How to identify cornstarch tablewares？
Corn starch tableware is a biodegradable product. It is made of corn starch as the main raw material and 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 oil.
1. It can be divided into three aspects
A. Visual observation means that starch products are matt products with some light yellow or milky white, while non-starch products are dark or bluish white
B. Odor identification means that the starch products have a light corn paste smell or plant flavor, and other products have plastic smell after the heat generated by the friction of the same products
C. Combustion discrimination means that the two types of products burn red flame for starch and blue flame for other types, and the ash after burning is crushed by hand, and the black powder is starch products, while the powder with lighter color is other types of products
2. The main ingredients are carrier resin, corn starch, coupling agent, sizing agent, phase solvent, etc
3. Floating objects may be caused by two conditions
A. The lubricant is added too much and is not completely volatilized during processing, which makes the residue pay on the product surface
B. Inorganic substances such as talc and heavy calcium are added too much to form dissolution
Advantages of disposable degradable tableware:
It is harmless to human body because it is refined from corn starch and other environmental protection materials, and does not contain substances harmful to human body, so it can be safely used for a long time.
The zero-pollution product can be degraded to form carbon dioxide and water after 90 days in the soil at a suitable temperature, without causing pollution to the soil and air.
Resource-saving corn starch is a renewable resource, which is inexhaustible. Paper tableware and plastic tableware require a large amount of wood and petrochemical products. Using corn starch as raw material can save a lot of oil and forest resources.
High quality products have good compactness, water resistance, oil resistance, and penetration resistance, as well as good resistance to high temperature and low temperature. They are suitable for refrigerator freezing, cold storage, fresh food, microwave heating, etc.
