Double-layer breathable bag for fruit bagging

Abstract

A double-layer air-permeable fruit bag, comprising two layers of bag bodies inside and outside, the outer bag body is a paper bag, the inner layer bag body is a breathable film bag with micropores, the inner layer bag body is placed in the outer layer bag body, the The left and right peripheries of the outer paper bag body are closed edges and are parallel to each other, and the upper and lower peripheries are open edges. The adjacent part of the lower periphery is provided with a bonding layer for bonding the paper bag, and the inner gas-permeable membrane The left and right peripheries of the bag are closed sides and are parallel to each other, the upper and lower peripheries are open sides, and the adjacent parts of the lower peripheries are provided with heat sealing lines for laminating the films. The surrounding positions are coincident. When using, put the young fruit in and tie the top of the bag tightly. After the fruit is ripe, remove the outer paper bag, leaving only the inner film bag to color the fruit. The fruit bagging of this structure has good ventilation function and bright color, no cracks in the fruit, no bean spot disease, bitter bean disease, the finished fruit is uniform in size, and the commodity value is greatly improved.

Description

technical field [0001] The invention relates to paper and plastic film products, in particular to a double-layer air-permeable fruit bag for fruit tree cultivation. Background technique [0002] Existing fruit bagging, as No. ZL00223133.6 of Chinese patent, is the single bag body that is made by double-deck plastic film, and this bag body is provided with slight air hole, and belt-shaped tie rope is arranged on the bag body. This kind of bagging is fast in use and low in price, but because the fruit grows in the almost transparent bagging, the fruit ripens slowly and the color is not good, so the value is not high. [0003] The task of the present invention is to solve the problems and defects of the prior art and provide a fruit bag made integrally by the machine. It not only has the function of ventilation, but also can make the fruit mature and color quickly in the bag, and the color is bright. The surface is delicate and without cracks, and does not cause bean spot and ...
