目前，PVB中间膜的生产工艺主要有两种方式，一种是过辊法，一种是过水法。过辊法是采用两只辊或三只辊（有光辊，有花纹辊）流延的方式生产出胶片。过辊法投资低，技术相对成熟，设备也相对容易操作。过水法是普遍认为生产的胶片白度更好、花纹更均匀的一种工艺，它是采用水箱冷却定性而非辊筒，然后经过除水，测厚，烘箱，冷却，隔离膜复合、牵引，后收卷。因为过水法产品优点多于过辊法，被越来越多的厂家所采用。
风量、风刀的造型和设计。过多水分如果长时间滞留，对胶片质量也会产生影响，现在普遍采用刀，风刀数量已足够，关键在于风刀的设计、选择和位置。
因为过水法产品优点多于过辊法，被越来越多的厂家所采用。过水法生产过程中有以下几点需要特别注意：
水箱的设计。水箱的大小、数量也与生产线的速度产量有直接关系，保证水箱的温度均匀、水循环不引起波动，这是重中之重。
At present, there are two main methods for the production of PVB interlayer film, one is the over-roll method and the other is the water-pass method. The over-roll method is to produce a film by casting two rolls or three rolls (with a light roll and a pattern roll). The over-roll method has low investment, the technology is relatively mature, and the equipment is relatively easy to operate. The water-passing method is a process that is generally believed to produce a film with better whiteness and a more uniform pattern. It uses a water tank to cool the characterization instead of a roller, and then removes water, thickness, oven, cooling, separator composite, and traction. Finally, the volume is collected. Because the over-water method has more advantages than the over-roll method, it is used by more and more manufacturers. The following points in the production process of the water-passing method require special attention:
