FAQ

Yes, but it requires specific specs. For a 15-150 micron range, you need an adjustable die gap, an 8:1 haul-off speed range, and a flexible air ring. Changeover time usually takes 30-45 minutes. How Adjusting die gap

The extruder screw diameter determines the output capacity (kg/hr), while the die head diameter and Blow-Up Ratio (BUR) determine the film's layflat width. To spec a machine, you should define your target width and thickness first, then work backward to determine the required output and screw size. How do I spec the right extruder size for my target film width?

Extruder size is determined by output demand: a 55mm screw delivers 80–120 kg/hr, while a 90mm screw reaches 300–400 kg/hr. Always spec the machine by working backward from your target layflat width and film thickness. film-blowing-machine-extruder-calculation

By upgrading to servo drive systems (saving 28-34% on haul-offs), implementing OEE monitoring, and optimizing IBC cooling systems, manufacturers can significantly reduce energy draw per kg of film. Energy saving blown film tips

The fundamental cause is transverse thickness variation. Other factors include insufficient cooling, excessive blow-up ratio (BUR), aggressive collapsing frame angles, and uneven nip roller pressure. What is the ideal angle for the collapsing frame to prevent ruffles?

By utilizing ABA three-layer co-extrusion technology, manufacturers can use recycled materials or CaCO3 fillers in the middle layer (B) while maintaining a high-quality finish with virgin materials on the outer layers (A). This significantly lowers material costs and reduces energy consumption. Aba-blown-film-machine-solutions

1. Place the sealing machine in a ventilated dead plate, and keep the room temperature at about 25℃ on weekdays.
2. Every two days of operation, 6# engine oil should be added to each moving part, especially in gears, bearings and gearboxes.
3. Dust should be removed regularly to keep the whole machine clean. Unplug the power supply when not in production and cover it with a cover cloth.
4. If the operation time is too long, the cooling fan should be turned on before shutting down, and shut down after the temperature drops. If the machine is shut down without cooling, the high temperature belt is easily damaged.
5. The high temperature belt should be dusted and dirt removed regularly to ensure the sealing quality.
6. Strictly worn parts should be replaced in time to extend the life of the whole machine. Daily maintenance Details

Both ABA and ABC blown film lines can produce three-layer films, but the main difference between them is the number of extruders and the design of the flow channels. ABA consists of two extruders, and ABC consists of three extruders.Film blowing machines are mainly used to produce HDPE and LLDPE composite plastic bags, which can be used for daily packaging bags, such as T-shirt bags and garbage bags. View details on the differences between ABA and ABC

Extrusion blown film machines offer a core advantage: efficient, continuous production, enabling the cost-effective production of seamless tubular films. However, their disadvantages include the difficulty in controlling film thickness uniformity and limited adaptability to certain raw materials. While efficient, continuous, and cost-effective, they can produce seamless tubular films (suitable for bag making, etc.), their thickness control accuracy is inferior to cast film, and they have certain raw material limitations (e.g., they are not suitable for producing films made of brittle materials).
