Background technology
Along with the development of Urbanization in China and the raising of people's living standard, metropolitan vegetables and fruit more and more rely on the other places supply, from the place of production to common people's hand, need to pluck through the place of production, assembly, long-distance transport, wholesale, to the supermarket several links, generally need the time of 2-4 days.Fruits and vegetables are at the length of the halt of wholesale market and generally all longer at the shelf life in supermarket, and owing to lacking suitable preservation technique, the loss rate of China fruit and vegetable is in 20% left and right, and the loss rate of developed country closely has 2.5%, the backwardness of this explanation China preservation technique.
Fruit is dredged fresh-keeping key and is to prevent water loss, surpasses as the fruit and vegetable filter loss to occur more than 5% wilting, and loses commercial value; Plastic sheeting has lower moisture-vapor transmission, has water retention property preferably, therefore really dredge at present fresh-keeping packaging material both at home and abroad and mainly adopt plastic basis material, in order to increase the oxygen gas permeability of plastic basis material, people have developed numerous modified film technique, comprise the various kinds of resin blend, add inorganic particulate pore-creating, laser beam perforation etc., but the fresh-keeping packaging material of preparation generally also is limited under low temperature and uses, the normal-temperature fresh-keeping effect is still undesirable, and reason is that the OTR oxygen transmission rate of plastics can not satisfy the requirement of high respiratory rate under fruits and vegetables normal temperature.Although the report of domestic at present existing many fruit and vegetable fresh-keeping packagings, these existing Fresh-Keeping Packaging Materials have following point:
1 existing Perserving materials is limited to plastic basis material more, also only can reach 10 because the OTR oxygen transmission rate (0TR) of general plastic basis material is the highest
4Ml/m
2.day.atm, can not satisfy the metabolic requirement of fruit and vegetable at normal temperatures, generally only can be as Perserving materials under fruits and vegetables low temperature, and under normal temperature, the fresh-keeping effect to fruits and vegetables is relatively poor, even can make fruits and vegetables generation anaerobic respiration under normal temperature;
(WVTR) is little for the moisture-vapor transmission of 2 existing plastic base Perserving materials, and the moisture that in freshness protection package, the fruits and vegetables metabolism produces easily forms the internal environment of high humidity, causes bacteria breed, accelerates fruits and vegetables and rots;
If 3 increase the permeability to air of plastics fresh-keeping packaging, film thickness need to be reduced, the problem that this brings again packing mechanical property deficiency makes the processing film moulding, and difficulty occurs in the preparation of freshness protection package.
In a word, under fruits and vegetables normal temperature, the respiratory intensity of fruits and vegetables is large, to fresh-keeping packaging material require high, existing plastic basis material Perserving materials generally only is fit to low temperature to be used, the perhaps low fruit and vegetable of respirability intensity only, the fruits and vegetables high for respiratory intensity not only can not play preservation at normal temperatures, accelerates on the contrary fruits and vegetables and rots.
