preparation example Construction

[0031] figure 1 The method flow chart of the preparation method of the degradable antibacterial fresh-keeping film product provided by the embodiment of the present invention. The application of the preparation method can provide a packaging material with high efficiency, broad spectrum, long-term effect and safe antibacterial performance, so that it can reduce the amount of antiseptic additives used and increase the storage time. Such as figure 1 Shown, described preparation method comprises the steps:

[0032] 110. According to the set mass percentage, weigh and mix various raw materials respectively.

[0033] In this embodiment, the raw materials include environmentally friendly substrates, C3N4 and other non-metallic photocatalytic materials, antioxidants, lubricants and additives. The mass percentage ranges set for each raw material are: 48%-75% of environmentally friendly substrates, 1%-9% of C3N4 and other non-metallic photocatalytic materials, 0.1%-1% of antioxidant...

Embodiment 1

[0058] 1) Take raw materials by the following mass percentages:

[0059]

[0060]

[0061] 2) Adding the weighed raw materials into an injection molding machine for mixing, melting and plasticizing into a melt mixture.

[0062] 3) Injecting the melt mixture into a molding mold to form a hollow green body.

[0063] 4) Passing high-pressure gas into the hollow embryo body to make it expand and shape in the forming mold to prepare nano-antibacterial packaging products.

[0064] The antibacterial packaging product of the embodiment of the present invention has excellent antibacterial performance, and can realize complete biodegradation, and has no pollution to the environment. Food preservation film, vegetable preservation box, disposable lunch box, agricultural mulch film, medicine storage box, etc.

Embodiment 2

[0066] 1) Take raw materials by the following mass percentages:

[0067]

[0068] 2) Adding the weighed raw materials into an injection molding machine for mixing, melting and plasticizing into a melt mixture.

[0069] 3) Injecting the melt mixture into a molding mold to form a hollow preform.

[0070] 4) Passing high-pressure gas into the hollow preform to make it expand and shape in the forming mold to prepare nano antibacterial packaging products.

[0071] The packaging product of the embodiment of the present invention has antibacterial effect and continuous antibacterial effect. It also has excellent antibacterial effect not only under the condition of light, but also under the condition of no light. In fields such as medicine, it is specifically applicable to fruit fresh-keeping bags / films, food fresh-keeping films, vegetable fresh-keeping boxes, disposable lunch boxes, agricultural mulching films, medicine storage boxes, etc.

Abstract

The invention relates to the technical field of packaging materials, in particular to a degradable antibacterial preservative film product and a preparation method thereof. The degradable antibacterial preservative film product is prepared from the following raw materials in percentage by mass: 45%-75% of an environment-friendly base material, 1%-10%% of a nonmetal photocatalytic material, 0.1%-1%of an anti-oxidant, 2%-9% of a lubricant and 10%-40% of auxiliaries. The degradable antibacterial preservative film product has efficient, broad-spectrum, long-acting and safe antibacterial properties, and facilitates reduction of the use of additives such as the preservative and the like in food and drugs, so that the food and drugs can be stored for a longer time and can be transported further.The degradable antibacterial preservative film product is an environmentally-friendly type material, can be quickly decomposed in a natural environment, is beneficial for ecological environmental protection, reduces pollution and damages to environment, has a wide application prospect, and is widely applied to the packaging and freshness-retaining fields such as food, drugs, fruits and vegetables, fresh food and the like.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a degradable antibacterial fresh-keeping film product and a preparation method thereof. Background technique [0002] With the continuous improvement of national living standards, consumers are paying more and more attention to food safety issues, especially the hygiene and safety of packaging such as food and medicine. [0003] Because pharmaceutical and food packaging involves many links such as production, storage, transportation, and use. Therefore, the packaging of food or medicine usually needs to go through a relatively long period of time, and it is easy to breed bacteria such as Escherichia coli and Staphylococcus aureus inside the packaging, leading to health and safety accidents of food or medicine. [0004] In the process of realizing the present invention, the applicant found the following problems in the prior art: In order to prolong the safe use perio...
