Description

Composite structure and smoking article comprising same Technical Field The present utility model relates to a composite structure and a smoking article incorporating the composite structure. Background With the improvement of the product experience requirements of consumers, materials with fragrance emission function are increasingly paid attention to. For example, for food, cosmetics, gifts, etc., the packaging may be performed using a scented material (e.g., a scented paper) to impart additional features and styles to the merchandise. Disclosure of utility model However, the authors found that for a perfumed material formed by applying a perfume directly onto a substrate, the decay of the perfume is rapid, resulting in a short duration of the perfume. In addition, the fragrance of such a perfuming material decays rapidly, resulting in an excessively intense initial fragrance throughout the entire perfumed period, but almost disappears after a while, and the intensity of the fragrance is not uniform. In this regard, a composite structure is provided that includes a substrate, a plastic layer, an optional first flavor layer, and an optional second flavor layer. The substrate has a first side and a second side opposite the first side. The plastic layer is located on the first side of the substrate. The plastic layer comprises a biodegradable plastic, and the plastic layer optionally contains a glue line scent. The first fragrance layer is positioned between the substrate and the plastic layer, and the first fragrance layer is provided with a first fragrance agent. The second fragrance layer is positioned on the second side of the substrate, and has a second fragrance therein. When the plastic layer does not contain the glue layer flavor and the first flavor layer is not arranged between the substrate and the plastic layer, the composite material structure is required to have the second flavor layer. By means of the characteristics, the composite material structure can reduce the fragrance attenuation speed, so that the composite material structure has long fragrance duration time. Specifically, in some embodiments, the composite structure has a plastic layer containing a glue layer scent agent, and since the glue layer scent agent is dispersed in the plastic layer, the releasing speed of the scent agent can be effectively reduced compared with the case that the scent agent with the same amount is directly coated on the substrate and directly dissipated or indirectly dissipated to the outside through the substrate, thereby prolonging the lasting time of the scent of the composite structure. Or in some embodiments, the first fragrance layer is arranged between the substrate and the plastic layer, and the fragrance of the first fragrance layer is blocked by the plastic layer when released, so that the releasing speed of the fragrance is reduced. Or in some embodiments, since the substrate has the second fragrance layer on the second side and the plastic layer on the first side of the substrate opposite the second side, this structure reduces the amount of fragrance escaping from the first side of the substrate through the substrate by the second fragrance layer, as compared to when no plastic layer is provided. For the reasons, the composite material structure can reduce the fragrance decay speed, so that the composite material structure has longer fragrance duration time. Also, because the rate of flavor decay is relatively slow, the composite structure can have a relatively stable, uniform flavor throughout the duration of the flavor. In addition, the composite structure has the effect of releasing the fragrance gradually under certain conditions. When the composite structure is applied to a product (such as a roll paper of a smoking article) which is heated, if the composite structure is provided with the plastic layer containing the adhesive layer flavor agent, the plastic layer can gradually release the adhesive layer flavor agent due to the fact that the plastic layer is softened and melted along with heating, so that the composite structure can further gradually release the flavor. If the first fragrance layer is arranged between the base material of the composite material structure and the plastic layer, the fragrance of the first fragrance layer which is blocked originally can be gradually released along with the gradual softening and melting of the plastic layer when the plastic layer is heated, so that the effect of gradually releasing the fragrance is achieved. If the second fragrance layer is provided on the second side of the substrate, the plastic layer on the first side opposite to the second side is gradually softened and melted by heating, so that the fragrance amount of the second fragrance layer escaping from the second side to the first side is gradually increased, and the composite material structure has the effect of releasing the fragrance gradually. Accordingly, a smoking article is al
