Color printing packaging is almost everywhere in our life now, and its applicable products are also diverse. Whenever we go to buy food, a beautiful outer packaging can often attract our attention. So I will pay more attention to food safety in food, and the safety of its ink is also very important for food, So what kind of ink is safe to use.

Food label printing clearly shows the production period, shelf life, materials and other commodity information for people to purchase. Its unique bar code printing also provides convenience for cashier, which is a very necessary color printing package. However, as a chemical product, the ink used in printing more or less has some ingredients that are not edible, If the selection of ink and the ink treatment process in the printing of food packaging are not up to the standard, there may be direct contact with food, making the safety and health of some food can not be guaranteed, then what kind of ink is safe to use?

In a professional food color printing and packaging factory, we learned that the current standard food color printing and packaging are generally suitable for low migration ink. This ink is characterized by rapid hardening and strong adhesion. In the process, it can be printed quickly on the packaging materials without migration and adhesion, effectively avoiding contact with food.

In addition, the new non migration UV printing achieves the low migration standard through the corresponding process control. The more cross-linking components used in the ink formula, the higher the ink hardening degree, and the less the migration potential of the unreacted components in the ink. The new non migration ink series can also ensure the safety and reliability of the printing process to a certain extent.

Professional food color printing and packaging factories will consider safety issues when selecting and using ink, which can be assured that the use of low migration ink is to ensure that the color of the outer packaging can also not pollute the food, which is a very reasonable and safe ink product.

At present, color printing packaging is widely used, and the packaging of basic products can not be separated from it. It not only plays the role of publicity, but also can protect the product. Its colorful appearance is the main reason for people to choose it, so the appearance is very important. The gloss of the packaging also determines the quality of the packaging. What factors affect the gloss.

1. Ink will affect the hardness of printing and packaging gloss, mainly the smoothness of ink film, which is determined by the nature and quantity of binders.

2. The printing pressure is the key to the good transfer of the impression. If the pressure is too high, the impression will gradually expand and the gloss will become worse.

3. The gloss of color printing packaging has a great relationship with the roughness of the object surface. If the roughness is high, the more light will be reflected. By using the principle of light scattering, the glossiness will decline. If the roughness is reduced and the surface is smooth and flat, the glossiness will also be high.

The above contents are basic influencing factors, so we should pay attention to the control of the production process in the production process of color printing packaging. Good production technology and quality supervision can make our packaging products more excellent.
