Far infrared insect-proof and waterproof refreshing fruit packaging material produced by utilizing yellow soil and manufacturing method thereof

Abstract

The invention discloses a method for manufacturing a fruit packaging material which is insect-proof and can prevent water seepage, promote fruit growth, improve health of fruit nutrition and is environmentally-friendly and the fruit packaging material prepared by using the method. The method comprises the following steps: uniformly mixing and stirring 10-29wt% of yellow soil, 10-39wt% of edible corn starch, 1-10wt% of illite and 50-69wt% of water, wherein the total weight percent is 100%; heating and boiling for 10-20 minutes at the temperature of 100-120 DEG C to get a yellow soil mixed solution; and applying a coating device to coat 10-20g of the yellow soil mixed solution per square meter on one side of raw paper and coat waterproof glue on the other side, and drying for getting the fruit packaging material. A bag manufactured by using the fruit packaging material has the effects of protecting fruits, preventing pests and birds from harming the fruits, promoting the fruit growth and improving the fruit quality. By using a packaging box manufactured by the fruit packaging material for storing the fruits, the shelf life can be prolonged, the water volatilization can be prevented, and the sweetness can be maintained.

Description

technical field [0001] The invention relates to a fruit packaging material and a manufacturing method thereof, in particular to a far-infrared insect-proof, waterproof, and fresh-keeping fruit packaging material made of loess and a manufacturing method thereof. Background technique [0002] Fruits are rich in minerals, vitamins, essential amino acids, a variety of organic acids and dietary fiber, which have important nutritional value for the growth of the human body and the maintenance of the health of the body. Along with the continuous improvement of people's living standards, fresh, pest-free and non-toxic fruits are more and more favored by consumers. However, even if the pesticides approved by the state such as dimethoate, trichlorfon, and dichlorvos are used as pesticides for fruits and vegetables, certain toxins still remain on the harvested fruits and vegetables. [0003] The fruit bagging technology that has emerged in recent years has solved the above problems to...

Problems solved by technology

However, there are still some deficiencies. The biggest problem is that the "water vapor" contradiction must be solved, that is, the rainwater and pesticides outside the bag cannot enter the bag, and the physiological water and condensed water of the fruit in the bag must be excluded from the bag, otherwise the temperature inside the bag will The difference between humidity and humidity is too high, which will affect the quality of fruit

At present, the existing fruit bags are divided into two kinds of materials, one, paper material, the fruit bags made of this material have good air permeability, and the temperature and humidity difference in the bag are relatively balanced, but it cannot prevent rainwater from entering the fruit bag Inside, a large amount of fruit rust is formed on the surface of the fruit, which affects the growth quality and appearance of the fruit, and directly leads to a reduction in economic value; 2. Polymer film material, the fruit bag made of this material is very waterproof, but the air permeability is insufficient. A large amount of physiological water and condensed water produced during fruit growth are not easy to volatilize, the ratio of temperature and humidity inside the bag and outside the bag is seriously unbalanced, the temperature inside the bag is high, sunburn is prone to occur, and the grown fruit has poor flesh quality and taste not tasty
