The coefficient of friction or COF is the property of packaging films that explains how much force is required to slide a packaged sample from one location to another. To conduct this test, the coefficient of friction tester is a highly effective machine which is often used in packaging industries to measure the frictional properties of the materials.

Relation between COF Packaging films Quality

The COF is one of the major characteristics of the packaging films, plastic sheets and other related materials. By evaluating this factor we can find out the amount of friction that material has. By this, we can compute the time period for which the material can be kept in a state of motion without affecting the quality of the product that is packed inside. The irrelevant evaluation of COF of packaging films can lead to many quality defects in the packaging material and can also affect the safety of the goods inside. It can also lead to several problems that the manufacturers have to bear at the time of storage, warehousing, transportation, etc.

Thus, assessment of COF property helps the manufacturers to judge the amount of force or pressure required to slide the material from one place to another easily. It also helps them to measure the stacking strength of the material without slipping over each other.

The Testing Apparatus

Friction could result from uneven film thickness which leads to uneven film strength. The coefficient of friction tester tells about the degree of abuse a plastic film will sustain without damaging the contents.

Labtiger’s Coefficient of friction tester is an efficient instrument used for indicating the starting and sliding friction of plastic films and sheets. This test helps in reducing the slippage of materials and leading to sliding over itself or other substance. It complies with testing standards of ASTM D618, ASTM D 883, BS 2782, and ASTM D 1894.

Important features of the machine we deliver:

  • Microprocessor based display for accurate dynamic and kinetic friction evaluation.
  • Highly accurate test results under uniform sliding friction.
  • Slider block for performing tests – sample to sample, or sample to glass or metal
  • No slippage in case specimen is tightened uniformly using fly screws without any loops.
  • Bright LED display with feather touch controls
  • Easy handling & operation
