Non-fluorinated greaseproof paper manufacturing method
本發明係一種非氟素防油紙及其製造方法,特別是塗布天然聚合物及/或合成聚合物之混合物於紙張上所製成之防油紙。
The present invention relates to a non-fluorine greaseproof paper and a method for producing the same, and more particularly to a greaseproof paper prepared by coating a mixture of a natural polymer and/or a synthetic polymer on paper.
防油隔離(grease barrier)包裝容器在紙與紙板及紙模領域的主要應用有:1)紙模:紙盤、湯碗、便當盒、速食容器;2)裱面紙板:比薩餅、肉類、肥皂、零配件、繩子;3)摺式紙盒:點心、外帶速食、糕餅粉、清潔劑、清新劑;4)多層袋:點心、糕餅粉、寵物食物、木炭;5)軟式包裝:速食、糖果、巧克力、人造奶油、奶油、烘焙食物、寵物食物、肥皂;6)特殊紙:非碳複寫紙、標籤紙、裝飾紙、藝術紙等六大方面。
The main applications of the grease barrier packaging container in the field of paper and cardboard and paper mold are: 1) paper mold: paper tray, soup bowl, lunch box, instant food container; 2) kneading cardboard: pizza, meat, Soap, spare parts, rope; 3) folding tray: snacks, takeaway fast food, cake powder, detergent, freshener; 4) multi-layer bags: snacks, cake powder, pet food, charcoal; 5) soft packaging: speed Food, candy, chocolate, margarine, cream, baked goods, pet food, soap; 6) special paper: non-carbon carbon paper, label paper, decorative paper, art paper and other six aspects.
防油隔離可藉由:1)多種聚烯烴類(polyolefins,例如:PE、PP等)貼合;2)塗布氟素化合物(florochemicals);3)熱蠟處理;4)噴鋁貼合等四種方式來達成,其中以前兩種方式為目前市面上的主流。近年來,氟素化合物逐漸被廣泛使用,不僅因其成膜的可撓性、疏水及撥油的雙效功能;最重要的是,與聚烯烴類貼合方式比較,具有相當低成本競爭優勢。
Oil-proof isolation can be achieved by: 1) bonding a variety of polyolefins (for example, PE, PP, etc.); 2) coating fluorine compounds (florochemicals); 3) hot wax treatment; 4) spraying aluminum bonding, etc. The way to achieve, the former two ways are currently the mainstream on the market. In recent years, fluorinated compounds have been widely used, not only because of their flexibility, hydrophobicity, and oil-repellent double-effect function; and most importantly, they have a relatively low-cost competitive advantage compared with polyolefin-based bonding methods. .
目前中華民國專利號,I266797、591055及506979等,據以完全揭露氟素化合物應用於防油紙之方法及功效,然而,氟素化合物於製造過程中所產生的有毒中間產物將影響生態環境;亦有文獻
指出,含氟素化合物產品經高溫加熱後釋放出的有毒物質,可經由食物進入人體,造成身體機能產生病變,大幅提高致癌風險;因此,開發非氟素防油劑實為當務之急。
At present, the Republic of China patent number, I266797, 591055 and 506979, etc., according to the method and effect of the application of fluorocarbon compounds in greaseproof paper, however, the toxic intermediates produced by the fluorocarbon compounds in the manufacturing process will affect the ecological environment; Literature
It is pointed out that the toxic substances released by the fluorinated compound products after being heated at a high temperature can enter the human body through food, causing pathological changes in the body functions and greatly increasing the risk of cancer; therefore, the development of non-fluorine oil-repellent agents is a top priority.
