Abstract
The invention relates to a polypropylene (PP) film (tobacco film) stiffness increasing agent. The PP film stiffness increasing agent is characterized by being formed by mixing and extruding polypropylene, C5 petroleum resin and antioxidant serving as raw materials, wherein the PP film stiffness increasing agent comprises the following raw materials in percentage by mass: 50 percent of polypropylene, 49.5 percent of C5 petroleum resin and 0.5 percent of antioxidant. The stiffness increasing agent can improve the stiffness of a film.
Description
Technical field
The present invention relates to a kind of PP film (cigarette film) intensity strengthening agent.
Background technology
The deflection of existing PP film (cigarette film) is bad, glossiness is not enough, difficult packing (shrinking not tight).
