Understanding Shrink Plastic: A Brief Overview
Before we tackle the microwave question, let’s understand what shrink plastic actually is.
What is Shrink Plastic?
Shrink plastic is a type of polymer that, when heated, shrinks down to a smaller size while becoming thicker and denser. It typically comes in sheets, which designers can cut into various shapes and designs. There are two main types of shrink plastic:
- Polyethylene (PE): This is the most common type of shrink plastic, often available in craft stores.
- Polyvinyl chloride (PVC): This type is less common and typically used for industrial applications.
How Does Shrink Plastic Work?
The core principle behind shrink plastic is heat. When exposed to high temperatures, the polymer chains in the plastic begin to retract and contract, thus reducing its size by up to 50% of the original dimensions. The process also makes the material more rigid and robust.
Ways to Heat Shrink Plastic
There are multiple methods for heating shrink plastic, each with its pros and cons. The two most popular methods include:
Using an Oven
