Silver Metallic Colour-Coded Seals

These package seals measure 50 mm × 20 mm and are made from durable metallized polyester film with a permanent acrylic adhesive backing. Each seal is lightweight (approx. 0.5 g per piece) and features a smooth, reflective silver metallic surface. The adhesive bonds reliably to paper, cardboard, coated plastics, and laminated surfaces without residue upon removal. Designed for repeated handling and postal transit, they maintain integrity under moderate humidity and room-temperature storage. Ideal for sealing envelopes, certificates, product packaging, and internal document folders — especially where visual distinction and secure closure matter.
