Poly Bags
Most plastic bags are made from polyethylene or polypropylene resins. Poly bags are bags derived from either of the two plastic resins, although the term usually refers to polyethylene bags. Poly bags are available with sliding lock zippers; in the absence of a zip seal they can also be sealed with heat.
Polyethylene is often the material chosen to make shopping bags. Plastic shopping bags are more durable in wet conditions than paper bags. Although shopping bags are available in basic designs, many retailers choose to customize their bags with the name and symbol of their store in order to provide cheap advertising. Many people reuse shopping bags, either as garbage bags or in order to transport or store other goods.
Poly bags are often used for food preparation and storage because they are water-resistant. They come in a variety of sizes, including snack, sandwich, quart, and gallon. Zip seal varieties can be used to hold liquid materials without the risk of leaking.
