The technical specifications of PP woven bags primarily include dimensions, load-bearing capacity, and mass per unit area. Dimensions are typically defined by length and width, which can be customized based on the volume and weight of the contents. Common load-bearing specifications include 5 kg, 10 kg, 25 kg, and 50 kg capacities, with each corresponding to specific bag dimensions and weave densities. Mass per unit area (grammage) reflects the thickness of the woven fabric and material usage, serving as a key indicator of product quality.
Key technical performance indicators for PP woven bags include tensile strength, elongation at break, bottom seam strength, and impact resistance. Tensile strength determines the bag's load-bearing capacity during filling and handling; elongation at break reflects the material's toughness and resistance to deformation; and bottom seam strength directly affects the safety of the filled bag. These indicators are typically tested against relevant standards to ensure the product meets practical usage requirements.
PP woven bags can also be engineered with specific functional parameters tailored to different application environments. For instance, laminated woven bags prioritize moisture resistance and sealing performance; products intended for outdoor storage require UV resistance and weatherability; and bags used in industries such as food and pharmaceuticals must comply with hygiene, safety, and environmental regulations. Manufacturers determine these technical parameters based on the intended use to enhance the packaging's reliability and suitability.
