What is the relationship between output capacity and film width in blown film machines?

1100 AB film blowing machine in customer's workshop

2025-12-29

This equipment adopts AB double-layer co-extrusion technology. Through two independent extrusion systems, it can produce plastic films with higher strength, better barrier properties, and superior appearance quality, making it an ideal choice for high-quality packaging material production.

This 1100 AB film blowing machine is designed to meet diverse packaging needs.

Double-layer co-extrusion process

Independent feeding from two hoppers (A and B) allows for combinations of different formulations or colors for the inner and outer layers, significantly improving the film's toughness, tensile strength, and transparency.

Intelligent control system

Equipped with a precise PLC touchscreen and temperature controller, it can monitor output (e.g., 56.44 kg/h) and linear speed (e.g., 13.9 m/min) in real time, ensuring stable production and uniform film thickness.

High-efficiency winding and cooling

Featuring an advanced cooling air ring and a dual-station automatic roll-changing mechanism, it maintains a smooth winding effect even under wide-width (1100-type) operations. Wide range of applications: Suitable for producing supermarket shopping bags, roll bags, industrial packaging films, etc., significantly enhancing the market competitiveness of products while reducing raw material costs.

Expert Insights & FAQ

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
