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 shrink film is preferred for its high transparency, high shrinkage rate, and eco-friendliness. It tightly conforms to the biscuit box, showcasing the product's aesthetics. Additionally, its eco-friendly material aligns with the modern society's demand for green development.

In contrast, PVC shrink film, while lower in price, has slightly lower transparency, shrinkage rate, and eco-friendliness compared to POF shrink film. Particularly in terms of environmental friendliness, PVC shrink film may release harmful substances during heating, which is not conducive to human health.

Therefore, considering aesthetics, environmental friendliness, and safety, we recommend using POF shrink film as the outer packaging material for boxed biscuits. This not only enhances the overall quality of the product but also ensures consumer safety, aligning with the trend of sustainable development in society.
