Abstract
The utility model relates to a rice fresh-keeping bag. The rice fresh-keeping bag of the utility model is achieved by the following technical scheme that the rice fresh-keeping bag comprises a fresh-keeping inner core formed by bamboo charcoal particles and a package bag wrapping the fresh-keeping inner core. The rice fresh-keeping bag of the utility model can effectively prolong the fresh-keeping time and overcome the defects of a background technology.
Description
Technical field
The utility model relates to a kind of fresh-keeping bag.
Background technology
At present, China is the not enough 400KG of grain yearly output per capita, a little less than world average level, well below the U.S., Canada, Australian 1500KG per capita; And the grain yield of China is very unstable, and frequent natural calamity takes place.
People often are stored in rice in the bigger container in actual life, and these rice such as about one month time, then can bear moth, and become damp easily at short notice if do not dispose, and cause mouldyly, have wasted grain resource greatly.
The utility model content
The purpose of this utility model provides a kind of preserving rice bag, and the freshness date that effectively prolongs rice has overcome disadvantages of background technology.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of preserving rice bag, it comprises fresh-keeping inner core that is formed by bamboo charcoal particle and the packaging bag of wrapping up fresh-keeping inner core.
As of the present utility model preferred, the particle diameter of described bamboo charcoal particle is 2mm to 5mm.
As of the present utility model preferred, every 200cm
2Packaging bag in the 100g bamboo charcoal particle is housed.
As of the present utility model preferred, the internal layer of described packaging bag is a nonwoven layer, skin is the grease-proof and waterproof ply of paper, nonwoven layer one surface recombination is provided with the ethylene-vinyl acetate leaching membrane layer, be equipped with pore on nonwoven layer and the ethylene-vinyl acetate leaching membrane layer, ethylene-vinyl acetate leaching membrane layer one surface is gluing compound by heat posted and grease-proof and waterproof ply of paper.
As of the present utility model preferred, described nonwoven layer adopts 50g/ m
2To 90g/m
2Nonwoven fabrics constitute.
As of the present utility model preferred, described grease-proof and waterproof ply of paper adopts 50g/m
2To 90g/m
2Grease-proof and waterproof paper constitute.
As of the present utility model preferred, described ethylene-vinyl acetate leaching membrane layer thickness is 15 to 40 μ m.
In sum, the utlity model has following beneficial effect:
1, bamboo charcoal is a natural product, and is nontoxic, tasteless, have no side effect;
2, the bamboo charcoal molecular structure is hexagon, and quality is hard, and countless holes is arranged itself, can absorb various suspended solids in the air effectively, so adsorption affinity is strong, and has the decomposition peculiar smell, deodorizing and damp-proof function;
3, packaging bag of the present utility model is novel, unique, has grease-proof and waterproof function and air permeability and good, toughness and is difficult for breaking, and can prevent effectively that packaging bag is by the generation of phenomenons such as tearing by mistake.
Description of drawings
Fig. 1 is embodiment 1 a package construction scheme drawing;
Among the figure, 2, packaging bag, 21, nonwoven layer, 23, the grease-proof and waterproof ply of paper, 22, the ethylene-vinyl acetate leaching membrane layer, 3, pore.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification sheets, but as long as all are subjected to the protection of patent law in claim scope of the present utility model.
