Embodiment 1

[0015] The environment-friendly antibacterial fresh-keeping bag contains the following components by weight: 90 parts of polyethylene, 0.1 part of organic montmorillonite, 0.1 part of inorganic silver ion glass carrier antibacterial agent, 0.01 part of potassium permanganate, chelated lactate titanate 0.01 part; Among them, the weight of the inorganic silver ion glass carrier antibacterial agent in the fresh-keeping bag is 0.001%-5%, and polyethylene is high-density polyethylene. The extruder is extruded and granulated to become antibacterial polyethylene masterbatch, and its ratio is listed as antibacterial agent 0.001%-40%, polyethylene 60%-99.999%, the above antibacterial masterbatch and polyethylene, organic montmorillonite 0.1 0.1 part, 0.1 part of inorganic silver ion glass carrier antibacterial agent, 0.01 part of potassium permanganate, and chelating lactate titanate are blended in the mixer in proportion, and the mixed materials are added into the plastic extruder to m...

Embodiment 2

[0017] The environment-friendly antibacterial fresh-keeping bag comprises the following components by weight: 95 parts of low-density polyethylene, 10 parts of activated clay, 5 parts of antibacterial fine particles containing nano-silver, 5 parts of potassium dichromate, isopropyl tri(polyether group 2 parts of isooctyl pyrophosphoryloxy) titanate, and the antibacterial granule is made by the method comprising the following steps: (1) the stem pith of rush grass is cut into several pieces; (2) the stem pith of cutting is cut into several pieces; Immerse in the solution that contains nano-silver particles, so that the nano-silver particles are attached to the stem pith of the cut; (3) after attachment, wash the stem pith with hot water and cold water as the case may be; (4) attach the nano-silver particles Stem marrow is dry; And (5) the stem marrow containing nano-silver particle is ground into suitable size to make this nano-silver fine particle; The antibacterial fine partic...

Abstract

Environment-friendly antibacterial fresh-keeping bag comprises the following components in parts by weight: 90-99 parts of polyethylene, 0.1-10 parts of a breathable and water-tight supporting body, 0.1-10 parts of an antibacterial agent, 0.01-5 parts of an ethylene absorbing and decomposing agent and 0.01-5 parts of a coupling agent, wherein the breathable and water-tight supporting body is one of ultrafine inorganic powder organic montmorillonite and active clay; the ethylene absorbing and decomposing agent is one of pPotassium permanganate, potassium dichromate, potassium iodide and calcium peroxide; the antibacterial agent is an inorganic silver ion glass carrier antibacterial agent, a glass carrier silver ion antibacterial agent or a nanosilver-containing antibacterial fine grain; the coupling agent is one of chelated lactic titanate, isopropyltri(polyether isooctyl pyrophosphato)titanate, phosphomonoester, triisopropyl borate, gamma-chloropropyltrichlorosilane, gamma -hexyldiamino propyl triethoxysilane, vinylsilane and trichlorovinylsilane.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to an environment-friendly antibacterial fresh-keeping bag. It can be used to preserve general food such as vegetables, fruits, seafood, meat, etc. and agricultural products such as flowers and plants, and can increase the survival rate of aquaculture animals. Background technique [0002] At present, there are ordinary fresh-keeping bags in the domestic market, which do not contain antibacterial agents, especially glass carrier silver ion antibacterial agents. Foreign developed countries have entered the antibacterial era in the 1980s. In recent years, the domestic antibacterial industry has just started to develop, but the technology is mixed, such as: poor antibacterial effect, easy to change color and other problems that need to be improved. With the improvement of living standards, people's requirements for living standards, quality and environment are getting hig...
