食品包裝袋生產(chǎn)廠家的食品包裝袋的異味會導(dǎo)致食品風(fēng)味的變化，甚影響食品質(zhì)量，損害市民的健康。尤其是巧克力、奶粉、濰華餅干、薯片等對氣味要求特別的食品。食品包裝袋有異味的原因是什么?

The peculiar smell of food packaging bags of food packaging bag manufacturers will lead to changes in food flavor, even affect food quality, and damage the health of citizens. Especially chocolate, milk powder, Weihua biscuits, potato chips and other foods with special smell requirements. What is the reason for the peculiar smell in the food packaging bag?

1. 在印刷過程中，經(jīng)常使用各種溶劑對油墨進(jìn)行稀釋，從而提高油墨的印刷適應(yīng)性，提高油墨的加工強度，使印刷產(chǎn)品更加豐富、飽滿、生動。油墨轉(zhuǎn)移到各種薄膜上后，油墨中的溶劑會逐漸蒸發(fā);如果油墨表面的初級固化會阻礙內(nèi)部溶劑的有用蒸發(fā)，就說明溶劑會完全釋放出來，也就是我們的溶劑殘渣用過了，顯示出殘留的溶劑氣味，影響包裝材料。油墨干燥時間的長短與啟動速度有直接關(guān)系。

1. In the printing process, various solvents are often used to dilute the ink, so as to improve the printing adaptability of the ink, improve the processing strength of the ink, and make the printing products more rich, full and vivid. After the ink is transferred to various films, the solvent in the ink will gradually evaporate; If the primary curing of the ink surface will hinder the useful evaporation of the internal solvent, it means that the solvent will be completely released, that is, our solvent residue has been used, showing the residual solvent smell, which affects the packaging materials. The length of ink drying time is directly related to the starting speed.

2. 如果食品包裝袋的啟動速度超過正確的工藝要求，油墨就會在薄膜表面凝固，內(nèi)部溶劑也不會完全蒸發(fā)。特別是如果后一組顏色是較大的色塊，印刷工藝還應(yīng)根據(jù)印刷承印物選擇不同種類的油墨，同時使用不同種類的油墨和不同的溶劑。由于印刷圖片的多樣性，圖片可以由單色塊或多色塊組成。

2. If the starting speed of the food packaging bag exceeds the correct process requirements, the ink will solidify on the film surface and the internal solvent will not completely evaporate. Especially if the latter group of colors is a large color block, the printing process should also select different types of inks according to the printing substrate, and use different types of inks and different solvents at the same time. Due to the diversity of printed pictures, pictures can be composed of monochrome blocks or multi-color blocks.

3.食品包裝袋的速度和早期風(fēng)量。如果溫度不合適，會有各種溶劑殘留。而且，在干燥過程中，由于膠粘劑的用量不同，每3 ~ 6克的要求也不同，生產(chǎn)中膠粘劑的粘度也不同。如果工藝參數(shù)設(shè)置不合理，容易出現(xiàn)溶劑殘留過大的問題。

3. Speed and early air volume of food packaging bags. If the temperature is not appropriate, there will be various solvent residues. Moreover, in the drying process, due to the different amount of adhesive, the requirements of 3~6 grams per square meter are also different, and the viscosity of adhesive in production is also different. If the process parameters are set unreasonably, the problem of excessive solvent residue is likely to occur.
