What Are The Basic Equipment For Plastic Bag Production Line?

The basic equipment of the plastic bag production line mainly includes blow-film machine, bag making machine and printing press. The following is a detailed description of the core equipment, together with supplementary information on ancillary equipment:
Core Equipment
Diaphragm blower:
Function: Hot-melt plastic granules (such as polyethylene, polypropylene), blown into thin film. It is the foundation of plastic bag production.
Type: according to production requirements, fan can be divided into single layer fan, double layer fan and triplelayer fan.
Bagging machine:
Function: This machine heats the sealing, will blow the membrane machine produces the membrane cut into the flat bag, vest bag, roller bag and so on various shapes.
Type: Bagging machine can be divided into hot cutting machine and hot cutting machine according to the shape of cloth bag.
Printing press:
Function: machine prints patterns or words on film to enhance the added value of plastic bags.
Type: gravure or flexographic printing machines is a common printing equipment, especially for short-run orders. Auxiliary equipment
Laminators:
Function: Laminate different materials to make heat-sealing heat-sealable packaging film, suitable for producing food, tea, snacks and other packaging bags.
Cutters:
Function: according to the needs of different bagging bag makers can be cut into a certain width of large roll film.
Scroll:
Function: Inverted printed film, convenient for later bagging.
Auxiliary Equipment
Cooling Equipment: ensures stable film formation during blowing.
Conveyor Equipment: automatic film transmission line.
Rewinding equipment: Collect finished film or plastic bags.
Test equipment: such as tension controllers and deviation detectors to ensure a steady flow of materials during production.
Waste recovery system: the collection and resource recycling of waste generated during bagging.
