Food packaging material for microwave oven {FOOD PACKAGE FOR MICROWAVE OVEN}

The present invention relates to a food packaging material for a microwave oven, and more particularly, by forming a micro-pore forming zone in the food packaging material, the food packaging material can be put directly into the microwave without cooking the food packaging material so that water vapor remains in the food. It relates to a food packaging material for a microwave oven that allows you to feel its own taste.

In recent years, the dietary culture has tended to prefer frozen packaged foods that can be cooked quickly and easily.

Such frozen packaged food is mainly cooked using a microwave oven.

When the frozen packaged food is put into the heating chamber of the microwave oven and the microwave oven is operated, the high frequency emitted inside the heating chamber collides with the food.

At this time, the frozen food collided with high frequency generates friction heat while collision between molecules occurs inside the food. The frictional heat generated in the frozen food is converted into thermal energy to heat the food.

As described above, since the microwave oven can be cooked and thawed without changing the shape of the food, it is often used when cooking various types of packaged foods such as frozen dumplings, frozen pizza, steamed bread, and steamed rice.

Foods such as frozen dumplings, frozen pizzas, steamed buns, and steamed rice must contain an appropriate amount of moisture to properly taste. However, when cooking in a conventional microwave oven, the food is packaged and cooked, so the water evaporates and the food is inherent. There is a problem that does not taste.

That is, a packaged food such as frozen dumplings or frozen pizza has a problem in that a lot of moisture is evaporated because the food is removed after the packaging material is cooked in a microwave oven.

In addition, when the food packaging material is not peeled off when cooking in a microwave oven, there is a problem in that the packaging material bursts and is fused to the metal wall of the heating chamber to damage the microwave oven.

In order to solve the above-mentioned problem, the utility food packaging material of the Korean Utility Model Registration No. 01929376 has been formed with several micropores having a diameter of 0.2-0.5 mm in a portion of the packaging material and sealed the micropores with a hot melt adhesive tape. .
