We have a Rodofeli brand single screw extruder(60 mm) that we are going to take online in a few days once it is hooked up.

My wife noticed that milkjugs have the HDPE symbol but everyone tells me that turning milkjugs into HDPE film is impossible.

I am going to try pelletizing a few clean jugs and using this mix in our extruder.

But.

I am told the usual mix of linear is a 20% to 30% mix when using virgin HDPE.

I am wondering if the fraility and fragility of a film made using milkjugs can be overcome by using a 50% to 60% mix of linear (Westlake I guess unless someone tells me a better choice?) and a 50% to 40% mix of the pelletized milkjugs to form a better and more resistant film for making T-Shirt bags.

Just wondering since I have no idea what to try other than re-reading my new extruder manual(single screw ).

Yes I have 100% virgin material for regular production but please bear with me as I am very interested in trying out the milkjug HDPE idea as a hobby project when not making regular film for plastic bags.

Hmmm I wonder if it will work if I try 75% to 90% of linear and the rest of milkjug HDPE ?

Any other product that I can add to the pelletized milkjug HDPE to improve linearity, durability, stability?

I know its going to be hard to do but its just something that I have to try and try until I either get a mix that works or I get this idea out of my system.

Thanks for any help that you folks on this forum can toss my way.

Later.

Russ.
