来自皮革工业的水解胶原蛋白是一种天然聚合物，很容易以低成本获得，它的使用不与食品工业或其他主要应用相竞争，因为它是制革过程中的废物和副产品。在这项工作中，聚乙烯-胶原蛋白水解混合物的比例为100/0,90/10和80/20，使用配有单螺杆挤出机的吹膜生产线进行加工。吹膜是一种广泛用于生产大多数塑料薄膜和包装袋的成型技术。研究了工艺参数对吹膜物性的影响。通过力学测试、扫描电镜和热分析对挤压膜进行了表征。制备的薄膜表现出令人满意的机械和热性能，因此聚乙烯-胶原蛋白水解混合物似乎是生产创新材料的有希望的候选人，适用于生产热塑性产品，用于包装和农业领域。
Hydrolyzed collagen from leather industry is a natural polymer easily available at low cost and its use is not in competition with food industries or other main applications because it is a waste material and a by-product of the tanning process. In this work, polyethylene-collagen hydrolizate blends, at ratios of 100/0, 90/10 and 80/20, were processed using a blow film line equipped with a single screw extruder. Film blowing is a shaping technique used extensively to produce most plastics films and bags for packaging applications. The effect of processing parameters on the physical properties of blown films was investigated. The extruded films were characterized through mechanical testing, scanning electron microscopy, and thermal analysis. The manufactured films showed satisfactory mechanical and thermal properties, thus polyethylene-collagen hydrolizate blends appears as promising candidate for the production of innovative material suitable for production of thermoplastic items for applications in packaging and agricultural segments.
