  • I will design a moisture-proof packaging.
  • Answer 1| 3091g 2| 562g
  • packing by the parcel materials with the moisture permeability

  • Moisture-proof packaging design
  • For a completely sealed packing
  • Item code:
  • W: fees desiccant (g)
  • R: moisture permeability of moisture-proof packaging material at 40 deg C
  • (g/m2 · 24 hours moisture permeability)
  • A: surface area of moisture-proof packaging material (m2)
  • t: storage days (days)
  • h1: The average humidity of the ambient air during storage (RH%)
  • h2: average humidity inside packaging during storage (RH%)
  • K1:By the constant average temperature θ packaging materials and air:
  • C1: desiccant moisture absorption rate at the start of use (%)
  • C2: desiccant moisture absorption rate in the maximum allowable humidity inside packaging (%)
  • K2:By the coefficient of hygroscopic material inside packing:
  • D: the weight of the hygroscopic material inside the packaging (g)
  • K1 Packaging material and the ambient air temperature by the average.

  • K2 I have a constant depending on the material of the internal moisture-proof packaging
  • Moisture-proof packaging design
  • K2:Constant determined by the hygroscopic material inside the packaging
  • C1: desiccant moisture absorption rate at the start of use (%)
  • C2: desiccant moisture absorption rate in the maximum allowable humidity inside packaging (%)
  • C3: The maximum allowable humidity inside packaging, equilibrium moisture absorption rate of packaging material that is hygroscopic (%)
  • C4: moisture absorption rate of packaging material that is hygroscopic when placed in packaging (%)
  •  
  • For a completely sealed packing

  • Moisture-proof packaging design
  • Item code:
  • W: The amount of desiccant used (g)
  • V: volume of the contents was looking through the packaging, the space in the packaging container volume (m3)
  • H: absolute humidity in the temperature and humidity at the time of packing (g/m3)
  • C1: desiccant moisture absorption rate at the start of use (%)
  • C2: desiccant moisture absorption rate in the maximum allowable humidity inside packaging (%)
