Specialty Film Blowing Machines
Two specialist lines from the SJ family: twin-screw PP film machines for stiff packaging film, and 3-layer air bubble machines for protective cushioning film.
Definition
What are specialty film blowing machines?
Specialty film lines handle resins and structures beyond standard PE film. A twin-screw PP line melts PP at lower shear for stiff, glossy film used in garment and textile bags. An air bubble film line extrudes three layers — bubble, base and coating — to trap air pockets for protective packaging.
