Biodegradable Film Blowing Machine

PLA Biodegradable Plastic Film Blowing Machine

A biodegradable film blowing machine is automatic equipment designed by YG especially for making biodegradable films from biodegradable materials. The biodegradable blown film extrusion machine can combine with the printing machine and the biodegradable bag-making machine to form a plastic bag making line. The biodegradable film can be used to make packaging bags, agricultural mulch films, garbage bags, and other products. A high-speed biodegradable film blowing machine is the best equipment for the continuous production of the high-quality, high-yield biodegradable film.

Overview of Biodegradable Film Blown Machines:

Degradable materials: corn starch, PLA polylactic acid, PBAT bio-based degradable materials.

Finished products: LDPE, HDPE, LLDPE, and other plastic films

Production steps: molten material, extrusion, film blowing, drawing, coiling

Application industry: food packaging, printing, garment packaging, industrial packaging, agricultural mulch, etc.

Blown Film Application

Degradable plastic films are currently mainly made of PLA and PBAT as the main raw materials. These two materials are fully degradable plastics with good impact resistance and tensile and elastic properties. In addition to being widely used in disposable films, express packaging, and other fields, biodegradable plastics can also be used in agricultural mulching films, textile fibers, plastic tableware, automotive industry products, and other fields.

The Composition of the PLA PBAT Plastic Film Blowing Machine

The plastic film blowing machine is mainly composed of an extruder, die head, die head, cooling device, foam stabilization frame, herringbone plate, traction roller, coiling device, etc.

The extruder uses a screw conveying to extrude the molten plastic pellets from the die head. The device includes a screw, barrel hopper, deceleration, and drive motor. Its cooling device cools the molten plastic particles to facilitate the next process. The traction roller includes a traction frame, herringbone board, traction roller, traction motor, and other main components. It draws the produced plastic film and rolls it into a roll.

How to Produce the Degradable Plastic Film?

First, put the dried polyethylene particles into the lower hopper, and the particles are pushed forward by the screw of the degradable film blowing machine. During the advancing process, friction occurs between the plastic particles, the screw, and the barrel, and the heat generated heats and melts the plastic particles. The molten plastic flows out of the die, cools, and blows into shape. Finally, it is pulled by a tractor and rolled into a roll to complete the production of the degradable plastic film.
