Description

一种环保袋材料及其制备方法
技术领域
本发明涉及造纸技术领域,具体涉及一种环保袋材料及其制备方法。
背景技术
随着科技技术的发展,新生出多种行业,使得人们的生活日益便捷。其中外卖就是其中一种新型行业,尽管该行业给人们的生活带来了极大的便捷,基本上做到足不出户吃大餐,或者在工作时间繁忙的时候能不需出门即可享受的各种美食或饮料。然而,伴随该行业的发展,随之产生了大量的垃圾。据统计,仅以美团、饿了么外卖的数据,每天订单量约为700万单,假设一单外卖只用1个塑料袋,而1个塑料袋为0.06平方米计算,总面积就达到42万平方米,足以覆盖59个足球场;而实际情况更加糟糕,往往一单外卖除了最少1个塑料袋外,还有2~4个餐盒,一次性筷子,塑料汤勺,这些材料回收价值不高且无法重复利用。
我国作为农业大国,水稻秸秆资源十分丰富,年产量达3亿吨,是巨大的可再生资源。随着科技技术发展,水稻秸秆作为劣质燃料被煤或电取代,作为肥料被化肥取代,因此逐步演变成无用的负担物而被就地焚烧,严重污染了生态环境。水稻秸秆主要秸秆成分是纤维素、半纤维素组成。
因此,将水稻秸秆与纸箱或纸板废纸制浆,以作为环保袋材料,不仅减轻水稻秸秆处理压力,同时能缓解因外卖行业带来的一次性塑料袋污染问题。
