There are various types of egg tray additives, which are mainly selected based on the required functions and characteristics of the egg tray. Here are some common types of egg tray additives and their brief explanations:
1. Waterproof additives
Function: Improve the waterproof performance of the egg tray, prevent moisture infiltration, and protect the eggs inside the egg tray from moisture.
Example: wax lotion, wax powder, polyolefin lotion, etc. These additives can form a waterproof film on the surface of the egg tray, enhancing its waterproof effect.
Suppliers: such as Tianshi Wax Powder, Dongguan San'er Paper Technology Co., Ltd., etc., provide a variety of waterproof additive products.
2. Anti mold and fresh-keeping additives
Function: By adding ingredients with antibacterial and anti mold functions, the preservation time of eggs in the egg tray is extended and bacterial growth is reduced.
Examples: Nano zinc oxide, nano titanium dioxide, chitosan, etc. These ingredients have broad-spectrum antibacterial properties and can effectively inhibit the growth of mold and bacteria.
Innovative applications: Some new additives also combine multiple components, such as nano zinc oxide, nano titanium dioxide, lime powder, sodium bicarbonate, chitosan, taurine, citric acid, etc., to provide a more comprehensive anti mold and preservation effect.
3. Enhancers and hardeners
Function: Enhance the mechanical strength of the egg tray, making it more durable and able to withstand various pressures during transportation and storage.
Example: Paper holder hardener, reinforcing fiber, etc. These additives can improve the fiber structure of egg trays and enhance their compressive and flexural properties.
4. Moisture proof agent
Function: Reduce the moisture absorption of egg trays and prevent deformation or damage caused by excessive moisture absorption in humid environments.
Example: Paper moisture-proof agent, papermaking moisture-proof agent enhancer, etc. These additives can form a moisture-proof layer inside the egg tray, effectively blocking the invasion of moisture.
5. Other additives
Whitening agent: used to improve the appearance and color of egg trays, making them whiter and more beautiful.
Defoamer: It is used to eliminate foam and improve production efficiency and product quality during the production of egg custard.
Deodorizer: Used to remove odors generated during the production process of egg trays and improve the production environment.
It should be noted that the amount and usage of different additives need to be determined according to the specific product formula and production process. At the same time, when selecting additives, factors such as safety, environmental friendliness, and cost-effectiveness should also be considered.
In summary, there are various types of egg tray additives, each with its specific functions and application scenarios. In actual production, appropriate additives should be selected based on the specific needs and process requirements of the egg tray.
