Garbage Bag Making Machine

A two-layer blown film machine is a type of plastic extrusion machinery used to produce flexible plastic films. The machine has two extruders that melt plastic resin pellets and feed them into a circular die. The die forms a tubular bubble of molten plastic that is inflated with air to the desired diameter. As the bubble expands, it is cooled by air, which solidifies the plastic into a thin film.

The two extruders are used to produce a two-layer film. Each extruder feeds a different resin into the die, which produces a film with a layer of one resin on one side and a layer of the other resin on the other side. The two layers can be made of different colors, materials, or properties, depending on the desired application of the film.

After the bubble is formed and cooled, it is flattened by a series of rollers and then wound onto a roll. The film can be used for various applications such as food packaging, industrial packaging, agricultural films, and more.

Two-layer blown film machines are widely used in the plastics industry due to their versatility, ease of use, and relatively low cost compared to other film extrusion processes.
