Quality extruder blowing machine provider: The technical details of blown films include one film extruder that feeds the outer and inner layers with the same material. In contrast, a second film extruder will feed a different substance into the intermediate layer. To reduce manufacturing costs and increase efficiency, the central layer of the film might include a larger proportion of recycled material or calcium carbonate compounds (up to 50–70%). Here, we can see an ABA die head with its three layers laid out, with the center layer (B) covered by the inner and outer layers (A), respectively. It is common practice to use higher-quality materials for the outer and inner layers and to include a high-recycle content in the center.

Nip Rolls: The film bubble then passes through a set of nip rolls, which pull the film and control its thickness and tension. Winding System: The solidified three-layer film is then wound onto a roll for further processing or packaging. Key features and capabilities of three-layer film blowing machines include: Multilayer Flexibility: These plastic film blowing machines can accommodate a wide range of polymer combinations, allowing manufacturers to create films with specific properties and performance characteristics. Precise Layer Thickness Control: Advanced monitoring and control systems enable precise control over the thickness of each individual layer within the film.

The key components and operation of a three-layer film-blowing machine are as follows: Triple Extruders: The plastic film-blowing machine has three separate extruders, each one melting and homogenizing a different polymer resin, such as polyethene (PE), polypropylene (PP), and ethylene-vinyl alcohol (EVOH). Combining Die: The molten polymer streams from the three extruders are fed into a specialized combining die, where they are precisely layered and formed into a single circular film bubble. Air Ring: As the three-layer film bubble emerges from the die, an air ring blows cool air onto the exterior of the film, helping to cool and solidify the layers.

A plastic bag making machine is designed to convert plastic film into various types of bags, such as shopping bags, T-shirt bags, garbage bags, and more. These machines can perform functions such as cutting, sealing, and printing on the plastic film to create finished plastic bags ready for use. Plastic bag making machines are essential in the manufacturing industry for the mass production of plastic bags used in retail, packaging, and other applications.
As the plastics and packaging sector strives for excellence, the film-blowing machine will become more crucial in the future, thanks to advancements in science and technology. In terms of R&D and manufacturing of high-end equipment, the local film-blowing machine’s current state needs to be competitive internationally. Still, as the domestic consumer market for film-blowing machines grows, we may expect to see more high-end models. The basis of blown films technology is extruding melting plastic into thin films under controlled circumstances. This technique is popular and extensively used in the plastics processing industry. It obtains essential components for the production and packaging of countless items and finds substantial uses across a variety of sectors. Let’s take a look at where the blown films technique is most often used.
