A Versatile, Reusable Packaging Solution for Medium-Term Circulation

The Gray Standard PP Woven Bag is a general-purpose polypropylene sack engineered for medium-term and short-term repeated use. With a standard fabric weight of 48g/m², this gray-grade bag strikes an ideal balance between thickness, tensile strength, and cost-effectiveness-setting it apart from ultra-thin single-use alternatives.

Designed for multiple turnover cycles, it is widely used to store and transport agricultural bulk materials, construction sand and gravel, industrial raw materials, and household sundries. The neutral gray fabric offers strong dust and stain resistance, effectively concealing mud, sand, and material residues. Even after repeated loading and hauling, the bags maintain a tidy, presentable appearance-never looking worn or soiled, even after prolonged stacking.

Standardized Weaving & Heat-Cut Production Process

Manufactured under a complete standardized weaving workflow, the process begins with high-purity PP pellets being extruded and drawn into flat yarns through wire drawing machines. These yarns are then woven into base fabric using circular looms, with consistent warp and weft density to ensure stable load-bearing capacity.

All fabric edges are securely locked and reinforced to prevent loose threads during filling, especially with granular materials. After weaving, the gray base fabric is precision-cut to standard sizes using heat-cutting technology, which melts the cut edges to create a clean, sealed finish-effectively preventing edge fraying and unraveling during repeated handling. This is followed by reinforced bottom stitching to prevent seam failure under heavy loads. Custom printing and lamination services are available upon request.

Balanced & Practical Comprehensive Performance

The 48g/m² standard weight delivers a perfect combination of moderate softness and structural integrity, enabling repeated filling, carrying, and stacking without easy tearing. The tight woven texture effectively blocks fine sand, soil, and powders from leaking out.

Wide Universal Application Scenarios

This standard gray woven bag meets most bulk-material packaging needs across multiple industries:

Agriculture – Garden soil, grains, animal feed, and fertilizers

Construction – Yellow sand, crushed stones, and renovation debris

Light Industry – Plastic pellets, mineral powders, and mild chemical raw materials

Available in a full range of sizes to support different load weights, the simple bag mouth allows quick tying and easy handling. Whether for farmers, small factories, or everyday household use, it delivers a cost-effective, reusable packaging solution that balances practicality with long-term cost efficiency.

FAQ

Q: What is the difference between "Virgin Material" and "Recycled Material"? Which should I choose?

A: Virgin material is manufactured from pure PP granules, resulting in bags that are translucent, possess superior tensile strength, and are non-toxic and odorless. These are ideal for food, pharmaceuticals, and high-end chemicals. Recycled material is reprocessed from post-consumer waste; it has a darker appearance and slightly lower strength but is much more economical. It is best suited for general goods like waste, sand, or construction debris where appearance is less critical. We suggest deciding based on your budget and product sensitivity.

Q: What is a "Laminated Bag"? When do I need lamination?

A: A laminated bag features a layer of LDPE (Low-Density Polyethylene) film extrusion-coated onto the woven fabric. If you are packing powders (e.g., flour, putty powder) or moisture-sensitive materials (e.g., fertilizers, chemicals), lamination is essential to prevent leakage and provide a basic moisture barrier.

Q: What is the correct HS Code for woven bags on the Commercial Invoice and Packing List?

A: Woven bags are typically classified under HS Code 6305.33 (of synthetic textile materials) or 3923.29 (of plastics). We can provide a suggested code based on your specific bag composition, but the final declaration should always be confirmed with your local customs broker to mitigate inspection risks.
