通常,在瓦楞纸板包装箱内使用的缓冲材料绝大多数为聚苯乙烯泡沫,但随环境意识的增强,要求开发能够再利用的缓冲材料的呼声日渐增高。日本最大的瓦楞纸板厂家下属—公司开发了木质系泡沫材料。该材料是以锯屑和木材加工边角料等废弃木材和废纸为原料。其技术关键是在常压、较低温度、短时间内使木质材料液化。以往将 Often, the majority of cushioning materials used in corrugated cardboard containers are polystyrene foam, but increasing environmental awareness calls for the development of increasingly reusable cushioning materials. Japan’s largest subsidiary of corrugated cardboard manufacturers - the company developed a wood-based foam. The material is based on sawdust and wood processing scrap and other waste wood and waste paper as raw material. The key technology is in the atmospheric pressure, lower temperature, a short period of liquefaction of wood materials. Past will
