How do disposable cornstarch tableware form?

 Disposable cornstarch tableware is a kind of disposable tableware formed by foaming starch. Hengfeng is a professional disposable cornstarch tableware manufacturer in china, today, Let us introduce the disposable corn starch tableware is how to shape,It is made of 86-93 parts by weight of modified cornstarch, 0.8-1.2 parts by weight of release agent zinc stearate, and 0.2-0.4 parts by weight The accelerant potassium sorbate, 1.5-2 parts by weight of thickener sodium polyacrylate, 45-53 parts by weight of stabilizer, and several parts by weight of water are mixed and stirred to obtain the mixture, which is obtained by hot pressing.

The stabilizer is made by mixing wood pulp fiber and modified chaff in a ratio of 1:1.5-2.

Modified corn starch is a mixture of corn starch, tea polyphenols and water in a mass ratio of 1:0.22-0.28:1.5-1.8, ultrasonic treatment at 35KHz for 35-40min, suction filtration, and concentration of the filtrate to 1% of the volume of the filtrate. /2, the modified solution is obtained for use, the filter residue is dried to a moisture content of 6%-7%, and the modified corn starch is obtained by crushing, wherein the water temperature is 30 degrees Celsius.

The stabilizer is to crush the chaff through an 80-100 mesh sieve, then put it into the modified liquid, heat it to 30 degrees Celsius in a water bath, boil it into an extract with a water content of 45%-50%, and then add wood pulp fiber , Just stir.

The production method of disposable corn starch:

Its production method is to mix modified corn starch, zinc stearate, potassium sorbate, sodium polyacrylate, stabilizer according to the proportions, add water to prepare a paste-like solid with a water content of 9-13%, and put it into the mold as required Medium, hot press molding is sufficient.

The hot pressing temperature is 120-150 degrees Celsius, and the pressure is 0.15-0.2MPa.

Disposable cornstarch tableware has high starch content, which greatly reduces production costs. Cornstarch is used as the main raw material, modified with tea polyphenols, and assisted by a variety of functional additives to make foaming lunch boxes. The foamed lunch box will not produce any toxic components after being heated, and can be converted into easily degradable substances under natural conditions, is safe and environmentally friendly, and can effectively protect the environment.

The toughness of wood pulp fibers can effectively support the plasticity of tableware. The use of tea polyphenols to modify corn starch and the strong antioxidant properties of tea polyphenols make the tableware made with a longer shelf life. Soak the chaff in Among the remaining modified liquid, one is to effectively recover tea polyphenols and starch solutions, and the other is to use the detoxification and anti-radiation effects of tea polyphenols to effectively prevent radioactive substances, making the tableware made more safe and hygienic.

Potassium sorbate can effectively inhibit the activity of molds, yeasts and aerobic bacteria. It can also prevent the growth and reproduction of harmful microorganisms such as endotoxin, staphylococcus, and Salmonella. Its growth inhibition effect is stronger than its bactericidal effect. Disposable cornstarch tableware will not produce mildew after long-term storage.
