Tapes Coating Machine
1. Moveable blade device.
2. Guiding roller in oven will synchronously rotates with main shaft.
3. Solenoid operated valve controlling is adopted for Anilx roller and drawing roller.
4. Automatic meter-measuring devices.
5. Key mode air shaft is used for unwinding and rewinding shafts, easy to load and unload.
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.

Coating operation process --
? Pre-adjust the gap gap
1. Adjust the gap between the back roller and the coating roller. The gap is generally the thickness of the two layers of aluminum foil and copper foil (note: the adjustment of the roll gap on both sides is basically the same). The actual adjustment of the roll gap can be adjusted to adjust the specific parameters in the pushing device. The program is automatically saved once, and no adjustment is needed next time.
