To save costs and remain competitive in the highly competitive bag manufacturing business, several manufacturers have begun to switch from single-layer extrusion to ABA co-extrusion film blowing machine. Whether making them domestically or importing them, new European rules mandate that bag manufacturers include a high proportion of recycled material in their shopping and rubbish bags.
The Process of Film Blowing Machine
Blown film is a rather easy technique. A process similar to injection molding requires heating plastic pellets until they melt. A thin-walled bubble is created by forcing the plastic through a cylindrical die. A scaffold allows air into the bubble as it rises the tube. The plastic starts to cool down after this duration. It is then pressed into a flattened tube by folding it in on itself when it has cooled enough. A series of rollers are used to wind this tube onto a spool. Before wound onto the spool, the tube might have its edges trimmed, punched, sliced, or printed upon.
If your product needs consistent qualities across its breadth and length, blown films production is the way to go. Although blown films machines are excellent for high-volume manufacturing, they are too expensive to acquire. One minute's worth of blown films may create 130 meters of merchandise. Their film and sheets may range from 250 microns (0.25mm) to as thin as 10-20 microns (0.01mm - 0.02mm). There are a few exceptions to the rule that most blown films is HDPE, LDPE, or Low-Density Polyethylene. The blown film extruder has the limitation of only being able to produce sheets or tubes.

Advantages of Film Blowing Machine
High Quality
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.
Better Film Strength
In addition to drastically cutting down on formula raw material consumption, the ABA machine has the added benefit of producing a 30% stronger 3-layered film compared to a mono-layer film made by a single film extruder.
Some manufacturers choose to employ ABA film blowing machines instead of monolayer machines to make an industrial film or liner bags with better strength for the same thickness, even if they use very few or no recycled resources.
Cheaper
In contrast to ABC's three film extruders, ABA's bare minimum is two. In bag applications where the outer and inner layers may be made of the same material, ABA is more cost-effective than ABC in terms of film strength and material reduction, and it also uses less power and machine investment.
Compared to ABC co-extrusion machines, ABA machines use one fewer film extruder, making them a more cost-effective option for producing 3-layered films for use in HDPE and LDPE bags.
Final Thoughts
Blown films are a production method that uses plastic sheets and tubes to create films. In addition to being completely cylindrical, these sheets or tubes may have additional things placed into them to create practical items such as cling wraps, garbage bags, or shopping bags.
