Down-blowing water-cooling blown film machine: Circulating water is used to cool the molten plastic extruded from the die head, so that the film can be quickly shaped.

Air-cooling blown film machine: The blower blows cold air to the film bubble to cool and shape the film. The cold air is transported to the surface of the film bubble by the air ring, air duct and other components.

Down-blowing water-cooling blown film machine: It can make the film reach high transparency. And the film has better barrier and heat sealing properties. The surface flatness is high and the wrinkles and distortions are less. Down-blown water-cooled blown film machine is suitable for high-end packaging film.

Air-cooling blown film machine: If the air ring and blower work well together, it can also produce film with uniform thickness and smooth surface. However, in terms of transparency, it is usually slightly inferior to water-cooled film blowing machines.

Down-blowing water-cooling blown film machine: The production process is relatively complex. It needs professional technicians to operate. In addition,the existence of water cooling system makes the equipment start and stop relatively slow. The production speed of blown film machine is limited. Down-Blowing water-cooling blown film machine is not suitable for large-scale rapid production.

Air-cooling blown film machine: The structure is relatively simple.It is easy to operate. It starts and stops quickly. Higher production efficiency. The production efficiency is high. Air-cooling blown film machine can meet the production needs of large output.

Down-blowing water-cooling blown film machine: Since it is equipped with a water-cooling circulation system, the initial investment cost of the equipment is relatively high. It is also necessary to regularly maintain and replace water cooling equipment and filters and other components. The maintenance cost is also high.

Air-cooling blown film machine:The equipment has a simple structure and does not require a water cooling system. The initial investment cost is low. And the maintenance is economical and simple. The maintenance cost is about half of that of the water-cooled type.

Down-blowing water-cooling blown film machine: The water-cooling circulation system has high energy consumption. It is not conducive to energy saving and consumption reduction. In addition, the water used in the production process may contain chemical components. There are certain environmental pollution problems.

Air-cooling blown film machine: It uses air cooling, which does not require a lot of water. It saves water resources. There is no water pollution problem. The energy consumption is relatively low. It is more energy-saving and environmentally friendly.

Down-blowing water-cooling blown film machine: It is suitable for occasions with high requirements on film transparency, barrier property and heat sealing property. Such as food, medicine, cosmetics and other high-end packaging. As well as some special applications that require high precision film.

Air-cooling blown film machine: It is widely used in the production of various plastic films.Such as agricultural covering films, industrial packaging films, ordinary plastic bags, etc. Air-cooled film blowing machines can meet the production requirements where film quality is not extremely high.
