This is an article from ytpacki

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.


  1. 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


  1. 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
This structure has excellent adaptability and a better vacuuming effect without changing the shape of the product.

OPET/OPA/CPP

· Take following reason into considering
☑ High puncture resistance
☑ Barrier properties
☑ Sterilization temperature
☑Cushioning


  1. 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
(PA/PE/EVOH/PA/PE)

Dry composite film
(PA/PE, material with K coating)

PVDC shrink bag

Dry composite bag

· Take following reason into considering
☒ High puncture resistance
☑ Barrier properties
☑ Sterilization temperature
