Green double-protection fresh-keeping bag for finished product of grain

Abstract

The invention relates to a finished grain green double-protection freshness keeping bag, which is characterized in that a manufacturing method of the freshness keeping bag comprises that the surface of common single-layer kraft paper is coated with 58-degree paraffin wax under the condition of between 70 and 80 DEG C, and the coating quantity is between 3 and 5 gram / meter<2>, wherein under a molten state with the temperature of between 70 and 80 DEG C of paraffin wax liquid, a certain quantity of insect-resist agent Chinese pepper oil, fenitrothion and anti-mildew agent thiabendazole are added sequentially. The coated kraft paper is made into the freshness keeping bag. When the finished grain green double-protection freshness keeping bag is used for storing grains, the aims of insect prevention and mildew prevention can be achieved. The finished grain green double-protection freshness keeping bag has the advantages of low cost, easy processing, good effect and no pollution.

Description

technical field [0001] The invention belongs to fresh-keeping materials for agricultural products, in particular to a green double-proof fresh-keeping bag for finished grain. Background technique [0002] China is the world's largest rice production and marketing country, and rice production generally accounts for 45% of the total grain output, and the annual supply basically remains at a relatively high level of 180 to 200 million tons. It is estimated that my country's rice loses about 1 billion kg every year due to factors such as aging, moisture absorption, mildew, insect damage, and rodent damage. During the grain storage period, due to the change of physiological and biochemical characteristics, the quality of the grain deteriorates, which brings great economic losses. A green grain fresh-keeping bag that prevents mold and insects for finished grain is developed, which not only conforms to my country's grain preservation policy, but also promotes grain preservation.
