1. Raw material selection and formula optimization Main material: High strength PVC waterproof cloth is used as the base layer, and its single-sided waterproof coating can effectively block liquid penetration, ensuring hygiene and safety during the transportation of the body. Reinforcement material: Combining PE woven fabric, PEVA or Oxford fabric as a composite layer, the overall tear resistance is improved through multi-layer composite technology. 2. Structural design optimization Handle system: Adopting a two-stage woven belt design, the force points are dispersed from traditional single points to double sections, and combined with narrow reinforcement belt sewing, the load-bearing capacity is increased to over 200 kilograms. 3. Production process flow Cutting and Composite: Cut PVC fabric and composite layer materials according to the design dimensions, and composite multiple layers of materials into one through hot pressing technology. Stitching handle and reinforcement belt: Using high-strength sewing thread, the two-piece woven belt and reinforcement belt are sewn onto the designated position of the bag body to ensure that the thread density and strength meet the standards. Installation of bag opening and zipper: The U-shaped zipper is pressed together with the bag opening through a hot pressing mold to form an integrated sealing structure; Install double zipper heads to ensure smooth opening and closing. Edge reinforcement and label bag installation: Perform secondary hot pressing reinforcement on the edge of the bag body, sew the label bag and fix it on the surface of the bag body. Hebei Xubing International Trade Co., Ltd., as a professional supplier in the field of emergency rescue equipment, has the following competitive advantages in its PVC corpse bag products: 1. Technological innovation and patent accumulation Patent technology: The company has mastered ultra-high load-bearing and tear resistant technology, and significantly improves product durability by optimizing the handle structure and material formula. Environmental protection and cold resistance: Some products use environmentally friendly formulas, which are odorless and non-toxic when burned; The cold resistance can reach -50 ℃, suitable for extreme environmental rescue. 2. Customized service capability Customization of specifications: Supports adjusting bag size, handle quantity, and color (such as black, orange, etc.) according to customer needs.
