They are nothing but a flexible packaging bag widely used for shipping. Some of the best features of courier plastic bags include tamper-proof, waterproof, POD jackets, and bubble pads. They are made of sturdy and robust polyethylene material and can be fully packed (sometimes even overpacked) and still remain intact. Unlike corrugated boxes, courier bags don't require packaging tape to seal the packets. They come with a peel and seal mechanism—a self-seal adhesive strip.
Esprito Courier bags are made of polyethylene material, which is sturdy. The material makes the bags resistant to tearing, tampering, puncturing, and moisture. Courier bags are sealed from three sides and open from one side. Thus, they can be quickly sealed and packed.
