How to Choose a Film Blowing Machine
Key factors to evaluate before purchasing
1. Define Your Product
What end product will you manufacture? Bag type, film type, or material specification determines the machine configuration.
2. Set Output Targets
How many kg/hour or bags/minute do you need? Match machine capacity to your production goals.
3. Check Material Compatibility
Confirm the machine handles your specific raw material — HDPE, LDPE, LLDPE, biodegradable, or recycled compounds.
4. Consider Total Cost of Ownership
Factor in energy consumption, spare parts availability, operator training, and maintenance costs — not just the purchase price.
Common Film Blowing Machine Questions & Troubleshooting
Expert answers and solutions for the most common film blowing machine challenges
A film blowing machine (blown film extruder) is an industrial machine that melts plastic pellets and extrudes them through a circular die to form a continuous tube of molten plastic. This tube is inflated with air to form a thin bubble, which is then cooled, collapsed, and wound onto rolls. It is the primary equipment for manufacturing PE (polyethylene) plastic film used in packaging, agriculture, and industrial applications.
Monolayer machines produce single-layer film at the lowest cost. ABA co-extrusion uses a 3-layer die with A-B-A structure, allowing up to 70% recycled material in the core layer for significant cost savings. 3-layer ABC machines offer the highest film quality with different materials in each layer — ideal for high-barrier food packaging and premium film applications.
Our film blowing machines range from 30 kg/h (mini models) to 300 kg/h (industrial models). The actual output depends on film width, thickness, material density, and the specific machine configuration. For reference, a standard 55mm screw diameter monolayer machine produces approximately 60-80 kg/h of LDPE film.
Yes. ABA co-extrusion machines are specifically designed to process up to 70% recycled content in the core (B) layer while maintaining virgin material surfaces. This reduces raw material costs by 30-50% without compromising film quality. Monolayer machines can also use recycled material but at lower percentages (up to 20%).
Key factors include: die gap uniformity (consistent around circumference), temperature control (within ±2°C across zones), air ring design (even cooling distribution), frost line height (3-5× die diameter), screw wear condition (regular inspection), and raw material quality (consistent melt flow index).
Film blowing machine pricing varies significantly based on configuration. Basic monolayer machines start from approximately $8,000-15,000 USD. ABA co-extrusion machines range from $18,000-35,000 USD. Complete 3-layer lines with IBC, auto winder, and gravimetric dosing range from $40,000-80,000+ USD. Contact us with your specifications for an exact quotation.
Common causes and solutions: Uneven air ring airflow — clean and recalibrate the air ring; Temperature fluctuations — check and stabilize all heating zones; Drafts in production area — enclose the bubble area; Incorrect frost line height — adjust to 3-5× die diameter; Worn screw — inspect and replace if clearance exceeds 1mm.
