SLV22 PVDC resin

mainly used for single-layer melt extrusion double-bubble processing processing, compared with SLV-20 PVDC resin, through technical improvement, can be processed into thinner thickness (single layer 10~12um) transparent film, suitable for processing PVDC plastic wrap products. Compared with traditional plastic wrap, it has superior barrier and freshness.
