Does polymer clay stick to plastic?

Polymer clay is a versatile and popular medium used by artists and crafters to create a wide range of projects. One common question that arises is whether polymer clay sticks to plastic surfaces. In this article, we’ll delve into the topic of adhesion between polymer clay and plastic, exploring the factors that influence stickiness and techniques to achieve successful bonding.

1. Compatibility and Surface Texture

Understanding Adhesion:

Exploring compatibility:

Whether polymer clay sticks to plastic depends on the type of plastic and its surface texture. Some plastics have a smooth and non-porous surface, which can make it challenging for polymer clay to adhere effectively. In such cases, the clay may have difficulty gripping the plastic, leading to potential separation. However, other plastics with a slightly rougher or porous texture may provide a better surface for the clay to bond to.

2. Techniques for Bonding

Ensuring a Secure Bond:

Exploring adhesion techniques:

If you wish to bond polymer clay to plastic, there are several techniques you can employ to improve adhesion:

  • Sanding: Lightly sanding the plastic surface can create a slightly rough texture, enhancing the clay’s ability to stick.
  • Texture Sheets: Applying texture to the plastic using texture sheets or stamps can provide more surface area for the clay to adhere to.
  • Adhesive: Using a compatible adhesive, such as liquid polymer clay or super glue, can help secure the clay to the plastic.
  • Baking: Baking the clay and plastic together can promote bonding, as the clay may fuse slightly to the plastic surface.

3. Compatibility Testing

Experimentation and Exploration:

Testing adhesion on a small scale:

If you’re unsure whether polymer clay will stick to a specific type of plastic, it’s recommended to conduct a compatibility test on a small piece before embarking on a larger project. This test allows you to observe how well the clay adheres to the plastic and whether any additional techniques or preparations are needed for a secure bond.


While polymer clay may not always naturally adhere to plastic surfaces, there are techniques and strategies that can be employed to achieve successful bonding. By considering the compatibility of the plastic, utilizing adhesion techniques, and conducting compatibility tests, you can effectively use polymer clay in combination with plastic materials. Whether you’re creating jewelry, sculptures, or other artistic creations, exploring the possibilities of combining polymer clay and plastic opens up new avenues for creativity and expression.
