Product Overview

Tailored for the strict packaging and transportation demands of the chemical industry, our PP woven bags for chemical raw materials adopt high-purity polypropylene raw materials and precision weaving technology, serving as reliable packaging solutions for powdered, granular and crystalline chemical products. Designed to adapt to long-distance transportation, stacked storage and harsh industrial environments, these bags balance superior durability, safety and cost-efficiency, widely recognized in the chemical and new material industries.

The product features outstanding industrial-grade performance. Adopting professional weaving craftsmanship, the bag body boasts high tensile and tear resistance, effectively avoiding cracking, deformation and material leakage during hoisting, stacking and rough handling. With excellent chemical stability, the bags resist erosion from most weak acids, weak alkalis and common chemical solvents, fully protecting internal chemical raw materials from deterioration and contamination. The optional laminated coating enhances waterproof, moisture-proof and dust-proof performance, solving the caking and quality deterioration problems of hygroscopic chemical materials.

Focusing on industrial packaging protection optimization, our chemical-grade PP woven bags support customized inner lining design to upgrade moisture and waterproof performance. The professional inner lining fits closely with the bag body, forming a fully sealed protective layer that effectively isolates external moisture, water vapor and dust. It provides all-round protection for highly hygroscopic, easily damp and deteriorated chemical raw materials, avoiding material caking, mildew and quality loss during transportation and long-term storage. The bags adopt brand-new high-quality PP raw materials to weave the base fabric, which features excellent tensile strength, toughness and deformation resistance, maintaining stable bearing capacity during long-term stacking and frequent handling. Matching with specially selected corrosion-resistant sewing threads, the stitching parts can effectively resist chemical erosion and damp corrosion, avoiding thread breakage and bag splitting, and greatly improving the overall durability and safety of the packaging bags.

Lightweight yet load-bearing, the bags feature a high strength-to-weight ratio that cuts overall packaging and logistics costs. They are applicable to soda ash, alumina, zinc oxide, sulfur, chemical fertilizers and various industrial powder and particle materials. In addition, the materials are recyclable and eco-friendly, complying with global industrial environmental standards. Customizable sizes, printing logos and thickness specifications support personalized OEM services, meeting diverse batch packaging demands for chemical enterprises.

FAQ

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.

Q: Is an inner liner necessary? Can I choose the type?

A: Not necessarily. However, if your product is extremely hygroscopic (e.g., fine chemical powders), we strongly recommend adding a PE inner liner inside the woven sack for significantly enhanced moisture protection. We offer both HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene) liners; you can choose the specific type based on your product's requirements and intended use.
