Air permeable bagging with iron wire available for seizing fruitage

Abstract

An air-permeable sleeve bag for protecting the fruit on the tree is a plastic film bag which has higher left and lower right. It has an upper thermosealing line for sealing part of top edge to leave a fruit entrance, a lower thermosealing line for sealing part of bottom edge to leave an air and water permeable opening and an iron wire for banding the bag.

Description

technical field [0001] This invention relates to plastic film articles. Especially in the field of plastic film bag products for fruit tree cultivation. Background technique [0002] Existing fruit bagging, such as Chinese patent No. 200420032985.8, is a single bag made of double-layer plastic film. At the entrance of the fruit cover, a thin iron wire is longitudinally arranged at the left or right edge position of the bag body. When in use, put the young fruit into the entrance of the young fruit cover, then pleat and press the upper periphery outward, and finally put the iron wire on the folded place to fold outward and fix it, so that the bagged young fruit cover can be sealed by the hardness of the iron wire. The entrance is tied tightly to prevent rainwater and pests from entering the inside of the bag from the entrance of the young fruit cover. This kind of fruit bagging is because the iron wire used to tie the bag mouth is vertically arranged on the edge of the bag...

AI Technical Summary

Problems solved by technology

This kind of fruit bagging is because the iron wire used to tie the bag mouth is vertically arranged on the edge of the bagging, and the upper periphery of the bag body is horizontal and straight, so the bagging will inevitably be tilted during use, and the fruit in the bag will be squeezed. It is easily deformed; when the bag mouth is tightened, the inclined shape of the bag necessarily requires the thin iron wire to reach a certain length, at least one-third of the length of the left and right perimeters, (see Figure 4 ) and when binding, all the positions on the upper periphery are all pleated into the enclosing position of the iron wire, so that the length of the effective space of the fruit in the bag is reduced, resulting in waste of raw materials; There is a fixed connection between the binding part and the bag body without a buffer area, which will inevitably lead to the length of the entire bag body being greater than the length of the bag body without iron wire, so that the overall utilization rate of the bagging is not high, wasting the effective space and causing the wire , plastic film and other materials waste
