We have all seen items shrink wrapped at the store. Packaging for multiple items in one “contained” space for bulk shipping or selling.
Once these films are affixed to the product a drum tight seal is formed. This enables protection in travel and storage.
What is shrink film?
Shrink Film = a material 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 common uses of shrink wrap are for wrapping food, gift baskets, boxes, toys, books, soaps, etc. Below is a breakdown of the two most commonly used types of shrink wrap.
PVC Shrink Film = A type of shrink wrap used for a variety of applications. The PVC stands for Polyvinyl chloride. Polyvinyl chloride is the third most produced plastic in the world. PVC shrink wrap was the most commonly used shrink film, until replaced several years ago by polyolefin (POF) shrink wrap.
Polvolefin Shrink Film = A type of shrink wrap that has become the preferred choice for packaging products both edible and non-edible. Polyolefin Shrink wrap is preferred for a variety of reasons including: fewer odors when sealed, stronger seal, and more flexible storage. Polyolefin shrink films do not have any chlorine; therefore they do not produce hydrogen chloride gas. Polyolefin shrink wrap does not have any plasticizers, so temperature is not an issue. Polyolefin can be stored in a wide range of temperatures and does not harden and soften in different environments like PVC shrink film.
