A shrink wrapper machine is a packaging system designed to wrap products in a plastic film that shrinks tightly around them when heat is applied. It typically includes a sealing unit and a heat tunnel. Products are first enclosed in shrink film, then passed through heat, causing the film to conform securely to the item’s shape. This method enhances product protection, improves appearance, and ensures tamper resistance. Shrink wrapping is widely used in industries such as food, beverages, pharmaceuticals, and consumer goods for bundling, storage, and distribution.
