Plymor 3" x 4", 4 Mil with White-Block Heavy Duty Zipper 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 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.

How to open and close? For your convenience, the bags top lip is offset, making it easy to separate the sides and open the zipper track. Separate the two sides of the bags 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. Remember to squeeze excess air out of the bag as you close the zipper.

How to use the bags? Our heavy duty 4 mil zipper bags are extremely versatile and practical for a variety of purposes. Perfect for organizing and protecting bulky or sharp items like hardware, tools, or machinery parts. Ideal for secure transportation of heavy or delicate items, whether for shipping or inventory organization.

They feature a convenient write-on block, allowing for labeling and quick identification of contents, enhancing organizational efficiency.
