1、 Fruit bag non-woven fabric is a specialized material that is waterproof and breathable. It is specially processed and customized according to the special growth characteristics of grapes. Based on the diameter of water vapor molecules being 0.0004 microns, the minimum diameter in rainwater is 20 microns for light mist, and the diameter in drizzle is as high as 400 microns. The opening diameter of this non-woven fabric is 700 times larger than that of water vapor molecules and about 10000 times smaller than that of water droplets, making it waterproof and breathable. Since rainwater cannot corrode it, it can significantly reduce the degree of disease.
2、 Special bags for insect and bacterial prevention have improved the brightness of the fruit surface and reduced the erosion of mold diseases.
3、 Bird proof special bag is designed to prevent birds. Paper bags become fragile after being exposed to sunlight and are washed away by rainwater, making them soft and easily broken by birds pecking at them. When the bag is broken, various problems and diseases will occur, reducing fruit quality and yield. Due to its good toughness, the special bag is not afraid of sunlight and rain, so birds cannot peck it, which can save the cost of bird proof nets and reduce the occurrence of diseases.
4、 Translucency
① Special bags have light transmission performance, paper bags are not transparent, and the internal growth cannot be seen. Due to their semi transparency, special bags can see the ripeness and disease of the fruit for timely treatment.
② Especially suitable for sightseeing and picking gardens, paper bags are not suitable for tourists to see the inside and do not belong to the characteristics of grape growth, resulting in messy picking. Special bagging can be used without removing the bag, allowing them to know whether it is ripe or not, reducing the workload of growers.
③ The special bagging has a high transmittance of natural light, significantly increasing the content of soluble solids, anthocyanins, vitamin C, etc. in the berries, improving the comprehensive fresh food quality of grapes, and increasing the degree of coloring.
5、 Improving the micro domain environment with specialized bagging can effectively improve the micro domain environment for grape ear growth. Due to good breathability, the changes in humidity and temperature inside the fruit bag are milder compared to paper bags, and the duration of extreme temperature and humidity is shorter. The fruit ear can grow well, improving the comprehensive fresh food quality of grapes.
