The packaging and printing industry, as an important supporting industry of the national economy, occupies a pivotal position in the economic system. It is not only the continuation of the production process of goods in the circulation process, but also an indispensable key link for goods to enter the market and reach consumers. From food and beverage packaging in daily life, to exquisite casings of electronic products and cosmetics, to special packaging in industries such as medicine, tobacco, and alcohol, packaging printing is ubiquitous and has penetrated into various fields.

In the food industry, packaging printing is crucial. Taking chocolate packaging as an example, exquisite patterns, bright colors, and creative designs not only instantly attract consumers' attention and stimulate their desire to purchase, but also provide convenience and ensure food safety by clearly labeling information such as ingredients, shelf life, and consumption methods. During transportation and storage, the use of environmentally friendly, moisture-proof, and fresh-keeping functional materials in packaging printing effectively extends the shelf life of food and ensures its quality is not affected.

The daily chemical product industry also heavily relies on packaging printing. Just like the packaging of perfume, the unique bottle design coupled with exquisite printing technology, such as gold stamping, UV printing, etc., makes the product fully display high-end luxury, improves the brand image and product added value, and satisfies consumers' pursuit of beauty and yearning for quality life.

In the field of electronic products, the role of packaging printing should not be underestimated. Taking the mobile phone packaging box as an example, the simple and fashionable design style, precise product information printing, and sturdy and durable packaging materials not only protect the product from damage during transportation, but also convey the brand concept and product advantages to consumers through the brand logo and product feature display on the packaging, enhancing the brand's recognition and market competitiveness.
