The area of product PO membrane is 34% larger than that of PVC. At the same time, the tensile strength of PO film is greater than that of PVC, and the thickness of PO film is greater than that of PVC.
When the degree is reduced by 30% to 50%, the packaging effect of PO film will not decrease because of its high tensile strength, so it is simple to package products with PO film.
The cost of the drill will not increase, and the effect will be better. For example, a PO film with a thickness of 15μ-19μ can replace a PVC film with a thickness of 25μ -40μ.
2. The 2.HDPE plastic bag is soft and transparent, but the thick PE bag will feel a little milky white, but it will not affect the products in the perspective bag.
It feels soft when pinched, and it feels soft. Used to protect the inner packaging of the product from scratching the product. Po will voice brittle, his hands.
It feels hard, but the same thickness will make it feel thicker.
