Art paper, it is necessary to have high water-resistance and aqueous durability, while also to have good gas permeability, and orchard worker is to fruit bag
The price request of paper is harsh, therefore should reduce production cost as much as possible.
Fruit-nourishing sleeve bag technology results from Japan earliest, is to adopt in fruit growth development overall process to it briefly
A kind of technology for taking protected by bagging is developed so far existing more than 100 years history.Twentieth century early stage, Japanese orchard worker is in order to prevent
Pest damage, mainly carries out fruit-nourishing sleeve bag on grape and pears, and several Nian Houcai are generalized on apple and use.Pass through production practices table
Bright, fruit-nourishing sleeve bag can not only prevent pest damage, but have keep fruit surface bright and clean without rust staining, colour, price height etc. it is excellent
Point.Therefore, fruit-nourishing sleeve bag technology becomes the fruit cultivation technology of Japanese routine.Japan mainly uses waste and old report before nineteen sixty-five
Fruit paper bag is educated in paper production, it is therefore an objective to pre- preventing disease and pest.Thereafter, use main purpose for promote fruit color fruit-nourishing sleeve bag,
It is thus quite welcome by orchard worker, and has developed the fruit-nourishing sleeve bag paper of two layers or three layers of fruit-nourishing sleeve bag paper, multi items and multiple types.
High-new cultivation technique has been widely used in the modernization business orchard of Japan, such as: fruit-nourishing sleeve bag improves fruit shape, using efficient liquid
Fertilizer, priming leaf turn fruit and laying Reflecting mulch film etc.；Wherein, still widely popularize one of fruit-nourishing sleeve bag technology is effective advanced
Fruit cultivation technology.

This allows for orchard worker and tends to select the lower fruit-nourishing sleeve bag of price.Domestic part fruit bag paper plant is produced into reduce
This, sacrifices a part of quality, and orchard worker is extremely harsh to price, and promoting papermaking enterprise constantly reduces production cost, especially
The ground such as Henan turn to production fruit cultivating bag paper in the small-sized paper mill for shutting down edge one after another, and technology is at all unqualified, with regard to participating in educating
The harmful competition of fruit paper bag, all using secondary stock and industrial chemicals inferior, the bad paper bag of single layer, film bag and full secondary stock bag fill
Denounce market, hurts fruit and hurt farming part and occur again and again.
Currently, a variety of fruit-nourishing sleeve bags that domestic many producers are produced, mostly not ideal enough after orchard worker's use, effect
It is poor.Domestic fruit cultivating bag paper common problem is the face of God to be seen, and in the favourable weather (for the crops) time, problem is less, when touching
To the time that rainwater is more or continuous high temperature is short of rain, then several quality problems are completely exposed, and cause huge loss to orchard worker.?
In market competition in recent years, it is most can only limited production low grade fruit-nourishing sleeve bag producer, be eliminated and shut down.Compel domestic market
