[China Packaging Network News] At present, China's sauce viscous items are divided into two categories: 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.
Sugar packaging is still dominated by plastic bags, but the trend is clearly toward paper bag packaging. Paper bag packaging more in line with environmental requirements, is a trend of packaging. In addition, the function of the paper is no longer comparable, it can have high strength and good moisture resistance, printing, bag making technology has also been improved. At present, there seems to be no effort in the packaging design of sugar and salt, and the appearance is tedious. If some new packaging designs appear, consumers will easily accept it.
PET wide-mouth bottles are expected to become the main mode of packaging for sauces. There are two types of packaging for sticky viscous items: bags and bottles. Low-grade sauces are packaged mainly in plastic bags. Some medium-to-high-end seasoning sauces such as chili sauce, tomato sauce, and various kinds of jams are all packed in glass bottles and are equipped with plastic caps to facilitate multiple opening and closing. Some sauces also have aluminum plastic sealing film to extend the shelf life. Shaped bottles mainly appear in some high-end sauce packaging, such as salad dressings. Small-size packaging sauces, such as ketchup used in fast-food restaurants, are basically aluminum-plastic composite packaging. 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 not only exquisitely printed, but also can extend the shelf life, but still do not solve the problem of secondary closure. In addition, there are more and more plastic bottles. Wide-mouth PET bottles have begun to be used in jams, sesame and other packaging, and salad dressings are mostly based on PET bottles. At present, there are few wide-mouth PET bottle production lines introduced in China, mainly because the demand is small, but with the transition from high-end products to sauce products, PET wide-mouth bottles are expected to become the most important packaging form of such condiments.
There are a large number of large-sized condiments such as pepper and aniseed material, and peppers and garlic can also be included in them. Most of these seasonings are still in the extensive operating stage. Most of them are in bulk, and there are only single-layer plastic bags that are packaged and are relatively simple. In addition to this type of condiment itself is not "fine", the price is not high, there is no brand may be an important factor in the simple packaging. From a development point of view, plastic bags will be the ideal choice for larger sizes, while wide-mouth bottles are suitable for smaller-sized family sizes.
Condiments are accessories for cooking, unlike the one-time consumption of rice. Therefore, the condiment has some special requirements on the packaging, including repeated sealing, light protection, stability and so on. The packaging of low-grade sauces is based on plastic bags. From the material point of view, the plastic film is very suitable for sauce packaging, the problem is that the plastic bag is lack of secondary sealing function, and the sauce is usually a very strong smell of food, whether it is in the refrigerator or the kitchen cabinet , Will send thick smell from the opened package. It is irresponsible for consumers to request secondary packaging after purchase. Therefore, although the ordinary plastic bag packaging sauce foods can meet the requirements of the cost, but comprehensive consideration, there is still need for reform.
