Heat shrink film is a type of packaging that can be firmly and tightly attached to a product. It can be made from different materials, such as polyolefin, PVC, and PE shrink film. Shrink film is available in different packaging forms, and the common ones are centerfold, single-wound, and shrink tube.<\/p>\n\n\n\n
If you have a 20-inch roll of centerfold shrink film, the actual width is 40 inches when you lay it flat.<\/p>\n\n\n\n
Centerfold shrink wrap comes in a wide variety of sizes, mainly width and thickness, as well as overall length. You can choose from two materials for folded shrink wrap: polyolefin shrink film and PVC shrink film. Folded shrink film is folded longitudinally from the center of the film to form a \u201cV\u201d shape, which, when folded together, becomes an \u201cI\u201d shape. The product can be inserted directly into the package, and the shrinking can be easily accomplished.<\/p>\n\n\n\n
Shrink and seal method:<\/strong><\/p>\n\n\n\n To shrink and seal the folded shrink film, an L-shaped sealer and a bundling machine must be used together. For the L-shaped sealer, please choose a model with a longer diameter, as you may one day use a wider width of shrink rolls.<\/p>\n\n\n\n Single-wound wrap is a shrink film made of one layer of film wrapped in a single flat layer. Generally speaking, single-wound wrap is more suitable for hand molding and sealing. Single-wound shrink film is also more suitable for sealing with a tell-tale shrink machine and is more suitable for tell-tale work than folded shrink film rolls.<\/p>\n\n\n\n Shrink and Seal Methods:<\/strong><\/p>\n\n\n\n A single-wound wrap can be shrunk using a high-speed shrink machine or a heat gun.<\/p>\n\n\n\n A shrink tube is a type of shrink film that is available in various sizes and looks like a \u201cround tube.\u201d It is continuous and can be used to wrap long cylindrical products. Shrink tubes are cut to the desired length of the product (note: allow for longer lengths before cutting).<\/p>\n\n\n\n Shrink tubes are generally used to package bottled beverages and food products. They protect the product from tampering and ensure that the customer receives an untampered product.<\/p>\n\n\n\n Shrink and Seal the way:<\/strong><\/p>\n\n\n\n Shrink tubing generally only needs to be sealed on one side; the other side is not typically sealed.<\/p>\n\n\nSingle wound shrink film<\/h3>\n\n\n\n
