- Transportation of Recyclables With high tensile strength and tear resistance, these bags are ideal for transporting heavy recyclables like metals and plastics. The robust design minimizes the risk of rupture during handling.
- Industrial Waste Management Designed for industrial waste, these bags feature chemical-resistant linings that prevent seepage from hazardous materials. Their ability to withstand harsh substances ensures safety and environmental compliance.
- Composting Applications Specialized breathable liners allow airflow for organic waste decomposition while retaining moisture levels necessary for effective composting.
Material Selection and Compliance with International Standards
Choosing the right polypropylene (PP) grade and additives for waterproof woven bags is crucial. This decision is informed by international standards and the specific requirements of waste management applications.
- Polypropylene Grades Based on Standards
- ASTM (American Standards): PP Homopolymer (PP-H) provides high tensile strength and rigidity, making it suitable for heavy industrial waste.
- EN (European Standards): Compliance with EN 13432 ensures materials meet environmental compatibility standards, critical for recycling.
- JIS (Japanese Standards): Emphasizes dimensional stability and durability, vital for long-term waste containment.
- GB (Chinese Standards): Balances cost and mechanical properties for high-performance solutions.
- BS (British Standards): Focuses on chemical resistance, making bags ideal for hazardous waste applications.
- Material Properties and Additive Choices
- UV Stabilizers: Protect bags from UV degradation, ensuring longevity during outdoor storage.
- Antioxidants: Enhance thermal stability, crucial for managing high-temperature waste.
- Anti-static Agents: Prevent static buildup, reducing fire hazards during handling of flammable materials.
- Recommended PP Grades
- PP Copolymer (PP-C): Suitable for flexible, impact-resistant applications.
- PP Homopolymer (PP-H): Ideal for heavy-duty uses due to its superior stiffness and strength.
