Bubble wrap machines produce bubble wrap from high-quality polyethylene resin and are a widely used packaging material. Due to the air-filled middle layer of the bubble wrap, it is lightweight, elastic, and has sound insulation, shock absorption, and wear resistance properties.
-
First, bubble wrap machines can produce three-layer composite bubble wrap, which is a mark of high quality.
-
The performance of bubble wrap machines is very stable and durable, resulting in higher efficiency.
-
A single machine is equipped with both water cooling and air cooling. Water cooling can increase production efficiency and produce bubble wrap that is strong and transparent. It also ensures that the produced film is free of moisture.
-
Bubble wrap machines use different embossing roll molds to produce a wide range of bubble sizes, from 6mm to 32mm.
-
It features a flip-winding mechanism, which makes operation simple and quick.
-
Bubble wrap machines are not selective about raw materials, such as low-density polyethylene (LDPE), LLDPE, and recycled plastics.
-
The entire machine uses frequency conversion speed control, which effectively reduces energy consumption.
Bubble wrap machines mainly consist of five parts: the extruder, the electrical control cabinet, the forming machine, the traction machine, and the winding machine.
-
The extruder is composed of a motor, reducer, screw, barrel, screen changer, mold, and heater. It is mainly responsible for melting, filtering, and extruding the raw materials.
-
The electrical control cabinet consists of a temperature controller, electrical components, and a frequency converter. It is mainly responsible for the centralized electrical control of the entire machine.
-
The forming machine is composed of forming rollers and a vacuum pump. The forming rollers come in three sizes (6mm, 10mm, and 28mm) and can be equipped according to customer requirements. The forming machine is mainly responsible for effectively shaping the molten material extruded from the mold into bubble wrap products, which is a very important step.
-
The traction machine consists of traction rollers, a slitting device, and a film-guiding roller. It is mainly responsible for effectively pulling the bubble wrap from the forming rollers.
-
The winding machine consists of two winding rollers, a flipping device, and a torque motor. It is mainly responsible for effectively winding the bubble wrap from the traction machine, forming it into coils, and then packaging it for storage. This is the final step in bubble wrap production.
