GAG PET PMMA PP Decoration Film Extrusion Line

Decorative films produced by these extrusion lines are used for:
Furniture surfaces – lamination for wardrobes, kitchen cabinets, and office desks.
Case study: A European furniture brand used the JWP85/65-1500 line to produce PET-based wood grain film, achieving an output of 750 kg/h and a perfect matte surface that meets EN 438 scratch resistance requirements.
Flooring – wear layers and decorative films for LVT, SPC, and WPC flooring.
Case study: A Chinese flooring manufacturer switched from PP to GAG film on the JWS120/65-1500 line. The line ran at 550 kg/h with a thickness tolerance of ±0.01 mm, reducing material waste by 12%.
Automotive interiors – PMMA and PP films for instrument panels, door trims, and center console trim parts.
Case study: A German Tier 1 automotive supplier used this line to co-extrude PMMA/PP film with a total thickness of 0.5 mm, meeting OEM requirements for fogging and UV stability.
Consumer electronics – protective and decorative films for laptop casings, TV bezels, and smart home devices.
The wide width (up to 1300 mm) enables seamless coverage of standard panels, while the thickness range of 0.15–1.0 mm is suitable for both ultra-thin wrapping films and rigid cover layers.

High output for industrial efficiency
JWP85/65-1500 output 600–800 kg/h – suitable for high-volume orders.
JWS120/65-1500 output 500–600 kg/h – suitable for medium volumes with lower energy consumption.

Wide material compatibility
Process GAG, PET, PMMA, and PP on the same line with minimal material changeover time. Dual-motor configuration of 200/45 kW (JWP) and 160/45 kW (JWS) provides independent screw speed control for multi-layer co-extrusion.

Precise width and thickness control
1250–1300 mm finished width – directly fits standard slitting without edge trim loss.
0.15–1.0 mm thickness – achieved through automatic gauge control (AGC) and precision cooling rolls, with online thickness monitoring.

Energy-saving drive system
Main motor power (200/45 or 160/45 kW) matched with high-torque, low-speed extruders, resulting in lower kWh per kg output compared to older hydraulic systems.

Reduced material degradation
Gentle screw design (L/D optimized for heat-sensitive materials like PET and PMMA) minimizes yellowing or gel formation – critical for transparent or light-colored decorative films.

We implement a multi-stage quality control protocol to ensure every roll meets decorative film standards (e.g., ASTM D882 tensile test, ISO 105-B02 color fastness to light).
Online monitoring

Offline laboratory testing (per batch)
Tensile strength and elongation at break (ASTM D882) – e.g., 0.3 mm thick PET film: MD >50 MPa, elongation >120%.
Adhesion (cross-cut tape test for multi-layer films) – no peeling after 3 cycles.
Scratch resistance (PMMA topcoat pencil hardness ≥H).
Weather resistance – QUV accelerated aging (ASTM G154) 500 hours, ΔE < 2.
Chemical resistance – immersion in ethanol, coffee, and oil for 24 hours (no blistering or discoloration).
Real result case
A customer producing GAG-based marble pattern film for kitchen countertops achieved a first-pass yield of 98.6% after implementing online thickness feedback + automatic die bolt adjustment on the JWP85/65-1500 line.

Q1: Which model should I choose if I want to produce PET film at 800 kg/h?
A: The JWP85/65-1500 (600–800 kg/h) is the best choice. Its 200/45 kW motors handle PET's higher melt viscosity. For lower outputs (500–600 kg/h) with PP or GAG, the JWS120/65-1500 is more cost-effective.

Q2: Can you co-extrude three layers (e.g., PMMA/PET/PMMA)?
A: Yes. The "/65" in both models indicates a 45 kW auxiliary extruder for skin or tie layers. With an optional third extruder, A/B/A structures can be produced. We supplied a three-screw configuration to a Turkish flooring manufacturer running at 650 kg/h.

Q3: What is the typical power consumption per kg of product?
A: For the JWP85/65-1500 running at 700 kg/h, average specific energy consumption is 0.28–0.32 kWh/kg (including motors, heaters, and chiller). The JWS120/65-1500 is slightly lower at about 0.26–0.30 kWh/kg.

Q4: How often should the screw and barrel be replaced?
A: With reinforced bimetallic barrels (standard), expected service life is 18,000–22,000 hours for PET/PP materials, and 12,000–15,000 hours for PMMA/GAG (more abrasive). We provide a wear measurement protocol every 6 months.

Q5: What thickness tolerance can actually be maintained at 1300 mm width?
A: With automatic die profile adjustment and online thickness measurement, ±0.008 mm for 0.15–0.5 mm thickness, and ±0.015 mm for 0.5–1.0 mm thickness. A Canadian customer achieved ±0.007 mm tolerance on 0.2 mm thick PP film over 1000 meters of continuous running.

Q6: Do you provide training on quality control testing methods?
A: Yes – we provide on-site operator training covering gauge calibration, CCD parameter setting, and tensile testing. Remote video support is also available.
