These 13" x 18" reclosable bags feature a large white write-on block and 4 mil LDPE construction for heavy-duty industrial parts storage, tool room kitting, and bulk hardware organization. The white panel accepts marker or pen for direct labeling, eliminating adhesive labels in high-turnover bin environments.

Features

• Large white write-on block — accepts marker or pen for direct identification


• Reinforced side-welded zipper — locks in a single smooth motion for reliable reclose


• 4 mil gauge — industrial-duty thickness for heavy parts and abrasive contents

• 100% virgin LDPE resin — consistent clarity and seal quality throughout

Material Notes

Manufactured from 100% virgin Low Density Polyethylene (LDPE) resin meeting FDA/USDA specifications. The 4 mil gauge provides heavy-duty puncture and tear resistance appropriate for metal parts, fastener lots, and hard industrial components. The white write-on block panel is integrated into the bag face and accepts most permanent markers and ballpoint pens for direct labeling. All gauges are nominal.

Use Case Notes

The 13" x 18" format is well-suited for larger parts kits, multi-item hardware lots, and bulkier MRO components that exceed the capacity of smaller bag formats. At 4 mil, this bag holds up to repeated insertion and removal of heavy or abrasive parts without tearing at the seams or zipper zone. The write-on block eliminates the need for separate adhesive labels, reducing per-unit packaging cost in high-volume bin operations.

Common Questions

Q: What type of marker works best on the write-on block?
A: Permanent markers such as Sharpie-style fine-point markers provide the clearest, most durable writing. Ballpoint pens also work on the white panel surface.

Q: Can contents be visible through the bag?
A: Yes. The bag body is clear LDPE. Only the white write-on block panel is opaque, allowing full visibility of contents through the clear film area.

Q: Is this bag FDA compliant for food storage?
A: Yes. These bags are made from LDPE resin meeting FDA/USDA specifications and are suitable for direct food contact applications.
