Take you to know the Twin head film blowing machine

Film blowing machine as a key equipment for the production of plastic film, its technical level and production efficiency directly determine the market competitiveness of enterprises. As a kind of high efficiency and high yield film blowing equipment, Twin head film blowing machine has been widely used in the industry in recent yearsy.

1.Working principle of Twin head film blowing machine

The Twin head film blowing machine uses two independent die heads to blow film at the same time, thus doubling the output. Its working principle mainly includes the following steps:

(1). Melt plasticization: the raw material plastic is heated and melted to form a molten plastic with fluidity.
(2). Die head extrusion: The molten plastic is extruded through the die head to form the initial form of the membrane bubble.
(3). Blow molding: By blowing high-pressure air, the membrane bubble is rapidly expanded and formed, and the membrane bubble is drawn to a predetermined length by a traction device.
(4). Cooling and shaping: After the cooling device, the membrane bubble is cooled and shaped quickly to get the final plastic film.
 

2. Features of Twin head film blowing machine

(1). High efficiency and high yield: Twin head film blowing machine through two die heads work at the same time, to achieve double output, greatly improve the production efficiency.
(2). Space saving: Compared with the traditional single-head film blowing machine, the Twin head film blowing machine covers a smaller area and saves production space.
(3). Easy operation: Twin head film blowing machine adopts automatic control system, simple operation and easy maintenance.
(4). Strong adaptability: The Twin head film blowing machine can produce plastic films of different thicknesses and different materials, and has strong adaptability.

3.Application field of Twin head film blowing machine

Twin head film blowing machine has a wide range of applications in the plastic packaging industry, mainly including the following aspects:

(1). Food packaging: The plastic film produced by the Twin head film blowing machine can be used for food packaging, such as bagged food, vacuum packaging, etc.

(2). Medical packaging: Because the plastic film produced by the twin head film blowing machine has good barrier property and sealing property, it can also be used for medical packaging, such as medicine packaging bags, infusion bags, etc.

(3). Agricultural cover: The twin head film blowing machine can also produce agricultural cover film, which is used for farmland insulation, moisturizing, weeding and so on.

(4). Industrial film: The plastic film produced by the twin head film blowing machine can also be used in industrial fields, such as wire and cable insulation, building waterproof materials, automotive interior materials, etc.
