Different packaging requirements for different seasonings

seasonings are auxiliary ingredients in catering and cooking. It is impossible to consume a large amount of seasonings at one time like rice noodles. Therefore, there are some special requirements for condiment packaging, including repeated sealing, lightproof, stability and so on

1. Soy sauce and vinegar packaging

soy sauce and vinegar can be regarded as representatives of liquid condiments, and there are many kinds of such condiments, such as cooking wine and seasoning oil. In the era of planned economy, glass bottles once unified the packaging of soy sauce and vinegar. It can be said that liquid condiments are still one of the last few positions of glass containers. Glass bottle has its advantages: transparency, good barrier, low price, easy to reuse

in recent years, great changes have taken place. The pattern of glass bottles dominating the world has been broken, and plastic bags, PET bottles and PE barrels have entered the liquid condiment market one after another

pet bottles are similar to glass bottles in scale and capacity, but they are lighter and have better luster than glass bottles, and have bottle caps that can be used repeatedly; PE barrels are generally large in capacity, suitable for occasions where consumption is relatively fast, and the repeated sealing is also very good; PE bags provide better economy

although the glass bottle packaging still occupies a dominant position, it is worth mentioning that the previous sealing form by a single crown cap on the glass bottle has changed. It can be said that the non resealability of the crown cap is the fatal weakness of glass bottle packaging. Now many glass bottles have been improved in bottle caps, and plastic bottle caps have been used for convenience. For example, some manufacturers, such as the collider, hang a plastic cap on the glass bottleneck sealed by the crown cap, so that after the crown cap is opened, it can be replaced with this plastic cap for repeated use

small volume liquid condiments, such as mustard oil, chili oil and some high-end raw soy sauce, are still packaged in glass bottles, but all have adopted plastic bottle caps. There is no ideal alternative packaging in this market for the time being

2. Sugar and salt packaging

sugar and salt have been packaged in cloth bags, especially in large-scale transportation packaging. However, plastic bags are the main form of sales packaging. For a long time, it is necessary to regularly clean the filter in the filter through the pipe;, There is little change in packaging specifications

in recent years, some changes have taken place in the types of salt. Some functional salt products such as iodized salt have entered the market, and have gradually become the mainstream. The packaging of salt has increased the requirements of text instructions. Packaging also began to transform from a single plastic bag packaging, and carton packaging began to appear

the packaging of salt products abroad has tended to carton packaging, which is also the innovation trend of flavoring salt packaging in China

at present, the packaging of sugar is still mainly plastic bags, but the development trend is obviously towards paper bag packaging. It is more in line with the requirements of environmental protection, is a trend of packaging; In addition, the functionality of paper is not what it used to be. It can have high strength, good moisture resistance and printability. Bag making technology has also made great progress

at present, there seems to be no effort in the packaging design of sugar and salt in China, and the appearance is very monotonous. If there are some new packaging designs, consumers will easily accept them

3. Sauce packaging

the packaging of sauce viscous goods is divided into two categories: bags and bottles. Low grade seasoning sauce is mainly packed in plastic bags. Some medium and high-end sauces, such as chili sauce, tomato sauce and various jam, are packaged in glass bottles with plastic caps, which are convenient to open and close for many times. Some sauces are also added with aluminum-plastic sealing film to extend the shelf life

shaped bottles mainly appear on some high-end sauce packages, such as salad dressing. Seasoning sauces packaged in small capacity, such as ketchup used in fast-food restaurants, basically adopt aluminum plastic composite packaging

the latest development in this field is that some sauces have begun to use aluminum-plastic composite packaging, such as some seafood sauce, meat sauce, etc. These packaging are not only beautifully printed, but also can extend the shelf life, but the problem of secondary sealing has not been solved. Consumers still need to change their packaging if they can't eat it all at once after buying; The other is the increasing number of plastic bottles. Wide mouth PET bottles have been used in jam, sesame paste and other packaging, while PET bottles are the majority of salad dressing. At present, there are few PET bottle production lines introduced in China, mainly because of the small demand. However, with the transition of sauce food to high-end products, PET bottle is expected to become the most important packaging form of this kind of condiments

4. Pepper and seasoning packaging

there are a large number of seasoning crystals with large particles, including pepper, seasoning, and even pepper and garlic. Most of these seasonings are still in the stage of extensive operation, mostly in bulk, and only single-layer plastic bags are packaged, which is very crude. In addition to the fact that this kind of condiment itself is not "fine" and the price is not high, the lack of brand may be an important factor in the poor packaging. In terms of development, plastic bags will be an ideal choice for larger size packaging, while wide mouth bottles are suitable for smaller size family packaging
