Moistureproof bag / Primary packaging

After a period of careful observation on the ways people using and storing the washing powder, we have found that there is still room for improvement in the design of the washing powder bag .
1.A device made of two flexible seals(it can be opened by hand)is stuck to the open part of the washing powder bag,thus no clip is needed.Not only can the flavouring essence be retained, the formation of washing powder lump due to moisture can be prevented.
2.Top part of the bag is design as a triangle，just like a filter which can prevent power scattering when it is used. This makes customers feel safe and at ease when pouring the powder out.
