Matching the gauge to your specific load ensures the optimal balance of strength, stretchability, and material efficiency.
Cast stretch wrap is made through a process where melted resin is extruded through a flat die and cooled on rollers, resulting in a smooth, clear film. It offers excellent transparency, making it ideal for scanning barcodes and identifying products. Cast wrap is also quieter during application and offers consistent stretchability. Blown stretch wrap, on the other hand, is created by inflating melted resin into a bubble, then cooling it. This process creates a tougher, more puncture-resistant film with superior cling. However, it’s less clear and noisier during application. Cast wrap is suited for standard, lighter applications, while blown wrap excels in heavy-duty scenarios where durability is key.
Blown film refers to a manufacturing process where resin is inflated into a bubble to create plastic sheets. These sheets can then be used for various purposes, including stretch film production. Stretch film, however, specifically refers to the plastic film used to wrap and secure loads. Blown stretch film is a subtype of stretch film made using the blown film process. While all blown films are not stretch films, all blown stretch films are made using this method. Blown films may also be used for other applications, such as agricultural film or food packaging, making them more versatile than stretch film.
Cling film and stretch film differ primarily in purpose and properties. Cling film, often used in food packaging, adheres easily to surfaces like bowls and trays without external force. It’s typically thinner and focuses on maintaining freshness and preventing contamination. Stretch film, on the other hand, is designed to secure pallets or loads. It requires tension during application and provides load stability during transportation. Stretch film is thicker and offers high tensile strength, while cling film prioritizes flexibility and a lighter seal. Though both are made from similar materials like polyethylene, they serve vastly different industries and needs.
Shrink wrap and stretch wrap are different in application and behavior. Shrink wrap shrinks tightly around items when heat is applied, forming a firm, tamper-proof seal. It’s ideal for individual product packaging or bundling small items. Stretch wrap, conversely, is applied by stretching it around a load to secure it in place. It relies on tension and doesn’t require heat. Shrink wrap offers a more rigid and sealed finish, while stretch wrap remains flexible and elastic. While shrink wrap suits retail and small product packaging, stretch wrap is essential for palletizing and bulk transportation.
Hand wrap is a type of stretch wrap designed for manual application, typically in smaller-scale operations or where machinery isn’t practical.
