Technical Specifications of Plastic Security Capsules

A quality security seal plastic capsule should have the following characteristics:

High impact resistance, UV resistance (for outdoor use), disposable breakable structure and the ability to leave no clear tamper marks.

Polypropylene (PP) or polyamide (PA) is usually used in production. These materials are both durable and suitable for injection molding.

The precision of the lock mechanism is critical in terms of quality. Too loose design creates vulnerability; A very tight design creates difficulties in application.

Difference Between Security Seal Plastic Capsule and Other Seal Systems

Metal seals offer high strength but are costly and heavy. RFID-based electronic seal systems provide advanced monitoring, but installation and system costs are high.

Plastic seal capsules are:

Therefore, it is advantageous for both the public and private sectors in terms of cost/performance balance.
