The Blowing Film Business Unit of GUANGDONG BAST EXTRUTECH CO., LTD was established in 2020, mainly engaged in the production line equipment of FFS heavy packaging bags, cold drawn stretch sleeve films, and heat shrink films. Compared with similar equipment, the 2500MM FIVE-LAYER POD BLOWN FILM EXTRUSION LINE independently developed and designed by BAST has advantages such as high yield, good product plasticity, and low energy consumption. It can effectively solve the shortcomings of existing technology and successfully achieve the use of more types of raw materials, which can be mixed and configured with multiple raw materials. Under this premise, it can not only meet the production requirements of diversified products for enterprises, but also achieve practical needs such as reducing the investment of precious raw materials and reducing the cost of per unit area film.

In addition, the opposition of multi-layer structures can increase the likelihood of improvement, and the high output of equipment demonstrates more significant advantages, greatly increasing the space for enterprises to improve efficiency and reduce costs.

The 2.5 meter five layer POD blown film production line is an intelligent production line equipment developed by our company through years of technological accumulation and the emergence of products in new fields. Its construction and installation require high precision and professionalism, requiring repeated debugging operations.

The construction steps of a 2.5 meter five layer POD blown film production line are as follows:

1. Assembly of each single machine: host, mold, air, foam stabilizer, horizontal rotation traction, idler roller frame, deviation correction, secondary traction, winding machine, heat exchange system, main control cabinet, etc

2. Construction of various platforms: the central platform on the second floor, the electric cabinet platform on the second floor, the deviation correction corona platform on the second floor, the third floor platform, and the fourth floor platform 3. Build from top to bottom:

A. Install the fourth floor platform and machines

B. Lift the fourth floor and install the third floor platform and machines

C. Lift the third floor, install the second floor platform and machines

D. Lift to the second floor, install the first floor host, mold, secondary traction, winding machine, etc.

E. Whole line assembly and installation of water and electrical circuitsWhole line assembly and installation of water and electrical circuits

F. Whole line winter machine debugging and start-up test.
