Naylax, which is known in our country as heavy-duty polyethylene film, is sold in stores in the form of plastic bags. 80% of its composition is made of high-density polyethylene (HDPE), while 20% is low-density polyethylene (LDPE). The inclusion of LDPE enhances the gloss, improves stitching, and increases the softness of the material. In the past, plastic bags in stores and garbage bags were made from low-density polyethylene, but today, heavy-duty polyethylene, or Naylax, has replaced them.
