What materials can be used for food packaging:

Food packaging bags generally use PET film, PE film, PA film, OPP film and CPP film.

Their respective characteristics:

PET film: This film is super transparent, hard material, high temperature resistant, and good printing effect. It is more suitable for food packaging bags. The PET film feels particularly crisp to the touch, and it can make a rustling sound when held in the hand.

PE film: transparency is slightly inferior to cpp, but softer than cpp, PE film has better tensile properties and better tensile strength. There are two types of milky white PE and transparent PE (HDPE/LDPE/LLDPE), with a soft hand feeling.

PA film (nylon): PA material is relatively tough, has good transparency, abrasion resistance, puncture resistance, easy to be oxidized, easy to shrink and wrinkle, this material is suitable for packing similar bone products.

OPP film: The material is hard and cannot be stretched. The heat-sealing type is very good, but the transparency is relatively general, the material is brittle, and the hand feel is poor.

CPP film: CPP material has worse transparency than OPP but better than PE. The material is soft and resistant to high temperatures. It can be used as a printing material, but it is not easy to print.

Common food packaging bags are generally made of the above combination of materials:

1. Material: BOPP/LLDPE two-layer composite

Characteristics: moisture-proof, cold-resistant, low-temperature heat-sealing strength

Uses: instant noodles, snacks, frozen desserts, powdered packaging, etc.

2. Material: BOPP/CPP two-layer composite

Features: moisture-proof, oil-resistant, high transparency, good stiffness

Use: instant noodles, biscuits, candies, all kinds of light foods

3. Material: BOPP/VMCPP composite

Features: moisture-proof, oil-resistant, oxygen-proof, shading, good stiffness

composite bag

Use: all kinds of dry food, fried food, potato chips

4, material: BOPP/VMPET/LLDPE three-layer composite

Features: moisture-proof, oxygen-proof, shading

Use: all kinds of food, rice snacks, snacks, tea

5. Material: PET/CPP two-layer composite

Characteristics: moisture-proof, oxygen-proof, fragrance preservation, high temperature resistance

Usage: cooking, alcoholic food, flavored food

6. Material: PET/PET/CPP three-layer composite

Characteristics: moisture resistance, high temperature resistance, easy sealing

Use: powder packaging, soy sauce, liquid, shampoo
