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.

Summary
Polyethylene film (PE) is commonly used for various purposes, one of which is the coverage silos and silage. Polyesters, as the name implies, are polymers having the ester function. The fibers of polyesters can be molded by extrusion or lamination processes with other polymers such as vinyl polymers nature and give rise to different types of films [2] [3]. The cover canvas represents an important contribution, in the silo sealing stage, with the objective of reducing. The most important characteristics of a tarpaulin for silage sealing are: Thickness, coloring and polymer used in the making of the film [4] [5]. The function of a plastic when used for silo sealing is to create an anabolic condition and provide a good environment for fermentation. There are studies that have demonstrated the effects of the concentration of O2 inside the silo, causing losses of dry matter, nutrients, accumulation of pathogens [4] [5] [6] [7]
