Shrink Film – a cloth made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. There are a variety of uses for Shrink wrap and shrink film. Some typical applications of shrink wrap are for wrapping food, gift baskets, boxes, toys, books, soaps, etc. Beneath is a breakdown of the two most commonly used types of shrink.
PVC Shrink Film – A type of shrink wrap used for quite a lot of applications. The PVC stands for Polyvinyl chloride. Polyvinyl chloride is the third most-produced plastic within the world. PVC shrink wrap was the most commonly used shrink film until changed several years ago by polyolefin (POF) shrink wrap.
Common Uses of PVC Shrink Film – PVC shrink wrap uses include packaging boxes, CD and DVD packaging, software, small canisters, and other non-edible items.
Drawbacks of PVC Shrink Film – Sealing Strength, storage issues, and sealing by-products are common drawbacks of PVC Shrink Wrap. The plasticizer in PVC Shrink wrap hardens in cold conditions and softens under scorching conditions, due to this fact compromising the power of the seal and the plastic. PVC shrink wrap also releases small quantities of hydrogen chloride into the air and carbon deposits onto the sealer. Proper air flow is required when sealing PVC shrink wrap.
Polyolefin Shrink Film – A type of shrink wrap that has grow to be the desirered alternative for packaging products, each edible and non-edible. Polyolefin Shrink wrap is choosered for a variety of reasons, including fewer odors when sealed, stronger seal, and more flexible storage. Polyolefin shrink films should not have any chlorine; due to this fact, they don’t produce hydrogen chloride gas. Polyolefin shrink wrap does not have any plasticizers, so the temperature will not be an issue. Polyolefin will be stored in a wide range of temperatures and does not harden and soften in different environments like PVC shrink film.
Common Makes use of of Polyolefin Shrink Film – Polyolefin shrink film is used for almost every kind of application. Applications embrace toys, sporting goods, printed wrap, foods, stationery, and cards, just to name a few.
Drawbacks of Polyolefin Shrink Film – Value and machine compatibility are the two significant drawbacks of Polyolefin shrink film. Polyolefin is commonly more costly than PVC shrink wrap. Many packagers want PVC because of this reason. There are types of polyolefin shrink wrap which are more appropriate with machines, but Polyolefin machine compatibility has been a difficulty of packagers.
Cross-Linked Polyolefin Shrink Film – Irradiation is utilized to straightforward polyolefin shrink film to make the film stronger, and capable of better seal strength. Cross-linked shrink film is sterile, and FDA approved for direct food contact. It presents glorious clarity to display packaged products. To view in detail about making and the history of cross-linked shrink film view, our blog post titled What’s cross-linked shrink film.
Cross-linked shrink film also leaves less residue on sealers, promoting longer sealing blade or wire life. Cross-linked shrink film is made to be used with high-velocity machines and high output operations.
Widespread Uses of Cross-Linked Polyolefin Shrink Film – Cross-linked shrink film is used with the identical products as commonplace polyolefin shrink film. The cross-linked film is often used in high output operations. It can be used for heavier products; a conventional polyolefin shrink film can’t appropriately package.
Drawbacks of Cross-Linked Polyolefin Shrink Film – Cross-linked shrink film requires higher seal and shrink temps than an ordinary polyolefin shrink film. Higher temps can damage and deform products sensitive to heat. Higher seal and shrink temps. additionally, require higher energy costs.
