The HDPE was big plastic tanks off of a tractor trailer. We cut them up, from 2'x4' pieces. They have been was 99% chemical free. Some plastic has labels, some has paint, and some has some rust where it sat on the trailer or where the bans went around them. The HDPE plastics are sorted in to different color. Most of it is natural, then white and yellowish tan.
LLDPE we have no weight on. We have blue plastic 55gal drums for sale too.
