Abstract
This invention relates to a polyvinyl chloride sheet comprising crosslinked thin layer(s) and uncrosslinked layer(s), at least one surface of the sheet being a crosslinked layer. The thickness of the said crosslinked layer ranges between about 0.05 to about 2 microns, and the degree of the chlorination of the said layer is not greater than about 45% of that of the uncrosslinked layer, and the degree of heat shrinkage is not greater than about 1%. This sheet provides many advantages for blood bags and infusion bags.
