You will hear “poly” all over the packaging world. Here is what it actually means.

What does “poly” mean?

“Poly” is packaging slang, generally referring to the plastic polyethylene. But it is a broad term — there are seven common types of “poly” plastic:

• Polyethylene Terephthalate (PET or PETE)
• High-Density Polyethylene (HDPE)
• Polyvinyl Chloride (PVC)
• Low-Density Polyethylene (LDPE)
• Polypropylene (PP)
• Linear Low-Density Polyethylene (LLDPE)
• Polystyrene / Styrofoam (PS)

QIS mainly stocks HDPE, LDPE and LLDPE products — including poly bags, layflat tubing, resealable bags, stretch wrap and checkout bags.
