Courier bag 17x30+5cm opaque

Courier bag 17x30+5cm — safe and discreet shipping

When sending goods to customers or documents, the security and privacy of the shipment come first. Our high-quality courier bags measuring 17 x 30 cm, plus an extra 5 cm for the flap, are made of strong COEX LDPE material. They are designed to withstand all transport challenges, protecting your product from moisture, dust, tearing and unauthorized opening.

Thanks to the multi-layer structure — white or light grey on the outside and completely black inside — these bags offer 100% opacity, guaranteeing absolute discretion of the shipment contents. They feature an extremely strong self-adhesive strip (Hot Melt adhesive); once the bag is sealed, it cannot be opened without visible tearing and damage to the bag itself.

These courier bags are essential equipment for shipping via Montenegro Post at significantly lower prices. Instead of paying for expensive cardboard boxes and additional packaging at the post office, you can pack your goods at home or in the office. The bags are extremely lightweight and do not add unnecessary weight to the postage, and the Post and private courier services accept them as standard security packaging for registered shipments and parcels.
