过去十年中,由于世界上纤维薄膜用户的减少和定向聚丙烯(OPP)用户的大量增加,两种产品的替代明显有利于 OPP。这种发展,对我们这种同时生产两种产品的厂商来说,造成很多困难。一种产品的成功也就意味着另一种产品的失败。从长远的观点出发不断改善这个替代过程是较为明智的解决方法。 Over the past decade, the substitution of two products has clearly contributed to OPP due to the reduction of fiber membrane users in the world and the substantial increase in users of oriented polypropylene (OPP). This development has caused a lot of difficulties for us, a manufacturer that produces both products at the same time. The success of a product also means the failure of another product. From a long-term perspective, it is a more sensible solution to continuously improve this alternative process.
