What are the specific anti mildew treatment processes for gift boxes?

First, the paper should be kept clean and hygienic. The materials in the turnover box in the workshop should be kept clean and tidy, and it is recommended that the turnover box of the raw materials not used on the day should be covered with cloth or plastic film to block the dust, and the semi-finished products produced should not be placed on the ground, and the pallet or material rack should be isolated and placed.

Second, control the humidity of packaging materials such as paper materials and cartons below 12 degrees, and use plastic film to wrap materials that are not used for a long time to block dust and moisture (the customs acceptance standard is below 12%, and there is a risk of mold if it exceeds 12%).

Third, glue, especially environmentally friendly animal glue, must be added to a certain proportion of glue antifungal agent in the animal glue before use, to solve the problem of mildew in the gift box caused by mounting glue.

Fourth, place an appropriate amount of biochemical desiccant in the gift box packaging carton, and the inner box and outer box of the packaged finished product should be kept clean and tidy, and the biochemical desiccant can not only adsorb water and grow 3 times the weight. Or put a few pieces of anti-mold tablets. It can trigger the anti-mold ingredient to kill mold and inhibit the growth of mold in a relatively confined space, so as to achieve the effect of mold prevention.

Remarks: The door of the toilet in the gift box production workshop should be kept clean, and there should be no water seepage, and the goods can not be stacked next to the toilet, so as not to make the product mildew due to moisture.

Anti-mold packaging method:

1 There are two types of sealed packaging and anti-mold packaging methods, one is sealed packaging and the other is unsealed packaging.

There are four ways to seal a package.

Vacuuming displaces inert gases.

Sealed package. This method uses a hermetically sealed packaging structure in which the inert gas is evacuated in the container and replaced. In a microenvironment dominated by inert gases, the product will not be infected by mold and will not germinate. This method can be used as a packaging measure for the finger sealing of trousers.

Dry air seal packaging. Choose all kinds of containers or composite materials with good air tightness and low moisture permeability for sealed packaging. Place desiccant in an airtight container.

and humidity indicator paper to control the relative humidity in the packaging container.

Less than or equal to 60%.

Deoxygenation and sequestration. Choose composite materials or other sealed containers with good air tightness, low moisture permeability and low oxygen permeability for sealed packaging. Place an appropriate amount of oxygen scavenger inside an airtight packaging container.

and oxygen indicators. The oxygen scavenger can remove the oxygen concentration in the packaging container to the following He Chunbu, and realize the oxygen removal and sealing to prevent the growth of mold in the product.

Volatility. Antifungal agent anti-mildew. According to the specific situation of the product, a volatile antifungal agent with antibacterial bacteria is placed in the sealed package Zen spike container for anti-mildew packaging.

2 Unsealed packaging.

There are two ways to do non-sealed packaging.

The product is effectively treated with anti-mildew. For products and parts that are prone to mildew, they should be effectively mold-proof, and then packaged with anti-mold paper.

Open the ventilation window of the packing box. For products with low susceptibility to mold or low water absorption, and the volume of the packaging box is large, ventilation windows can be opened on the upper part of both ends of the packaging box to control the moisture content in the packaging box.

The function of the ventilation window is to prevent and reduce the condensation on the product due to temperature rise, resulting in mold growth of the product. Generally, products that have been effectively treated with anti-mold or products that are less sensitive to mold can be packaged in non-sealed packaging.

In life, we encounter the situation of moldy gift boxes, and here is a brief summary of some of the reasons for the moldy gift boxes:

1.The humidity of the warehouse exceeds the standard, and the humid air causes the color box to be damp;

2.The jelly glue and animal glue used in laminating paper contain naturally rich protein and starch, which have become the favorite nutrients of mold, which increases the risk of mold in gift boxes;

3.The paper material itself has high humidity, and when it exceeds 12%, there is a potential risk of mildew. I'm here to talk about some anti-mold advice when producing gift boxes:

1. The paper material should be kept clean and hygienic. The materials in the turnover box in the workshop should be kept clean and tidy, and it is recommended that the turnover box of raw materials not used on the day should be covered with cloth or plastic film to block the dust, and the semi-finished products produced should not be placed directly on the ground, and placed in isolation with pallets or material racks.

2. Use a humidity tester to measure the humidity of materials, and control the humidity of paper, cartons, bamboo and other materials within 12% (the customs acceptance standard is below 12%, and there is a risk of mildew if it exceeds 12%).

3. Jelly glue (animal glue), 1-2% ASD-SX glue antifungal agent must be added to it before use to cut off the food chain of mold growth and make it unable to grow and multiply.

Anti-mildew measures: First, the paper should be kept clean and hygienic. It is recommended that the materials not used on the day be sealed to prevent dust, and the semi-finished products produced should not be placed on the ground to avoid moisture and mildew.

Second, control the humidity of the material below 12, and pay attention to moisture-proof, moisture-proof, dust-proof and other materials that have not been used for a long time (the customs acceptance standard is below 12%, and there is a risk of mildew if it exceeds 12%).

Third, the glue used in the gift box can be added with an appropriate amount of glue antifungal agent before use, which fundamentally prevents the problem of mildew in the gift box.

Fourth, place an appropriate amount of desiccant in the gift box packaging carton, and the packaged products should be kept clean and tidy; or put a piece of mold sheet; Create a mold-proof space.

Ultraviolet sterilization, keep relatively dry, not overstocked

Causes of mold:

First, due to the long-term environmental humidity exceeding the standard, the air is humid, resulting in the color gift box is damp and moldy;

Second, there is a large amount of starch and protein in the powder glue (jelly glue) used in the production, which are rich nutrients needed for mold growth, so there is a high risk of mold in the box;

Third, the humidity of the paper material of the gift box itself exceeds 12%, and there is a risk of mold;

Anti-mold packaging is packaging that takes certain protective measures to prevent mildew of packaging and contents. In addition to moisture-proof measures, it also needs to carry out anti-mildew treatment on the packaging materials. Anti-mold packaging must be based on the physiological characteristics of microorganisms, improve the environmental conditions such as production and control packaging and storage, and achieve the purpose of inhibiting mold growth.

First, we should try to choose materials that are resistant to mildew and have a compact structure, such as aluminum foil, glass and high-density polyethylene plastics, polypropylene plastics, polyester plastics and their composite films, etc., which have the properties that are not easy for microorganisms to pass through and have good anti-mildew performance. Second, the container is required to have good sealing, because sealed packaging is an important measure to prevent moisture, such as the use of blister, vacuum and inflation and other tightly closed packaging, which can not only block the invasion of external moisture into the packaging, but also inhibit the growth and reproduction of mold. Thirdly, the method of anti-mildew can be added in the production of packaging materials, or the packaging container can be soaked with antifungal agent and sprayed with an appropriate amount of antifungal agent in the packaging container, such as carbendazim (BCM), chlorothalonil, salicylyl deaniline, fungus scoop, sodium pentachlorophenol, etc., for the anti-mildew of packaging materials such as paper and paper products, leather, cotton and linen fabrics, wood, etc.

Fourth, it can also be treated with vapor phase mildew prevention, mainly paraformaldehyde, nitrogen-filled packaging, and carbon-dioxide-filled packaging, which also has good effects. [1]
