A Q:Why you can't make the cup to 168mm height?
A:Due to the material differentce, it is wheat fiber ,no PE coted inside.
Paper cup with PE to prevent liquid from leaking out or soaking through the paper.
but the wheat fiber inside don't have the PE coted (we will add oil repellent), if the cup is too high, can't unable to form cup.
为什么不能做168mm的秸秆杯子?
因为材料不同,秸秆杯子里面没有PE淋膜,纸杯有PE涂层防止漏水,弄湿纸张,但是秸秆材料没有这个涂层(我们会添加防油剂来防水),如果杯子高度太高,无法成型。
