Degradable environment-friendly PE packaging bag and manufacturing method thereof

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.

[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
