Shrink film is a common type of packaging film. In packaging applications, the heat shrink phenomenon is often utilized to achieve wrapping or bundling effects.

POF Shrink Film (Polyolefin Oriented Film), also known as BOPE Shrink Film (Biaxially Oriented Polyethylene Film), is a shrink film produced by biaxially stretching polyolefin using a double bubble method.

Boxed biscuits are typically wrapped with heat shrink film, and the choice between POF (polyolefin) shrink film and PVC (polyvinyl chloride) shrink film is crucial.

POF film packaging often encounters the problem of pouch breakage during the passage through the heat shrink oven, significantly affecting the packaging effectiveness and quality of the products.

Considering aesthetics, environmental friendliness, and safety, we recommend using POF shrink film as the outer packaging material for boxed biscuits.

By appropriately adjusting the number of exhaust holes, heat shrink oven parameters, and selecting high-quality POF film, we can effectively resolve the issue of pouch breakage during the passage of POF film packaging through the heat shrink oven, thereby enhancing the packaging quality of the products.
