Our full set of supporting units is exclusively engineered to match breathable and non-breathable PE cast film extruders, covering material preparation, extrusion auxiliary, film processing, quality control, and waste recycling. Each unit integrates advanced technology to ensure stable production, high product quality, and cost optimization—making it the preferred choice for global film manufacturers in hygiene, medical, and packaging industries.
Material Preparation Units
●Drying System: As a key drying system for PE resin, it adopts hot air circulation drying technology with precise temperature control (80-120℃). It effectively removes moisture from PE resin and masterbatch, reducing film defects like bubbles and pinholes to below 0.1%. The closed-loop design saves 30% energy compared to ordinary drying systems, with a maximum capacity of 500kg/h to match large-scale extrusion lines.
●Auto Dosing System: This auto dosing system for PE film extrusion is equipped with 4-6 hoppers and high-precision load cells (dosing accuracy ±0.1%). It automatically proportions PE resin, CaCO3 masterbatch, and functional additives, avoiding manual proportioning errors that cause film performance instability. The HMI touchscreen supports 100+ formula memories, enabling quick switching between breathable and non-breathable film production.
●Breathable Compounding Extrusion Machine: As a core unit for breathable film production, this breathable compounding extrusion machine uses a twin-screw structure with precise temperature control (160-200℃). It fully mixes PE resin, pore-forming agents, and modifiers to produce high-quality breathable masterbatch with uniform pore distribution. The output ranges from 100-300kg/h, compatible with different extrusion line capacities.
●Chiller: This chiller for PE extrusion line adopts air-cooled or water-cooled design with cooling capacity 5-50HP. It precisely controls the temperature of extrusion molds and cooling rollers (5-25℃), ensuring rapid film forming and stable thickness. The intelligent temperature control system adjusts cooling power in real-time, saving 25% energy compared to traditional chillers.
●Oil-Temp Machine: As a critical oil-temp machine for PE extruder, it uses thermal oil circulation to control the temperature of the extruder barrel and screw (±1℃). It avoids local overheating that causes material degradation, ensuring uniform melting of PE materials. The high-temperature version (up to 300℃) is compatible with modified PE materials for high-performance non-breathable films.
Film Processing Units
●MDO Unit (Machine Direction Orientation Unit): This MDO unit for PE cast film uses full servo control with a stretching ratio of 1:3-1:5. It performs longitudinal stretching on cast films to enhance tensile strength by 30-50% and improve barrier performance. The multi-roller heating design ensures uniform stretching, avoiding film wrinkling or breaking. It is essential for producing high-strength breathable films and stretch films.
●Micro Embossing Roller + Casting Silicone Rubber Roller: The micro embossing roller for cast film has precision-engraved patterns (pattern depth 0.01-0.1mm) to create decorative or functional textures on film surfaces. The matching casting silicone rubber roller has high elasticity and wear resistance, ensuring uniform pressure during embossing. It is widely used in hygiene films (e.g., diaper backsheets) for softness and breathability enhancement.
●Deep Embossing Roller: This deep embossing roller for PE film has a pattern depth of 0.1-0.5mm, suitable for creating thickened patterns on non-breathable films (e.g., packaging films) for anti-slip and aesthetic effects. The roller is made of hardened steel with a chrome-plated surface, ensuring a service life of ≥1 million meters.
Finishing & Unloading Units
●Winding Unit: This winding unit for PE cast film adopts slip shaft or air shaft design, with a maximum winding width of 2000mm and speed up to 300m/min. The automatic tension control system ensures uniform winding without film stretching or loosening. The dual-station design enables seamless roll change, reducing downtime by 40%.
●Auto Unloading & Shaft Pulling System: This system automatically unloads finished rolls (max weight 500kg) and pulls out the winding shaft, replacing manual operation and reducing labor costs by 50%. The hydraulic lifting design ensures stable unloading, avoiding roll damage during handling.
