Which of the various water cups used daily are made of environmentally friendly materials?

With the increase in environmental protection awareness of the whole world, countries around the world have begun to implement environmental protection testing on various product materials, especially in Europe on July 3, 2021 formally implement the plastic restriction order.So in the water cups that people use every day, which materials are environmentally friendly?

When we understand this problem, let us first understand what is an environmentally friendly material? To put it simply, the material does not cause pollution to the environment, that is, "zero pollution, zero formaldehyde" materials.

So which ones in the water cup are zero-pollution and zero-formaldehyde? Is stainless steel an environmentally friendly material? Are various plastic materials considered environmentally friendly materials? Are ceramics and glass considered environmentally friendly materials?

Stainless steel materials are environmentally friendly materials. Although it is made of metal and is smelted from mineral soil and then processed by alloying, stainless steel can be degraded in nature. Some people say that stainless steel will not rust? The environment in which we use stainless steel water cups is a catering environment, and the food grade stainless steel used in such an environment is really difficult to oxidize and rust. However, in the natural environment, various factors will cause the oxidation of stainless steel to gradually decompose after many years, and the decomposed stainless steel will not pollute the environment.

Among the various plastic materials, only PLA is known to be used in food grade and is an environmentally friendly material. PLA is a naturally degradable starch, which will not pollute the environment after degradation.

Other materials such as PP and AS are not environmentally friendly materials. First of all, these materials are difficult to degrade, and secondly, the substances released during the degradation process will pollute the environment.

Ceramics themselves are environmentally friendly materials and can be degraded. However, ceramic appliances that have undergone various processes, especially those processed with a large amount heavy metals, are not environmentally friendly materials.

Glass is not an environmentally friendly material. Although glass is harmless to the human body and harmless to the environment after crushing, the properties of glass make it almost impossible to degrade.

The thermos cup produced by Dongguan Zhanyi Commodity Technology Co., Ltd. uses sufficient materials and exquisite workmanship. In terms of material, we insist on using food-grade 304 stainless steel inside and outside, or a combination of 304 stainless steel outside and 316 stainless steel. The heat preservation time can reach 8 hours, and the cold preservation time can reach 12 hours. We insist on using the AQL1.0 inspection standard, which is far higher than the peer standards, and all links adopt a full inspection system to ensure that each product is a high-quality product. Customers from all over the world are welcome to visit our factory for inspection, and welcome to place orders for cooperation.
