Plymor Flat Open Clear Plastic Poly Bags, 15" x 24" What size bag to order? Measure your item by its width, height, and depth because the plastic bag needs to fit all the way around it.

"Mil" is the plastic thickness. 2 Mil = .002", standard sandwich bag thickness. 4 Mil = .004", thicker than a standard freezer bag and excellent for heavy duty applications. Are the bags food safe? Yes! Because our flat bags are made from virgin LDPE (low density polyethylene), they meet FDA requirements for food contact and storage, and are BPA-Free. How to use the bags?
