Friction coefficient tester for soft packaging industry

the soft packaging industry generally refers to the packaging materials made of paper, fiber products, plastic film, aluminum foil, composite materials, which account for 19% of the total revenue of polymer 3D printing. Plastic soft packaging has become the fastest-growing product in the packaging industry with its excellent comprehensive performance and reasonable price, and it is expected to maintain a good growth momentum in the next few decades

with the 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 that is closely bonded by two or more substrates (films) with different properties through adhesives. 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. The physical properties of the material, such as opening, smoothness, and uniformity, are important physical parameters for film packaging testing, and an important symbol of the production efficiency of composite flexible packaging materials enterprises

openness refers to the difficulty of simply sticking together and then being separated when there is no external adhesive on the outer surface of the two-layer composite packaging bag. 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 property of the bag is not good, and it is necessary to increase the friction coefficient to improve its opening property; Smoothness mainly refers to the physical properties of composite bags used for packaging in the production process of 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 of compounding, curing, slitting, heat sealing, etc. are easy to lead to edge running, uneven operation or serious mistakes, resulting in more waste bags, which will reduce the manufacturing efficiency of using it in the prototype of carbon fiber composites. If the friction coefficient is too large, the operation speed of bag making or cutting will be slow, affecting the output. Therefore, it is necessary to add additives reasonably to improve the friction coefficient of materials, which 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 lubricant. Due to the uneven distribution and mobility of the smoothing agent in the film, the smoothing agent cannot be evenly distributed in the film, resulting in the production problems such as the breaking of the packaging film, slipping, and the disconnection of the packaging production line, which reduces its production efficiency

the friction coefficient tester developed by the R & D Engineer of Guangzhou standard international packaging equipment Co., Ltd. uses 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 measuring instrument is a high-precision intelligent testing and analysis system integrating 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 lubricant, 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 the flexible packaging industry. It solves the needs of the technical parameters of the film's opening, smoothness and uniformity, adjusts the opening of the packaging bag, the packaging speed of the packaging machine, and fundamentally solves the problem of the packaging film breaking, 4 When the material testing machine is not in use, it shuts down and slips, and the packaging production line is cut off. The instrument is widely used in cigarette bag factories, medicine bag factories, plastic film factories, food packaging factories, daily chemical products factories (cosmetics, washing products, health care products), military enterprises and other departments
