Description
Technical Field
The invention relates to the technical field of packaging materials, in particular to a soft and smooth touch matte coating.
Background
In some packaging containers on the market, flexible packages with various colors can attract the eyes of consumers. And the packaging containers with the matte effect on the surfaces have the elegant feeling.
In the flexible package, the packaging bag with matte surface effect adopts plastic films with matte surface, such as delustered BOPP, matte PET films and the like. The matte or matte effect of these films is caused by incompatible polymer fine particles or inorganic particles uniformly dispersed in the surface layer. The poor compatibility of the dispersed fine particles gives rise to problems of poor transparency, rough hand and high surface hardness. In addition, factors in the manufacturing process determine that these films are often produced in full-scale.
In recent years, some ink manufacturers have developed matte gloss oil, which is generally prepared by adding silica particles as matting particles to a resin solution, but the coating has a high surface hardness and poor transparency, so that the appearance of the inner printed pattern is hazy. Moreover, the matte gloss oil is only suitable for being coated on the surface of a polyester film or a nylon film with higher surface tension, and for BOPP and PE films, the adhesion of the matte gloss oil is poor, so that the matte gloss oil is easy to scratch in the process of transportation and storage.
Chinese patent publication No. CN104553147A discloses a packaging material for molding, which comprises: an outer substrate layer formed of a heat-resistant resin, an inner sealant layer formed of a thermoplastic resin, a metal foil layer disposed between the outer substrate layer and the inner sealant layer, and a matte coating layer formed on the outer substrate layer on the side opposite to the metal foil layer, the matte coating layer being a multilayer having a lower layer formed of a resin composition containing a main agent resin containing a phenoxy resin and a polyurethane resin, a curing agent, and solid fine particles; and an upper layer formed of a resin composition containing a fluorine-containing resin. The matte coating provided by the patent is multilayer, and solid particles are matched with resin, so that the problems of poor transparency and high hardness still exist.
Therefore, how to develop a coating material with good transparency and good hand feeling is a technical problem to be solved by those skilled in the art.
