What are the benefits
Waterproof and breathable
Special bagging material is a waterproof and breathable specialized material, specially processed and customized non-woven fabric according to the special growth characteristics of grapes. Based on the diameter of water vapor molecules being 0.0004 microns, the smallest diameter in rainwater is 20 microns for light mist, and up to 400 microns for drizzle. The pore size 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 can significantly reduce the degree of disease.
Insect and bacteria prevention
Specialized bagging prevents insects, improves the brightness of fruit surface, and reduces the erosion of fungal diseases.
Bird prevention
Specially designed bag for bird protection, the paper bag becomes fragile after exposure to sunlight and becomes soft after being washed by rainwater. It can be easily pecked and broken by birds. Once the bag is broken, various problems and diseases will occur, reducing the quality and yield of the fruit. Due to its good toughness and resistance to sunlight and rainwater, the bag cannot be pecked by birds, saving the cost of bird nets and reducing the occurrence of diseases.
Transparent
① Specialized bagging has transparent properties, while paper bags are opaque and the internal growth cannot be seen. Due to their semi transparency, specialized bagging allows for the visualization of fruit maturity and disease conditions, facilitating timely processing.
② Especially suitable for sightseeing and picking gardens, paper bags are not visible from the inside, and tourists do not belong to the grape growth characteristics and pick them haphazardly. The special bag cover can be used to determine maturity without removing the bag, reducing the workload of growers.
③ The specialized bagging has a high transmittance of natural light, significantly increasing the soluble solids, anthocyanins, vitamin C, and other contents of berries, improving the overall fresh quality of grapes, and enhancing the degree of coloring.
Improve the micro domain environment
Specialized bagging can effectively improve the micro environment for grape ear growth. Due to its good breathability, the humidity and temperature changes inside the bag are milder compared to paper bags, and the duration of extreme temperature and humidity is shorter. The ear can grow well, improving the overall fresh food quality of grapes.
Overall situation: The specialized bag has excellent waterproof, breathable, insect proof, bird proof, bacteria proof, and transparent characteristics, and is also a biodegradable environmentally friendly material. Research has shown that it can effectively improve the micro environment for grape ear growth and significantly increase the soluble solids content of berries. The content of anthocyanins, vitamin C, etc. improves the comprehensive fresh food quality of grapes, enhances the brightness and coloring degree of grape fruits and surfaces, reduces the occurrence of grape diseases such as sunburn, anthracnose, white rot, and gray mold, and reduces the labor production of grape growers.
Is it better to use paper bags or non-woven fabrics for grapes
It’s good to use non-woven fabric for grapes. Non woven fabric can provide certain antibacterial protection, reducing the damage of grapes to bacteria, mold, etc., while paper bags can only maintain appropriate ventilation. Compared to paper bags, non-woven fabric is more durable, reusable, and can reduce the deposition of dust, dirt, and other substances on the surface of grapes. Whether choosing paper bags or non-woven fabrics, the following points are important:
1. Use dry bags to avoid excessive moisture causing decay of grapes.
2. Maintain ventilation and avoid the bag being too tightly sealed to prevent the growth of mold.
3. Regularly inspect and clean the grapes inside the bag, promptly removing any rotten or spoiled parts.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
