Description

Food packaging materials, raw materials for food packaging materials and packaged foods [Reciprocal reference of the corresponding case]

The present invention is based on Japanese Patent Application No. 2016-079705, filed on Apr. 12, 2016. In the present specification, the patent specification, the patent application scope, and the drawings of the Japanese Patent Application No. 2016-079705 are incorporated by reference.

The present invention relates to food packaging materials, raw materials for food packaging materials, and packaged foods.

In recent years, in the case of food packaging materials, it is possible to easily open the package without directly contacting the food with hands, and it is possible to have a packaging material that hygienicly eats the food. As a food packaging material of such a simple opening type, there is a food packaging material such as a rice ball group which is obtained by half-dividing a food packaging material by tearing a dividing tape.

The rice ball package proposed in Patent Document 1 is In order to keep the rice balls in a hygienic state at the time of eating, the food packaging material of such a simple unsealing type has an outer film and a hand-stained sheet which is fused to the inner side of the outer film. When the rice ball package is unsealed, the fused portion is removed from the outer film, and the hand-stained sheet is prevented from being separated by the hand sheet, and the hand-soiled sheet is prevented from being held on the side of the rice ball. Dirty sheets to hold the rice balls.

However, in order to prevent the hand-stained sheet from being easily removed from the outer packaging film and weaken the fusion strength of the fusion portion, it is possible to prevent the hand from soiling the sheet from the outside in the case of transportation or the like. The possibility of peeling off the packaging film. After the peeling, the hand is prevented from soiling the sheet, and the food is rubbed to become a main factor that causes the shape of the food to collapse or to scatter the food at the time of opening. On the other hand, if the fusion strength of the fusion portion is enhanced, the simple opening function required for the food packaging material is impaired, and the hand-stained sheet cannot be smoothly peeled off from the outer packaging film. The disadvantage of food disintegration or food scattering during opening. Moreover, the opening strength of the packaged food using such a food packaging material is affected by the peeling strength of the fusion portion when the hand-stained sheet is peeled off from the outer packaging film, and therefore it is necessary to control the use of such a food packaging material. The opening strength of the packaged food is difficult.

The main sheet 100 has at least a packaging film 102 for packaging the food 20, and at least a main sheet separating means 116 for dividing the main sheet 100 into the first portion 104 and the second portion 106. Thereby, the food packaging material 10 can be implemented by simply opening the packaged food 1 shown in FIG. 7 and then taking out the food 20 .

As the main body sheet separating means 116, a means for easily dividing the food packaging material 10 can be employed. For example, the main body sheet separating means 116 may be one or a plurality of divided strips fixedly attached to the packaging film 102, one piece of the packaging film 102 or a plurality of sewing thread holes (referred to as a sewing thread). Ordinary division holes, or one or a plurality of half cut portions of the packaging film 102.

In particular, it is preferable that the main body sheet separating means 116 of the main body sheet 100 is formed to include at least two divided strips 110, 112. As the dividing tapes 110 and 112, it is preferable to use a dividing tape composed of a synthetic resin tape such as polyethylene or polypropylene. In this case, the dividing tapes 110 and 112 are provided integrally and fixedly on the packaging film 102. Main face.

The division belts 110 and 112 are linearly arranged along the longitudinal direction of the main body sheet 100, and the two divided belts 110 and 112 are arranged in parallel. According to this manner, by the dividing strips 110, 112, the opening tape 114 which is separated from the body sheet 100 by the dividing belts 110, 112 can be expanded, and wrinkles are not generated on the dividing belts 110, 112. circle The body sheet 100 is divided by the dividing belts 110, 112. Each of the divided tapes 110 and 112 may have a width of 2.5 mm or more in order to facilitate opening of the food packaging material 10. In addition, as the shape of the division belts 110 and 112, a linear shape is preferable, but the shape is not limited thereto, and a conventional shape such as a wave shape, a curved shape, or an arc shape may be employed. For example, the dividing belts 110 and 112 may have a wave shape arranged to cross each other.
