Similarly, it is asked, can you shrink Number 1 plastic?

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. The #6 plastic with the ridges has a pretty neat effect when made into a shrinky dink.

Secondly, what is made of #6 plastic? Plastic No. 6 plastics are found in disposable plates and cups, meat trays, egg cartons, carry-out containers, aspirin bottles and compact disc cases. You should particularly watch out for insulated Styrofoam cups which, when heated, can release potentially toxic breakdown products like styrene into your coffee or tea.

One may also ask, how big should I make my Shrinky Dinks?

Shrinky Dinks are usually sold as 8-inch by 10-inch plastic sheets. Use colored pencils, markers, and ink on Shrinky Dinks. Use the colored pencil on the rough side of the sheets, and use Sharpie or permanent marker on the smooth side.

What number is shrink plastic?

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. When manufactured, raw polystyrene is heated, rolled out into thin sheets and then rapidly cooled so that it can retain its shape.
