The accurate definition of color printing carton refers to the folding carton and color fine corrugated box made of plastic, cardboard and fine corrugated board of Shenyang Carton Factory. It has the characteristics of light weight, portability, wide source of raw materials, environmental protection and exquisite printing. At present, internationally, especially in developed countries, the definition of "color box" packaging is very clear. Paper box packaging, including food, alcohol, medicine, daily/cosmetics, tobacco, electronic products, etc., belongs to the category of "color box" packaging. From a global perspective, despite the strong challenges of plastic packaging, the color box industry is still growing steadily, and the Chinese market is even more vibrant, becoming the highlight of the global carton market growth.

1. Certain mechanical properties

Packaging materials should be able to effectively protect products, so they should have certain strength, toughness and elasticity to adapt to the impact of static and dynamic factors such as pressure, impact and vibration.

2. Isolation performance

According to the different requirements for product packaging, the packaging materials should have certain barriers to moisture, steam, gas, light, fragrance, odor, heat, etc.

3. Good safety performance

The packaging material itself should be less toxic to avoid polluting the product and affecting human health; The packaging materials shall be non corrosive and have the properties of insect prevention, moth prevention, rat prevention, microbial inhibition, etc. to protect the product safety.

4. Appropriate processing properties

Packaging materials shall be suitable for processing and easy to be made into various packaging containers. It shall be easy for mechanization and automation of packaging operations to adapt to large-scale industrial production. It shall be suitable for printing and convenient for printing packaging marks.

To sum up, the size design of corrugated boxes is a very important work in the structural design of corrugated boxes. A qualified carton product should have protection and good shape. Especially for cartons with sales packaging and transportation packaging functions, reasonable size will be the key to carton design. Because the size change will directly affect the various performance changes of the carton. In a word, in the structural design of corrugated boxes, it should be determined according to the manufacturing equipment used, different production processes, different types of corrugated paper and the types and properties of the goods inside. Only after mastering the contents related to the structure and size of corrugated boxes, can we create corrugated boxes that protect and beautify goods.
