What Does Poly Liner Mean? Also known as Poly Liner Bags, Poly Liners are made with the same materials as Poly Bags described above.

Where as a Gusseted Poly Bag (Gusseted Poly Liner) would be used to line a box or rectangular package.

Q: What are the electrical properties of polyethylene?

Polyethylene is a good electrical insulator however without an additive it can become easily electrostatically charged.

Q: What are the optical properties of polyethylene?

Depending on the density and the gauge PE can vary between almost transparent and a milky opaque or translucent. LDPE being the clearest followed by LLDPE being slightly less clear and HDPE being the least transparent of all. If you are looking for a high clarity material that would be polypropylene.
