What number of plastic can be used for Shrinky Dinks?
The sheets of plastic you get in a Shrinky Dinks kit is polystyrene—the same stuff as recycled plastic #6, which is commonly used for those clear clamshell containers you see in cafeterias.

They barely shrunk, barely thickened, and several never uncurled. Batch #3 was the best shrinky dink, in that they shrunk well, thickened well, and stayed flat.
You can use number 5 plastic for shrinky dinks or number 6 plastic.
Some plastics will shrink when you get them hot. Two of these are polystyrene, the material in foam cups and plastic food containers, and the other is polyester, from which soda bottles are made. You can make your own shrinking polymers by baking polystyrene in a regular oven!
CPET (Crystallized Polyethylene Terephthalate)
It can typically withstand temperatures between 32 degrees Fahrenheit (F) and 400 degrees F. As a result, CPET is safe to use in the oven up to 400 degrees F. CPET is generally used for baking pans, trays, and containers.
Sharpies, Acrylic Paint Pens, or Colored Pencils:
Our pigment of choice for Shrinky Dinks would be permanent markers (sharpies). They work well for a variety of ages and are ready to roll straight out of the package.
Try heating it longer. I've never done whole sheets before either. One thing that I did find was that although the directions say to heat the plastic on cut up brown paper sack, I got better results by heating directly on the cookie sheet.

Aluminum foil will work fine, but wax paper should never go in the oven. Additionally, never bake a shrinky dink on an uncovered baking sheet. You will run the risk of it getting stuck.
Number 1 plastic shrinks a little, but not much and also sometimes just turns white and curls – it's not a good material for DIY shrinky dinks.
Another way to keep Shrinky Dinks sealed is to place them inside a Ziploc baggie before baking. You can also freeze them for a short period of time or put them in the refrigerator immediately after baking. If sealing isn't an option, then you'll need to discard the Shrinky Dinks if they shrink during baking.
I used acrylic paint to make my jewels pink [for breast cancer awareness month] and coated them with mode-podge to give them a little shine. I used hot glue gun to attach the gems to the Shrinky-Dink pieces. Added the chain + clasps and Viola- done!
To summarize, plastics in categories #2, #4 and #5 are generally considered safe. Be weary of putting them in the microwave, even if they are labeled “microwave-safe”. Plastics #1, #3, #6 and #7 should be used with varying to extreme caution, especially around food or drink.

Polytetrafluoroethylene (PTFE)
PTFE has one of the highest melting points of any thermoplastic at 327°C, and a very large operating temperature range. It's thermally stable enough to be used anywhere between -200°C and +260°C.
This kind of plastic is known as. No worries!
Placing a heavy weight vellum or piece of parchment paper on top of your projects while shrinking will minimize curling and sticking.
The parchment helps keep it from happening to a degree, but it is TOTALLY natural for shrinky dinks to curl up, and as long as it doesn't fold up and touch itself, it will flatten back out by leaving it in the heat.
Some clear plastic bottles and deli containers can be turned into shrink art. Shinky Dinks is the name of a type of shrink plastic. When heated, shrink plastic reduces in size. Designs drawn or printed on shrink plastic reduce too.

The shrinkage of molded plastic parts can be as much as 20% by volume, when measured at the processing temperature and the ambient temperature.
Low temperatures have a direct effect on a plastic's structure, causing molecular chains to shrink. In some cases, this can have a significant impact on the mechanical properties of some plastics.
Although the microwave isn't actively warming the plastic, foods -- especially those rich in sugar or fats -- can easily reach temperatures that certain containers can't tolerate. "You can easily take something right out of the deli, put it in the microwave, and end up shrink-wrapping …

Plastic injection molded part shrinkage units are expressed as thousandths of an inch per linear inch (0.00X /in/in). Typical shrink rates vary between 0.001/in/in and . 020/in/in – depending on material, wall thickness, cooling rates and other variables. The average rate of shrinkage is around 0.006/in/in.
Some polystyrene items, such as number 6 plastic, can be used like shrink plastic.
Bake the Plastic
Heat your oven to 325 degrees Fahrenheit, and place your plastic drawings in the center of a cookie sheet. Once the oven is preheated, place the cookie sheet on the top rack. After about a minute, the plastic will curl, shrink, and then flatten out.
