Multilayer Blown Film Machine Features
1. Efficient plasticization: three-screw configuration, uniform melting
Multilayer Blown Film Machine adopts a combination of three sets of high-efficiency screws of Ф105mm×1 + Ф90mm×2, with a length-to-diameter ratio of 38:1. It has excellent plasticization effect and adaptability to various materials, ensuring that each layer of raw materials is fully melted and the interlayer bonding is stable. It is particularly suitable for the production of multi-layer composite functional films.
2. Wide-width design: both production capacity and adaptability
The die head of Multilayer Blown Film Machine supports a film width of 2300mm, which can stably produce ultra-thin films of 12~35g/㎡, meeting the needs of highly transparent, highly flexible and highly breathable products. Suitable for wide winding diameters of Φ600/800/1000mm, suitable for large-scale industrial continuous production.
3. High-speed production: improve efficiency and reduce costs
The maximum operating speed of Multilayer Blown Film Machine is 250 meters/minute. Under the premise of ensuring film cooling and tension control, it can improve the output efficiency per unit time by more than 30%, effectively meet the delivery needs of bulk orders, and reduce unit energy consumption.
4. Intelligent winding system: stable roll change without interruption
Multilayer Blown Film Machine is equipped with a fully automatic center + surface combined winding system, which supports automatic material connection and waste discharge without stopping the machine. The automatic tension adjustment system ensures that the film surface is flat and wrinkle-free, which is suitable for automatic packaging and slitting in the later stage.
5. Precision online detection system: ensure stable quality
Integrated online automatic thickness measurement device (accuracy ±1μm) and online defect detection system, real-time monitoring of film thickness fluctuations and surface defects, improve product yield, and reduce waste film rate to less than 2%.
6. Energy-saving structure: significant reduction in operating costs
The Multilayer Blown Film Machine is equipped with a high-efficiency variable frequency drive system, a hot air recycling device and a low-consumption high-pressure blower, which reduces the energy consumption of the entire line by about 18%. This design has been verified on-site by many customers, with stable operation and significant economic benefits.
1. Baby diaper manufacturing plant: Pampers
The Multilayer Blown Film Machine is used in the Pampers factory to produce highly breathable white PE bottom film. The film weight is controlled at around 15g/㎡, with excellent flexibility and impermeability, improving the overall wearing comfort of diapers.
2. Adult incontinence product manufacturer: Hartmann
At Hartmann's production base in Europe, the Multilayer Blown Film Machine is used to produce multilayer film bottom materials for adult nursing pads and diapers. The film thickness is 28g/㎡, achieving a balance between softness and waterproof performance. The product has obtained the EU CE certification.
3. Pet urine pad manufacturer: OUT! PetCare
OUT! PetCare uses Multilayer Blown Film Machine in its North American factory to manufacture low-weight breathable films, which are widely used in the bottom layer of pet urine pads. The finished products have good adsorption performance and strong edge sealing, which improves the leak-proof effect.
4. Food packaging factory: Amcor
Amcor factory uses Multilayer Blown Film Machine to produce food-grade PE film, which is used as the lining of food composite bags. The film surface is highly clean and the thickness is consistent. It is suitable for packaging fields such as high-end snacks and frozen foods, and meets FDA food safety standards.
5. Medical protective equipment production line: 3M
In 3M's protective clothing manufacturing line, Multilayer Blown Film Machine is used to blow breathable PE film, which is used in disposable isolation gowns, surgical gowns, etc. The gram weight is 20g/㎡, which has the excellent performance of preventing liquid penetration but maintaining air permeability.
6. Building waterproofing mat manufacturer: Sika
Sika uses Multilayer Blown Film Machine to produce the inner layer of the roof waterproofing mat. The film thickness is 30g/㎡, with excellent tensile strength and anti-seepage function, adapting to high temperature and humid environment, significantly improving the protection life of the roof.
Multilayer Blown Film Machine Care and Maintenance
1. Cleaning of the screw system: avoid carbon residue
It is recommended to clean the three sets of screws at high temperature every 400 hours of operation, using LDPE + cleaning material combination, running the cleaning material at low speed at 180~200℃ for 15 minutes, and then blowing the film for 10 minutes without machine to prevent carbon accumulation from blocking the melt channel.
2. Cleaning and maintenance of the air ring and cooling system
Check the outlet air pressure of the cooling air ring once a week, and keep the air pressure at 5~6bar to ensure the stability of the film bubble; clean the air ring filter every month to avoid foreign matter blocking the film bubble deformation or rupture.
3. Calibration of automatic thickness measurement system
It is recommended to conduct calibration test on thickness detection system every two weeks, and use standard thick film samples to check the error, to ensure that the online monitoring error is controlled within the range of ±1μm, and avoid product return due to thickness deviation.
4. Tension setting and lubrication of winding system
Adjust the tension range according to different film weights, calibrate the tension sensor every two weeks, and lubricate the tension arm and winding shaft bearing regularly to ensure stable winding synchronization.
5. Electronic control system and servo inspection
Check the wiring terminals of the electronic control system once a month to confirm that there is no oxidation and looseness; the temperature rise of the servo motor shall not exceed 10% of the rated value. If abnormal, the drive module shall be replaced in time to ensure high-speed and stable operation of the equipment.
