Abstract:

Measurement of dynamic and static friction coefficient of flexible packaging composite film

In the packaging industry, plastic flexible packaging has gradually become one of the main materials of various product packaging according to its rich color forms, diverse use functions and changeable shape. Soft packaging materials are mainly made of paper products, fiber materials, plastic films, metal aluminum foil, new compliance materials and other materials. Among them, plastic film flexible packaging with its excellent comprehensive performance and reasonable cost control has become the rapid development of packaging materials in the flexible packaging industry.

Friction coefficient meter is an important physical property data in the process of producing flexible packaging bags, and also an important embodiment of the efficiency of composite film flexible packaging material production. Effect of friction coefficient on opening performance, smooth performance and uniformity of composite film soft packaging materials degree The physical properties have very important measurement standard and quality control influence.

     1 Opening performance refers to the degree of difficulty to peel off after simply adsorbing and bonding the outer surface of the two-layer composite film packaging bag without adhesive.

     2 Smooth performance mainly refers to the physical properties of the composite film packaging bag used in packaging in the process of compounding, curing, cutting and heat sealing. If the friction coefficient of the composite membrane material is too low, it is easy to cause problems such as edge running, uneven operation or serious mistakes in the production and operation of the parameters such as compounding, curing, cutting and heat sealing, which will reduce the productivity; If the friction coefficient is too high, it is easy to cause low operation speed of bag forming and cutting, thus affecting the production.

    3 The uniformity mainly refers to the surface uniformity of the composite material after adding the smoothing agent. Due to the uniform distribution and variability of the smoothness in the composite film, the smooth agent can not be well distributed on the composite film, which is easy to cause the composite packaging film easy to break, slip, and the production line flow of composite packaging.

In order to prevent the occurrence of the above problems, Jinan Chenchi instruments launched a special test instrument Mxd-01 friction coefficient instrument To ensure the qualified rate of production and reduce the production loss.

The friction coefficient meter is mainly used in Plastic reunite with Thin film, thin sheet Dynamic and static Friction coefficient test It can also be applied to Paper, cardboard Textiles, non-woven fabrics, woven bags rubber Aluminum foil, aluminum foil composite film, metal products Printed matter Etc Static friction coefficient and dynamic friction coefficient test

The friction coefficient instrument integrates the functions of numerical measurement, numerical calibration, data analysis, data statistics, data report and result printing. The instrument is fully automatic test; The imported high-precision force sensor is adopted, and the force accuracy reaches the domestic * high 0.001N The instrument has no mechanical control knob; All digital intelligent test system; Automatic calibration and zero adjustment of test data; The driving system adopts special design, the instrument runs smoothly and completely shields the influence factors of mechanical vibration on test results; The instrument adopts HD 320*240 Liquid crystal display, screen real-time display of dynamic and static friction coefficient; Test printing report layout is clear and reasonable; Multi group data intelligent statistical analysis function; The operation of the instrument is more intelligent and convenient.
