Traditional palletizing methods for sheet materials, such as stainless steel, polycarbonate and aluminum composites, often have gaps between the sheets and the packaging. These gaps easily lead to friction and slight movement of the sheets during transportation. Over time, such issues can cause edge damage, surface scratching and even moisture ingress, which affect the quality of the sheet materials. The 3-layer stretch film manufacturing machine solves these common packaging problems effectively with its advanced technology.
The 3-layer stretch film manufacturing machine adopts a distinct ABC co-extrusion structure, with each layer undertaking a unique and critical function to ensure optimal packaging performance. The core layer serves as the main support, providing high tensile strength and stretch recovery up to 350% to maintain the stability of the packaging. The inner cling layer is designed to adhere tightly to itself without being tacky on the sheet surface, avoiding any damage to the sheet’s surface. The outer layer is specially processed to offer excellent puncture and tear resistance, effectively protecting the sheets from sharp corners during handling and transportation.
The 3-layer stretch film manufacturing machine wraps sheet bundles with a uniform, pre-stretched film web at a consistent force of 5-8 lb. This stable and uniform wrapping force eliminates air pockets between the sheets, forming a rigid, integrated unit that significantly enhances the bundle's column strength. This structural improvement effectively prevents damage caused by collision or tilting during forklift handling and transportation.
The machine's film has a unique memory function, which can maintain constant tension throughout the transportation process and avoid vibration-induced loosening caused by road bumps or vehicle shaking. Its precision tension control system can accurately adjust the stretching force, preventing uneven stretching of the film that may lead to weak protection points, thus ensuring stable and consistent packaging quality for each sheet bundle.
As a fully automated system, the 3-layer stretch film manufacturing machine effectively replaces inefficient manual wrapping and inferior single-layer film packaging. It not only optimizes film material usage to reduce waste but also greatly improves operational efficiency by saving labor costs. At the same time, it provides reliable and comprehensive protection for various sheet materials during long-distance transportation and storage, ensuring the integrity of the products.
