Evidence storage bags for forensic use

Sirchie Zip Top Evidence Bags provide secure containment for non-organic items in law enforcement and forensic settings. Each bag is made from 4mil polyethylene and features a self-sealing zip-top closure. The transparent material allows quick visual identification of contents. A pack contains 100 bags for high-volume evidence handling.

Build quality and daily handling

The 4mil polyethylene construction resists tearing during transport and storage. Self-sealing zip-top closures remove the need for separate sealing tools and reduce the risk of accidental opening. Clear walls let officers confirm contents without breaking the seal. Bags accept evidence tape or labels for chain-of-custody documentation.

What this replaces and when to upgrade

These bags replace heat-sealed or taped evidence envelopes where faster sealing and re-access are needed. The 13x18 inch size suits larger items or grouped smaller objects that do not fit in standard pouches. The jump is worthwhile when case volume demands 100-unit bulk supply and zip-top speed over single-use seals.

Questions about this item

What closure standard does the 4mil polyethylene bag use to secure evidence?

The bag uses a self-sealing zip-top design that closes without extra tools and resists accidental opening during handling.

What are the internal dimensions that determine what fits inside each bag?

Each bag measures 13 by 18 inches, giving enough room for larger items or several smaller pieces of evidence.

How do you seal the bag correctly, and what step do users often skip?

Press the zip track fully closed from one end to the other, then run a finger along the seal to confirm it is locked; skipping the verification pass leaves a gap that can open in transit.
