Benchtop Small Lab Film Blowing Machine

Benchtop small lab film blowing machine The benchtop small film blowing machine structure is compact, simple operation, can be used for single and multi-layer blown film, can be applicable to all polymerdispersion research. Benchtop film blowing machine consisted ofa small single screw extruder and small film blowing tower. It is the best choicefor quality control and testing the color distribution. Parameters: 1.
