Polyethylene is widely used thermoplastics in the world.It can be categorized into several subcategories based on its molecular structure, each of which demonstrates unique characteristics that make it suitable for use in particular applications. The most common types of polyethylene are:Low density polyethylene (LDPE) and High density polyethylene (HDPE)
briefly, HDPE film grade resin mainly designed for producing shopping bags, T-shirt bags, grocery bags, food packaging and many so on.
The two advantages are the tensile strength at break & heat-resistant. The tensile strength at break of HDPE is very good, besides, the heat-resistant ratio is high, so HDPE bags can stand heavy subjects & high temperature. HDPE bags are very popular in shopping bags, dotting bags & food packaging due to the above physical feature.
On the contrary, the transparent of HDPE is not good as LDPE. Normally, the appearance of HDPE bags is foggy.
