What Is Shrink Wrap?
Shrink wrap describes a heat-sensitive film that tightly conforms to the shape of a product. Heat causes the film to contract, allowing it to adapt to a wide range of product shapes. Recent advancements in shrink wrap development have diversified film varieties and thicknesses, with thicker films providing greater strength for heavy or irregularly shaped items.
