XIFA is a BRC-certified Chinese valve bag manufacturer with 28 years of experience, producing paper, PP woven, laminated and coffee valve bags for cement, flour, feed, chemical and coffee packaging. Serving trading agents and direct importers across five continents, our factory is a dependable production partner from first sample to full-container shipment.
Consolidate sourcing with a single valve bag manufacturer that produces the full range of structures in-house — no subcontracting, no quality gaps between suppliers.
Every valve bag is engineered around your capacity, filling line and material requirements — from a single kraft paper ply to multi-layer paper-plus-film laminates.

2-ply at 90g/m² per layer, or 3-ply at 80g/m² per layer. Combination structures such as 2-paper-1-film, 3-paper-1-film and 4-paper-1-film are all available depending on the barrier level your product needs.
Pure paper, paper-plus-film, PP woven, heavy-duty film and aluminum-lined structures are all produced in-house — giving you a single source for every material configuration without subcontracting.
Waterproof, oil-resistant, chemical-resistant and low-temperature-stable materials protect contents in demanding storage and shipping conditions.
Valve structure reduces powder leakage and improves seal reliability. One-way degassing valves release built-up gas while blocking oxygen and moisture.
All structures engineered for automatic filling lines. Dimensional consistency bag to bag keeps high-speed lines running without jams or misfeeds.
Bring your own artwork and specification, or work with our team to develop a bag structure from scratch.
We produce against client-supplied drawings and specifications for trading agents, or develop a bag design from your requirements as an ODM partner for direct importers.
Up to 6–8 color flexo/gravure printing with Pantone color matching. Our in-house design team can help refine layout, color separation and structural details before your artwork goes to print.
Minimum order quantity is 4,000 pieces for standard single-color printing and 5,000 pieces for multi-color printing. Free samples are available for existing stock products; custom samples are made to order for a fee.
Standard terms are 30% deposit with the order and the remaining 70% balance settled before shipment.
Two production bases with certified processes and full traceability — from raw material to finished shipment.
Two manufacturing sites running approximately 150 circular looms for consistent, scalable output. Direct factory production means no middleman markup, and our scale supports long-term, high-volume purchasing agreements.
Our facility operates under BRC certification meeting international packaging safety standards. Raw material sourcing and production are controlled under an ISO-based quality management system.
Each bag can carry a unique QR code, giving full production traceability from raw material to finished shipment.
Bags are checked for dimensions, seal integrity, tensile strength and print quality before they leave the factory.
Whether you're placing a trial order or a recurring container-load program, our export process is built for predictable delivery.
We regularly serve industrial packaging buyers across Asia, Europe, Africa and the Americas, working with both trading agents and direct end-users.
Shipments can be arranged by sea, air or land freight depending on your order size, destination and timeline.
The right valve bag depends on your filling material, bag capacity, filling equipment and storage conditions. We offer PP valve bags, woven polypropylene valve bags and paper valve bags — refer to our Specifications section for a detailed material comparison, or contact our engineers for a recommendation.
PP valve bags provide strong moisture resistance, tear strength and durability for heavy-duty applications. Paper valve bags offer better printability and are widely used for food-grade and fine powder packaging. Our engineers can recommend the best option based on your product and filling line.
Yes. All valve bag structures are engineered for automatic filling lines. Dimensional consistency keeps high-speed lines running without jams or misfeeds — our engineers can advise once we know your line specs.
A one-way degassing valve releases CO2 from freshly roasted coffee without letting oxygen in, keeping the coffee fresh while preventing the bag from swelling during storage and transport.
Whether you need standard valve bags or fully customized packaging, share your product, filling equipment, annual volume and destination market with us. Our team will recommend the right solution and provide pricing, samples and lead-time information.
