   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

View More >

   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.

Special Note

1, the product performance and storage and testing of environmental temperature and humidity, film thickness is directly related to the specific subject to the actual measurement.

2, the performance of different types of products there will be significant differences in the specific model to select the actual subject.




The production process of POLYVA pva water soluble film goes through real-time inspection. In nearly every production stage, random inspection in terms of the fiber quality, weaving quality, colorfastness to washing or rubbing, as well as overall tensile strength is strictly carried out.
POLYVA dissolvable plastic material is thoroughly tested. Both its physical properties such as shrinkage rate for cloth, resilience, and fabric stiffness and chemical properties such as formaldehyde and PH content are required to meet the specific standards.
POLYVA pva water soluble film is thoroughly tested. The test is carried out by our QC professionals who conduct pull tests and fatigue tests on each style of bag.
The raw materials or parts of POLYVA pva water soluble film would be inspected before production. The materials or parts are guaranteed eco-friendly and non-toxic by the suppliers who hold gift&crafts quality certifications.
The production of POLYVA pva water soluble film consists of two major steps. The first step is the extraction of raw materials; the second step is the grinding into pre-treated building materials.
The product has a long service life. Its full-shield design better helps avoid the leakage problem, which more perfectly prevents its components from damage.
