aplicaÇço de polietileno linear de baixa densidade (pelbd) modificado em filmes termocontrÁteis e filmes termocontrÁteis

The use of linear low density polyethylene LLDPE modified by the thermomechanical incorporation of a free radical generator in shrink films is described, the modified stock being used isolated or in amounts of at least 50% w/w with low density polyethylene LDPE. The features of the so-obtained therm...

More Information
Summary:The use of linear low density polyethylene LLDPE modified by the thermomechanical incorporation of a free radical generator in shrink films is described, the modified stock being used isolated or in amounts of at least 50% w/w with low density polyethylene LDPE. The features of the so-obtained thermoshrinking films include better sealability, puncture resitance, tensile stress and elongation at break.
