Description

Technical Field

[0001] The invention relates to the technical field of paint packaging, in particular to a recyclable paint packaging box. Background Art

[0002] The so-called paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the object to be coated. It is usually a viscous liquid made of resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and prepared with organic solvents or water. At present, the paints used in the market are all packaged in plastic barrels and iron barrels, but some components in the plastic barrels may react with the chemicals in the paint, causing the barrels to break or release harmful substances, affecting the quality and safety of the paint. In addition, plastic barrels are relatively not strong enough and are not suitable for long-distance transportation and storage. Iron barrels are prone to rust when in contact with water-based paints (such as latex paints), affecting the quality of the paint. The iron barrels themselves are also prone to rust and aging. Therefore, the use of plastic barrels and iron barrels to package paints usually requires frequent replacement, resulting in a waste of natural resources and is not conducive to energy conservation and emission reduction.
