Pesticide fertilizer water soluble PVA film
Advantages:
1. Completely dissolve, no residue left.
2. Good weather resistance,
3. Green environment-friendly material, no toxic substance contain.
4. Good mechanical property and heat sealing ability.
5. Able to be printed with good quality, ink will dissolve with the bag.
Specification:
1. Size
Bags
Produce as per customer requirements.
Roll film
Thickness（µm） | 25、35、45、75 |
Width (mm) | ≤1000 |
Length (m) | 100~1000 |
The thickness, width of the film can be produced as per customer’s requirements if the order quantity more than 10000 meters.
2. Appearance:
clear, embossing
Application:
Applicable for the single measurement package of fertilizer powder, granules, missible oil.
1. The tiny package of fertilizer powder, 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.
