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，將全聚乙烯包裝袋成功製袋並與製作成咖啡濾掛袋外包裝。
