Global Leader in High-Efficiency Production Lines for Plastic Sheet & Fiber-Reinforced Radiation Cross-Linked PE Heat-Shrinkable Sleeves (3-Layer)
Engineered for Excellence, Recognized Worldwide
Qingdao Huashida delivers cutting-edge, integrated extrusion solutions trusted by manufacturers globally. Our advanced lines excel in producing both premium PP/PE Plastic Sheets/Boards and high-performance Fiber-Reinforced Radiation Cross-Linked Polyethylene (PE) Heat-Shrinkable Sleeves (3-Layer Structure). Designed for maximum output, stringent quality, and operational reliability, Huashida lines set the industry benchmark.
1. Plastic Sheet/Board Extrusion Line (For Base Material):
Materials: PP, PE (HDPE, MDPE, LDPE), and blends.
Applications: Base substrate layer for multi-layer heat-shrinkable sleeves, industrial sheets, construction panels, packaging.
Key Capabilities:
Width Range: 500mm - 1600mm (Standard), up to 2500mm (Custom)
Thickness Range: 0.5mm - 6.0mm (Precision control ±0.05mm)
Output: Up to 1000 kg/h (Depending on material & thickness)
Core Tech: High-torque extruders, gear pumps for pressure stability, automatic die lip adjustment, precision calendaring/cooling, online thickness gauging (X-ray/IR), automatic winders/slitters.
2. Fiber-Reinforced Radiation Cross-Linked PE Heat-Shrinkable Sleeve Line (3-Layer Coextrusion):
Structure:
Layer 1 (Outer): Radiation Cross-linkable PE (Protective, shrink layer)
Layer 2 (Middle): Fiber-Reinforced Cross-linkable PE (Structural reinforcement)
Layer 3 (Inner): Thermoplastic Adhesive (Sealing layer - EVA, Butyl, etc.)
Key Specifications & Capabilities:
Sleeve Width: 150mm - 1500mm (Post-shrink, customizable)
Thickness Range: 1.2mm - 4.5mm (Total, layer-specific control)
Shrink Ratio: ≥ 3:1 (Standard), customizable ratios available
Reinforcement: High-strength polyester or glass fiber mesh/webbing (Integrated inline)
Radiation Cross-linking: Integrated inline Electron Beam (E-beam) irradiation system (Dose range: 80-200 kGy, precise control). Key for achieving high-temperature resistance, dimensional memory, and mechanical strength.
Output: High-speed production matching sheet line capacity.
Core Tech: Triple-layer coextrusion block/feedblock, precision melt laminating for reinforcement, controlled E-beam irradiation chamber, advanced corona treatment (optional for printing), precision cooling, tension control, servo-driven cutting/winding.
Why Choose Huashida for Heat-Shrinkable Sleeve Production?
Unmatched Production Efficiency:
Integrated design from sheet extrusion to finished sleeve enables continuous, high-volume output.
Optimized coextrusion & inline radiation cross-linking significantly reduces production steps and cycle time.
Robust automation ensures high line speeds and minimal downtime.
Guaranteed International Quality Standards:
Produces sleeves meeting or exceeding ISO 21809-1, EN 12068, CAN/CSA Z245.21, DIN 30672, AS/NZS 4858, and GOST requirements.
Precision layer control ensures consistent adhesive coverage, uniform reinforcement distribution, and reliable cross-linking density.
Critical for corrosion protection of oil/gas pipelines, structural joints, and marine applications.
