Method for testing and evaluating attrition degree of packing film for cigarette

Abstract

A test and evaluation method for the wear degree of tobacco packaging film is characterized in that the worn area of the film is quantitatively measured through chromating, imaging, image analysis processes upon the worn film to determine the the wear degree of the film. Compared with the current technology, the invention has the advantages as follows: 1, the chromating process proposed by the invention enables the scratches on the surface of the film to be intuitively seen, which is applicable for the quantitive evaluation of the wear degree; 2 the worn area is measurement which is realized by the means of image processing and image analysis software can realize quantitive analysis of wear degree, which is more precise and approximate to the quantitive analysis in comparison with the method for evaluating wear degree by the means of haze difference; 3 the method of the invention has simple operation and easy popularization.

Description

technical field [0001] The invention belongs to the evaluation technology of the abrasion degree of plastic film for packaging, and in particular relates to a method for testing and evaluating the abrasion degree of packaging film for cigarettes. Background technique [0002] Cigarette packaging film is the outermost packaging material for wrapping a piece or a pack of cigarettes. On cigarette packaging, the cigarette film is required to have high gloss, low haze and other specific functions, which can better maintain the original good quality of cigarettes. Quality, maximize the display of the exquisite patterns of cigarette trademarks to consumers, and convey a high-quality and beautiful visual effect to consumers. However, during the packaging and circulation process, the original good optical properties (gloss and light transmittance) of cigarette packaging films are reduced due to wear and tear on conveyor belts, boxes and other objects. Therefore, how to maintain the ...

AI Technical Summary

Problems solved by technology

Research on the wear resistance of cigarette packaging films by domestic enterprises is in the exploratory stage, and the research progress is slow, mainly because of the lack of a scientific research method. Equipment, a method for measuring the wear resistance of BOPP film for cigarettes. This method examines the wear performance of the film by studying the change of film haze before and after wear with an ink abrasion meter, but this method has certain limitations. This method First, manually select the wear area, and then conduct a haze test on the area. The test results are greatly affected by human factors. In addition, for the film with serious wear, the data of the haze method test is not accurate

There are also some film manufacturers to directly measure the wear degree of the film by manually observing the worn BOPP film. This method is greatly affected by human factors.
