For Midweight to Heavy Duty Applications. White Block makes labeling a cinch.
These zip top reclosable plastic bags with white block are the same very high quality as our plain 4 mil zips, featuring excellent seals and reliable zipper closures - PLUS - a white block for writing notes about the bag's contents.
4 Mil is a heavy duty thickness that can be used for packaging your heavy, sharp or valuable items. It can help reduce the frequency of damage caused by scuffs and scrapes, and the puncture resistance is excellent.
Although clear, these bags have good "industrial" clarity. You'll find that your contents will be easily visible, but the primary engineered qualities of this product focus on strength above gloss and clarity.
They are FDA/USDA approved for food and drug contact, as they are made entirely from virgin raw materials.
Like all poly bags, the width represents the opening, and the length represents the length. Our ziplock bag length is calculated from the zip to the bottom of the bag, not including the lip above the zipper.
