Mango bagging generally uses paper bags, and some use film bags, but the film bags have poor air permeability, and the weather in the south is hot. Using film bags to cover
mangoes will easily cause the fruit to be burned and lose its commerciality. Therefore, paper bags are generally used for mango bagging. Below I will introduce the specifications of mango bags as follows
In general, paper bags are divided into single-layer paper bags and double-layer paper bags.
⒈Single-layer paper bags can be divided according to color, which can be white or yellow;
⒉Double-layer paper bags include composite paper double-layer and single-color double-layer paper bags.
According to the quality, there are three types of paper bags in our district:
⒈ Paper bags produced by the joint venture with imported paper;
⒉ Paper bags produced from domestic high-quality paper;
⒊ Newspaper bags made by fruit farmers.
The choice of mango bagging materials depends on the quality and the variety
(1) The quality of bagged fruit is closely related to the quality of paper bags.
⒈The quality of the fruit bag is too poor, it can not withstand wind, sun, rain, easily damaged, hardened, resulting in cracked fruit, sunburn, uneven coloring or rough fruit surface.
⒉The quality of the fruit bag is poor, and it does not have the function of preventing and controlling the pests that enter the bag, resulting in a large number of pests and diseases.
3 Poor quality fruit bags are easy to accumulate water, which makes the humidity in the bag high, and the fruit surface will appear rust or even rotten fruit, and lose its commerciality.
⒋Because the paper bag making process is simple and the equipment is not expensive, there are many manufacturers producing paper bags, and there are many unqualified products. There are problems such as poor light transmission, poor waterproofing, and different sizes. Therefore, farmers and friends must use qualified products when choosing. High-quality paper bags should not be broken or deformed, and have a certain porosity and light transmission spectral range. And it has the effects of waterproof and insect proof, sunburn and humidity reduction.
⒌At present, some fruit farmers also use newspaper bagging. Although it has the advantage of low cost, because it is not disinfected, there are many potential germs, and the production is troublesome. The artificial input of bagging is increased, and there are problems such as lead pollution, and the quality of the fruit cannot be guaranteed. , therefore, it is recommended to use mango special bags for fruit bagging,
(2) Different varieties use different materials and specifications
1 Jinhuangmang is a double-layer composite bag with outer yellow and inner black, with a size of 36×22cm;
2 Use yellow or white single-layer bags for purple mangoes or double-layer bags with yellow on the outside and black on the inside, with a size of 27×18cm;
3 Tainong No. 1 is a double-layered bag with outer yellow and inner black or outer yellow and inner red double-layer bag, with a size of 26×18cm;
4 Other varieties are determined according to the specific situation, especially some special varieties. Although bagging can improve the appearance of the fruit, the coloring is not very ideal. Most of the methods are to remove the bag about 10 days before harvest to increase the fruit. face coloring.
