The design and application of food packaging are as follows.


From the dazzling array of food displays in supermarkets, one can find a commonality: most food companies' products are conventionally presented in a series, with similar differentiation methods used for different flavors of similar products. Taking soft drinks as an example, orange juice is invariably represented by orange, blueberry juice by blue, strawberry juice by pink, and apple juice by light green. This is true for soft drinks, and it is the same for snack foods, such as "pie" snacks.
 
Now let's make a hypothesis: if one is orange juice, one is mandarin juice, one is grapefruit juice, and one is mango juice. Can they be distinguished solely by color? I think it can't be that simple! At this point, it is necessary to use "synesthesia" to further express "taste".
 
Through the reasonable use of color and the relationships between colors, it is easy to express the "mouthfeel" of food, just as most educated students use color to express the composition exercises of sour, sweet, bitter, and spicy. On this basis, continue to use the technique of "synesthesia" to express taste as much as possible. To express taste, it is not only through the use of color but also more through the form, material, and specially designed graphics of the packaging container.
 
The biggest difference between food packaging and daily consumer goods packaging is that: while food expresses product attributes, it must fully convey its appetite and perceptual associations. If it only stays at the design expression of "what" and does not further deepen to express "how," then this product on the shelf, if it lacks advertising support, the sales can be imagined.
 
When designing food packaging, the first consideration in graphic design should focus on two levels of expression: "taste" and "mouthfeel." Only after achieving these two points can one further improve from aspects such as packaging structure, material use, and industry standards. Here, "taste" refers to the chewing sensation, such as soft, sticky, hard, crispy, smooth, etc., which all belong to the category of taste; while sweet, sour, salty, and spicy perceptual flavors belong to the range of mouthfeel. Most packaging graphic designs only pay attention to mouthfeel, often neglecting the expression of taste. As a result, they fail to fully present the characteristics of the product, which can be said to be a deficiency.

How to choose a high-quality spray filling machine

In recent years, due to the continuous development of science and technology, the aerosol filling machine industry has experienced rapid growth, especially with the widespread application of automation and intelligent technology, allowing us to enter the automation era more quickly, which has greatly benefited the filling machine industry. Due to the huge market demand for filling machines, many domestic enterprises have joined this industry, and foreign companies have also targeted the Chinese market, which has brought tremendous competitive pressure to the development of aerosol filling machine enterprises. Today, I will introduce what kind of equipment the Haochao aerosol filling machine is.

The development direction of filling machines is high intelligence.

The usage status of filling machines not only reflects the operational situation of a company but also indicates the current stagnation of the enterprise. During a period of strong cooperation, holding the main force and disadvantages has always been a key strategy for gaining market share. For many consumer-oriented enterprises, the use of filling machines is a fundamental production packaging facility. The stagnation progress of modern machinery and equipment has become a major factor in measuring the success or failure of an enterprise's stagnation, as upgrading to new equipment brings more economic benefits to the company. Although the filling machine industry does not experience the rapid stagnation and upgrading progress seen in high-tech electronics, under such a large economic situation, the use of filling machines has largely become a standard for measuring the progress and strength of an enterprise.

What are the common crushing methods of crushers, and what should be done if the crusher is clogged?

The alarm current value for the fixed plate conveyor should be appropriate, neither too low nor too high. If it is too low, the crushing chamber will frequently run out of material, and stones may hit the plate conveyor; if set too high, the lower chamber will have too much material, and there won't be enough buffer space. If there is a fault in the downstream equipment, it can also easily lead to material blockage in the crusher. Practice has proven that a setting value of 33A ensures continuous and stable discharge from the crusher while leaving enough buffer space in the lower chamber to effectively prevent material blockage.

The Importance of Soil Pollution Prevention and Control in Agricultural Land

In recent years, soil pollution has become increasingly severe, damaging the natural environment and threatening the safety of agricultural products and people's health. Incidents such as the "Changzhou toxic land case," "Xinxiang cadmium wheat," and "Jiujiang cadmium rice" have sounded the alarm for us: the prevention and control of soil pollution cannot be delayed.
