Cold-stretch sleeve film, also known as cold-stretch wrapping film, and commonly referred to as cold film or shrink film, belongs to the polyethylene film category.
During the packaging process, cold film does not require a heat source; the film itself possesses exceptional stretching and shrinking capabilities. After being stretched and wrapped around the product by a sleeve wrapping machine, the cold film tightly wraps the product using its own shrinking properties, thereby completing the packaging process.
