[0044] figure 1 It is a plan view showing the first embodiment in which the fruit and vegetable packaging bag of the present invention is used for packaging bananas as an example of the fruit and vegetable packaging body of the present invention, figure 2 yes means figure 1 A perspective view of the unpacked state of the fruit and vegetable packaging bag in . in addition, figure 1 with figure 2 (for Figure 3 ~ Figure 8In the same way), for the convenience of explanation, the ventilation holes of the fruit and vegetable packaging bag are exaggeratedly shown, and the size (opening area) and ratio of the ventilation holes to the whole fruit and vegetable packaging bag are greatly different from the actual situation. In addition, the packaging bag for fruits and vegetables has a rectangular shape in a plan view, and the direction along the short sides thereof will be referred to as the x direction, and the direction along the long sides will be referred to as the y directio...

[0080] image 3 It is a plan view showing the second embodiment of the fruit and vegetable packaging bag (unpacked state) of the present invention, Figure 4 is to use image 3 A cross-sectional view ( image 3 A-A line sectional view in).

[0081] Hereinafter, a second embodiment of the fruit and vegetable packaging bag and the fruit and vegetable packaging body of the present invention will be described with reference to these drawings, but the description will focus on the differences from the above-mentioned embodiment, and the description of the same content will be omitted.

[0082] This embodiment is the same as the first embodiment described above except that the relationship between the size of the first opening 21 and the size of the second opening 31 is different. Such as image 3 As shown, in Embodiment 1, each first opening 21 and each second opening 31 have different sizes (opening areas) from each other.

[0083] Specifically, in the packaging bag 1, when v...

[0088] Figure 5 It is a plan view which shows the 3rd Embodiment of the packaging bag for fruits and vegetables (unpacked state) of this invention.

[0089] Hereinafter, a third embodiment of the fruit and vegetable packaging bag and the fruit and vegetable packaging body of the present invention will be described with reference to this figure, but the description will focus on the differences from the above-mentioned embodiment, and the description of the same content will be omitted.

[0090] This embodiment is the same as the above-mentioned first embodiment except that the formation direction (longitudinal direction) of the second opening 21 is different. Such as Figure 5 As shown, in the packaging bag 1 of this embodiment, each second opening 31 is formed such that its longitudinal direction is along the direction intersecting with the longitudinal direction of each first opening 21 , that is, the x direction.

[0091] Thus, the longitudinal central portion of the fir...

Abstract

This produce packaging bag to be used for packaging produce is made to have a bag shape by overlaying a first film and a second film that are each composed of a synthetic resin film. An insertion opening for putting produce inside the bag opens, and the side opposite the insertion opening is closed. The first film has at least one first opening part, and the second film has at least one second opening part. When the first film and the second film are viewed from the thickness direction thereof, at least part of one of the first opening part and the second opening part that are formed at proximate positions overlaps at least part of the other opening part. The present invention can thereby provide a produce packaging bag for which the treatment of a film is easy and in which the freshness of produce can be preserved by means of a modified atmosphere effect without detracting from the visual appearance of the film, even if the film is treated. The present invention can also thereby provide a produce packaged body wherein produce is packaged in said produce packaging bag.

Description

technical field [0001] The invention relates to a fruit and vegetable packaging bag and a fruit and vegetable packaging body. Background technique [0002] It is known that the respiration of fruits and vegetables is inhibited in an appropriate low-oxygen and high-carbon dioxide environment where the oxygen concentration is appropriately lower than the atmosphere and the carbon dioxide concentration is appropriately higher than the atmosphere, which can reduce their deterioration or post-ripening. In an environment of low oxygen and high carbon dioxide that is too severe above the atmosphere, deterioration such as abnormal odor and softening is accelerated due to abnormal metabolism. [0003] In recent years, the practical application of packaging technology for maintaining the freshness of fruits and vegetables using this principle is progressing. In this packaging technology, fruits and vegetables are packaged with packaging materials, and the gas concentration in the pac...
