Description
Technical field
The invention belongs to the agricultural products fresh-keeping technical field, be specifically related to a kind of far infrared tin foil and preparation method thereof and by its fresh-keeping corrugated box that makes.
Background technology
At present, domestic fruits and vegetables all are to adopt common carton to pack, store and transport in postpartum, and its fresh keeping time is very short, and especially the mutual collision in transportation more is prone to accelerate the rotten time.According to investigations, adopt existing packed in cases fruits and vegetables, China every year will be above 6～8,000 ten thousand tons.
For a long time, agricultural products in China is produced the cultivation of relatively paying attention in antenatal and the product, and has ignored the fresh-retaining preserving in postpartum.In developed country, the post-harvest loss rate of agricultural product is only 1.7%～5.0%; But in China, the fruits and vegetables loss late reaches 20%～30%, nearly 80,000,000,000 yuan of loss total value, and the grain average loss also has 14.8%.Not only can not embody the due commodity value of agricultural product, more be difficult to resolve certainly problem such as sale of fruits and vegetables strange land in postpartum and supply in non-season.
Fresh fruit, vegetables, meat, flowers are the main exported products of China, but packing is very coarse, and preservation technique falls behind, and these agricultural exports are not pass through elementary processing basically.Also need behind the agricultural product of some national import China to repack, get into domestic markets, its market price is high during more than import.Particularly after China entry into the World Trade Organization, downward modulation of tariff, external fruit and vegetable food pours in China market, has more weakened the competitiveness of China's fruit and vegetable food.Reduce fruit and vegetable food and rot to lose, improve the utilization rate of agricultural resource, increase agricultural product added value, become a urgent task of agricultural modernization.Statistics show, if the fruits and vegetables loss of China reduces by 3% to 5%, can reduce 2,000,000 tons of fruit losses every year.As reducing the wastage 15%, the fruits and vegetables output value can increase by 12,000,000,000 yuan.
China is a populous large agricultural country; Fruits and vegetables are produced and grocery trade develops rapidly, but relevant with it product is fresh-keeping, storaging and transport technology is supported the boudoir, and difficulty is advanced farmers''s door; Food hygiene index and international norm have gap, and food security also has the situation that does not conform with health requirements more.It is reported, 300,000,000 tons of the annual yield of vegetables of China, fruits output surpasses 6,000 ten thousand tons, but because the fresh-keeping industry of China falls behind, has every year 8000 ten thousand tons fruits and vegetables to rot, nearly 80,000,000,000 yuan of loss total value.That is to say have 20% fruit and vegetable in the process of circulation, to become rubbish approximately.Packing improper then is the major reason that causes the rotten loss of fruit.According to statistics, developed country's agricultural product storage capacity in postpartum can account for 70%～80% of the total volume of commodities, and China is merely about 25%.It is thus clear that the weakness of circulation and storage link becomes the key factor that restriction China fruits and vegetables already develop.From another aspect, this has brought an opportunity of exploiting market and space for relevant capital.
The huge fresh-keeping industry market of China has attracted some overseas enterprises to get into.It is reported that Japan researches and develops multiple preservation technique and output equipment with China cooperation.Russia also repeatedly expresses willingness and aspect preservation technique, strengthens cooperation with China.The action of Italy preserving fruit and vegetable utilizing enterprise has more early just been set up representative office in China part city several years ago.They generally have advanced preservation technique, and the transport fruits of some enterprise production is packed special-purpose case even can fruit all be placed frozen state from links such as harvesting, storage, transportation and sale.
Recently, receive domestic corrugated paper supply and demand excessive influence to occur, begin to aim at area, China Shandong fruit packaging with the Japanese papermaking enterprise headed by the Oji Paper and use corrugated paper market, and decision is at Chinese production and selling corrugated paper.Japan paper is already studied and is thought; The food processing enterprises of China constantly increase the demand of corrugated paper packaging material; Abound with ground and Shandong is apple and pears, not only at the domestic mass selling of China, product also exports to Southeast Asia and Europe; The corrugated paper packaging material are well sold and in short supply, and having reached has the degree what how much need.
Therefore, it is extremely urgent to research and develop the better vegetable and fruit packaging material of a kind of fresh-keeping effect.
