plated bag. 2, Hand feel: The hand feeling of the aluminum foil bag is thick and stiff, harder and heavier, and the hand feeling of the aluminized bag is lighter and softer than that of the aluminum foil bag. 3, Folding: Aluminum foil bags are easy to be folded to form dead folds and dead marks.
