Plexiglas as a timber stabiliser

It's a little off-topic, but can anyone confirm or deny whether Woolworths shopping bags are made from HDPE?

After a bit of searching, I'm reasonably sure that they are, but not positive.

I've been saving HDPE to melt down into blocks for woodplastic turning.
It'd be great if WW bags could be used as well, despite their bland colour.
Hair conditioner and shampoo bottles are ideal - they come in a good range of colours. Plastic 2 litre milk bottles and white vinegar bottles etc are good for their translucence, too.

Maybe I am a greenie after all. :D

Edit: A couple of interesting and inspiring proof-of-concept pics. The jug lid, bowl and ladle handle are moulded, the pulley is moulded then turned:

My understanding is that many plastic bags are indeed made of PE.....but it is a softer lower density product than what some bottles are made of.

remember bottles are commonly made of two materials PET and HDPE.

Thanks for that soundman. I'll avoid the Woolies bags, I think, to keep the quality higher. Pity, I have tons of them.

I'm sorting bottles and lids carefully and only using the ones clearly marked with a '2' in a triangle, usually also labelled 'HDPE' as well. I don't want my blanks corrupted with PET, PP or LDPE. Just the good stuff.

Edit: I think I can come up with something a little better than a sandwich maker, too. I'll use the oven, pre-heated. I have an accurate temp probe to suit my DMM, so I can get the temp right without a problem.
