With the development of China's packaging industry, sauce packaging has also developed. However, at present, China's sauce packaging still has certain problems, and the market needs more diversified and refined products.
There are two types of packaging for sticky viscous products in China: bags and bottles. However, both low-grade bag packaging and high-grade bottle packaging require further reforms and improvements. The latest development in this area is that some sauces have begun to use aluminum-plastic composite packaging, such as some seafood sauce, meat sauce and so on. These packages are beautifully printed and can extend the shelf life, but still do not solve the problem of secondary closure. After the consumer purchases, if he can't eat it immediately, he still needs to change his own packaging; another type of plastic bottle is increasing. Wide-mouth PET bottles have begun to be used in jams, sesame and other packaging, and salad dressing bottles are mostly PET bottles.
Condiment packaging equipment needs to produce more diversified and refined products. At present, there are few wide-mouth PET bottle production lines introduced in China, on the one hand because of the small demand; on the other hand, it also constrains the application of PET wide-mouth bottles. However, with the transition of granular and sauce-based foods to high-end products, PET jars are expected to become the most important form of packaging for such condiments. The packaging of sauce condiments in China mainly uses bottles and bags. However, no matter what kind of packaging methods, there are more or less problems such as the lack of secondary seals, and they need to be improved and improved.
Glass bottles still dominate the soy sauce and vinegar packaging. Glass bottles are transparent, have good barrier properties, and are low in price, making them easy to reuse. Although plastic bags, PET bottles and PE barrels have entered the liquid condiment packaging market in recent years, glass bottles still dominate. It is worth mentioning that in the past, the single crown cap closure on glass bottles has changed. It can be said that the imperfection of the crown cap is the fatal weakness of the glass bottle packaging. Many glass bottles have now been improved in terms of caps, and plastic caps have been used to facilitate their use. Some manufacturers also have a plastic cover hanging on the glass bottle cap of the crown cap. In this way, after the crown cap is opened, the plastic cap can be replaced and used repeatedly. Small-capacity liquid seasonings such as mustard oil, chili oil and certain high-grade raw soy sauces are still packaged in glass bottles. However, all plastic caps have been used. There is no ideal alternative packaging for this market. Salt sugar products carton packaging is the trend of innovation In recent years, some changes have taken place in the type of salt, iodized salt and other functional salt products into the market, has gradually become the mainstream. The packaging of salt was added to the text description. From the packaging of a single plastic bag, there was a carton-type package. Foreign salt product packaging has tended to carton packaging, which is also the direction of innovation in salt packaging in China.
