Composite Valve Packaging Bag

Composite Valve Packaging Bag is developed for cement, dry building materials, and chemical powder packaging. The bag body is based on PP material and can be produced with a composite packaging process to improve load-bearing strength, abrasion resistance, powder leakage control, and stacking performance. Finished sizes support 450-910mm length, 350-600mm width, and 80-180mm bottom width. Square bottom and upright structures can be supplied to match automatic filling lines and bulk pallet transportation. The product supports 1-4 color printing, while patterns, brand marks, and specification details can be customized according to customer requirements. As a cement paper bag and woven bag manufacturer, YINGTONG provides OEM production, bag structure design, and stable supply support for buyers.

Valve Packaging Bag Features:

Stable Valve Filling

Valve Packaging Bag uses a valve structure suitable for fast filling of cement, dry mortar, and similar powder materials. Common filling weights can cover 25kg to 50kg. The valve size can be adjusted according to equipment openings, helping reduce powder leakage, loose bag mouths, and unstable filling efficiency.

Composite Bag Structure

The bag body uses a Composite Packaging Bag process, combining PP woven fabric with a printable surface structure. This improves surface flatness, abrasion resistance, and tensile performance. For long-distance transport, pallet stacking, and repeated handling, the composite structure helps strengthen packaging stability.

Flexible Size Customization

Finished sizes support 450-910mm length, 350-600mm width, and 80-180mm bottom width. The bag can be adjusted according to cement weight, powder density, filling equipment, and pallet size. The square bottom structure helps the filled bag stand more steadily and improves warehouse stacking efficiency.

Clear 1-4 Color Printing

The product supports 1-4 color printing for brand names, net weight, grade information, batch marks, and safety reminders. Clear layout helps warehouse sorting, market recognition, and channel circulation, allowing suppliers to maintain a unified packaging image during bulk shipment.

OEM Bulk Supply

YINGTONG can arrange OEM production according to customer bag type, size, artwork, color, and purchase quantity. Valve Packaging Bag can be adjusted for different cement packaging habits in target markets, helping buyers get a structure better suited to filling and transportation.

Valve Packaging Bag Application:

Cement Production Packing

Valve Packaging Bag is suitable for daily cement packing in factories, including Portland cement, masonry cement, and dry building materials. The valve structure supports fast filling by automatic or semi-automatic equipment. Printed surfaces can show weight, grade, and batch details for easier factory dispatch management.

Dry Building Material Packaging

Dry mortar, putty powder, gypsum powder, and similar materials require strong powder leakage control and stable stacking. Composite valve bags can be adjusted according to material weight and flowability, helping reduce dust pollution caused by handling abrasion and improving warehouse arrangement.

Chemical Powder Transportation

Selected dry chemical powders, mineral powder, and powder additives need packaging with abrasion resistance, printability, and stacking convenience. Valve Packaging Bag can be adjusted by material properties, making it suitable for truckload shipment, warehouse transfer, and regional distribution.

Export Pallet Supply

Export orders focus on packaging strength, clear identification, and pallet loading stability. Composite valve bags can be adjusted by destination market, container loading method, and storage cycle, helping goods maintain a more stable appearance throughout the transport chain.
