Cold stretch sleeve film, also known as stretch cover or shrink wrap, is a packaging technology that uses a tubular elastic plastic film with a heat seal at the top. After horizontal transverse stretching, it is vertically covered over the product at room temperature and releases its elasticity at the bottom of the tray to achieve a tight packaging effect on the product. This technology does not require heating and relies on the elasticity of the film itself to achieve a tight packaging effect, so it is also called stretch hood film.
Features
Environmental protection and energy saving: The cold stretch sleeve film does not need to be heated during the packaging process, which reduces energy consumption and industrial waste gas emissions. At the same time, it uses recyclable materials and meets environmental protection requirements.
Easy operation: The operation process is simple. Just put the film on the object, and the equipment can automatically complete the stretching and packaging, which greatly reduces the labor cost.
High efficiency: It can achieve continuous operation and significantly improve the packaging speed and efficiency.
All-round protection: It has good waterproof, anti-fouling and dust-proof properties, and can maintain the stability of the clamping force at a low temperature of -20℃, ensuring the integrity of the packaging and the safety of the product.
High transparency: The film has high transparency, which is easy to read barcodes and identify brands.
Application field
Stretch hood films are used in a wide range of industries, including:
Home appliance industry: used to protect home appliances while showing the beauty and features of the products, and the barcode can be scanned smoothly through the film.
Chemical industry: used for packaging of chemical products to avoid the influence of heat generated during heat shrinkage on chemicals.
Beverage industry: Suitable for packaging of various bottled beverages to ensure the stability and performance of the packaging.
Building materials industry: used for packaging of building products such as bricks, panels, cement, etc. to meet the needs of large differences in shapes and sizes.
