        EPE foam bag production process<\/strong><\/em><\/span><\/h3>\n

        The EPE foam bag (pearl cotton bag) production process mainly consists of two steps: foaming to produce the material in roll form and subsequent processing to form the bags. The core process uses low-density polyethylene (LDPE) pellets, which are physically foamed (usually using butane gas) and extruded into pearl cotton rolls. These rolls are then cut and heat-sealed to form bags, producing a lightweight material with good cushioning properties.<\/span><\/p>\n

        Production of EPE pearl cotton rolls (Core material processing)<\/strong><\/em><\/span><\/h4>\n
          \n
        1. Raw material preparation: Low-density polyethylene (LDPE) pellets, anti-shrinkage agent, nucleating agent and physical foaming agent (such as butane) are mixed in a certain ratio.<\/span><\/li>\n
        2. High-temperature plasticization and extrusion: The mixture is melted and physically foamed under high pressure and high temperature in the foaming machine.<\/span><\/li>\n
        3. Mold forming: When the molten plastic is extruded from the mold (die head), the pressure decreases, and the foaming agent rapidly vaporizes, causing the polyethylene to form countless tiny pearl-like pores, thereby expanding into foam tubes.<\/span><\/li>\n
        4. Cooling and rewinding: The formed foam tubes are shaped, cooled, cut into rolls, and finally heat-treated and packaged.<\/span><\/li>\n<\/ol>\n

          Post-production processing of EPE pearl cotton bags (Finished product manufacturing)<\/strong><\/em><\/span><\/h4>\n
            \n
          1. Film lamination\/Heat bonding (As required): For bags requiring greater thickness or special composite structures, thin rolls are heated with a hot air gun and then bonded together to increase thickness.<\/span><\/li>\n
          2. Cutting: Wide pearl cotton rolls are cut into the required width and length for the bags using a cutting machine.<\/span><\/li>\n
          3. Bag making (Heat sealing): The edges of the pearl cotton sheets are heat-sealed at high temperature using a heat-sealing machine (edge sealing machine) to form bags.<\/span><\/li>\n
          4. Punching\/Folding (Optional): Punching is performed to create handles; or specific folding configurations are made.<\/span><\/li>\n<\/ol>\n

            Characteristics of EPE pearl cotton bags<\/span><\/p>\n

              \n
            1. Physical foaming: Butane gas is used for physical foaming, which is non-toxic, leaves no residue and is environmentally friendly.<\/span><\/li>\n
            2. Pearl-like structure: Dense texture, with the characteristic of becoming more fluffy during use, superior to ordinary foam.<\/span><\/li>\n
            3. High performance: Lightweight, shock-resistant, impact-resistant, moisture-resistant, heat-insulating and sound-insulating.<\/span><\/li>\n<\/ol>\n\n\n\n

              Printing on PE foam bags<\/strong><\/em><\/span><\/h3>\n

              Printing on EPE (expanded polyethylene) foam bags primarily uses flexographic or screen printing methods. The key point is that the smooth surface and anti-aging\/anti-static coating of EPE require special treatment (such as corona treatment) to enhance ink adhesion. Environmentally friendly water-based inks are commonly used, suitable for printing logos, barcodes, or simple anti-static symbols, achieving flexibility, shock resistance, environmental friendliness, and brand promotion.<\/span><\/p>\n

              Printing methods:<\/strong><\/em><\/span><\/p>\n

                \n
              1. Flexographic printing: Suitable for mass production, fast printing speed, thin ink layer, and environmentally friendly.<\/span><\/li>\n
              2. Screen printing: Suitable for small quantities, a wide variety of products, and large patterns, with a thicker ink layer.<\/span><\/li>\n
              3. Surface treatment (Important): EPE is a low-surface-energy material, and corona treatment is often required before printing to alter the surface tension, helping the ink adhere more firmly.<\/span><\/li>\n
              4. Ink selection: Using environmentally friendly water-based inks ensures that the printed bags meet environmental requirements.<\/span><\/li>\n
              5. Customizable content: Common customization options include company logos, anti-static symbols (blue), contact information, and material symbols.<\/span><\/li>\n
              6. Printing environment: Printing is usually carried out sheet by sheet before bag making, or continuously directly on EPE rolls.<\/span><\/li>\n<\/ol>\n\n\n\n
