Shrinky Dinks are thin, flexible polystyrene plastic sheets that can be cut with standard household scissors. The sheets are made from plastic with the #6 recycling code, which is also known as polystyrene or PS. When heated, the plastic shrinks to about a third of its original size, becoming nine times thicker and retaining its coloured design. The sheets can be coloured with various materials such as felt-tip pens, acrylic paint, or coloured pencils, but not with oily or waxy substances.

The best plastic for Shrinky Dinks is #6 plastic
Shrinky Dinks are sheets of polystyrene plastic that, when heated, become nine times thicker while shrinking to about a third of their original size. They are commonly used as a children's toy and activity kit, but they have also found applications in art therapy and nanotechnology.
When looking for #6 plastic, it may be helpful to know that it is not widely used for food packaging. However, some sources suggest that it can be found in local grocery store deli boxes, rotisserie chicken boxes, and certain berry cartons.
Once you have obtained #6 plastic, it is important to wash and remove any labels before cutting out a flat section to use. This plastic can then be decorated with permanent markers, stamps, or traced designs, and baked in the oven to create your own Shrinky Dink charms.
While #6 plastic is the best option for creating your own Shrinky Dinks, it may not always produce perfect results. Even when using this type of plastic, your creations may turn out slightly warped or distorted, so it is important to keep this in mind when planning your projects.

#6 plastic is found in takeout containers and grocery store baked goods
Shrinky Dinks are thin, flexible polystyrene plastic (#6) sheets that can be cut with standard household scissors. They are a popular arts and crafts product, especially for children, who can colour the sheets with various media before cutting them into shapes. When heated, the plastic shrinks and becomes thicker and more rigid, retaining the coloured design.
#6 plastic is also found in takeout containers and grocery store baked goods. This includes rotisserie chicken boxes and containers from the local grocery store deli. If you're looking to use recycled #6 plastic for Shrinky Dinks crafts, these containers can be a good source. However, it's important to note that not all #6 plastic containers may be smooth, and some may have warnings or stamps on them that can affect the colouring process.
While #6 plastic is commonly used for Shrinky Dinks, it's important to be cautious when using it for food storage. #6 plastic containers can leach chemicals and plasticizers into food, especially when heated. These chemicals, such as bisphenols and phthalates, have been linked to various health concerns. It's recommended to avoid heating food in plastic containers and to be aware of the potential risks associated with plastic packaging.
To reduce exposure to potentially harmful chemicals, consumers can opt for frozen meals from the grocery store or carryout food from restaurants that use alternative containers. It's also important to note that the term ""microwave-safe" on plastic containers only indicates that the container will not melt in the microwave, not that it is free from releasing chemicals into food.
Overall, while #6 plastic is versatile and suitable for Shrinky Dinks crafts, it's important to be mindful of its potential health risks when used for food storage and to take appropriate precautions.

Recycled plastic can be used, but results vary
Shrinky Dinks are sheets of polystyrene plastic (#6) that can be cut, coloured, and then shrunk in the oven. The sheets can be coloured with felt-tip pens, acrylic paint, or coloured pencils, but not with oily or waxy substances such as crayons or oil paint.
Recycled plastic can be used for Shrinky Dinks, but the results vary. Only one kind of plastic can be used as a Shrinky Dink substitute, and that is plastic stamped with a #6 recycle code. Other kinds of plastic will not work, and some might even be dangerous. #6 plastic behaves similarly to store-bought Shrinky Dinks, but it is not widely used. For example, berry cartons are made from #1 plastic, which is not suitable for Shrinky Dinks. Deli boxes and rotisserie chicken boxes are made from #6 plastic, but the latter can be lumpy and have warnings stamped into them, which can affect the colouring process.
The process of shrinking plastic in the oven is good for the environment because it uses less carbon. However, recycling programs in many locations do not recycle #6 plastic. Therefore, it is better to reuse the plastic to design something useful, such as holiday ornaments, keychains, or zipper pulls, rather than simply shrinking it.

Real Shrinky Dinks shrink to 1/3 of their size at 350 degrees Fahrenheit
Shrinky Dinks are sheets of polystyrene plastic that can be cut with standard household scissors. They are a popular arts-and-crafts activity, especially for children. The sheets can be coloured with various materials such as markers, coloured pencils, and paint before being heated and shrunk.
When heated, Shrinky Dinks shrink to about a third of their original size and become nine times thicker. This occurs at temperatures of around 350 degrees Fahrenheit. The horizontal and vertical dimensions reduce, resulting in hard, flat forms that retain their initial colour and shape. The finished piece will have brighter and bolder artwork that can be more easily preserved.
The base material for Shrinky Dinks is thin, flexible polystyrene plastic (#6). This type of plastic is commonly used in food packaging, such as salad bar containers and clear clamshell containers. It is important to note that only #6 plastic will shrink correctly when used as a substitute for store-bought Shrinky Dinks. Other types of plastic may not work as well or may even be dangerous.
Recycled #6 plastic can be used to create homemade Shrinky Dinks. However, it may not produce the same results as store-bought Shrinky Dinks. The plastic should be relatively thick and smooth for optimal results. It can be coloured with permanent markers, and the colours will darken as the plastic shrinks.
Shrinky Dinks have also been used for practical applications beyond arts and crafts. Scientists have employed Shrinky Dinks in the field of nanotechnology, where the ability to print and shrink patterns on the plastic has proven useful for investigations at the nano-scale.

You can use permanent markers, dry-erase markers, and regular markers on Shrinky Dinks
Shrinky Dinks are sheets of polystyrene plastic (#6) that can be cut and coloured before heating to create hard, flat forms that retain their initial colour and shape.
Regular water-based markers, such as Sharpies, can be used on Shrinky Dinks. These markers are typically alcohol-based and work well on shrink plastic. You can also use any other type of permanent marker. However, it is important to note that if you are using the frosted, rough-and-ready Shrinky Dinks, regular markers may not work as well, and you may need to use coloured pencils instead.
Additionally, dry-erase markers can be used on Shrinky Dinks. These markers are also typically alcohol-based and will provide a similar effect to permanent markers.
When choosing a marker, it is important to avoid oily or waxy substances, such as crayons or oil paint, as they may melt or burn under high heat. Instead, opt for water-based or alcohol-based markers, or other permanent markers, to ensure your design retains its colour and shape during the heating process.
