Multiple functions and classifications of film blowing machine
Single-layer blown film machine:
Product introduction: Single-layer blown film machine is the most basic blown film equipment, which is suitable for the production of single-material plastic film. It extrudes the molten plastic resin into a tubular film through an extruder, which is then cooled and shaped by an air ring and finally rolled into a roll.
Applicable materials: suitable for the production of PE (polyethylene), PP (polypropylene) and other mono-material films.
Applications: Mainly used for the production of simple packaging bags, garbage bags, agricultural mulch films, etc.
Limitations: Only a single layer structure can be produced for film, and multi-layer lamination cannot be realized.
ABA Film Blowing Machine;
It is possible to extrude 3 layers of film of different materials at the same time on the same equipment, where layer A and layer B can be different materials or different formulations of the same material. This structure allows for functional differentiation between the surface and the core, for example, the top layer provides good printability or UV resistance, while the core layer provides strength or other special properties.
Applicable materials: suitable for the production of PE, EVA, EAA and other materials of composite films.
Applications: Widely used in food packaging, industrial packaging and other fields, especially in the need for special functions.
Flexibility: The proportions and materials of each layer can be adjusted according to the needs to meet different application requirements.
ABC three-layer co-extrusion blown film machine:
Three completely different layers of material can be extruded simultaneously on the same machine, and each layer can be independently selected for a different material or formulation. This structure enables more complex combinations of properties, such as high barrier, high strength, good printability, etc.
Applicable materials: suitable for the production of PE, PP, EVOH, PA (Nylon), PVDC and other materials of composite films.
Applications: Especially suitable for high-end packaging markets, such as food cling film, electronic component packaging, etc., as well as applications with strict performance requirements.
Complex process: Due to the co-extrusion of multiple materials, the equipment and technical requirements are high, but the added value of the product can be significantly increased.
