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

2. Adjust the gap between the coating roller and the knife roller. The general gap is between 300 and 400 microns. The specific adjustment is to adjust the clearance by turning the screw (the rotating screw is to rotate both sides at the same time)
? Apply PET film and set the coating width (Note: PET film must be firmly bonded with transparent tape, the coating width is based on the outlet of the slurry)
? Fix the waste pallet, the retaining plate, and carry out the trial coating (single-sided first inspection: whether the coating is dried, whether the coating width is correct, the width of the tabs on both sides, and the areal density)
? Formal coating (provided that all parameters and dimensions are correct), inspection ? Double-sided first inspection (including symmetry, double-sided density, etc.)
? When applying the other side, the strap must be firm (with aluminum foil tape), stop coating, stop heating, remove the coated aluminum copper foil, put it into the oven and heat it in vacuum.
? Turn off the machine, turn off the power, air supply, and clean the equipment.
? Put used tools in place and clean them off work.
