| Friction and shrinkage factors are considered among the promising challenges in the as quality control packaging system. The research aims to evaluate the thermal range of materials used in machines to avoid the shrinkage problem by using polymers with a high degree of thermal stability. Using polymers with a friction rate achieves a problem-free operating range to meet the requirements of the products, in printing, cutting, welding, and packaging processes. Shrinkage of packaging films with high temperature during machine operation has back drain effect than standard machine operating temperature. The research utilized an experimental approach to investigate, evaluation of the fraction coefficient and shrinkage temperature has a great impact to decide the availability of the printing packaging film to applied on packaging machine unit without manufacture problem shooting. Difference in coefficient of friction from the standard rate equivalent to the normal rate required on machines during operation play a vital role in processing. Two tested printing films were evaluated with ST 52 and 63 ᵒC for bad and good processing, respectively. Studying the problems of shrinkage and slippage on machine cylinders due to the weakness of the temperature range and the low or high coefficient of friction is extreme importance for packaging films during operation, which costs the industry large sums of money and affect the environment. Five sample was examined with COF from 0.57 to 0.9 N as film/metal and from 0.2 to 0.4 N as film/film. Desired COF for film/metal in range (0.8-0.9 N) and film/film (0.2-0.3 N). | ||||
