Default Plastics?

Hopefully this question is in the correct place!

Recently I saw patio furniture made from a heavy durable plastic. Shaded in numerous colors. I was told it is made from recycled materials such as the plastic one gallon milk jugs.

Can anyone tell me the correct name of this material?

High density polyethylene The Different Types of Plastic and Their Number Classifications (Codes) - Quality Logo Products, Inc.
My wife and I worked at a sports clothing factory a number of years ago that made (polar) fleece jackets among other things. The manufacturer of the cloth told us that the fleece was made from recycled pop bottles.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

YEP - I'm looking at the bottom of a milk jug now - it has "HDPE" stamped on it, which; as Chuck stated is High Density PolyEthylene. Milk jugs are made from virgin material, but chairs can be made from a matrix containing regrind. I use HDPE virgin 55% + regrind 45% to make-up the recipe for my concrete forms. In concrete forms, the regrind is considered to be utilized in an "INERT APPLICATION", whereas regrind cannot be used in food or drink storage applications - you wouldn't want to be drinking milk from a container that had regrind previously used for motor oil or benzine.

Thanks guys. I use sheets of HDPE for kitchen products that I fab and sell. My local supplier didn't know what I was asking for. I guess they don't have access to the reprocessed material.

I don't deal with the raw ingredients of regrind. My concrete forms are injection-molded and the virgin and regrind raw materials are stored in gaylords and they look like rabbit food-shaped pellets for easy feeding into the machinery. Sheet plastics are widely available, but I've never personally gone-out looking for sheets of regrind.
