PE heat shrink film

Introduction to PE heat shrink film

Core conclusion: PE heat shrink film is a thermoplastic film made from polyethylene (PE) through a special process. Its core function is to automatically shrink and tightly adhere to the surface of goods after heating, achieving fixation, protection, and beautification. Its core value is "strong adhesion+comprehensive protection+regular appearance", suitable for single or collective packaging scenarios of irregular/regular items. It is different from the "stretch fixation" of PE wrapping film and focuses more on "shrinkage adhesion".

Basic definition and core characteristics

PE heat shrink film is a thin film made of PE resin (with shrinkage promoter), which can be heated by hot air, infrared and other heating methods (temperature 80-150 ℃), with a horizontal/vertical shrinkage rate of up to 30% -80%, tightly wrapping the goods.

• Morphological features: supplied in roll (film roll) or pre made bag (shrink bag) form, width 10-200cm, thickness 10-50 μ m (0.01-0.05mm), single roll weight 1-20kg

• Core features: high shrinkage rate, transparent and bright, moisture-proof and dustproof, tamper proof, tear resistant, partially anti-static/anti fog

• Core difference: Compared with PE wrapping film, it does not rely on stretch rebound force, actively shrinks and adheres after heating, wraps more tightly, and has a more regular appearance, suitable for display packaging

• Applicable scenarios: Replace traditional packaging paper and plastic bags, suitable for shaping packaging of single products or collective packaging of multiple products
