1. Unitization. The product is tightly and firmly bundled into a unit, making scattered small parts a together and avoiding damage.

2. Primary protection. The product has a very light and thin protective layer around it, achieving the goals of dust, oil, moisture, water, and tamper proof prevention. Avoid damage of items from external force 

3. Fix by pressure.  Wrapping and packaging products into a compact unit that does not occupy space, tightly wrapping the pallets of the products together, can effectively prevent product misalignment and movement. The adjustable tension can make hard products compact, making soft products compact. 

4. Cost savings. Using POF shrink film for product packaging can effectively reduce packaging costs. The cost of POF shrink film is only about 15% of the original paper box packaging. At same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging image.
