Paper Valve Bags & Cartons: FSC-Certified Kraft Paper Packaging
Multi-layer Kraft Paper Valve Bags, Corrugated Cartons & Boxes for Industrial & Export Packaging
Paper Valve Bags / Cement Bags
Paper valve bags are small bulk packaging containers made from 3-5 layers of kraft paper through pasted or sewn bottom processes, with a valve port at the top for filling. They are convenient, neat, and well-sealed. In the cement industry, paper valve bags are known as ‘cement bags’ – the traditional mainstream for building material packaging.
All kraft paper is FSC-certified, ensuring sustainable forestry practices. BridgeX Pack also provides various corrugated cartons, boxes, and paper pallets for product outer packaging, transport packaging, and display packaging.
