Plymor 12" x 15", 2.7 Mil Slider Reclosable Plastic Bags 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. Item width + item depth = bag width. Item height + item depth = bag height. Add an extra 1/2" to the bag width for the item to fit through the slider opening. What is Mil? "Mil" is the plastic thickness. 2.7 Mil = .0027", standard freezer bag gauge. Are the bags food safe? Yes! Because our reclosable bags are made from virgin LDPE (low density polyethylene), they meet FDA requirements for food contact and storage, and are BPA-Free. How to open and close? Simply slide the tab across the bag, the closure does all the work. How to use the bags?

They keep contents fresh and organized, whether for packed lunches or household use. Their resealable design also makes them handy for travel toiletries and craft supplies.
