Sterile composite roll film for seed storage and production process thereof

Abstract

The invention belongs to the technical field of composite films and production processes thereof, and particularly relates to a sterile composite roll film for seed storage and a production process thereof. The invention relates to a sterile composite roll film for seed storage. The sterile composite roll film for seed storage consists of a surface layer, an inner layer and a core layer positioned between the surface layer and the inner layer. The surface layer, the inner layer and the core layer located between the surface layer and the inner layer are bonded through a solvent-free composite technology to obtain the sterile composite roll film for seed storage. The inner layer and the outer layer both have a high-ultraviolet-resistance effect, the core layer is mainly composed of a three-layer co-extruded nylon water bag film, and meanwhile the surface of a PET film and the surface of a nano composite film are both coated with polyvinyl alcohol. Therefore, the sterile composite roll film for seed storage, which is high in toughness, strong in antibacterial activity and capable of inhibiting seed germination, is achieved, and meanwhile, the production process is relatively simple, and the process cost and the efficiency are both superior to those of production processes of other products.

Description

technical field [0001] The invention belongs to the technical field of composite film and its production process, in particular to an aseptic composite roll film for seed storage and its production process. Background technique [0002] When storing seeds, it is necessary to inhibit the germination of the seeds, and at the same time, the seeds need to be stored under sterile conditions. The existing composite roll film has defects in toughness, antibacterial properties, and its production process, so it is urgent It is necessary to develop a sterile composite roll film for seed storage with high toughness, strong bacteriostasis, and ability to inhibit seed germination, and a production process that reduces production costs. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to overcome the existing defects in toughness, bacteriostasis, and production process of the existing composite roll film, the present invention provides an asepti...
