Tips for Successful Cutting
To achieve clean, consistent cuts when working with shrink plastic, consider these best practices:
The Sandwich: Since these are thin metal dies, you generally need to use the manufacturer-recommended platform system for "wafer-thin" or "thin" dies. 
Multiple Passes: Because shrink plastic can be denser or have a different texture than paper, running the die through your machine twice (forward and backward) ensures the die fully penetrates the material.
Intricate Details: If your design is very detailed, running the die through at a slight angle or placing it toward the edge of the cutting plates can sometimes provide a cleaner cut.
Alignment: When layering, if you are using multiple dies at once, use a small piece of low-tack painter's tape or washi tape to secure the dies to the shrink plastic before running them through the machine to prevent them from shifting.
