Resumo
Lately the environmental conscience has been strongly rising around the world, even though
some production processes, among them the deep drawing process, cannot attend the necessitiy
because of, among other reasons, the technical difficulties to produce a material that is less
aggressive to the environment and due to the cost raise that the use of that product would be
added to the process. Therefore, the objective of this project is to produce a protective film with
physical and mechanical properties that is capable of substitute the actual polyvinyl chloride
or, in less amount, polyethylene films produced with organic solvent-based adhesive, which are
largely used nowadays. One environmentally less aggressive alternative would be the
substitution of the current products by a film produced from polyolefin using water based
adhesive and that is the general objective of this dissertation. In order to achieve the objectives,
the samples of graphene oxide were produced and mixed with a matrix of LDPE using an
extrusion with twin screw. Afterwards a film was produced using a monolayer blow film
extrusion line. All the materials were analyzed after each stage of production and it was noted
that the mixture was as good as expected although the produced film did not show the expected
characteristics to achieve the objectives of this dissertation.
