Application of friction coefficient tester in flexible packaging inspection

flexible packaging industry generally refers to the packaging materials made of paper, fiber products, plastic film, aluminum foil, composite materials and other materials. Plastic flexible packaging has become the fastest-growing product in the packaging industry with its excellent comprehensive performance and reasonable price. It is expected to maintain a good growth momentum in the next few decades. With economic globalization, technological progress with technological revolution and technological innovation as the main content has become the primary factor in the economic development of all countries. In order to improve market competitiveness, plastic flexible packaging is developing towards thin-walled and high-performance, and the development of multilayer composite film will become the mainstream. Composite flexible packaging material is a composite material composed of two or more substrates (films) with different properties, which are closely bonded by adhesive according to the subsequent production progress of the mineral project. Many important parameters of its physical properties need to be tested, such as friction coefficient, tensile force, heat sealing strength, solvent residue, gloss haze, oxygen and water vapor transmittance, etc. The friction coefficient is an important physical parameter in the process of bag making. Its physical properties such as opening, smoothness and uniformity are important physical parameters for film packaging inspection and an important symbol of the production efficiency of composite flexible packaging materials enterprises. Opening refers to the difficulty of simply sticking together and then being separated on the outer surface of two-layer composite packaging bag without external adhesive. If the friction coefficient of the outer surface material is too small, it is difficult to separate this operation. Therefore, it is said that the opening of the bag is not good, and the friction coefficient needs to be increased to improve its opening performance; Smoothness mainly refers to the physical properties of composite bags for packaging in several continuous processes, such as compounding, curing, slitting and heat sealing

if the friction coefficient of the material is too small at this time, the operations such as compounding, curing, slitting and heat sealing are easy to lead to edge running, uneven operation or serious mistakes, resulting in more waste bags, which will reduce the production efficiency. If the friction coefficient is too large, the operation speed of bag making or cutting will be slow and affect the output. Therefore, it is necessary to reasonably add additives to improve the friction coefficient of the material, This can provide technical parameter guidance for industrial production; The uniformity of the film refers to the uniformity of the whole surface of the material after adding the smoothing agent. Due to the uneven distribution and mobility of the smoothing agent in the thin 180 d = 5A film, the smoothing agent can not be evenly distributed in the film, resulting in the production problems such as the breakage of the packaging film, slipping and the disconnection of the packaging production line, which reduces its production efficiency

the friction coefficient tester developed by all R & D engineers of Guangzhou standard international packaging equipment Co., Ltd. adopts the surface to surface contact mode of the film, rather than measuring the static and dynamic friction coefficient of two materials in the state of point contact or line contact. The friction coefficient tester is a high-precision intelligent test and analysis system integrating multiple functions such as measurement, calibration, analysis, statistics, report generation and printing, The instrument is mainly used to measure the static friction coefficient and dynamic friction coefficient of plastic film and sheet sliding. It can meet the detection of the opening and smoothness of the film, and the real-time "display" function of the friction coefficient tester can meet the detection of the uniformity of the distribution of the smoothing agent, give the description of the essential characteristics of the film, and provide strong technical support for the formulation of parameters for process improvement. To sum up, the friction coefficient tester plays an important role in the detection of flexible packaging industry. It solves the requirements of technical parameters in terms of film opening, smoothness and uniformity, adjusts the opening of packaging bag and the packaging speed of packaging machine, and falls into "low"; "Big and empty"; It has fundamentally solved the production problems such as broken packaging film, slipping and disconnection of packaging production line. The instrument has been widely used in cigarette packaging factory, medicine packaging factory, plastic film factory, food packaging factory, daily chemical product factory (cosmetics, washing products, health care products), military enterprises and other departments
