If you're going to wholesale durable industrial pp woven bag made in China, welcome to get quotation from our factory. All customized products are with high quality and competitive price.
Product Overview
Industrial PP Woven Bags are made from woven polypropylene fabric for the handling, storage, and transportation of construction materials, industrial raw materials, recyclables, and other bulk products. Their woven structure provides a practical balance of tensile strength, abrasion resistance, low bag weight, and handling durability. The bags can be supplied in different sizes, GSM levels, printing formats, closures, bottom constructions, and moisture-protection options according to the filling material and loading requirements.

Material Structure & Protection Performance
The bag body consists of woven PP tapes interlaced into a stable fabric structure. Fabric GSM and weave density can be adjusted to balance bag weight, strength, and cost.
For dry, free-flowing materials, non-laminated woven fabric provides ventilation and basic containment. Where protection against external moisture or powder leakage is required, the bag can be supplied with BOPP lamination or an internal PE liner.
Mechanical Performance
Industrial PP woven bags are designed for repeated lifting, stacking, loading, unloading, and transportation. Performance is primarily determined by fabric GSM, tape denier, weave density, seam construction, and bottom reinforcement.
For heavier materials such as aggregates, construction debris, or dense industrial products, higher-GSM fabric and reinforced stitching can be specified. A double-fold or reinforced bottom helps distribute load around the seam and reduce the risk of rupture during handling.
Printing & Surface Finish
Bags can be supplied plain or custom printed for product identification, handling instructions, company information, batch references, or other required markings.
Available printing methods include flexographic and gravure printing, with multi-color printing commonly available. Surface options include uncoated woven fabric, glossy or matte BOPP lamination, and customized bag colors.
Filling, Closure & Handling
The bag structure can be matched to the customer's filling and closing process. Heat-cut or hemmed openings are suitable for conventional manual or automated filling operations, while gusseted constructions can provide additional volume without proportionally increasing the flat width.
Bottom configurations include single- or double-fold stitching, with reinforced stitching available for higher loading requirements. Optional PE liners can be loose or integrated into the bag structure depending on filling and sealing requirements.
Quality Control
Quality control should cover both fabric production and finished-bag conversion. Typical inspection points include PP raw material consistency, fabric GSM, weave density, bag dimensions, printing accuracy, seam integrity, and overall appearance.
For industrial orders, finished bags should also be checked for bottom seam strength, dimensional tolerance, bag weight, and load performance against the approved specification.
