The concentration under reduced pressure brings short time of concentration and prevent the destruction of the effective content in the thermalsensitivematerial.
由于采用减压浓缩,故浓缩时间短,且不会破坏热敏性物料的有效成份。

The mechanical properties of such oriented PE were rather sensitive to the process temperature, and the thermal shrinkage of the material was also high.
Because raw material can be dried momentarily. Especially, it is suitable for drying thermalsensitive raw, materials. It can maintain color, smell and taste of raw materials.
