Problems solved by technology

[0002] PE packaging bag is a bag used to pack all kinds of food and articles; PE is the abbreviation of polyethylene, which is a thermoplastic resin obtained by polymerization of ethylene; PE packaging bag is a transparent plastic bag that can be used for clothing, Luggage, electronic products and food packaging, with the increasing awareness of environmental protection, degradable and environmentally friendly materials are often added to PE packaging bags in the prior art to form degradable and environmentally friendly PE packaging bags; when the weather is hot, the water source is limited when going out for an outing The cleanliness is not high, and the fruit cannot be washed on the spot. At the same time, there are bacteria on the hands when going out for an outing, so it is difficult to directly contact the fruit, so it is usually washed at home and put in a bag to take away. However, some fruits are not easy to store after cleaning, and the outer surface After the skin film is washed off, it will affect the taste if left for a long time, such as grapes and cherry tomatoes, so at this time, a degradable and environmentally friendly PE packaging bag that can solve the water source problem and wash and eat the fruit is needed at this time
[0003] For example, a Chinese patent with the application number CN201910332702.2 discloses a fruit packaging bag, including a storage box, a power device is provided in the storage box, and a packaging bag is provided on the lower side of the storage box, and the packaging bag contains There is a telescopic device and a roller device, and the power device includes a synchronous belt cavity arranged in the storage box. The device of this technical solution is easy to operate and easy to use. It can not only store fruits in a vacuum state, increase the storage time, and The packaging film is surrounded by gas to prevent the fruit from being damaged during transportation, and it is also convenient for transportation on different road conditions. When not in use, the device can be stored to reduce space occupation; however, this technical solution has a complex structure and high cost. It is not easy to carry, and the fruit under the vacuum package is not as good as the freshly washed and eaten fruit, which causes the limitation of this solution

specific Embodiment approach

[0035] As a specific embodiment of the present invention, the side of the No. 2 water storage chamber 13 away from the No. 1 water storage chamber 12 is provided with a nozzle head 132 and a screw cap 133; One end of the nozzle 132 communicates with the No. 2 water storage chamber 13, and the other end is connected with the screw cap 133 by threads; the interlayer 14 is provided with a through hole 141; the through hole 141 connects the No. 1 water storage chamber 12 and the No. 2 storage chamber. The water chamber 13 is connected; when working, close the No. 1 seal 111 and the No. 2 seal 121, turn the position of the storage chamber 11 to the top of the No. 1 water storage chamber 12 and the No. 2 water storage chamber 13, turn the screw cap 133, open The nozzle head 132 is used to inject water into the No. 2 water storage chamber 13. After injecting 4 / 5 of the water, screw the screw cap 133 on the nozzle head 132 to close the No. 2 water injection chamber; by setting the nozz...

Embodiment approach

[0037] As a specific embodiment of the present invention, a flexible ball 122 is fixedly connected to the center of the inner wall of the No. 1 water storage chamber 12 and the No. 2 water storage chamber 13; when working, the material of the flexible ball 122 is preferably a sponge. Hands alternately press the two flexible balls 122, because the flexible balls 122 themselves have a supporting force, so that the water body will not be crushed or squeezed to break the seal; because the flexible balls 122 themselves have elasticity, they can be reset in time, so that when the No. 1 water storage Cavity 12 and No. 2 water storage chamber 13 leave sufficient reserved space when water is injected; Since the flexible ball 122 is made of sponge material, it can be flattened when it is under pressure, which is convenient for its transportation and sales.

Abstract

The invention relates to the technical field of packaging bags, in particular to a degradable environment-friendly PE packaging bag and a manufacturing method thereof.The degradable environment-friendly PE packaging bag comprises a bag body and a first sealing strip, and the bag body is divided into a storage cavity, a first water storage cavity and a second water storage cavity; the storage cavity and the first water storage cavity are connected in a sealed mode through a second sealing strip, and the storage cavity and the second water storage cavity are connected in a sealed mode through a third sealing strip. The first water storage cavity and the second water storage cavity are separated through an interlayer. The bag body is divided into the storage cavity, the first water storage cavity and the second water storage cavity; the volume ratio of the storage cavity to the first water storage cavity to the second water storage cavity is 2: 1: 1. According to the fruit cleaning device, by alternately pressing the first water storage cavity and the second water storage cavity, water in the first water storage cavity and the second water storage cavity flows upwards to clean fruits in the storage cavities, it is guaranteed that the fruits are tasty and refreshing in taste, and the fruit cleaning device has the advantages of being easy to operate, convenient to use, economical and practical.
