specific Embodiment approach 1

[0012] It is made of the following ingredients in parts by weight: 76 parts of high-density polyethylene HDPE, 5 parts of low-density polyethylene LDPE, 15 parts of linear low-density polyethylene LLDPE, 3 parts of nano-silver particles, fully stirred by a mixer, blown Film, slitting and heat sealing are packaged, the temperature of each heating zone is controlled at 190-240°C in film blowing, and the heat sealing temperature is controlled at 210-250°C in slitting and heat sealing. Nano silver can inhibit Escherichia coli and Staphylococcus aureus, is Because nano-silver can release silver ions, denature the protein in bacterial cells and affect its metabolism, so as to achieve the effect of sterilization. When these bacteria die, silver ions return to the nano-silver, so the bactericidal function of nano-silver is persistent.

specific Embodiment approach 2

[0013] A nano-preservation product with antibacterial function and a preparation method thereof of the present invention are made of the following components in parts by weight: 76 parts of high-density polyethylene HDPE, 5 parts of low-density polyethylene LDPE, and 15 parts of linear low-density polyethylene LLDPE Parts, 2.5 parts of nano-silver particles, 0.5 parts of modified nano-graphene oxide, fully stirred by the mixer, blown film, cut and heat-sealed, then packaged, the temperature of each heating zone in the blown film is controlled at 190-240 ° C, cut and heat-sealed The antibacterial agent obtained by compounding the modified nano-silver and graphene oxide material not only has excellent antibacterial performance, but also the graphene oxide material is a single layer that is highly densely packed into a two-dimensional honeycomb structure. Carbon atoms, single-layer graphene has a large specific surface area and porosity, and can be used as a carrier to support nan...

Abstract

The technical problem mainly solved by the invention is to provide a nano fresh-keeping product with an antibacterial function and a preparation method of the nano fresh-keeping product. The nano fresh-keeping product comprises 76 parts of high-density polyethylene HDPE, 5 parts of low-density polyethylene LDPE, 15 parts of linear low-density polyethylene LLDPE and 3 parts of nano silver particles. The raw materials are fully and uniformly stirred in a material stirring machine, and then film blowing, cutting, heat lamination and packaging are carried out. According to the nano-antibacterial fresh-keeping bag, the antibacterial effect of the fresh-keeping bag material can be effectively improved by adding nano-silver particles or graphene oxide with an antibacterial effect, so that long-acting antibacterial fresh-keeping of fruits and vegetables can be realized.

Description

technical field [0001] The invention relates to the field of disposable daily necessities, more specifically a nano fresh-keeping product with antibacterial function and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the freshness of fresh fruits and vegetables are getting higher and higher, and the pursuit of product safety and quality is also increasing. During the storage of fruits and vegetables, not only the respiration will cause the loss of nutrients, but also improper storage will cause the decay of fruits and vegetables. Among them, the action of microorganisms such as bacteria and mold is also an important factor affecting the preservation of fruits and vegetables, which greatly shortens the shelf life of fruits and vegetables. Therefore, it is necessary to develop excellent preservation technologies and materials for preservation of fruits and vegetables. [0003] At present, the...
