Product Description
Laser+
®
(B90B) polyethylene terephthalate (PET) resin is a copolymer formulated for conversion to
PET bottles by conventional single or two-stage processing technology.
Typical Properties
Bi-orientation of Laser+ ® (B90B) by injection/stretch blow molding provides optimal barrier and
mechanical properties, including superior stress crack resistance. It performs exceptionally well in the
manufacture of CSD bottles made from thick-wall preforms, where heatup rate and temperature profile
through the wall are important. DAK has reengineered Laser+
® (B90B), improving acetaldehyde (AA)
performance without sacrificing intrinsic viscosity (IV), to meet increasing demand for CSD applications.
Laser+
®
(B90B) offers superior heat absorption and processing control, even at higher blowing speeds.
A slower crystallization rate enables high injection molding output.
Certification
Laser+ ® (B90B) is ideally suited for food packaging applications and is considered in compliance with
the Food and Drug Administration (FDA) Food Contact Notification (FCN) 000635, covering PET
polymers.
