Plastic sheet machines are complete sets of equipment that continuously process polymer resins into plastic sheets/sheets of various thicknesses and widths through extrusion, calendering, cooling, and shaping. Depending on the raw material and product properties, these machines feature diverse screw configurations, mold flow paths, roller structures, and auxiliary equipment. They are widely used in food packaging, stationery, printing, blister packaging, waterproofing, and architectural decoration. The following focuses on three mainstream models: the PET Sheet Making Machine, the PP/PE/PS Sheet Making Machine, and the PE/HDPE Geomembrane Waterproof Sheet Making Machine.
Applicable Raw Materials: 100% virgin PET, recycled bottle flakes, or biodegradable polyesters such as PLA
Product Specifications: Thickness 0.15-2.0 mm, Width 600-1500 mm, Available in single, twin, or multi-layer formats
Core Configurations:
Dedicated low-shear single-screw or twin-screw extruder with a crystallization and dehumidification feeding system to minimize IV (intrinsic viscosity) loss
Hanger-style automatic adjustment die head + hydraulic screen changer ensures melt uniformity and fast screen changes
Three-roll vertical or oblique calender with a constant roller temperature of ±1°C and online thickness adjustment to ±0.01 mm
Online thickness measurement, static removal, edge trimming, and dual-station winding provide fully automatic winding and roll changing
Technical Highlights: Drying-free exhaust technology significantly reduces energy consumption; symmetrical thin-wall rollers improve cooling efficiency, achieving a production output of 800-1000 kg/h
Main Applications: Food-grade blister packaging, electronic trays, printed cards, and permanent antistatic/conductive substrates
2. PP/PE/PS Sheet Machine (Polyolefin/Polystyrene Sheet Production Line)
Applicable Raw Materials: PP, HIPS, GPPS, PE (LDPE/LLDPE/HDPE), and their blended masterbatches
Product Specifications: Thickness 0.2-2.5 mm, Width 700-2000 mm; Single-layer, Dual-layer, or Multi-layer Coextrusion Capable
Core Features:
High-speed, split screw (Taiwanese or European technology) with an L/D ratio of 35-38, ensuring high output (up to 1200 kg/h) and low-temperature plasticization
Fast hydraulic screen changer + T-die with internal plug-type width adjustment for continuous online width adjustment
Three-roller arrangement in horizontal, inclined, or vertical configurations, with servo-controlled gap adjustment accuracy of 0.005 mm; Zoned roll temperature control with PID control
Dual-station friction winding or large-diameter dual-station center winding, automatic metering, and constant tension
Optional Features: In-line corona treatment, antistatic coating, two-color/frosted/striped coextrusion, and EVOH High-barrier laminate
Main applications: disposable lunch boxes, milk tea cup lids, stationery sheets, electronic carrier tapes, decorative frosted boards, pharmaceutical blisters, etc.
3. PE/HDPE Geomembrane Waterproof Sheet Making Machine
Applicable Raw Materials: HDPE, LDPE, LLDPE, EVA, and recycled materials; 2-5% carbon black masterbatch can be added.
Product Specifications: Thickness 0.5-3.0 mm (smooth or single/double matte), Width 4-8 m (depending on die width).
Core Configuration:
Single-screw extruder with a high-length-to-diameter ratio (L/D = 33-38), equipped with high-efficiency exhaust and melt pump to ensure stable melt pressure.
Wide-width coat-hanger die head with built-in throttle bar and "high-low" design ensures uniform thickness and easy matte formation.
Three-roller cooling and shaping system with subsequent multiple cooling brackets; spiral flow channels within the rollers, thermostat-controlled circulation cooling.
Online thickness scanning and automatic closed-loop adjustment; rear dual-track traction, automatic edge trimming, and dual-station friction winding.
Technical Highlights: Output 800-1500 sheets. kg/h, thickness deviation ≤ ±3%; online embossing can create a rough surface to increase the coefficient of friction. Main applications: Anti-seepage lining systems for landfills, tailings ponds, artificial lakes, tunnels, rooftops, and underground waterproofing projects.
Summary
Plastic sheet production lines are developing towards high efficiency, energy saving, multi-layer co-extrusion, online inspection, and intelligent closed-loop control.
PET production lines specialize in food-grade high transparency and high viscosity retention technologies.
PP/PE/PS production lines combine high production output with diverse surface effects, catering to the disposable packaging and stationery decoration markets.
PE/HDPE geomembrane production lines emphasize wide widths, uniform thickness, and durable anti-seepage properties, serving environmental protection and infrastructure projects.
When selecting the appropriate production line, comprehensive consideration should be given to raw material characteristics, product specifications, production capacity requirements, and downstream application standards to achieve the optimal balance between investment returns and product quality.
