Polyethylene (PE) film--

 

Medium Density Polyethylene (MDPE):
-- Its density is between 0.93 and 0.94 g/cm2 between high density and low density polyethylene.

High density polyethylene (HDPE):
- The density is between 0.94 and 0.965 g/cm2. The high-density polyethylene film has better heat resistance and mechanical strength than the low-density polyethylene film, and has a small tensile elongation, and the film thickness is generally 0.03 mm or more, but the transparency is poor. It is printed on the front side and is mainly used as a vest bag, a garbage bag and a liner bag.

Crosslinked polyethylene (CLPE):
- Because it has higher heat resistance, tensile strength, heat shrinkage and barrier properties than other polyethylene products, its use is further expanded, and it is currently mostly used as a heat shrinkable packaging film.
In general, as the density increases, the mechanical properties and barrier properties will increase accordingly, and heat and heat will be good. Polyethylenes of the same density have different properties due to the different film forming processes. This is because the rotting method can be rapidly cooled, the crystallinity is low, the transparency is high, the turbidity is small, but the molecular arrangement is more irregular, so the barrier property is small, that is, the transmittance is large, the elongation is low, and the tear resistance is Poor cracking.

Note on the use of the coater:

1.3 shutdown procedure
1) Confirm that the coated pole piece has been wound up and then stop.
2) Turn off the heater power of the equipment and stop the drying fan and other fans when the temperature of each section drops below 60 degrees Celsius;
3) Stop the compressed air.
4) Disconnect power from the correcting cabinet and control cabinet.
1.4 Notes
1) Operators must undergo pre-job training and pass the assessment before they can be employed, and should strictly abide by these operating procedures.
2) Except for the necessary maintenance personnel, it is strictly forbidden for non-personnel personnel to operate the equipment or change the setting parameters.
3) The roller speed ratio is recommended to be set within the range of 1.3 to 1.5.
4) It must be confirmed that the air heater has not been activated until the drying fan has been started.
