polyethylene is the most commonly used plastic in the world. low density polyethylene is the material used in most poly bags mainly because it provides great strength, clarity and flexibility.

high density polyethylene (hdpe)

high density or hd bags are made out of a thin and light substance, which helps to lower cost of the bags as well as the freight. high density bags are not as clear as low density poly bags however they are very strong, tear-resistant, and stiff. these bags are both strong and economical.
