Product Overview
Our PVC Bag is a robust, versatile bulk packaging solution engineered for heavy loads and harsh environments. Made from high-quality polyvinyl chloride (PVC) resin—selected for its exceptional strength, chemical resistance, and durability—it supports safe working loads (SWL) from 1000kg to 2500kg, with a safety factor ranging from 3:1 (standard) to 5:1 (industrial-grade). Unlike PP or PE bags, PVC offers superior resistance to oils, acids, and alkalis, making it ideal for industries handling aggressive or high-value materials (e.g., lubricants, industrial chemicals, construction adhesives). It also features a smooth, non-porous surface that prevents material absorption, ensuring easy cleaning and reuse (up to 10 times), making it a cost-effective and sustainable choice for long-term operations.
Scenario-Based Solutions
Industrial Chemical & Lubricant Shipping
Chemical companies transporting mineral oil, hydraulic fluid, or mild acids need packaging that resists chemical degradation. Our PVC Bag’s chemical-resistant surface prevents oil or acid absorption, ensuring the bag doesn’t weaken over time (even during 6-month storage). The high load capacity (up to 2500kg) also allows for bulk shipping of high-value chemicals, reducing the number of shipments and lowering logistics costs.
Construction Adhesive & Sealant Bulk Handling
Construction material manufacturers producing epoxy resins, concrete sealants, or waterproofing compounds need packaging that can handle viscous, heavy materials. Our PVC Bag’s smooth inner surface allows for easy emptying (no adhesive residue left behind), while the rigid structure maintains shape during filling—ensuring consistent product dosing for on-site use. It also resists damage from construction site chemicals (e.g., cement dust), extending bag lifespan.
Marine & Offshore Logistics
Offshore oil rigs and marine construction projects require packaging that withstands saltwater, humidity, and harsh weather. Our PVC Bag’s water-resistant and UV-stabilized material prevents saltwater corrosion and sun damage, making it ideal for shipping lubricants, cleaning chemicals, or spare parts to offshore sites. The pallet-compatible design also allows for easy handling via ship cranes, reducing on-board logistics time.

Customization Services
We offer comprehensive customization to meet your specific heavy-load and chemical-handling needs:
• Thickness & Safety Factor: Adjust PVC thickness (0.8mm-1.5mm) and safety factor (3:1-6:1) for ultra-heavy loads (e.g., 3000kg industrial machinery parts).
• Chemical Compatibility: Add specialized coatings (e.g., fluoropolymer) for resistance to strong acids (pH <4) or solvents (e.g., acetone).
• Size & Shape: Customize width, height, and gusset size to fit your filling equipment (e.g., 1300x2000x600mm for large-scale chemical tanks).
• Liner Options: Integrate PE or aluminum foil liners for double-barrier protection (e.g., for highly reactive chemicals like chlorine tablets).
• Branding & Safety: Print chemical compatibility labels (e.g., “Resists pH 4-9”), batch numbers, or company logos using chemical-resistant inks that don’t degrade in harsh environments.
