Resumo
Studies have indicated that the addition of nanoparticles in flexible films improves performance
flexible packaging, leading to better mechanical, thermal and barrier properties. Clay is an
abundant mineral, inexpensive, easy to process, and provide considerable enhancements on
the properties of polymers. Titanium dioxide (TiO 2 ) is widely used for its efficiency in scattering
visible light, and imparting whiteness, brightness, and high opacity when incorporated into a
plastic formulation. Low density polyethylene (LDPE) is generally used as a packaging material
due to its good resistance, easy processing, low cost and high hardness. The objective of this
study was to evaluate the effects of clay and TiO 2 nanoparticles addition on the properties of
LDPE flexible films. LDPE with 1 wt % of TiO 2 addition and 1-3 wt. % of green Brazilian Clay,
from Cubati, Pb, Brazil were prepared by melt extrusion process, using a twin-screw extruder
Haake Rheomex P332 with 16 mm and L/D = 25, from Thermo Scientific. Then the LDPE/Clay
nanocomposite was transformed into thin films using an extrusion blown film, single screw
machine with 25 mm diameter and specimen test samples were obtained. The specimen
samples were characterized by mechanical tests, UV-VIS, DSC, TG and FE-SEM analysis.
