Flap Lock Poly Bags for Quick Fold-Over Closure

Flap lock bags use an extended fold-over cuff to create a quick, simple closure without requiring a zipper-style top.

How to Choose

1. Measure the product before selecting bag width and length.

2. Keep enough material above the product for the flap to fold over properly.

3. Use a heavier gauge when handling or puncture risk increases.

4. Choose another closure style if a more positive seal is required.

Choosing Flap Lock Poly Bags

Flap lock bags fit applications where quick loading and a simple fold-over closure are more important than a zipper or permanent seal. They work well for lightweight parts, printed materials, apparel, samples, and other compatible products. Because the flap is part of the usable bag length, sizing should leave enough material above the product for the cuff to fold over cleanly. The extended flap folds over the opening to help keep compatible contents contained.

Useful for lightweight products, printed materials, apparel, parts, and other suitable items. Select thickness based on product weight and handling. Allow enough bag length for the product plus the fold-over cuff. Use the current product table and individual item details to confirm available sizes, materials, quantities, and specifications for the exact item you are considering.
