Cardboard packaging refers to the packaging of products using paper boxes during the distribution process to protect the products, facilitate storage and transportation, and promote sales. It is a widely used packaging method. Different from wooden box packaging, woven sack packaging, cloth sack packaging, and plastic box packaging, cardboard packaging has characteristics such as easy sourcing, light weight, easy printing, easy design and molding, and low cost, making it widely used for both sales and transportation packaging of goods.
