The film made by a hair dryer can be widely used for light and heavy packaging due to its good barrier properties, freshness, moisture resistance, frost resistance, oxygen resistance, and oil resistance. Such as all kinds of fresh fruits, meat food, Pickled vegetables, fresh milk, liquid drinks, medical supplies and other categories are widely used. But it's not made from garbage plastic, it's made from plastic pellets. Assembly is used for blowing plastic films such as low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE).

The three-layer co extrusion thin film production line adopts advanced technologies such as a new high-efficiency and low-energy consumption extrusion unit, IBC film bubble internal cooling system, ± 360 ° horizontal upward traction rotation system, photoelectric automatic correction device, fully automatic winding and film tension control, and computer screen automatic control system.

Shutdown method for three-layer co extrusion blown film machine

1. Turn off the start and then reduce the speed of the inner, outer, and middle main motors to zero.

2. Turn off the fan speed, traction speed, rotating die head, and rewinding button to return to zero.

3. Turn off the heating of zones 1, 2, 3, 4, and 5 of the extruder, and heat zones 1, 2, and 3 of the die body.

4. Turn off the main power and air pump switch.

5. Open the rubber roller to prevent its denaturation and damage.

6. Change the network.

7. After completion, clean the workshop debris and clean up the hygiene.

Compared with similar equipment, it has the advantages of higher output, better product plasticization, low energy consumption, and simple operation, completely solving problems such as film ruffles and winding heads, and taking product quality to a new level. The produced film has high transparency, puncture resistance, high toughness, good low-temperature heat cutting performance, good composite fastness, and anti curling properties!

In fact, many plastic blow molding machines malfunction due to improper operation. When we purchase equipment, there will be a dedicated person to tell us how to operate it, and of course, there are corresponding instructions for use. By having a dedicated person perform the operation, this training can also avoid unnecessary damage and extend its service life.
