There are different vacuum packaging requirements for different food, including: cause of corruption (light, water or oxygen, etc.), shape of product, surface hardness of product, storage Conditions, sterilization temperature, etc.
I will introuduce the structure of vacuum bag (or vacuum film) for reference.
An application with a regular shape or a soft surface, like meat sausage products, soy products, etc.
· We suggest following structures:
Sterilization temperature <100 |
Sterilization temperature >100 |
OPA/PE |
OPA/CPP |
OPA/PE (high temperature resistant PE) |
· Take following reason into considering
☒ High puncture resistance
☑ Barrier properties
☑ Sterilization temperature
An application with hardness or sharp surface, like meat product with bone.
· We suggest following structures:
General product |
Product weight < 500g |
PET/PA/PE |
OPA/OPA/PE |
OPET/OPA/CPP |
· Take following reason into considering
☑ High puncture resistance
☑ Barrier properties
☑ Sterilization temperature
☑Cushioning
Deteriorating application, like low temperature meat products.· Take following reason into considering
☑ High puncture resistance
☑ Barrier properties
☑ Sterilization temperature
☑Cushioning
· We suggest following structures:
General product |
High sterilization temperature |

Coextruded film |
Dry composite film |
PVDC shrink bag |
Dry composite bag |
