Ceramic jars are also prone to chipping. Higher costs are required in terms of shipping.
The characteristics of glass jars are transparent, you can see the condition of the things stored inside, the surface is smooth and easy to clean, the chemical stability is good, the contents are not polluted, the airtightness is high, the storage performance is good, the shape and decoration are rich and varied, and can be recycled and used many times , rich sources of raw materials.

Plastic storage tanks have good corrosion resistance, acid and alkali resistance, oil resistance, impact resistance, and good mechanical strength. Of course, plastic storage tanks also have their disadvantages: for example, plastic pipes are easily deformed at high temperatures, so the use temperature is limited; the surface hardness of the container is low, and it is easy to wear or scratch; Aging phenomena such as brittleness and performance degradation; poor conductivity and easy to generate static electricity accumulation, etc.
Metal packaging containers can not only block gases such as air, oxygen, water vapor, carbon dioxide, etc., but also block light, especially ultraviolet light, so it will not cause deliquescence, deterioration, corruption and fading of the inner packaging, and changes in fragrance. Because the metal container has high rigidity, is easy to operate, can withstand collision, vibration and stacking, and is convenient for transportation and storage, the sales radius of the product is greatly increased.
