    可堆肥淋膜树脂(纸与纸板)

    可堆肥淋膜树脂(纸与纸板) – Food-contact packaging materials product from Bio Green Foods

    关于此产品

    本品为可堆肥淋膜树脂,以粒料改性料形式供应,用于在纸和纸板上挤出淋膜及复合。纸质食品包装几乎从来不是纯纸:其表面带有一层薄薄的聚合物涂层,用以抗油脂和防潮,而本树脂正是通常用于此的聚乙烯(PE)的可堆肥替代品。本品为改性共混料而非单一树脂,因此没有单一 CAS 号,并在寿命终结时可堆肥。

    淋膜层正是淋膜纸包装难以处置的根源。聚乙烯(PE)既是纸杯留住液体、纸板挡住油脂的原因,也是淋膜纸杯和纸板难以再制浆、并被堆肥处理拒收的原因:制浆厂要的是纤维,却很难把纤维从膜层中分离出来;堆肥处理方看到的则是一层不会降解的塑料。这种结构的包装夹在纸与塑料两条回收路线之间,实际上两边都不接收。改用本树脂淋膜后,纸板可以连同涂层整体堆肥,纤维与涂层一起处理,这给了包装一条真正走得通的处置路线,而不是一句关于其中某一组分的宣称。涂层仍须完成原有的功能,而这既取决于厚度,更取决于连续性:抗油脂和防潮性能来自不间断的涂层,因此折痕或压线处的薄弱点就是渗漏通道,不论平均涂布量是多少。因此,涂布量以及由此获得的抗油脂和防潮阻隔性能,应针对具体包装及其内容物确定,因为干燥的烘焙包装纸与盛装内容物的纸盒对涂层的要求并不相同。本品以原料形式供应,供买方在自有产线上加工。我们不生产成品。

    主要用于淋膜纸杯、食品纸板与纸盒、抗油脂包装纸和可堆肥包装项目。

    Bio Green Foods 按涂布量、基材、生产线速度,以及包装及其内容物所需的抗油脂和防潮阻隔性能等规格供应该可堆肥淋膜树脂。
