How to Make Plastic that Dissolves in Water

Plastic pollution is one of the major environmental concerns globally. Every year, millions of tons of plastic waste end up in our oceans, harming marine life and ecosystems. As a responsible citizen of the planet, it is essential for us to find sustainable solutions to minimize the impact of plastic waste. One effective approach is to develop and use plastic that dissolves in water. In this article, we will explore the process of making such a plastic.

- PVA (Polyvinyl Alcohol): PVA is a water-soluble polymer that serves as the primary ingredient for making this dissolvable plastic.
- Glycerol: Glycerol acts as a plasticizer to improve the overall flexibility and durability of the plastic.
- Food coloring (optional): If desired, you can add food coloring to give the plastic a more visually appealing appearance.


1. Measure and mix the ingredients: Start by measuring the necessary amount of PVA and glycerol in a clean and dry container. The ratio of PVA to glycerol depends on the desired properties of the plastic. Generally, a 3:1 ratio of PVA to glycerol works well. Adjust the ratio as per your experimentation and requirements. If desired, add a few drops of food coloring at this stage.

2. Heat and dissolve: Place the container with the measured ingredients on a hot plate or stove with low heat. Slowly stir the mixture until the PVA granules completely dissolve and form a homogenous liquid. Ensure that the mixture is heated gently to avoid any chemical reactions or degradation of the polymer.

3. Cooling and shaping: Once the PVA has completely dissolved, turn off the heat and allow the mixture to cool down. During this process, the liquid will start to thicken and eventually solidify into a flexible plastic-like material. You can speed up the cooling process by placing the container in a water bath.

4. Mold and shape: Once the mixture has solidified, remove it from the container and mold it into the desired shape. You can use your hands or molds to shape the plastic accordingly. Ensure that you work quickly as the plastic will start to dissolve when exposed to moisture.

5. Drying: Leave the molded plastic in a dry and well-ventilated area to ensure it is completely dried. This step is crucial as it increases the shelf life of the dissolvable plastic and prevents premature dissolution.

6. Testing: To determine the dissolvability of the plastic, immerse a small piece in a container of water. You will notice that the plastic starts to dissolve and disintegrate over time. This property makes it an ideal material to reduce plastic waste as it can easily be broken down and decomposed.


By making plastic that dissolves in water, we can contribute to reducing the plastic waste problem that plagues our planet. The use of water-soluble plastic offers a sustainable alternative that minimizes long-term pollution while providing similar functionality. Industries and manufacturers should explore the adoption of such environmentally friendly plastic to replace conventional non-biodegradable options. Together, we can protect our environment and ensure a better future for generations to come.
