Advantages of Film Blowing Machine
 

Exceptional Barrier Performance
Multi - layer film blowing machines enable the creation of films with remarkable barrier properties. By laminating different polymer layers, these machines produce films that can effectively impede the transmission of oxygen, moisture, and other harmful substances.

 

Enhanced Mechanical Robustness
Films produced by these machines exhibit superior mechanical strength. The combination of various polymers in each layer optimizes properties such as tensile strength, puncture resistance, and flexibility.

 

Tailored Film Architectures
These machines provide unparalleled flexibility in designing customized film structures. Manufacturers can precisely select from a diverse range of polymers and additives.

 

Cost - Efficiency in Production
Despite their advanced features, multi - layer film blowing machines offer cost - effective production solutions. Using a blend of polymers allows manufacturers to reduce material costs while maintaining film performance.

 

Environmental Sustainability
In an era of growing environmental awareness, multi - layer film blowing machines contribute to sustainability. They enable the use of recycled polymers in film production, promoting the circular economy.

 

Applications of Film Blowing Machine

Production of Plastic Packaging Bags
This is the most common use of film blowing machine. Plastic packaging products such as shopping bags, garbage bags, vest bags, roll bags, etc. on the market are almost all produced by film blowing process.

 

 

Agricultural Film
Agricultural greenhouse film, ground film, cling film, etc. are also important application areas of film blowing machine. This type of film needs to have strong UV resistance, aging resistance and tensile strength, and is usually produced by a large-caliber agricultural film blowing machine.

Industrial Film

Industrial packaging has high requirements for film thickness, toughness, and chemical stability. Common applications include heavy-duty packaging bags, shrink films, wrapping films, anti-corrosion films, etc. High-strength film blowing equipment can meet these needs.

Daily Necessities Film

For example, tablecloths, shower curtains, folder covers, etc., these soft film products used in daily life are also mostly made by film blowing machines. By controlling the formula and film blowing process, soft, transparent, and decorative film materials can be obtained.

Medical Packaging Film

Medical devices, drugs, etc. have extremely high requirements for the safety and sealing of packaging films. Multi-layer co-extrusion blown film technology can achieve functions such as sterility, impermeability, gas barrier, and stretch resistance.

 

 

Key Steps in Film Blowing Machine Process

 

 

 

Feeding & Melting: Polymer granules are fed into the extruder and melted by controlled heating.

 
 

Extrusion: The molten material passes through a circular die to form a continuous tube.

 
 

Inflation: Compressed air is blown inside the tube, creating a bubble that defines the film’s thickness and width.

 
 

Cooling: Air rings or internal cooling systems solidify the bubble.

 
 

Flattening: The bubble is collapsed into double-layer film by rollers.

 
 

Haul-Off & Winding: The film is pulled at a set speed, trimmed, and wound into rolls for packaging or further processing.

FAQ

 

 

Q: What kind of materials are processed in film blowing machines?

A: Film blowing machines can process a wide range of materials, including high-density polyethylene (HDPE) and biodegradable polylactic acid (PLA), among others, to create films that meet various industry specifications.

Q: What is the process of blown film machine?

A: Plastic melt is extruded through an annular slit die, usually vertically, to form a thin walled tube. Air is introduced via a hole in the centre of the die to blow up the tube like a balloon. Mounted on top of the die, a high-speed air ring blows onto the hot film to cool it.

Q: What are the parts of a film blowing machine?

A: Parts include: screw and barrel, motor, inverter, heaters, die head, winder, and tower. The main motor may have frequency control of motor speed to improve speed regulation and save electricity.

Q: How does blown film extrusion differ from cast film machine?

A: Blown film extrusion inflates a tube into a bubble, while cast film extrusion involves extruding molten polymer onto a chilled roller. Cast films have better clarity and uniform thickness, but blown films offer superior strength.

Q: What is the maximum film width achievable with blown film extrusion?

A: Widths can range from a few centimeters up to several meters, depending on die size and equipment design.
