Flex PVC clear is most desired, next is white, and the third best is colors or mixed colors.  Ideally the scrap would be in pellets or regrind but rolls are acceptable.  The plasticizer loading can be between 20-70 PHR.  The PVC must be clean with not dirt, tape or printing.   Since the shipment will originate outside North America, the gaylords or bundles should be able to be handled with a standard fork truck and will be shipped in 40 foot containers.
