Security pockets with safety locks can prevent manipulation and unwanted interventions in many applications, which require the highest security. The safety pockets are made of high-quality film with a thickness of up to 120 micrometers. Ideal for authorities (police, justice, etc.), banks, shipping companies, pharmacies and many more. Transports to the bank or storage of the daytime receipts in the vault can thus be easily implemented. Tried interventions are visible on the adhesive film. A serial number or barcode on the security pockets help with the documentation and stand for maximum security. The use of envelopes is quick and easy. No glue or other tools required.
