PE plastic bag with CPE plastic bag although there is only one word only, but it is a completely different two kinds of materials, both in appearance and feel of the two have very big difference, want to know what are the specific differences, just read on.
First is in appearance, cpe bag is replaced by high density polyethylene by chlorination reaction of polymer materials, it with the difference between the PE bag? one Color difference: PE bag is transparent, cpe translucent state. two The difference on the sense of touch: PE bag easy soft, cpe palstic bag material is qualitative soft feel is good, not explosive, fold and deformation, can effectively prevent products and bag friction surface scratches. Cpe bag is PE bag evolution body with elastomer, good weather resistance, ozone resistance, aging resistance, chemical resistance, low temperature embrittlement, features such as flame retardant.
Even with white masterbatch PE bags, such as we often use the bag or vest bag, in order of time most will add white masterbatch. But unlike CPE, PE white plastic bags will be reflective, CPE will not.
besides appearance have difference, feel is the same. PE bag, LDPE and HDPE feels stiff, rubbing/rub it sounds a little ring, and CPE bag feels soft.
CPE material not explosive edge, can avoid scratched when packing products such as lenses, chemical resistance, high temperature resistance, good resistance to oxidation, physical properties, elastomer, beautification products, increase product class, and so on
