SUSCEPTOR INK
The invention deals with a new susceptor ink useful for microwaveable packages, which changes the current microwaveable packaging concept. The ink composition consists of metallic particles; particles of at least two semiconductor materials; and one or more alkaline or alkaline earth metal salts; all of which are dispersed in a vehicle.
This newly developed ink enhances heating and browning of packaged food, in the same manner as conventional susceptors, while overcoming the disadvantages of conventional susceptors.
In comparison with traditional susceptors – made of metallized polyester films typically laminated to paperboard or in multilayer film structures-, our susceptor is an ink that can be applied by conventional printing methods. It allows printing the susceptor in many sizes, shapes and designs. This also simplifies the package manufacturing process by omitting the extra metallized polyester susceptor film, hence making the package even more inexpensive and more recyclable.
This susceptor ink can be applied to many types of packages, such as:
-
Popcorn microwaveable bags
-
Crisping sleeves for bakery products and sandwiches
-
Pizza trays
-
Other microwavable food packages
The susceptor composition, the resulting ink, and the packages containing such susceptor ink have been protected by the following intellectual property rights:
