Shrink Film for Packaging
Polyolefin is a type of plastic packaging material commonly used for shrink wrap, and is available in a wide range of strengths, thicknesses, clarities and shrink ratios. Characteristics include:
- Shrink force: The measurement of pressure exerted onto the product being wrapped with polyolefin shrink film. High shrink force creates a tight, clean package, and works well for durable products. Fragile items, however, may become damaged due to the high pressure involved.
- Tear strength: Refers to what degree a puncture or tear will propagate across the polyolefin film. Film with high tear strength is ideal for products with irregular shapes, as well as sharp edges and corners, and is also appropriate for products that undergo rough shipping and handling processes.
- Tensile strength: This is the amount of force required to break the film when it is stretched. High tensile strength is more machinable, while low tensile film often has superior puncture resistance and flexibility.
- Stiffness: Measures the film’s rigidity. Stiff films are ideal for high speed wrapping equipment and operations, while softer films better conform to the product’s shape.
The film’s versatility make it ideal for a variety of applications, from packaged consumer goods on the retail shelf to industrial packaging, storage and shipping needs. Polyolefin shrink film is used to package products such as CDs, DVDs, books, magazines, medical and pharmaceutical products, consumer goods, processed foods, toys and games, electronics, and more.
