I only know the numbers found on plastic containers are for recycle purposes
only. Here is a summary:
Code 1: PET or PETE (polyethylene terephthalate).
You’ll most commonly see this in the thin, clear plastic of bottled water (
or bottled cooking oil, peanut butter, soda, etc.). It’s appears safe for
single use, but these bottles should not be reused, refilled, or heated.
This plastic can be recycled once into new secondary products, such as
textiles, parking lot bumpers, or plastic lumber.

Before even beginning the testing of the ball I performed a bounce test to
compare the bounce of the DHS 3 star plastic ball to the Butterfly 3 Star
Celluloid ball. The plastic ball has a lower bounce peak and is less

of the new ball and also it's plastic material composition.

PVC damage is caused by storing coins in soft plastic flips that contain polyvinyl chloride (PVC.) PVC most commonly manifests as a light-to-dark greenish residue, although it can appear as milky or light grey in color. It has a distinctive "plastic" odor which can range from subtle to strong. I recommend treating coins for PVC residue whenever you can smell PVC on them, even if you don't see the greenish residue yet, because if the coin has a plastic stink, the PVC breakdown process has begun. ... 阅读全帖

No. GLAD does not use any polyvinyl chloride (PVC) plastics in its products.

据我所知,所有的食物Plastic Bag,像三明治袋子,都是LDPE,都不含plasticizer。
薄膜用PVC和plasticizer因为粘性比LDPE好。塑料袋不需粘性。所以也就不需PVC。

You are partially right. Most injection molded plastic are not machinable,
not because they are tough, but because they are too soft or sticky. Most
handgun plastic frame are coldset plastic, which means they will melt at
certain high temperature. However, some rifle plasitc frame are hotset
plastic, so they will burn instead of melting at certain temperature. The
coldset ones are largely not machinable, while the hotset ones largely are.
