手提袋覆膜
Handbag Film Covering
覆膜又称印后过塑、印后裱胶或印后贴膜，是指在印品的表面覆盖一层0.012～0.020㎜厚的透明塑料薄膜而形成一种纸塑合一的印后整饰工艺，一般分为预涂和即涂两种工艺。根据使用薄膜材料的不同又有高光膜和亚光膜之分。随着环保水性溶剂的使用，覆膜工艺的环保性有了进一步的提高。非牛皮纸袋多采用覆膜工艺，主要是因为覆膜可以增加色彩的浓度，产品防水避污性能好，纸张的抗老化、抗撕裂、抗戳穿等物理性能普遍提高，进而纸袋的牢度和强度改善，承载力明显增强。尤其是使用亚光膜能给人以柔和、感觉。
Coating, also known as post-press over-plastics, post-press gluing or post-press pasting, refers to the formation of a paper-plastic integration process by covering a layer ofthick transparent plastic film on the surface of a printed product, which is generally divided into pre-coating and post-printing finishing processes. According to the different materials used, there are high-light film and sub-light film. With the use of environmentally friendly water-borne solvents, the environmental protection of the film coating process has been further improved. Non-kraft paper bags mostly adopt Film-covering technology, mainly because Film-covering can increase the concentration of color, the product has good waterproof and pollution-proof performance, the physical properties of paper such as aging resistance, tearing resistance and puncture resistance are generally improved, and then the fastness and strength of paper bags are improved, and the carrying capacity is obviously enhanced. In particular, the use of matte film can give people a soft, feeling.
手提纸袋的覆膜工艺要注意几点：选择合适的覆膜胶水，尤其是满版金属墨产品和需要后续凹凸加工的情形;控制覆膜的速度并根据车速选择合适的施胶量;需覆膜的产品须待印后干透才能进行覆合作业，刚覆膜的产品也需放置一段时间再进行轧切、凹凸加工;印刷时喷粉过大还须进行覆膜前的除粉操作;加强对膜的电晕效果的检查等。如果不注意以上几点的控制，容易造成覆膜产品的脱膜、起泡、麻点等品质事故，甚至会导致批量报废。
Several points should be paid attention to in the process of covering handheld paper bags: 1) selecting suitable glue, especially full-plate metal ink products and following concave-convex processing; 2) controlling the speed of coating and choosing suitable sizing amount according to the speed of vehicle; 3) the products that need to be covered must be dry after printing before they can be covered, and the products that have just been covered need to be placed for a period of time before rolling, cutting and concave-convex processing; (4) Dedusting operation before coating should be carried out when spraying too much powder during printing; _Strengthen the examination of corona effect of film, etc. If we do not pay attention to the above control points, it is easy to cause quality accidents such as defilm, blistering, pitting, and even lead to mass scrap.
