What is Cornstarch Tableware
Corn starch tableware is a biodegradable product. It uses corn starch as the main raw material and is processed by high-tech production technology. It can be degraded by itself under natural conditions, avoiding environmental pollution and saving non-renewable resources such as petroleum. It has been tested by the national authority According to the department’s inspection, all the hygienic physical and chemical indicators have reached the national standard. It is an ideal substitute for the widely used but controversial “disinfected tableware” in the catering market.
Advantages of disposable degradable tableware;
No pollution to the human body Because it is refined from corn starch and other environmentally friendly materials, it does not contain harmful substances to the human body, so it can be used safely for a long time.
Zero Pollution The product is buried in the soil, and at a suitable temperature, it can be degraded to form carbon dioxide and water after 90 days, without polluting the soil and air.
Saving resources Corn starch is a renewable resource that is inexhaustible and inexhaustible, while paper tableware and plastic tableware require a lot of wood and petrochemical products. Using corn starch as raw material can save a lot of oil and forest resources.
High quality The product is densely woven, water-resistant, oil-resistant, impermeable, and has good high-temperature and low-temperature resistance, suitable for refrigerator freezing, cold storage, fresh food, microwave heating, etc.
Distinguish between true and false cornstarch tableware
1. The distinction is very simple and can be divided into three aspects:
a. Visual observation means that starch-based utensils are matt-type products with some light yellow or milky white. Non-starch products are dark or bluish white in color.
b. Odor identification means that after similar products rub against each other to generate heat, starch products have a light corn paste smell or plant fragrance, and other products have a plastic smell.
c. Combustion identification means that the two types of products are respectively burning red flames for starch products and blue flames for other products. The ash after burning is crushed by hand, and the black powder is starch products, while the lighter powder powder is other products.
2. The main components are carrier resin, corn starch, coupling agent, sizing agent, phase solvent and other low molecular weight components.
3. Floating objects may be caused by two situations
a. The amount of lubricant added is too large and the residue is left on the surface of the product due to incomplete devolatilization during processing.
b. Inorganic substances such as talcum powder. It is formed by adding too much heavy calcium.
The difference between cornstarch tableware and fully degradable tableware
The main differences between completely degradable tableware, i.e. biodegradable tableware, and cornstarch tableware are as follows:
1. Different production principles
1. Corn starch tableware: Corn starch is used as the main raw material and processed by high-tech production technology, which can be degraded by itself under natural conditions.
2. Degradable tableware: Enzymatic action of microorganisms (bacteria, mold, algae) in the natural environment means that biochemical reactions can occur under the enzyme action of microorganisms (bacteria, mold, algae) in the natural environment, causing mildew in appearance to internal quality changes , eventually forming carbon dioxide and water tableware.
Two, different characteristics
1. Corn starch tableware: no pollution to the human body because it is refined from corn starch and other environmentally friendly materials, and does not contain harmful substances to the human body, so it can be used for a long time at ease; zero-pollution products are buried in the soil, and at a suitable temperature, After 90 days, it can be degraded to form carbon dioxide and water, and will not pollute the soil and air; the high-quality product has good dense weaving, water resistance, oil resistance, impermeability, and has good high and low temperature resistance, suitable for refrigerator freezing, cold storage, and fresh preservation Food, microwave heating, etc.
2. Degradable tableware: easy to use, degradable; light in weight.
Three, the main components are different
1. Corn starch tableware: the main components are low molecular components such as carrier resin, corn starch, coupling agent, wetting agent, and phase solvent.
2. Degradable tableware: made of plastic as the main component, with starch, photosensitizer and other substances added.
