Compostable Flat Bottom Pouches | Biodegradable Kraft Solutions

Summary

摘要

From Ryan Wong's Engineering Notebook: A premium US brand noted, 'I'm looking to purchase flat bottom pouches in the biodegradable material. Stock kraft material, zipper, heat sealed, and no valve please.' We address this by balancing barrier needs, as thick foil is sometimes required for 700g sizes instead of metallized thin foil to avoid metal detector issues.

来自Ryan Wong的工程笔记：一个美国高端品牌指出：“我希望购买可生物降解材料的平底袋。请使用现货牛皮纸材料，带拉链，热封，无气阀。”我们通过平衡阻隔需求来解决这个问题，因为700g尺寸有时需要厚铝箔而不是金属化薄铝箔，以避免金属探测器问题。

工程細節

From Ryan Wong's Engineering Notebook: For compostable flat bottom pouches, replacing metalized films can be tricky for larger volumes (like 1KG or 700g). As one client case showed, 'we only can do thick foil instead of metalised thin foil. if order, they may have problem going through metal detector'. We must carefully select compostable barriers (like EVOH-free or PLA) that maintain shelf life without compromising the flat bottom rigidity.

来自Ryan Wong的工程笔记：对于可堆肥平底袋，在大容量（如1KG或700g）中替换金属化薄膜可能会很棘手。正如一个客户案例所示，“我们只能做厚铝箔而不是金属化薄铝箔。如果订购，它们可能会在通过金属探测器时遇到问题”。我们必须仔细选择可堆肥阻隔层（如无EVOH或PLA），在不影响平底挺度的情况下保持保质期。
