The ABA film blowing machine, compared to a single-layer machine, offers higher production efficiency and better film quality. This is due to the ABA film blowing machine utilizing ABA double extrusion technology, where ‘A’ represents the intermediate material and ‘B’ represents the outer layer material. By using different materials with varying extrusion melting temperatures and melt viscosities, combined with specific plasticizing conditions, the machine forms distinct middle and outer layers in the film, thereby enhancing its physical properties and durability.

Additionally, the production speed of the ABA film blower is faster than that of a single-layer machine, making it suitable for the mass production of film products. It also results in less uneven film thickness and better surface luster. However, for small-scale production scenarios, a single-layer machine is more economical and practical.

Operating Steps
Operating Steps of ABA 2 Layer Co-Extrusion LLDPE HDPE Film Blowing Machine

Safety Precautions During Operation

Do not stand directly in front of the machine during operation to avoid accidental injury.
Ensure no raw materials containing metal impurities or tools that could damage the machine enter the cylinder during feeding.
Avoid wearing gloves while operating rotating machinery to prevent injuries.

Lubrication and Maintenance Check

Regularly check and replenish lubricating oil in the reducer and air compressor.
Inspect the lubrication of all mechanical transmission parts to prevent damage, noise, or drying up.

Pre-Startup Safety Inspection

Check for disconnected or leaking power wiring before startup.
Inspect instruments for damage or abnormalities.
Ensure all parts are safe and functioning properly to avoid production delays or accidents.

Optimizing Film Formation Conditions

Within the film-forming range, increase the forming temperature, cooling air temperature, and swelling ratio to enhance film turbidity and gloss.

Initial Film Formation and Bubble Guidance

Once the mold outlet is uniform, wear gloves and slowly pull the tube.
Close the tube end and slightly open the air regulating valve to allow a small amount of compressed air through the core rod’s central hole.
Carefully guide the bubble through the steady bubble frame, font plate, and traction roller until it reaches the roll.

Adjusting Compressed Air Pressure for Tube Stability

Set the compressed air pressure to an appropriate level to prevent tube breakage while ensuring the membrane tube remains symmetrical and stable.
This ensures consistent production quality.

Cleaning the Extruder and Mold Safely

Use the extruder and compressed air to clean the machine, but avoid damaging the screw or its smooth surface.

FAQs



What materials can an ABA 3 layer co-extrusion film blowing machine process?



An ABA 3 layer film blowing machine is commonly used for processing LDPE, HDPE, LLDPE, recycled polyethylene, and mixed PE materials. The ABA structure allows manufacturers to use recycled material in the middle layer (B layer) while maintaining high-quality virgin material on the outer layers (A layers), helping reduce raw material costs without sacrificing film performance.



What are the advantages of an ABA 3 layer film blowing machine compared with a mono-layer machine?



Compared with a single-layer machine, an ABA 3 layer co-extrusion machine offers better film strength, improved toughness, reduced material costs, and more flexible material combinations. It also enables manufacturers to use lower-cost recycled resin in the core layer while maintaining good appearance and sealing performance on the outer surfaces.



Can the machine produce both LDPE and HDPE film?



Yes. Most ABA 3 layer co-extrusion film blowing machines are designed to handle both LDPE and HDPE materials, depending on the screw configuration and die head design. Some models can also process blended formulations to achieve specific strength, transparency, or stiffness requirements.



What film thickness range can an ABA 3 layer blown film machine produce?



The thickness range varies by model, die size, and application, but most machines can produce films ranging from approximately 0.01 mm to 0.15 mm. Thickness control systems help ensure uniform film quality for packaging, shopping bags, agricultural film, and industrial applications.



What products can be manufactured using an ABA 3 layer film blowing machine?



ABA 3 layer blown film machines are widely used for producing shopping bags, garbage bags, courier bags, agricultural film, industrial packaging film, stretch film, and protective film. The multilayer structure provides better mechanical strength and cost efficiency for high-volume production.



How do you maintain an ABA 3 layer co-extrusion film blowing machine for stable performance?



Regular maintenance includes cleaning the screw and die head, checking temperature control systems, lubricating moving parts, inspecting air rings and cooling systems, and monitoring extrusion pressure stability. Proper maintenance helps reduce downtime, prevent gel defects, and maintain consistent film quality.
