20kg Strong Durable PP Woven Valve Bag AD Star Bag
This 20kg PP Woven Valve Bag (Polypropylene Woven Block-Bottom Valve Bag) is an industrial packaging solution specifically engineered for high-efficiency automated packaging operations. this is a typical packaging container used for construction materials, such as putty powder.
I. Core Product Features
**Automated Sealing Design (Valve Port):**
The top of the bag features a valve port, designed for use in conjunction with automated filling machinery. Once filling is complete, the internal pressure generated by the contents automatically compresses the valve opening, achieving a self-sealing effect. This eliminates the need for secondary stitching or heat-sealing, thereby significantly boosting filling efficiency.
**Block-Bottom Construction:**
The square-bottom design ensures that the bag assumes a rectangular block shape once filled. This structure is not only aesthetically pleasing but—more importantly—offers exceptional stacking stability, allowing for the optimal utilization of pallet and warehouse space.
**High Strength and Durability:**
Constructed from woven polypropylene (PP) fabric, the bag possesses superior tensile strength and impact resistance, effectively preventing damage during transportation and handling operations.
**Excellent Protective Performance:**
The surface typically undergoes a lamination process, providing excellent moisture-proof and water-resistant properties. For powdery substances such as the "putty powder" depicted in the images, this structure effectively prevents moisture absorption and subsequent caking.
**Optimized Breathability:**
Despite the presence of a moisture-resistant laminate, the design typically incorporates micro-perforations for air venting. This ensures that air is rapidly expelled during high-speed filling, preventing "bag bursting" while simultaneously guaranteeing that no powder leaks out.
2 Applicable Industries
Due to their robust, moisture-resistant, and stackable characteristics, these packaging bags are widely utilized across the following industries:
1. **Construction Materials (Primary Market)**
Cement, putty powder, dry-mix mortar, stone powder, gypsum powder, etc. These products are typically high-density and prone to generating dust; the sealed filling process facilitated by valve bags effectively minimizes environmental pollution.
2. **Chemical Industry**
Fine chemical raw materials, plastic resin granules, fertilizers, pigments, titanium dioxide, etc. The square-bottom design of these valve bags facilitates efficient container loading for long-distance maritime transport and export trade.
3. **Agriculture & Food**
Animal feed, additives, seeds, flour, starch, etc. The lamination process ensures the purity and dryness of food-grade raw materials throughout the storage period.
4. **Mining Industry**
Packaging for various mineral powders, calcium carbonate, kaolin, and other heavy-duty industrial products.
