Synergistic biopolymer blown film extrusion system and method |
摘要 |
A biopolymer blown film extrusion system comprising an extruder receiving polymer pellets and at least two additives, and generating a molten mass having at least one layer; a die receiving the molten extrudates and generating a bubble having at least one layer from a die orifice; an internal bubble blower operably connected to maintain air inside the bubble; a bubble collapsing frame receiving the bubble and generating a biopolymer film having at least one layer, the film having a selected elongation at break of 180% or more in one direction and heat sealing at 195° F. or less; a nip roller operably connected to draw the biopolymer film from the bubble collapsing frame; a turning bar operably connected to change a travel angle of the biopolymer film; and a travel roller operably connected to direct travel of the biopolymer film. |
