HB 4000 PET features a patent pending co-extruded sheet
comprising active and passive layers with superior oxygen barrier
performance. Once this multi-layer material is thermoformed, an instant
barrier is created. Consistent layer thickness eliminates oxygen
permeation. Earth-friendly HB 4000 PET can be recycled with no negative
impact on the recycling stream and can safely be recycled with bottles
and retail thermoforms in communities where recycling channels exist.
