When customizing mask bags, many customers do not know what material to customize. When they come to consult, they just know that there is such material in the bag, but they do not know what kind of material it is and what it is made of. Take the aluminum foil bag, for example, we all know that the bag is called an aluminum foil bag, but the vast majority of people are not what an aluminum foil bag is, even what color it is also do not know, more do not know that although it is called aluminum foil bag, not only aluminum foil this material can make bags, Here is a brief introduction from Soonseal packaging, a professional flexible packaging manufacturer.
1: HDPE/High-density polyethylene/Low-pressure polyethylene/Low-pressure film
This is the most common material, which is the kind of shopping bag we often see in the supermarket. It is made of our HDPE bag. This material can be made into a bag separately, which is a relatively common and cheap material on the market-a PO bag. This kind of material is more brittle, harder, low expansion rate, knead the sound is more brittle.
2: LDPE/Low-density polyethylene/High-pressure polyethylene/High pressure film
Transparent texture, soft, good toughness, good transparency, feel more slippery, the thicker the harder the material, the greater the expansion rate. This material can also be made into individual bags, which is a relatively common and cheap material just like PO bags.
3: OPP/ Directional polypropylene
This material is the most brittle, the highest transparency of the material, tension is not enough, it can be said that there is no tension, single most prone to burst, and the printing is the easiest to decolor, it is not good printing, need to be printed and put for a period of time in cutting bags.
4: CPP/ Flow polypropylene/Terminal stretch polypropylene
This material has high transparency, higher hardness than PE film, more clear, and longer than the base film of composite materials. Often combined with other films in bags, is a good composite film.
5: PET/ Polyethylene terephthalate grease
The material transparency is also very good, strength and toughness are better than polystyrene and polyvinyl chloride, not easy to break, and smooth and shiny surface. It is also one of the common composite materials.
6: Aluminum foil /AL
Aluminum foil is a thin sheet of high purity aluminum after many times of calendering. It is an excellent heat conductor and a light shield. Good mechanical strength, lightweight, no thermal bonding, with a metallic luster, good shading, a strong reflection of light, not easy to be corroded, good barrier, moisture-proof and water-proof, strong air tightness, and has aroma retention. Metallic luster, gas barrier, and adhesion viscosity are not high, after composite processing is easy to appear the aluminum layer transfer phenomenon.
There are a lot of materials above are transparent materials, generally from the naked eye can not see what they are not the same, only through the understanding of the performance, in order to know what he is specifically applicable to.
