Precious Plastic Stamps

Set of 5 coins you can use as stamps to mark your products with the respective plastic type.

Included plastic types:

2 - HDPE (High Density Polyethylene)

4 - LDPE (Low Density Polyethylene)

To mark your plastic you heat up the coin and stamp it into the product.

This does not only make sure that plastic types won't get mixed up in future processes, it is also like a Precious Plastic trademark - showing that you've gone through all the steps to make your product valuable. :)

My ‘coins’ arrived today and I’m very pleased with them. As one of the way to use the coin is to heat it with a soldering iron, Ryan that would suggest they are a metal alloy.

Ive got a set of stamps ready for when we start to produce our precious plastics. Can I suggest that the next format include a stub or peg on the rear so you can grip them easily with pliers rather than trying to hold them by the edge?
