Zipper Bags, White Block, 4 mil (heavy duty thickness)
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 zipper opening.
What is Mil? "Mil" is the plastic thickness. 4 Mil = .004", thicker than a standard freezer bag and excellent for heavy duty applications.
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.
White Block Feature: The bags in this section feature a white writing block so that you can write part numbers, dates, or other notes directly on the bag with pen or marker.
How to open and close? Separate the two sides of the bag's top lip and use your thumbs to gently pull the zipper track apart. To close, pinch together one end of the zipper and slide your finger and thumb along the zipper. Squeeze excess air out of the bag as you close the zipper.
