PVDC High-Barrier Shrink Films
A Professional Packaging Solution for Fresh Meat
As global demands for food safety and extended shelf life increase, the performance of cold-chain packaging materials has become a key focus for food producers and retailers. Among various materials, PVDC (polyvinylidene chloride) stands out due to its superior barrier properties against both gases and moisture, making it an ideal solution for packaging perishable products such as fresh meat, poultry, and seafood.
Why Choose PVDC for Fresh Product Packaging?
Co-Extruded Structure and Manufacturing Process
Our PVDC high-barrier shrink bags are produced using advanced five-layer co-extrusion blown film technology with the following structure: PE / EVA / PVDC / EVA / PE
Key features include:
-
Optimized Layer Design
Inner and outer PE/EVA layers ensure sealing performance and flexibility; the central PVDC layer provides strong barrier functionality.
-
Customizable Dimensions
Available in widths ranging from 165 mm to 500 mm, with lengths tailored to customer requirements.
-
Sustainability Focus
We carefully balance PVDC content to ensure both functional performance and environmental responsibility, complying with global regulatory standards.
The Importance of Proper Storage Conditions
● Prevents Ice Crystal Formation: Temperatures below 0°C cause ice crystals that damage cell walls and degrade meat texture.
● Inhibits Bacterial Growth: The bacterial growth rate is significantly slower in this range. When combined with the barrier protection of PVDC shrink bags, this helps extend shelf life dramatically.
Shelf life expectations using PVDC shrink film packaging: Pork: Up to 45 days / Lamb: 60–90 days / Beef: 90–120 days
Quality Control: From Packaging to Shelf
● Initial Microbial Testing: Conduct tests for total colony counts and E. coli before packaging to ensure acceptable baseline levels.
● End-of-Shelf-Life Testing: Re-test the same parameters at the end of the storage period (e.g., day 120) to validate stability and safety.
Controlling the initial microbial load is crucial. When combined with the superior barrier properties of PVDC, this approach enables reliable long-term preservation.
