How to distinguish between PE plastic bag and PO plastic bag

1. The PE material is very soft and transparent, but the thicker PE bag will feel a bit milky white, but it will not affect the product in the see-through bag. The sound is very soft when pinched, and the hand feels very soft. It is used to protect the inner packaging of the product and will not scratch the product; the Po will have a crisper sound and a hard hand, but the same thickness will feel thicker. 2. PO material will be very loud when you pinch it, and it sounds crispy; PE material, there is almost no sound of material friction when you pick it up. When we use plastic cling film and food packaging bags, we should pay attention that this kind of food packaging bags are not strong in heat resistance. Generally, ordinary PE cling film will melt when the temperature exceeds 110 ℃, leaving some human bodies unable to decompose. Plastic preparations. Dongguan Changrongjia plastic bags use plastic wrap to wrap the food for heating. The fat in the food can easily dissolve the harmful substances in the plastic wrap and enter the food. But it can be used to refrigerate non-fat fruits and vegetables. Using plastic wrap to wrap the hair when perming can also cause harmful substances to enter the scalp under high temperature conditions, causing headaches and hair loss symptoms.
