A method for improving the glossiness and ink color fastness of a printed color film is disclosed. The printed color film is a composite biaxially oriented polypropylene (BOPP) film. The method includes: (1) pre-treating the outer and inner surfaces of the composite BOPP film; (2) coating the outer and inner surfaces of the composite BOPP film with a surface-modifying coating agent and drying at a high temperature; and (3) printing the outer surface of the composite BOPP film with a water-based colored ink, and drying to obtain the printed color film. An application of the printed color film obtained by the method for tobacco packaging film to improve the glossiness and the ink color fastness of the printed color film is also disclosed.

A robotic arm includes a base, a first robotic arm, a second robotic arm, a robotic hand and a cigarette holder connected in sequence. The cigarette holder includes a cigarette insertion hole and a cigarette smoking tube. The cigarette smoking tube is connected to a smoking simulator. The robotic arm further includes at least one air exhausting hole. The air exhausting hole is located around the cigarette holder and communicated with an air exhauster through an air exhausting pipe. The robotic arm swings to control the cigarette holder to carry a cigarette from a smoking position to an ash flicking position. Airflow is formed near the air exhausting hole by means of air exhaustion, so as to simulate influences of a wind speed in an outdoor environment on the columnar ash in the cigarette smoking process of the human body.

Robotic arm for simulating cigarette smoking process

A smoking path simulation system includes a case, the robotic arm fixedly provided in the case and a cigarette holder mounted at a working end of the robotic arm, and further includes a feeding device, a cigarette tapping device and a cigarette lighting device provided in the case and located at a periphery of the robotic arm, as well as an image acquisition device mounted at the working end of the robotic arm. With the smoking path simulation system, an action path of smoking a cigarette by a consumer may be simulated, and consistency of the simulated action paths may be guaranteed, thus effectively improving precision of test of indexes of a cigarette-combustion performance, such as cigarette-combustion ash integration characteristics, or the like.

A high-transparence fiberglass paper includes vegetable parchment which is successively coated with a base layer, a second layer and a protective layer on both sides. The base layer and protective layer are prepared using water-based paints, while the second layer is prepared using UV ink through curing. The transparency and surface smoothness of the fiber is thereby greatly improved. Through treatment on the both surfaces, the paper can be processed into a light and smooth paper, with a surface smoothness of both sides more than 200 s, just like hyaline paper.
