全台塑膠包裝使用量驚人，估計每年可製造34萬噸多層複合包裝，盡數丟棄焚化，造成大量碳排成一大難題。為因應全球減碳議題，塑膠包裝回收開發成為顯學，因此工研院材料與化工研究所針對無法回收之多層複合包裝進行單一材質化技術開發。
Taiwan's plastic packaging consumption is staggering, estimated at 340,000 tons of annual multi-layer composites. This massive waste through incineration leads to significant carbon emissions. Driven by global carbon reduction initiatives, recyclable plastic packaging has become a critical research focus. Consequently, ITRI is developing single-material packaging solutions to replace currently unrecyclable multi-layer composites.
材化所將包裝材料中佔比最高、回收性最佳的聚乙烯作為主材料，開發出延伸級聚乙烯薄膜專利技術取代既有保護層，並引入蒸鍍聚乙烯膜(VMPE)取代阻隔層使用的鋁箔，開發低碳高阻隔聚烯包裝袋。
MCL has developed a patented technology for extended-grade thin films utilizing widely used and recyclable polyethylene.
This technique incorporates vapor-deposited polyethylene film (VMPE) to replace aluminum foil in barrier layers, creating low-carbon, high-barrier polyolefin bags for unrecyclable packaging.
透過與彩藝廠合作量產開發，可成功將全聚乙烯包材製袋與設計
-
外觀：包裝彩色印刷美觀，可客製化外觀設計
-
保護：維持一定程度保存性(防潮、阻氣)，可熱封
-
回收：德國Interzero國際認證標準可回收
目前正積極推廣相關產品包裝，現已成功應用在咖啡濾掛袋外包裝(可回收4號LDPE)。
Product Features
Collaborating with Formosa Flexible Packaging Corp., we have successfully designed and manufactured mono-polyethylene (PE) packaging bags.
-
Appearance: The packaging features high-quality color printing with customizable design options.
-
Protection: Provides reliable protection with moisture and gas barrier properties; supports heat sealing.
-
Recyclability: Certified recyclable by Interzero, Germany (international standard).
We are actively promoting this sustainable packaging solution, which has already been successfully applied to the outer packaging of drip coffee bags (recyclable under LDPE #4 classification).
