Desenvolvimento de placas de embalagens ‘longa vida’ e estudo de seu comportamento como material térmico

Abstract

Long life packaging are made of multilayer paper, plastic and aluminum, which have the function of protecting the food from moisture, light and oxygen. This composition makes the material difficult to recycle, because their components have different characteristics, and it is difficult to separate them. For this reason every year, Brazil sends millions of cartons to landfills and dumps. With the challenge of increasing the number of recycled cartons, there are a seek to new methods or ways of reuse. This paper has as main objective develop signs of long-life packaging , analyzing their thermal behavior and the viability of its use to assist in thermal comfort environments. For this study were made two experiments, the first one in laboratory, and the second on a external environment, where were placed long life packaging boards on public house prototypes. Based on the analysis of the results it is not possible to conclude whether there is indeed viability of using carton packages for construction of thermal plates with the auxiliary function in thermal comfort environments. However the data show a positive indication that the board has thermal behavior.
