聚乙烯醇（PVA）和胶原蛋白水解产物（CH）的混合共混物，皮革工业的附加值废物，已通过吹塑挤出转化为环境可降解膜。将含有5-15% CH的吹塑挤出膜作为自适应地膜进行测试，并分析其环境降解倾向。PVA/CH复合膜在土壤中迅速崩解，具有一定的缓释作用，可作为移栽用膜。
Hybrid blends of poly(vinyl alcohol) (PVA) and collagen hydrolyzate (CH), an added value waste from leather indutry, have been converted by blown molding extrusion, to environmentally degradable films. Blown extruded films comprising 5-15% of CH, were tested as sel fertilizing mulching films and analyzed for their propensity to enviromental degradation. PVA/CH films rapidly disintegrate when buried in soil, and resulted promising for application such as transplanting films, with additional fertilizing action of CH.
