紙餐盒如何達到防水防油效果
來源:www.mingmingda.com 發(fā)布時間:2023-02-22 瀏覽次數(shù):122
紙餐盒的應用范圍十分的廣泛,我們在使用之前肯定是需要知道它的特性的,這樣才可以更好的去應用它。那么一次性紙餐盒如何達到防水防油效果?其實這也是大家都在咨詢的問題。
The paper lunch box has a wide range of applications. We must know its characteristics before using it, so that we can better use it. So how can disposable paper lunch boxes achieve waterproof and oil-proof effect? In fact, this is also the question that everyone is asking.
它的答案是紙餐盒會添加一定食品級助劑,那么它一般防水劑1.0%-2.5%,防油劑0.5%-0.8%,這樣的話才可以達到防水防油的效果。并且它的測試一般是100℃的水,120℃的油,測試時間為30分鐘;特殊要求可做把油溫和測試時間延長。
The answer is that the paper lunch box will be added with certain food-grade additives, so it generally has a waterproof agent of 1.0% - 2.5% and an oil resistant agent of 0.5% - 0.8%, which can achieve the effect of water and oil resistance. And its test is generally 100 ℃ water, 120 ℃ oil, and the test time is 30 minutes; For special requirements, the oil temperature test time can be extended.
紙餐盒有兩種主要解決方案。一種方法是在紙張表面涂上連續(xù)且致密的有機高分子膜(涂層)。涂層材料包括聚丙烯酸酯、聚乙烯、聚乙烯醇、羧甲基纖維素等。涂有防油膜的紙質(zhì)餐具的安全風險在于涂布材料。聚合物膜本身不耐油,油脂還是可以在涂膜表面鋪展。
There are two main solutions for paper lunch boxes. One method is to coat the paper surface with continuous and dense organic polymer film (coating). Coating materials include polyacrylate, polyethylene, polyvinyl alcohol, carboxymethyl cellulose, etc. The safety risk of paper tableware coated with anti-oil film lies in the coating material. The polymer film itself is not oil-resistant, and grease can still be spread on the surface of the film.

另一種方法是修改紙纖維的表面,即在紙表面涂上一層水和防油劑。其中一些含有雙酚a油脂,當它們接觸高溫食品時可能會釋放有害物質(zhì),這種合成高分子材料在自然界中不能降解,存在環(huán)境污染問題。因此,對于具有防水防油劑的紙質(zhì)餐具,應注意防水防油劑的安全和環(huán)保。
Another method is to modify the surface of the paper fiber, that is, apply a layer of water and oil repellent on the paper surface. Some of them contain bisphenol a grease, which may release harmful substances when they contact with high-temperature food. This synthetic polymer material cannot be degraded in nature, and has environmental pollution problems. Therefore, for paper tableware with waterproof and oil repellent, attention should be paid to the safety and environmental protection of waterproof and oil repellent.
目前,含氟防水防油劑已在發(fā)達國家得到廣泛應用。通過漿內(nèi)添加、表面施膠或涂層處理,使紙張具有防水和防油的特性。其原理是利用氟材料的特殊表面性能來實現(xiàn)防水防油功能。氟碳化合物處理不僅可以獲得良好的防水性和耐油性,還可以保持原有的透氣性、柔軟性、強度、顏色和印刷性能。
At present, fluorine-containing water and oil repellents have been widely used in developed countries. The paper has the characteristics of water and oil resistance through the addition of pulp, surface sizing or coating treatment. Its principle is to use the special surface properties of fluorine materials to achieve the waterproof and oil-proof function. Fluorocarbon treatment can not only obtain good water and oil resistance, but also maintain the original permeability, softness, strength, color and printing performance.
