Product Overview
The vacuum shrink bag is a food-contact grade, high-barrier flexible packaging bag specially engineered for fresh and processed proteins, including beef and lamb cuts, fatty beef bricks, cheese blocks, tuna and cured deli meats.
It shrinks tightly around the product under heat, eliminating loose wrinkles and purge while the co-extruded barrier structure blocks oxygen and moisture to keep contents fresh and appetizing.
Available in transparent and printed versions, it delivers a clean, premium retail appearance for vacuum display cases.
Material Structure
The bag is built from multi-layer co-extruded functional films. The outer layer provides mechanical strength, high gloss and puncture resistance during handling and transport. The middle barrier layer, based on EVOH or PA, is the key to blocking oxygen, moisture and odors, protecting color and flavor even in long-term chilled or frozen storage. The inner heat-seal layer is food-contact safe PE, ensuring strong vacuum seals and safe direct contact with food. All resins comply with food-contact regulations and the bag is BPA-free.
