Exploring the advantages of susceptor films
Susceptor films are commonly used in the food industry to package foods – particularly those that require heating in the microwave. Known for a number of qualities, how do susceptor films work, and what advantages do they offer?
In the microwave, the susceptor film allows temperature levels to rise and pass to foods either by the process of infrared radiation or by conduction.
Although microwaving allows foods to get nice and hot, the process of microwaving by itself won’t typically give foods the attractive, lightly browned or crisp finishes that makes food look (and taste) more appetizing. Susceptor films, therefore, can be particularly advantageous as they can support adding these looks and textures to microwavable foods.
Susceptor films are often used by brands that produce foods where a little browning or crisping makes the product look more tantalizing (think nuggets, pastries or pies). Microwave chips for example, look all the more enticing with a little color, making them more reminiscent of a restaurant-style finish, and susceptor film can add just that touch, even though the product has only been heated in the microwave.
