Packaging film ZDF04

for food packagingshrinkpolyolefin

Introduction
ZDF04 anti-fog cross-linked polyolefin shrink film is engineered for outer packaging of refrigerated products and industrial goods that require condensation control and high-clarity presentation. The film provides anti-fog performance, enhanced puncture resistance and excellent optical properties for retail display, transport and storage.

Thickness
Available gauges: 11 µm, 15 µm, 19 µm.

Features

• Anti-fog: Hydrophilic surface prevents droplet formation and preserves product visibility in cold or humid environments.
• Mechanical strength: Cross-linked structure delivers improved tear and puncture resistance during handling and distribution.
• High clarity: Low haze and high gloss ensure clear product presentation and reliable barcode/readability.
• Customizable: Width, length, thickness and color can be tailored to packaging specifications.
• Shrink performance: Uniform shrink on heat application for tight packs and protection against dust and contaminants.

Applications
Designed for refrigerated food (fruits, vegetables, prepared foods), pharmaceuticals, electronics, bundled or irregular-shaped items and any product requiring anti-fog protection and clear display.

FAQ (selected)

• What is anti-fog film? — A film treated to prevent fogging by promoting uniform moisture spread, commonly used in food and medical packaging.
• Does anti-fog film work? — Yes; performance depends on film type, storage conditions and application.
• How is anti-fog film made? — Typically via hydrophilic additives or coatings on the film surface; cross-linking improves mechanical properties.
• What is cross-linked shrink film? — A shrink film processed by cross-linking to increase tensile strength and puncture resistance for demanding packaging applications.
