Cast film has excellent heat sealing performance and transparency. It is one of the main packaging composite substrates. It is used to produce high temperature cooking film and vacuum aluminium coating. The market is very promising. Moreover, with the development of domestic casting film production equipment, some of the technical indicators have reached the international advanced level. As a result, the threshold to enter casting film production is getting lower and lower. For this reason, in order to be in place one step, some enterprises are competing to import casting film production lines. The higher the grade, the better the quality. This practice will cause huge waste of resources by throwing aside the market demand and return on investment.

1) The domestic tape casting film production line can be divided into 2500mm, 3000mm, 3500mm and 5000mm according to the film width. The configuration of extruder can be divided into three layers, five layers and seven layers.

2) The domestic tape casting film production line is mainly composed of five parts: extrusion part, tape casting part, corona part, winding part and electronic control part. Among them, the die and extrusion parts can be freely combined according to the requirements of customers, so as to meet the different needs of the vast majority of customers (market).

In addition, the design of domestic equipment also follows the international advanced level, such as:

A, unique design of the back device, can freely adjust the pressure of the extruder.

B, unique screw channel design, can be applied to different materials, to achieve a multi-purpose machine.

C, roller runner design, better cooling effect, more stable product quality, higher output.

D. The linear velocity of domestic tape casting film production line has reached the level of 160 m/min-250 m/min.

4) Compared with imported equipment, domestic tape casting film production line also has the characteristics of high speed, stable performance, environmental protection and energy saving. The thickness of the product is 0.017mm-0.08mm (the international standard is 0.025mm).
