Abstract
Provided is a humidity indicator card including: blotting paper; antistatic layers disposed on upper and lower portions of the blotting paper; and humidity indication units disposed on one surface of the antistatic layer, wherein the antistatic layer includes an antistatic composition including conductive carbon black, and the conductive carbon black is included at 1 to 30 parts by weight based on 100 parts by weight of the antistatic composition, and the humidity indicator card may provide an excellent antistatic effect.
Claims17
A humidity indicator card with an added antistatic function comprising:
- blotting paper;
- antistatic layers disposed on upper and lower portions of the blotting paper;
- and
- humidity indication units disposed on one surface of the antistatic layer,
- wherein the antistatic layer includes an antistatic composition including conductive carbon black, and
- the conductive carbon black is included at 1 to 30 parts by weight based on 100 parts by weight of the antistatic composition.
A method for manufacturing a humidity indicator card with an added antistatic function, the method comprising:
- (S10) applying an antistatic composition including conductive carbon black on upper and lower portions of blotting paper to form antistatic layers;
- (S20) forming humidity indication units on one surface of the antistatic layer to manufacture a humidity indicator card;
- and
- (S30) drying the humidity indicator card,
- wherein the conductive carbon black is included at 1 to 30 parts by weight based on 100 parts by weight of the antistatic composition.
