Machine Stretch Film, also known as Stretch Wrap or Pallet stretch wrap, is a type of packaging material commonly used in industrial settings for securing and protecting palletized goods during storage and transportation. It is called "machine" Stretch Film because it is primarily used with stretch wrapping machines that automate the wrapping process.
Machine stretch film is made from linear low-density polyethylene (LLDPE) resin, which is a durable and stretchable plastic material. It is manufactured using a process called cast extrusion, where the molten resin is extruded through a flat die onto a chilled roller, forming a thin, continuous film. The key characteristic of machine stretch film is its ability to stretch significantly without tearing. This stretchability allows the film to conform tightly around pallets and their contents, creating a secure and stable load. The film is typically applied in multiple layers to enhance its strength and load stability. Machine stretch film offers several benefits: 1.Load Stability: It provides excellent load containment, preventing products on a pallet from shifting, falling, or becoming damaged during handling and transportation. 2.Protection: It acts as a protective barrier against moisture, dust, dirt, and other contaminants, keeping the goods clean and intact. 3.Tamper-Evidence: Machine stretch film can serve as a visual deterrent against tampering, as any unauthorized access or tampering would be immediately noticeable. 4.Cost-Effective: It is a cost-effective packaging solution compared to alternatives such as Strapping or shrink wrapping. 5.Efficiency: The use of stretch wrapping machines enables faster and more efficient packaging operations, reducing labor requirements and improving productivity. 6.Machine stretch film is available in various widths, thicknesses, and strengths to accommodate different load sizes and weights. It can also come in different formulations, such as pre-stretched film or high-performance films with added features like puncture resistance or UV protection, depending on specific application requirements.
Overall, Pallet Stretch Film plays a vital role in ensuring safe and secure palletized shipments, providing stability, protection, and efficiency in the logistics and supply chain industry.
