Description
Cold stretch hood film, also known as the cold-drawn casing film, cold stretch sleeve film, the stretching cover or cold shrink film, is a tube-shaped elastic plastic with a hot seal at the top, which is stretched horizontally at room temperature, it is a new packaging technology that can replace heat shrinkable film and winding film by covering the top of the package vertically and releasing the elasticity at the bottom of the tray to wrap the product tightly. The film formulations provide significant economic benefits, excellent toughness, controlled clamping force and elasticity, and excellent transparency.
These cold stretch hood films have excellent clarity for use in branding, barcode scanning and quality control and other very important value chain links are efficiently utilized.
Wide range of applications:
• Large and small household appliances
• Bagged products (eg chemicals, sand, cement, soil and peat)
• Packaging materials and paper
• Construction products (eg bricks, tiles and insulation)
• Beverages, packaged foods and bottled goods
All-around protection & Significant economic benefits:
• It can realize five-sided and six-sided omni-directional protection, waterproof, antifouling and dustproof
• Good packaging integrity, speed up the turnover rate
• Long-term maintenance of good clamping force and flexibility, packaging security and stability
• Excellent toughness, puncture resistance and tear resistance
• Can achieve the reduction of packaging, reduce waste sources.
• Energy conservation and emission reduction, reduce energy consumption and industrial emissions.
