Testing standards for industrial woven bags are primarily based on relevant national and industry standards for packaging materials; commonly applied standards include *GB/T 8946: General Technical Requirements for Plastic Woven Bags* and *GB/T 8947: Test Methods for Plastic Woven Bags*. These standards set forth clear requirements regarding raw materials, visual quality, dimensional tolerances, and fundamental physical properties, serving as key benchmarks for product quality assessment.
Mechanical property testing focuses on metrics such as tensile strength, elongation at break, bottom seam strength, and impact resistance. Tensile strength measures the bag's load-bearing capacity under stress, while bottom seam strength is directly linked to safety during use. Additionally, the woven fabric's mass per unit area and warp/weft density are tested to ensure structural stability and consistent performance, thereby meeting the basic requirements for industrial packaging.
Inspections regarding functionality and visual quality focus on identifying defects such as damage, stains, skipped stitches, color variations, and printing errors. For industrial woven bags designed for specialized applications-such as laminated or moisture-proof bags-additional specific tests are conducted to evaluate properties like impermeability, aging resistance, and weatherability. Through such comprehensive, standardized testing, the reliability and safety of industrial woven bags during actual transport and storage can be effectively ensured.
