On feed system of the main equipment to realize the specialist is responsible, in succession of observation, record the running situation, completes the registration and transfer, such as the central console parameter Settings, the operation of the vacuum station voice the dust and dust removal device processing, raw material conveying state whether smooth, compressed air is in the normal range, such as shape material phenomena.

Nowadays, dalian plastic film blowing machine develops high-end technology, blowing plastic film can also be used as food preservation and other application technology, the new film blowing machine manufacturing road. Blown film machine and the quality of the blown film technology determines the quality of the film forming, so a good performance of blown film machine in the process of production of thin film showed good ability to adapt the market, improve the production efficiency at the same time, provide convenience for the people and promote the harmonious development of society.

In the future, with the continuous development of science and technology, the plastic film blowing machine will play more and more roles and push the plastics and packaging industry to the high end. At present, in the development and production of high-end equipment, domestic film blowing machine has not reached the international level. Relying on the large consumer group, the market prospect is favored, but the high-end development is the development trend that the film blowing machine must face.

The expert points out that the composite materials are two or more materials, which are combined by one or more composite processes to form a composite material of certain functions. Generally, it can be divided into basic level, functional layer and hot seal layer. The grass roots are mainly beautiful, printing, and moisture resistance. The functional layer mainly blocks and avoids light, such as VMPET, AL, EVOH and PVDC, etc. The thermal sealing layer is in direct contact with the packaging material, and it has the functions of adaptability, permeability, good heat sealing, transparency and opening day.
