Cold stretch sleeving film, also known as cold shrink film, is a plastic film used for packaging and protection. Unlike heat shrink film, which requires heat to shrink onto an object, cold stretch sleeving film utilizes the elasticity of the material to provide a tight fit without the need for heat.
The following are some of the key features and considerations associated with cold stretch sleeving film:.
Material: Films are typically made from materials such as polyvinyl chloride (PVC), polyolefins (e.g., polyethylene or polypropylene) or blends of these polymers. These materials are chosen for their elasticity and ability to stretch and then shrink to a smaller size.
Elasticity: Cold drawn sleeving films are highly elastic, which allows them to be stretched over an object and then shrink tightly around it. This characteristic is important in providing a tight fit.
Thickness: The thickness of the film can vary depending on the application. Thicker films offer more durability and protection, but are less pliable and more difficult to package.
Color: The film can have masterbatch added to provide UV protection for some sensitive products.
Printing: Printing can be done on cold-stretch casing film.
APPLICATIONS: Cold Stretch Sleeving Film is commonly used for wrapping and bundling cables, wires, pipes and other items that require a tight protective layer.
Wrapping: The wrapping process stretches the film over the object and shrinks it back to its original size for a tight fit. This can be done manually or with specialized equipment.
Environmental Considerations: Partially biodegradable and recycled materials can be used.
Cost: The cost of cold stretch casing film depends on the material used, thickness.
Regulations: Some jurisdictions may have specific regulations regarding the materials used for packaging, including their environmental impact and recyclability.
Cold stretch sleeving film offers a convenient and effective way to wrap and protect a variety of items without the need for heat. Its flexibility and ease of use make it a popular choice for many industries and applications.
Blowing is typically accomplished using a three-layer co-extrusion blown film machine equipped with special cold stretch film dies.
