模切过程中离型纸的问题Release paper problem in the process of the die cutting

一、这种纸在贴的时候很好撕下来，但在一个周期(24小时)以后就难剥离，三个周期就拉不掉了。 这样的离型纸主要是不稳定，纸张密度不好、涂布不均匀、它的防渗透力差，所以在贴一个周期的时候，胶能渗透到离型纸里面，所以无法剥离!所以必须更换密度比较好的，纸张比较好的，涂硅均匀的，比较稳定的纸张做低纸。

Firstly, this kind of paper is good to tear off when sticking, but it is difficult to peel off after a cycle (24 hours), and three cycles can not be pulled off. This release paper is mainly unstable, paper density is not good, uneven coating, its permeability is poor, so when pasting a cycle, the glue can penetrate into the release paper, so it can not be peeled! So we must replace the density is better, the paper is better, coated with uniform silicon, more stable paper to do low paper.

二、进口双面胶的剥离不良，很多胶带都会有这个现象，因为进口的双面胶的物性都不一样，常规用的主要有3M、日东、索尼、积水、TESA等，有无基材的有基材的，很多厂商为了方便就用一种底纸来模切，所以导致剥离不良。所以必须判断好胶带的粘性，在胶带的粘性差比较大的情况下把底纸分开使用。

Secondly, the peeling of imported double-sided adhesive tape is bad, many tapes will have this phenomenon, because the physical properties of imported double-sided adhesive tape are not the same, the conventional use of 3M, Japan, SONY, water, TESA, there is no substrate with substrate, many manufacturers in order to facilitate the use of a base paper to die cutting, so lead to poor stripping. Therefore, it is necessary to judge the viscosity of the tape, and separate the base paper in the case of a large viscosity difference of the tape.

三、平时用来贴的这款胶带都可以，但是模切以后很难排废或者是因为产品太小不能剥离。这样的情况呢就要注意了，有的是排废过程中容易把产品带起，这说明剥离力太轻，可以选择稍重一点的试一下。如果是不能剥离或剥离不良这样的情况也很正常(特别是无基材的)，因为产品面积过小，在剥离力不够轻在剥离的时候就容易造成变形等现象，所以必须用更轻的离型纸。  因为现在有很多用户都反映有这种现象,其实离型纸不能完全靠刚开始的离型力来判断离型纸的本质,因为不同的涂布方式'不同的原纸都会有不同的离型力周期.还有就是离型纸的防渗透力,市场上还有一种格拉辛是用蜡硅油涂的,表面很漂亮,而且刚开始帖贴合的时候离型力很轻,但过几天后就撕不下来等现象,所以我建议用格拉辛最好还是用正品,不要用那些乱码的.3M9460的胶性比较粘,所以离型纸必须用涂布均匀,轻离型的离型纸,建议用无溶剂上硅的离型纸.  大家在选择离型材料的时候，要做三个周期的测试，更应该做15天的高温高湿测试。 只有通过了这样严格要求的离型纸，才是真正可靠的离型纸。

Thirdly, usually used to paste the tape can be, but it is difficult to discharge waste after die cutting or because the product is too small to peel. In this case, we should pay attention to the fact that some of the products are easy to take up in the waste discharge process, which shows that the stripping force is too light. You can choose to try a little heavier. If it is not peeling or peeling bad such a situation is also very normal (especially no substrate), because the product area is too small, in the peeling force is not light enough in the peeling when it is easy to cause deformation and other phenomena, so you must use lighter release paper. Because now a lot of users have reflected this phenomenon, in fact, the release paper can not completely rely on the beginning of the release force to judge the nature of the release paper, because different coating methods' different base paper will have different release force cycle. And from type paper anti seepage force, the market is also a gration is made of silicone oil wax coating, the surface is very beautiful, and just began to post fit mold force is very light, but after a few days can't tear down and wait for a phenomenon, so I suggest using gration would better use an authentic, don't use the gibberish.3M9460 comparison of glue stick, so the mold must be coated uniformly, For light release paper, it is recommended to use solvent-free silicon release paper. When choosing release material, three cycles of testing should be done, and 15 days of high temperature and high humidity test should be done. Only through such strict requirements of the release paper, is really reliable release paper.
