Custom-made supermarket plastic bags can use many different types of materials, but as an ordering merchant, how can you identify whether the material of the custom-made plastic bags is what you requested before? We can distinguish them from their respective characteristics.

First, high pressure bags and low pressure bags

Both are made of PE material. The high-pressure bag is soft and durable; the low-pressure bag is stretch-resistant, more stable, and stronger. We can distinguish it in this way: tear the bag, if there are white marks on the tear, it is a low-pressure bag, and if there is no white mark, it is a high-pressure bag. It feels more strenuous to tear off the high pressure bag.

Second, PP bags and OPP bags

It is a very transparent material among all kinds of bags. The PP bag is hard and smooth, and it will make a loud noise when it is slightly shaken. There will be traces after being cut and folded in half; the OPP bag is relatively brittle and easy to tear.

Therefore, if you want to know which material is the custom-made supermarket plastic bag, you can distinguish it through the above methods.
