匀称性对于机用缠绕膜有什么影响?

发布时间:2022-07-19 07:18:04 浏览:583
机用缠绕膜具有维修功能的一个前提条件是匀称性,卷绕膜的特性一方面取决于原材料的选择,另一方面则取决于膜的薄厚度,一般薄厚越大,缠绕膜的特性越高,缠绕膜的特性就越高,缠绕膜的特性已经保持稳定,不容易随厚度的提高而增加。
A prerequisite for the maintenance function of machine winding film is symmetry. The characteristics of winding film depend on the choice of raw materials on the one hand, and on the other hand on the thin thickness of the film. Generally, the greater the thickness, the higher the characteristics of winding film, the higher the characteristics of winding film. The characteristics of winding film have remained stable, and it is not easy to increase with the increase of thickness.
较薄、较高的原材料价格会较高,从而使卷绕的总成本急剧上升,使用多层高层复合缠绕膜可有效降低包装成本,但薄厚的操纵难度系数很大。
The price of thinner and higher raw materials will be higher, resulting in a sharp rise in the total cost of winding. The use of multi-layer high-rise composite winding film can effectively reduce the packaging cost, but the handling difficulty coefficient of thin and thick is very large.
如果薄层厚度不够均匀,容易出现作用薄弱环节,造成机用缠绕膜整体性能不稳定,将会出现部分周转材料特性较弱,导致商品达不上需要有的有效期,而且对部分缠绕膜(分外性能)的性能也会受到一定影响,从而影响到产品的性能。
If the thickness of the thin layer is not uniform, it is easy to have weak links, resulting in the instability of the overall performance of the machine winding film. Some revolving materials will have weak characteristics, resulting in the goods not reaching the required expiry date, and the performance of some winding films (extra performance) will also be affected to a certain extent, thus affecting the performance of the products.
机用缠绕膜厚匀称是否也会给缠绕膜包装印刷及其相关应用的工艺流程难以提升。例如,包装印刷在市场上常见的凹版印刷机,对包装印刷支撑力的控制是保证宣传品质量的关键,支撑力的操纵与卷材、薄板、薄层厚度的匀称性常有关联,操纵不太好能立即造成原材料的套印。此外,缠绕膜的薄壁匀称能力差,也会导致卷绕膜包装印刷后出现收卷偏位的情况。
Whether the uniform thickness of machine winding film will also make it difficult to improve the process flow of winding film packaging and printing and its related applications. For example, in the gravure printing machine commonly used in the market for packaging printing, the control of the supporting force of packaging printing is the key to ensure the quality of publicity materials. The control of the supporting force is often related to the symmetry of the thickness of coiled materials, thin sheets and thin layers. Poor control can immediately cause overprint of raw materials. In addition, the thin-wall symmetry of the winding film is poor, which will also lead to the winding deviation after the packaging and printing of the winding film.
高密度复合薄膜在制做全过程中,任意一层缠绕膜的薄厚不均匀都是造成事后生产加工的不均匀性,导致缠绕膜薄厚匀称性差。该产品适用于外包装,厚度不均匀的机用缠绕膜,作外包箱使用时,周转材料容易出现物理性能薄弱环节,假如在包装、运输、贮藏、市场销售全过程中,周转材料遭受很大的外力冲击,这种薄弱环节易出现裂缝、孔眼等导致原材料的储存作用下降或立即丧失。
In the whole process of making high-density composite film, the uneven thickness of any layer of winding film is caused by the uneven production and processing after the event, resulting in the poor uniformity of the thickness of winding film. This product is suitable for outer packaging. When the machine winding film with uneven thickness is used as an outsourcing box, the reusable materials are prone to weak links in physical properties. If the reusable materials are impacted by great external forces in the whole process of packaging, transportation, storage and marketing, such weak links are prone to cracks, holes, etc., which will lead to the decline or immediate loss of the storage function of raw materials.
