Model ABA is equipped with two extruders to supply A+B+A die. ABA-TD series is equipped with standard screws to provide two dies. ABA-FD series is equipped with forced feeding screws to provide two dies in order to have more capacity.
The ABA structure can be used HDPE in out-layer, and added carbonate & recycled resin in in-layer. The film will get the similar stretch & touch feeling of HDPE single layer film. The physical structure of HDPE single layer bags will be destroyed because of adding carbonate & recycled resin, but ABA bags will be totally improved in physical structure and save resin cost.
Purchasing extra 2-layer co-extrusion die can produce normal A+B 2-layer film.
