PO what's the difference between a plastic bag and PE plastic bag?

PO what's the difference between a plastic bag and PE plastic bag? PO what's the difference between a plastic bag and PE plastic bag? PO bag and PE bag is different in each aspect, such as the use purpose, texture, density, thickness of bearing, the printing effect, scope, etc. Although PO bag and PE bag use is PE material, but the PO bag use HDPE material ( High density polyethylene) , using the LDPE and PE bag material ( Low density polyethylene) 。 PO plastic bags used by the density of HDPE is 0. 941g/cm³ - 0. 960g/cm³ , and the density of PE plastic bags used LDPE is 0. 91g/cm³ - - - - - - 0. 93g/cm³ 。 Therefore, due to the smaller density, the relationship between PE plastic bags will be more soft and less than PO plastic bags. Here we mainly from two aspects of use and simple sense to explain the PO plastic bags and PE plastic bag. The difference between PO bag and PE bag 1 PO bag and PE plastic bag use different PO plastic bags is mainly used for garbage bags, packaging bags, shopping bags, etc. , because the PO plastic bags is higher, the density of bearing performance is better, with thinner material can produce the packing bag of bearing performance is good, because the demand is very big, so the price of PO plastic bags as compared with PE bag will be cheaper. PE bag is mainly used for gift bags, zipper bag, valve bag, PE bag of flexibility is good, suitable for packing is relatively thin soft products, such as clothing. Garment industry will use a lot of PE bags, such as clothing zipper bags, clothes, shopping bags, clothing valve bag and so on, now most of the Courier bag is made of PE material for co-extrusion production. PO bag for shopping: 2 PO bag and PE plastic bags of different texture PO bag and PE plastic bag in physical resolution is very simple, because of the simple sense of the two bags are very different. Under the condition of the same thickness, PO bag texture reflects a feeling that more hard and brittle, and the surface is rough, there are similar to grind arenaceous textures. While PE bag reflects a feeling of soft and resilient, wax texture and some similar, and to smooth the surface of some PE bag. When rubbing, PO bag will rip the voice of the rip, and PE bag some voice is soft and weak. In terms of transparency, PO plastic bags are usually lower than the transparency of PE plastic bags, so the PO bag should not be used for the need to see the contents.
