New susceptor increases heat by 20℃ to enhance crispness and browning of foods and reduce cooking time.

Tokyo – February 17, 2021 – Toppan Printing (Toppan) (TYO: 7911), a global leader in communication, security, packaging, décor materials, and electronics solutions, has developed a new and improved version of its Susceptor®, a sheet for heating foods in microwave ovens. The new susceptor achieves added crispness for foods and is an addition to Toppan’s “SMART LIFE-VALUE™ Packaging” lineup, which is part of the recently launched “TOPPAN S-VALUE™ Packaging” range targeting added value for society and fulfilling living. Toppan is launching sales in February targeting microwave oven manufacturers and the processed food, frozen food, and distribution sectors.

With people spending more time at home due to the COVID-19 pandemic, day-to-day living has changed significantly. Growth in at-home consumption has driven needs for products that can be prepared in microwave ovens. Toppan launched its Susceptor® heating sheet for microwave cooking in the 1980s, but with the number of microwavable food products increasing, demand has arisen for more effective heating solutions. To address this, Toppan has developed a new susceptor that achieves a higher maximum surface temperature for added crispness, browning, and shorter preparation times.

Toppan’s Susceptor® is a heat-producing sheet made by using vapor deposition to create a thin layer of aluminum on a polyethylene terephthalate (PET) film, which is then laminated to thin paper. When used in a microwave oven, a susceptor absorbs microwaves and can generate a surface temperature of approximately 200℃ due to induction heating. This makes it possible to heat foods in a short time, adding crispness and browning, without using a flame.

Toppan’s new solution uses paperboard instead of thin paper to achieve a maximum temperature roughly 20℃ higher than that of the conventional Susceptor®. In addition to adding greater crispness, this also helps to accentuate flavor and shorten the time required to cook the food. In addition, because the susceptor film is now applied directly to the full surface of the paperboard, possibilities for design are expanded and the shape of the susceptor can be matched to that of the product it is coupled with.

“The streamlined structure of this new susceptor not only increases the temperature that can be achieved but also makes a range of shapes possible,” said Sachiko Kagawa, Development Manager for Toppan’s Packaging Solutions business. “It aligns with today’s need to enhance convenience for consumers eating at-home and brings even better results for microwave cooking.”

The new susceptor will be on display in the Toppan Booth (S1-12, South Hall 1) at TOKYO PACK 2021, which will be held at the Tokyo Big Sight exhibition center from February 24 to 26.
