Among them, PLA film-forming methods include film blowing, tape casting, on-line tape casting and static stretching.
Among them, PLA material is formed by film blowing process, and there are many kinds of film blowers in the market, including small film blowers (single-layer film blowers) and multi-layer film blowers (three or five layers). It is suggested to buy multilayer blown film, which can modify PLA materials and meet the current market demand-good tensile properties and flexibility.
POTOP Guangzhou's three-layer * * * extrusion film experimental machine can meet the experimental forming requirements of modified PLA film.
First of all, it is suitable for the research and development of new materials TPU, PVDF, PLA and thermoplastic biodegradable plastic PBAT, as well as the optimization of modified materials and formulas.
Secondly, the equipment has high precision and convenient operation. Automatic and accurate measurement of important signals, such as melt pressure and temperature during extrusion. The electrical components of extruder and screw barrel all adopt domestic and foreign famous brand products; The servo motor of each roller of the small film blowing machine is driven independently to realize the stable operation of each roller. The servo drive of the film blowing frame can adjust the height up and down, and the film blowing auxiliary machine integrates the functions of traction, trimming and winding.
POTOP Guangzhou was established in 2009, and it is Panyu Branch of National Engineering Research Center of New Polymer Molding Equipment of South China University of Technology. Professional technical consultation can be provided free of charge, and three-layer extrusion blow-molding film experimental equipment can be tailored for modified PLA film; Free on-site debugging, lifelong maintenance of equipment!
