Abstract

The invention discloses a perfuming colorful packaging paper and a preparation method thereof. The packaging paper has multiple layers, wherein an inner layer is in direct contact with a packaged article; an outer layer is arranged away from the packaged article; the outer layer is arranged as an over-printing varnish layer; the inner layer is arranged as a perfuming colorful layer; a decorative printing layer and a base paper layer are arranged between the over-printing varnish layer and the perfuming colorful layer; the decorative printing layer is arranged close to the over-printing varnish layer; the base paper layer is arranged close to the perfuming colorful layer. The perfuming colorful packaging paper provided by the invention has the natural plant fragrance; the fragrance is relatively long-lasting; elegant fragrance can be brought to the consumers; the color of the back of the packaging paper is coordinating and harmonious with the fragrance; the fragrance is organically combined with the color, so that the product grade is increased.

Description

technical field [0001] The invention relates to the technical field of the packaging industry, in particular to a scented colored packaging paper and a preparation method thereof. Background technique [0002] Wrapping paper is safe and environmentally friendly, light in texture, easy to process and shape, and has good printing performance. It is the first choice for industries such as food, medicine, tobacco, and cosmetics. Beautifying products and conveying brand information is one of the important functions of packaging paper. In order to strengthen this function, new products such as aluminized wrapping paper and laser wrapping paper have been developed. These new products are bright in color, bright in appearance and strong in visual impact, which can well improve the product packaging grade. However, whether it is aluminized packaging paper or laser packaging paper, it only gives consumers a strong visual impact, but cannot fully touch other sensory systems of the hu...
