I've seen a couple different methods for installing perforated film on Windows, and I don't think there is any one perfect way to do it.

我见过好几种不同的安装玻璃贴膜的方法，且我认为每一种方法都不是最完美的。

Perforated window film is not intended to be heated and formed like premium wrap vinyl so any heating and forming will end up lifting and shrinking quickly because of the memory in perforated film.

穿孔玻璃贴膜无需像优质乙烯基贴膜一样，要经过加热成型过程，因此任何加热成型都会很快地卷曲缩水。

If we're installing perforated film on a horizontal storefront window or rear vehicle window, where the width of the window makes it cumbersome to do a top down installation, we change it up a little.

如果我们要在水平的门店窗户或车辆窗户上贴膜，窗户的宽度会使得自顶向下的安装变得难以处理，所以我们要稍微改变一下策略。
