That is, the food 6 is placed on a tray 3, covered in a cylindrical shape with the packaging film 1, sealed 4 at the bottom as shown in FIG. 2, and sealed 5 at both ends as shown in FIG. And the time to turn on the microwave! Follow the time specified by the manufacturer in the instructions, or determine the end point empirically by observing the steam coming out of the steam vent through the microwave window. @Although it is a simple guideline, 1. For example, if the contents are frozen food, there is a difference in the appropriate energization time between completely frozen and thawed, so please use the stated time. must be corrected, and the latter requires at least some experience. It would be really convenient if this microwave heating operation could be easily confirmed whether it has reached a proper state regardless of whether the user has experience or not.

(Example 1) In order to make G4 packaging film of the present invention, as shown in Fig. 3, 8 parts of polyethylene resin and 2 parts of EVAt#l resin were mixed to form a film for thermal adhesion to a thickness of 0.03 mm. Prepare a film 7 of
Cut it vertically with a knife 9 to 10 degrees, paste the second layer, and add the fourth layer.
A packaging material having the cross section shown in the figure was obtained. Using this laminated film, the cooked frozen food placed on the tray 3 as shown in FIG. Seal 4 was applied, and both ends were further sealed 5 to complete the packaging.

This tightly packaged food was placed in a microwave oven, and the timer was set to an appropriate time (in this case, it was set to 10 minutes) and the electricity was turned on. After about 3 minutes, the tear portion 10 begins to expand somewhat, and the inner layer 7 begins to swell from the gap, and after 4 minutes, the crack portion 1
In some cases, the bag broke and flash steam filled the microwave (Fig. 7). At this time, the electricity was turned off, the food was removed, and it was confirmed that the food was heated to a satisfactory level.

The function of the film 7 for thermal adhesion in the structure of the packaging material used in this example (see the fourth cross-sectional view) is as follows:
The area that is compositely bonded is in charge of airtightness and adhesion, and the vertical tear portion 10 of the polyester film on the surface is responsible for airtightness and adhesiveness.

While maintaining airtightness during storage, when heating in the microwave, the internal heat softens like other parts, but the cooking progresses and the inside of the package remains intact until the end of heating.* When the water vapor is discharged, the cut 1o of the top polyester film 8 is pushed aside and expanded, contributing to maintaining the internal pressure of the package up to the film's own elongation limit with respect to temperature and internal pressure, and explodes when the elongation limit is reached. It is something that causes Therefore, if the physical properties of the film are designed to have heat resistance and extensibility by selecting the type and composition of the synthetic resin, it will be possible to match the properties and conditions of the encapsulated food and to ensure that the film 7 expands at the end of proper heating. Destruction (Figure 7) can be caused, of course 2. ::(7)llqAI! 1!

It was pressed with a 5 degree indenter to form a completely sealed body, and then placed in a microwave oven and turned on. After 4 minutes, a portion of the adhesive 13 came off and water vapor was expelled all at once. and,
The heating conditions were appropriate. However, as a result of numerous tests, it has been found that there is no significant variation in the proper peeling time depending on the temperature and pressing force during adhesive bonding, and if a stable adhesive can be obtained, this method can be used. Also, the effects of the present invention can be realized.

According to the present invention, the instantaneous discharge of water vapor from the packaging at the appropriate time can be easily detected by equipping the microwave oven with a sensor. I! It is very easy to detect the momentary fogging inside the microwave when steam is being discharged using a light sensor, humidity sensor, or temperature sensor, so if you modify the microwave for this type of use, you can press the power switch. This can contribute to the emergence of a new type of microwave oven that can automatically turn off electricity immediately after proper heating.
