PVC food-specific film, all-round technical analysis

(Complies with food safety standards, suitable for refined warehouse management)

1. Core advantages

● Ultra-wide size

The widest domestic width is 4 meters (far exceeding the industry average of 2.5 meters), reducing splicing losses and improving sealing efficiency.

Supports customized heat sealing processing, which can seamlessly adapt to any size of grain piles/containers.

Ultimate protection performance

Anti-insect mechanism: physical barrier + surface antistatic coating (eliminating dust adsorption and destroying the environment for insect pests to attach).

Air tightness: oxygen permeability <5 cm³/m²·24h·atm (ASTM D3985 standard), inhibiting mold and oxidation.

Anti-aging: Add UV stabilizer, outdoor service life ≥5 years (70% tensile strength retention rate).

3. Application Scenario Expansion

● Grain Storage

Sealed tarpaulin for flat warehouses, vertical silos, and open-air grain stacks, which can be equipped with a circulating fumigation system.

Replaces traditional PE woven fabrics to solve the problem of easy invasion of pests at joints.

● Cross-industry applications

Food processing: moisture-proof and dust-proof covering for temporary storage areas of raw materials.

Cold chain logistics: anti-condensation packaging for pallet cargo.

Agriculture: sealing layer for forage silage and fruit and vegetable pre-cooling warehouse.
