With the increasingly stringent environmental management in my country and the pursuit of visual impact and green environmental protection by end consumers of various brands, many brands have added paper elements to their packaging design and adopted a composite packaging structure with paper trays.
The paper tray composite packaging design is novel and unique, which brings extraordinary achievements to the brand owners. However, in the production process, different color printing companies have different situations, and the composite processes used include dry composite, extrusion composite, and solvent-free composite. This also caused some problems, such as unstable process, many waste products, high odor, high solvent residue, heat sealing foaming and so on. To improve the quality of paper tray composite packaging, it is necessary to have a deep understanding of this type of packaging, and start with technology to get twice the result with half the effort.
