Common Materials for Packaging Bags

1.Aluminum foil material
Commonly used in milk bags, frozen food bags, this material has strong air barrier properties, high temperature resistance (121 ° C), low temperature resistance (-50 ° C), oil resistance. But more fragile, easy to break, plus poor acid resistance, no heat sealability. So it is usually only used as the middle layer material of the bag
2.PET material
Commonly used in all kinds of food, medicine, non-toxic and non-sterile packaging materials. The transparency of this material is very good, strong sense of luster, strength and toughness is also better than other materials, but also not easy to break, and non-toxic, tasteless, safety
high, can be directly used for food packaging. But not heat-resistant, alkali resistance, can not be placed in hot water immersion.
3. Nylon material
Commonly used in meat products and boiled food. The transparency of the material is also very good, and heat-resistant, oil-resistant, puncture-resistant, and soft to the touch.
It is also softer to touch. However, it is not resistant to moisture, as well as poor heat sealability
4.0PP material
The use is very wide, clothing, food, printing, cosmetics, paper and other industries are used.
The material is the highest transparency of the bag material material. It is also the most brittle of the bag material materials, and the tensile force is also very small.
5.HDPE material
Commonly used in food packaging, grocery shopping bags. Can do both frozen food packaging, but also can be applied to 100 degrees Celsius boiling resistance
Processed bags. But easy to crack.
6.PVC plastic bags
Commonly used in food bags, stationery bags, cosmetic bags, transportation packaging, plastic shopping bags, garbage bags.
Has good water resistance and transparency, can be adjusted through the plasticizer measurement to change the tensile strength and tear strength, has a good processing. But the heat resistance is poor
