PE/PP/PS Sheet Production Line: Capable of producing plastic rolls with widths of 650-800 mm and thicknesses of 0.5-2 mm.
This equipment utilizes an SJ75-30:1 or SJ90-33:1 single-screw extruder, a hydraulic automatic screen changer, an adjustable T-type flexible die, a vertical or 45-degree inclined three-roll calender, a three-in-one water temperature controller, a stainless steel cooling bracket equipped with a wide-width adjustable trimmer, a rubber roller traction machine, and a dual-station air-shaft winding machine. The production line employs an Omron intelligent temperature controller (Japan), Siemens low-voltage electrical components, and frequency converters from renowned domestic and international brands.
The produced sheets, after secondary processing, are mainly used for: rigid packaging of fruits, vegetables, and food; outer packaging of cosmetics, hardware tools, and children's toys; and agricultural seedling containers, etc.
Precision Temperature Control and Drying System
Equipped with a hot air dryer, eliminating moisture at the source and preventing air bubbles from forming on the sheets. A three-in-one oil-cooled roller temperature controller provides precise and stable temperature control for the three-roll calender, crucial for achieving a high-gloss surface.
Professional Sheet Forming and Calendering Unit
The combination of a dedicated sheet die and a three-roll calender is specifically designed for sheets ranging from 0.3-2mm in thickness, ensuring uniform material distribution and a mirror-like surface finish.
Excellent Product Thickness Uniformity and Superior Sheet Surface Quality
The precision three-roll calender and temperature control system ensure a high-gloss, flawless mirror-like finish on the sheets, perfectly meeting the appearance requirements of high-end packaging.
High Efficiency and Low Operating Costs
The hydraulic automatic screen changer enables continuous operation without downtime, ensuring production continuity, improving efficiency, and reducing energy consumption and raw material waste.
Stable quality and high yield
The entire system is highly coordinated, with every step from drying to rewinding designed for stability. This results in highly consistent optical and physical properties between batches of the final product, leading to an extremely high overall yield.
The combination of PP/PS material properties and a stable extrusion process gives the products suitable rigidity and impact resistance, making them easy to vacuum form and less prone to breakage during transportation.
Pure and Hygienic
Raw materials are thoroughly dried, and the production process is pollution-free. The finished products are clean, bubble-free, and free of impurities, meeting the hygiene requirements for food, pharmaceutical, and high-end cosmetic packaging.
Optimized Subsequent Processing Efficiency and Cost Savings
Excellent thickness uniformity means even heating and smooth stretching on high-speed vacuum forming machines, significantly improving press efficiency and reducing scrap rates during the forming process, saving customers substantial costs.
Enhanced Packaging Appearance
The high-gloss surface makes the final vacuum-formed boxes crystal clear and brightly colored, perfectly showcasing the contents. This is particularly suitable for cosmetics, electronic products, and gift packaging where a high-quality feel is required.
Stable and Reliable Performance
Highly consistent product performance between batches provides downstream customers' automated production lines with a stable supply of raw materials, reducing downtime and debugging time caused by material fluctuations.
Compliant with Environmental and Safety Trends
PP material itself meets food contact requirements, ensuring the products are safe and non-toxic. At the same time, uniform thickness also means that lightweighting can be achieved while maintaining the same packaging strength, reducing raw material consumption and conforming to environmental protection trends.
