Tamper-Evident Security Bag 23 × 35 cm — 10 Pack

Description

Our core size — the most versatile tamper-evident pouch in the range.

The 23 × 35 cm size holds full A4 documents with margin, property key bundles with paperwork, evidence bags, and most consumer electronics returns.

Each bag is manufactured from 0.07 mm LDPE clear film with a permanent 30 mm security seal at the top.

The seal includes a pre-printed ‘VOID IF TAMPERED — DO NOT ACCEPT IF SEAL IS BROKEN’ indicator strip that activates immediately and irreversibly if the seal is broken or attempted to be re-sealed.

Bags are printed with the ShieldedFlow Supplies brand and our website.

The transparent film allows full visual inspection of contents without opening, making the bag suitable for auditable chain-of-custody workflows.

 

Common applications: cash deposit bags, phone repair check-in, document transfer, vape and CBD retail, key handovers with paperwork, evidence handling, legal document transfer, healthcare paperwork, consumer electronics returns, charity-shop high-value donation logging.
