Samples

These bags have space for you to write a message or label contents.

12"×12" bags have an approximate capacity of one gallon.

The 6-mil and 8-mil bags are more puncture resistant than 2-mil and 4-mil bags.

Hang bags with a hang-up hole and their contents on a peg board or display stand.

Bags with two press-to-close strips keep contents extra secure.

Note: One mil equals 0.001".

Mark-On Fold-Top Leakproof Bags

These bags have space for you to write a message or label liquid contents. For a leakproof seal, turn the bag top over the double-wire closure three times and fold in the wire ends. They have pull tabs so you can hold them open without touching the inside.

Note: One mil equals 0.001".

Tamper-Evident Bags

Securely transport confidential documents, money, and other materials—these bags show clear signs of tampering if they have been opened. Unlike other bags with unreliable adhesives and burdensome keys, these are sealed with locking pins or tags. All have serial numbers on the bag or tag, so you can verify that the receiver got the correct bag. Made of polyethylene or PVC, these bags are strong enough to resist tears and punctures. They also repel water, oil, and solvents to keep contents dry.

Disposable bags are designed for one-time use. All have locking pins that you push into place to create a secure seal. To remove the contents, the bags must be cut open. All of these bags have a write-on address area.
