What type of plastic do you need for shrink plastic?

1. Grab your plastic 

For this tutorial, you’re going to need number 6 plastic, so find something that’s labeled with a number 6. It’ll typically have a little recycle sign surrounding the number.

Number 6 plastic isn’t easily recyclable, so it’s the best kind to reuse for any plastic DIYs you may have.

Cutting out the plastic for the DIY

2. Cut the plastic

Cut out the piece of plastic for your keychains, removing any bumpy or textured parts that can’t be used.

3. Print out your designs

Print out the designs for your keychains. Make sure you set the height and width to be several times bigger than you want the keychain to appear because, in a later step, the plastic is going to shrink. 

Tracing the designs onto the plastic

4. Draw your designs on the plastic 

Overlay the piece of plastic over your printed designs and then, using a permanent marker, trace over the image to create the design for your keychains.

6. Punch a hole for the keyring

Make sure to leave a small space around the design and then punch a hole in the space. This is where we’re going to put the keyring.

7. Shrink the plastic in the oven 

Set your oven to 325°F and let it sit in the oven for two minutes on some parchment paper. The plastic will begin to shrivel up and shrink really small, but this is completely normal!

8. Add a keyring

When taken out, the keychain charms will be several times smaller and harder than they were previously. Now we can add the keyring to our charms. If needed, use pliers to close and tighten up the rings.
