  ABSTRACT: Different types of plastic films are used in agriculture to cover silos storing silage. The most important characteristics of a tarpaulin for sealing the silage are: thickness, color and polymer used in the manufacture of the film. The objective of this study is to measure and compare the thickness, the use of two instruments (digital micrometer and digital thickness gauge) in plastic films (polyethylene, polyester and polyester/vinyl). This methodological analysis for the use of micrometer digital, for future use (Agronomy and Veterinary sciences). In comparison the thickness of the three factors. 5% by Tukey test revealed that for polyethylene, there was no significant difference between factors. This methodology is satisfactory for the types of films and range of thicknesses studied.
