Application:
1. The tiny package of fertilizer power, granules, missible oil.
2. Some products which human shouldn't directly contact and the items used in the water.
3. The inner package of pesticide effervescent.
4. Paint, dye and some other chemical products package and seed bags.
Using method:
Produce the appropriate wide roll film according to the weight of the packed pesticide, then use the automatic packaging machine to pack it into single unit.
Application case:
Directly put the packed pesticide unit into water, stir it slightly. The outer water soluble packaging film will be immediately dissolved to release the pesticide. So the active ingredients can be fully used and it can keep user from direct contact with the toxic substance. It will reduce the plastic pollution to the world.
