1. Specially designed screw, better plasticization efficiency

The Multi Layer Blown Film Machine adopts a screw structure specially developed for multi-layer co-extrusion film. Screws of different diameters perform their duties under the cooperation of independent drive motors, and handle the melting and mixing of different raw material layers respectively. Through high shear and low-temperature plasticization technology, the plasticization uniformity is greatly improved, the stratification problem is effectively prevented, and the longitudinal and transverse tensile properties and mechanical stability of the film material are improved.

2. Spiral channel cooling roller, more uniform cooling effect

The roller adopts a spiral channel water cooling design, so that the cooling medium is evenly distributed along the entire cylinder in a spiral shape, avoiding the occurrence of local overheating or overcooling, thereby ensuring the stability of the film blowing cooling process, improving the flatness and smoothness of the film, and is particularly suitable for film products that require high transparency and uniform thickness.

3. Energy-saving design covers all aspects, lower operating costs

Multi Layer Blown Film Machine adopts a number of energy-saving solutions as a whole: including high-efficiency variable frequency drive system, servo control system, insulation heating coil, waste heat recovery, etc., which greatly reduces energy consumption while ensuring high performance output. The energy-saving operation mechanism not only meets international green production standards, but also saves a lot of production costs for enterprises, with a very high cost-effectiveness ratio.

4. Optimized film penetration path, more convenient operation

The film penetration route of the whole machine has been optimized for many times, making the process from melt discharging to blow molding, cooling traction, edge trimming, and winding smooth and coherent. Operators are more efficient when changing film types or debugging Multi Layer Blown Film Machine, greatly reducing debugging time and film waste, and improving production rhythm.

5. Automatic center surface winding system, automatic material splicing

Multi Layer Blown Film Machine is equipped with a fully automatic surface winding and splicing system, which can automatically adjust the winding speed and pressure according to the change of film tension, realize automatic splicing and changing of rolls under high-speed operation, ensure continuous and stable operation of the production line, without frequent manual intervention, effectively reducing labor costs and production risks.

6. Online edge trimming and recycling system

Multi Layer Blown Film Machine is equipped with intelligent edge trimming tools and edge recycling pipeline systems. During the film production process, excess edge trimming is carried out in real time and recycled to the extrusion system for reuse, reducing material waste, maintaining edge neatness, and improving the final appearance and quality control capabilities of the product.

7. Online automatic thickness measurement system and defect detection function

Multi Layer Blown Film Machine integrates a high-precision online thickness gauge and an intelligent visual defect recognition system, which can monitor the thickness uniformity and surface defects of each batch of films in real time, realize data feedback adjustment closed-loop control, ensure that each batch of products meets customer quality standards, and effectively improve the qualified rate of shipment.

8. Auxiliary pull-out system to improve winding efficiency

Multi Layer Blown Film Machine is equipped with an auxiliary pull-out mechanism, which can quickly realize the replacement of the reel and the unwinding of the film after completing the winding of a roll of film, improve production efficiency, reduce downtime, optimize personnel operation convenience, and improve the overall ergonomic design level of Multi Layer Blown Film Machine.

1. Baby and adult diaper bottom film

Multi Layer Blown Film Machine can produce PE films with strong breathability, high strength and light weight, which are used for the bottom film layer of baby and adult diapers.
