also known as stretch wrap or stretch wrap film, is a highly stretchable plastic film commonly used for packaging and securing items together. It is made from linear low-density polyethylene (LLDPE) resin, which provides excellent stretchability, strength, and clarity. Stretch film is available in various thicknesses, widths, and lengths to suit different packaging needs. Here are some specifications related to quality, performance, and applications of stretch film:
Quality: Thickness: Stretch film is available in a range of thicknesses, typically measured in micrometers (μm).Thicker films generally offer higher puncture resistance and load-holding strength.
Clarity: Stretch film can have varying levels of clarity, ranging from transparent to opaque. Clear films allow for easy visibility of packaged items, while opaque films provide privacy or concealment.
Performance: Stretchability: Stretch film is designed to stretch and conform tightly around items, providing a secure and protective wrap. The stretchability of the film allows it to elongate without tearing, ensuring optimal load stability.
Puncture resistance: The ability of stretch film to resist punctures or tears is crucial for protecting packaged items and maintaining the integrity of the wrap during handling and transportation.
Tear resistance: Stretch films with high tear resistance can withstand rough handling and prevent tears or breaks from propagating across the film.
UV resistance: Some stretch films are formulated with UV inhibitors to protect packaged items from the harmful effects of ultraviolet (UV) radiation. This is especially important for outdoor storage or transportation.
Applications: Pallet wrapping: Stretch film is widely used for wrapping palletized loads to secure them during transit and prevent shifting or collapsing. It provides stability, protection against dust and moisture, and facilitates easy identification of goods.
Bundling: Stretch film is commonly employed to bundle smaller items together, such as boxes, cartons, or loose products. It keeps items tightly bound, preventing them from separating or shifting.
Storage and protection: Stretch film helps protect items from dirt, dust, and moisture during storage. It can be used to wrap furniture, appliances, or other large items to prevent scratches, abrasions, or damage.
