Storage mildew-proof and moth-proof packaging hemp cloth and preparation method thereof

Abstract

The invention provides storage mildew-proof and moth-proof packaging hemp cloth and a preparation method thereof. The hemp cloth comprises green harmless storage protective agent and is prepared by taking common packaging hemp cloth as a material and adding 0.01-10wt% of storage protective agent. The preparation method comprises the following steps of: dissolving the storage protective agent in a solvent to prepare a solution, then impregnating the hemp cloth in the protective agent solution, removing the solution after the hemp cloth sufficiently absorbs the solution, and drying; or dissolving the storage protective agent in the solvent, then uniformly spraying the protective agent solution on the hemp cloth and drying the hemp cloth after the hemp cloth sufficiently absorbs the protective agent solution to prepare the storage mildew-proof and moth-proof packaging hemp cloth. The storage hemp cloth is used for packaging tobaccos or crops, can realize the whole process dynamic and real-time protection of the tobaccos, the crops and the like in purchase, transport and storage processes, protect products from mildew and moths, effectively prevent the mildew and the moths from spreading between bags and prevent the tobaccos, the crops and the like which are soaked by rain water from mildewing. Besides, the invention has an important function for reducing environment pollution and hidden safety danger which are caused by common technologies.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a mildew-proof and insect-proof packaging sackcloth for storage and a preparation method thereof. Background technique [0002] Tobacco leaves are an important raw material for the tobacco industry. Raw tobacco is prone to mildew and insect damage during the process of purchase, storage, transportation and storage. Not only the smoking quality of tobacco leaves, but also mycotoxins can be produced, which will seriously affect human health. In the production of tobacco leaves, the losses caused by mildew and insect damage are quite astonishing, reaching more than 3% of the total amount of tobacco products, seriously affecting the quality and economic benefits of tobacco leaves and cigarettes. [0003] At present, the technology of the mildew-proof and insect-proof methods for tobacco leaf storage researched and developed both at home and abroad mainly includes: 1. Cont...

Problems solved by technology

The antimicrobial cloth that this inventive method makes is mainly used in hotel and household antifungal and antibacterial use, and what mainly used in manufacture is chemical antifungal drug (some of which are forbidden to use in grain or food); in order to meet the requirement of repeated cleaning, the The method uses a large number of flammable additive chemical hot melt adhesives, such as polyethylene-vinyl acetate hot melt adhesive, ethylene-acrylate hot melt adhesive, polyurethane hot melt adhesive, polyester hot melt adhesive, polyamide hot melt adhesive Therefore, the antimicrobial cloth produced by this method cannot be used for storage and packaging of tobacco and grain, otherwise it will cause pollution and safety hazards in use; at the same time, hot melt adhesive will affect the air permeability of the cloth and cannot be used for raw materials. Cigarette packaging, otherwise it will cause more serious mildew due to poor moisture distribution in the cigarette package

In addition, the antimicrobial cloth produced by this method cannot be used for insect control
