50, Sabco, Mailing Bags – Self Adhesive, Waterproof and Tear-Proof Postal Bags – Small to Large Sized Grey Plastic Mailing Mail Post Postage Plastic Bags 9 x 12"

Sabco - These poly mailer bags are thick and strong enough for shipping soft-goods, yet these are light enough to save you some money on weight while shipping. Available in a range of sizes for all your needs from extra small to extra large. These bags are manufactured from 50-60 microns thickness 220 -240 gauge while using the co-extrusion process that means a more durable product is formed that combines two textures- one material is extruded and continuously filled with another to form a single product.

Cost-effective: our postal bags are extremely lightweight and have a sticky peel-off strip that saves your time and shipping cost. These are designed to keep the contents secure against moisture, chemicals, opaque, puncturing, tampering, and tearing as these are made strong enough to withstand the rigours of the shipping process. Our mailing bags feature 3 layers of polythene film into one making them very robust, and durable.

Durable and water proof: our grey postage bags are a wonderful choice owing to their high-strength design. You will find these as an excellent value for your money. Ensure confidentiality: our mailing bags are tamper-evident and once the self-adhesive strip is peeled, to mail out your goods and items, and settled, to your customers, sealed, the bag is permanently closed and concealed. Produced using co-extrusion technology. The peel-off strip that is very sticky will seal the bag very well. The peel-off seal is a quick seal that requires no water or licking.
