Custom printing packaging for food is very necessary, even if the food has inner packaging (plastic container or glass container). Paper packaging is relatively capable of printing various contents and used to explain products. For example, a detailed product description can be printed on a black box, allowing customers to understand the product from various parameters, which will increase the customer’s trust in the product. The safety of food is crucial for consumers, so detailed parameter descriptions will enable customers to have a deeper understanding of food. Custom paper packaging can also make the design easily reflected on the box, allowing food to be interpreted to customers with a unique vision. The square box formed by 350gsm single powder paper has low manufacturing cost and has become the first choice for most food packaging.
