          不干膠貼紙加工出現電暈效果差、膠水回流是為什么?

            不干膠貼紙的應用,普遍應用在超市,或者是一些甜品店,奶茶店,或者是小食店之類的,關于商品標簽,重要信息之類,注意事項,用法之類的,或者是價格標注,都是利用不干膠貼紙啦,方便,而且快速,是這些不干膠貼紙成本低。
            Application of stickers, widely used in the supermarket, or are some sweet shop, milk tea shop, or a restaurant, such as about labels, important information, such as attention, such as usage, or is the price, all is the use of stickers, convenient, and fast, the focus is on the low cost of these stickers.

            不干膠標簽“飛標”的原因都在這里!膠水回流導致模切不斷,對于許多熱熔膠或者加厚涂膠的不干膠材料,在模切過程中膠水在被刀具切穿后非常容易回流重新粘連在一起,導致很嚴重的膠水拉絲現象從而造成模切過程中標簽被排廢邊帶起的現象。遇到這種問題,可以采取適當降低模切加工溫度的方式來減少膠水的回流。同時必須保持模切刀具的鋒利,以便能夠讓刀具瞬間切穿膠水層減少膠水的回流。如果是連機模切加工也可以采用適當提高印刷速度的方式來減少膠水的回流。
            Sticker label "fly mark" the reason is here! Backflow of glue leads to continuous die-cutting, for many hot melt glue or thickened adhesive adhesive material, in the die-cutting process after the glue is cut through the tool is very easy to backflow and re-adhesion together, resulting in very serious glue wire-drawing phenomenon, resulting in the die-cutting process of the label is discarded side belt phenomenon. Meet this kind of problem, can take the proper way to reduce the die cutting temperature to reduce the glue backflow. At the same time must keep the die-cutting tool sharp, in order to be able to cut through the glue layer to reduce the flow of glue. If it is even machine cutting processing can also be used to increase the printing speed of the appropriate way to reduce the backflow of glue.
            電暈效果差:薄膜材料掉墨與材料的表面能有關,表面能越強,油墨附著越牢固,反之亦然。但電暈效果會隨著時間而衰減,印刷時就有可能導致掉墨。這類現象多見于價格便宜的BOPP和PE材料,考慮到高涂層成本,多數廠家會對其進行電暈處理。遇到此種情況,應由廠家或供應商在印前重新進行電暈。
            Corona effect is poor: film material ink and material surface energy, the stronger the surface energy, ink adhesion is more firm, and vice versa. However, the corona effect will fade over time, which may lead to ink loss during printing. This kind of phenomenon sees the BOPP that the price is cheap and PE material more, consider high coating cost, most manufacturer can undertake corona processing to its. In this case, the manufacturer or supplier should re-corona before printing.
