Trapezia fresh-keeping packaging bag special for single spiked vine

Abstract

The present invention relates to a trapezoidal preserving packaging bag, which is exclusively used for an odd-fringe grape and is made of plastic film. The appearance of the utility model is an isosceles trapezoid which is suitable for the appearance of the odd-fringe grape. The packaging bag comprises a front and a rear trapezoid-shaped plastic films which are in the same size. The two trapezoid-shaped plastic films are overlapped together. Two shorter upper lines of the two same-size and overlapped trapezoid-shaped plastic film thermally combined together; two longer bottom lines are not thermally sealed; so the trapezoidal odd-fringe grape exclusive preserving packaging bag with the bottom lines open is formed. The same intermittent slots or lunules are regularly and evenly distributed on the front and the rear trapezoid-shaped plastic films. So the preserving is even and good; the grape extruding and damaging caused by being piled up in a box are avoided; the preserving time limit of the odd-fringe grape is easily controlled at the same time; the transforming and marketing can be well-planed; partly rotting is avoided; and the marketing cost is reduced.

Description

technical field [0001] The invention belongs to a fresh-keeping appliance for grapes in the field of fresh-keeping agricultural products, in particular to a special trapezoidal fresh-keeping packaging bag for single-ear grapes. Background technique [0002] At present, at the end of the storage and preservation period of grapes, full-case packaging is used in the transportation and sales process of circulation, and the grape products packed in full cases in the transportation and sales process also need to be kept fresh with preservatives. While putting the grapes into the packing box, add the application form of the solid grape preservative to the grape packing box, such as the grape fresh-keeping paper with the solid grape preservative attached, the individually packaged grape preservative and other products. The solid grape preservative is produced by releasing Gas antistaling agent is used to achieve the preservation effect. Since the grape fresh-keeping paper or single-...

Problems solved by technology

While putting the grapes into the packing box, add the application form of the solid grape preservative to the grape packing box, such as the grape fresh-keeping paper with the solid grape preservative attached, the individually packaged grape preservative and other products. The solid grape preservative is produced by releasing Gas antistaling agent is used to achieve the preservation effect. Since the grape preservative paper or single-pack preservative can only be placed at a few points in the packing box, the distribution of the gas preservative released by the fresh-keeping paper or single-pack preservative in the packing box is also the same. Uneven, resulting in uneven preservation of some grapes, some grapes cannot achieve the preservation effect, and deteriorate prematurely, making it impossible to grasp the exact preservation time for each whole box of grapes, affecting transportation and sales, causing some grapes to deteriorate and rot, adding cost of sales

[0003] FCL packaging will also cause the backlog of grapes on the upper layer to the grapes on the lower layer, so the grapes on the bottom layer are often squeezed, damaged and deteriorated
