Condiments are auxiliary materials in catering and cooking, and their consumption volume cannot be as large as rice and flour at one time. Therefore, there are some special requirements for condiment packaging, including repeated sealing, light avoidance, stability, etc.
1. Soy Sauce and Vinegar Packaging
Soy sauce and vinegar can be considered representatives of liquid condiments, and there are many other types of liquid condiments, such as cooking wine and seasoning oils. During the planned economy era, glass bottles once dominated the packaging of soy sauce and vinegar. It can be said that to this day, liquid condiments are still one of the last strongholds of glass containers. Glass bottles do have their advantages: they are transparent, have good barrier properties, are inexpensive, and are convenient for reuse.
