Abstract

The invention relates to the field of seed storage and packaging, and provides a manufacturing method of an antibacterial packaging material for seed storage, and the antibacterial packaging material comprises an antimony-doped tin oxide nanoparticle material and an indium-doped tin oxide nanoparticle material; the manufacturing method of the antibacterial packaging material comprises the following manufacturing steps: S1, preparing an antimony-doped tin oxide nanoparticle material; s2, preparing an indium-doped tin oxide nano particle material; s3, film blowing: three-layer co-extrusion is adopted, a film body is made of a PE material, and antimony-doped tin oxide and indium-doped tin oxide nanoparticles are added into the plastic film body; growth of mould around seeds can be remarkably inhibited, and the antibacterial time is long. Meanwhile, the used materials are low in raw material cost, simple in process, easy to put into industrial production and non-toxic, and use of nano-silver antibacterial materials with potential safety risks and very high cost is avoided.

Description

technical field [0001] The invention relates to the field of storage packaging, in particular to a method for making an antibacterial packaging material for seed storage. Background technique [0002] Seeds are a vital part of the planting process, and the quality of seeds directly determines the yield of crops. However, during the long-distance transportation of seeds, a large number of microorganisms may grow due to low temperature, humid air, direct exposure to air, etc., resulting in mildew and lower quality of seeds. If some seeds are infected with mold, other healthy seeds in the bag will also be affected, resulting in reduced germination rate and reduced harvest. A large number of infected agricultural by-products will also cause harm to people's health. Therefore, effectively delaying the quality reduction of seeds during storage and prolonging the shelf life has become an urgent problem that should be solved at present. [0003] Seeds are usually stored in plasti...
