Product Description
BioPack provides custom tamper proof security evidence bags designed to protect sensitive items during storage, transfer, investigation, banking, logistics, and evidence handling. With high-strength film, permanent security sealing, and visible tamper-evident features, our bags help businesses reduce unauthorized access, improve traceability, and keep important contents secure from collection to delivery.
Whether you need tamper evident bags for documents, security evidence bags for chain of custody, cash deposit security bags, or custom tamper proof plastic bags, BioPack can support custom size, thickness, printing, barcode, serial number, writable panels, and special adhesive seal structures for professional security packaging applications.
When handling valuable or sensitive items, ordinary plastic bags are not enough. Our tamper proof security bags are built with a special seal system that makes unauthorized opening clearly visible. Once sealed, the bag cannot be opened and resealed without leaving signs of tampering.
These bags are suitable for companies and institutions that require secure, traceable, and professional evidence packaging.
