The production process of cornstarch material tray

1. Raw material preparation:
The first is the main raw material: Naturally, the selection of high quality corn starch, corn starch comes from nature, after heavy screening, we can ensure its purity and no impurities.
Then there are auxiliary materials: such as glycerin, white vinegar, a small amount of plastic additives (such as polyvinyl alcohol, etc.), which are used to enhance toughness and water resistance, otherwise simple cornstarch can not be successfully bonded into the tray, and the waterproof and oil-proof performance can also be guaranteed. So adding a small amount of plastic is the best choice, but the proportion of plastic is very low, so that you can maintain the environmental protection of the produced tray).
Others: water, mold (for custom production), etc.
2. Mixing and processing:
This is the key step in making the raw material for corn starch. First of all, our staff will mix cornstarch, glycerin, white vinegar and a small amount of plastic additives in a certain proportion (usually starch is the majority, plastic additives are only trace). The proportion of this mixture will be adjusted several times according to the requirements and performance of the specific product, in order to ensure that the performance and quality of the product is high. This process will also try to maintain a high proportion of starch and a low proportion of plastic content to reflect its environmental characteristics.
During the mixing process, add the right amount of water to adjust the viscosity of the mixture, and stir thoroughly to ensure that all ingredients are evenly mixed.
3. Molding and curing:
This step is where the product is produced. The mixture is poured into a specific mold, the shape of which determines the shape and size of the final tray.

The mixture in the mold is placed in a heated environment (such as an oven or hot press), and the mixture is cured by heat. During heating, the starch in the mixture will gelatinize, while glycerin and plastic additives will enhance the toughness and stability of the material.
Curing time depends on the material formulation and heating conditions, and it usually takes some time to ensure that the tray is fully hardened and set.
4. Demoulding and follow-up treatment:
After curing is complete, the tray is removed from the mold and the necessary trimming and cleaning is carried out.
According to the need, the tray can be surface treatment, such as coating waterproof layer or antibacterial agent, to enhance its performance and health safety.
5. Quality inspection and packaging:
Quality inspection of finished pallets, including appearance inspection, load-bearing test, waterproof test, etc., to ensure that they meet the standards used in supermarkets.
Qualified pallets will be packed into warehouses and prepared for sale to customers such as supermarkets.
About proportionality and environmental protection
Ratio: As specific formulations may vary by manufacturer and product requirements, an exact ratio cannot be given. But in general, cornstarch accounts for the vast majority (perhaps up to more than 90%), while plastic additives are only trace amounts.
Environmental protection: The biggest advantage of cornstarch trays is their environmental protection. They are biodegradable and reduce environmental pollution. At the same time, due to the use of renewable resources (maize), the recycling of resources is also promoted.
In short, the production process of cornstarch pallets combines the advantages of natural renewable resources and a small amount of plastic additives, which not only ensures the physical properties and durability of the product, but also reflects the concept of environmental protection and sustainable development.and cornstrach material is safe and great.
