Pictured below is a 3 piece polyester label set. The total thickness of each label is 3 mil. Worded in English and French, the product it labels is sold in the US and in French speaking countries.

The symbols that are used on the 2nd polyester label of the set have 2 warning symbols: a triangle with an exclamation point and another triangle with a crooked arrow pointing down. Both are internationally recognized symbols (or pictorials). The triangle with an exclamation point signals "Danger!" and the triangle with a crooked arrow pointing down represents an electrical hazard.
These polyester labels were produced on 3 separate rolls using the Thermal Transfer process (also known as Hot Stamp). The customer had the option of 3 different methods of final packaging: 3 separate rolls; 1 small bag containing each label (the customer ordered 25 of each label, making 25 sets of 3 labels), or 1 bag of each label. This particular customer chose to take 3 bags of 25 labels.
Polyester product labels are an excellent method of branding an item and providing instructions or information about a product. The adhesive used may be permanent or a special adhesive may be used that would allow the polyester label to be removed without damaging the surface of an item.
