ExxonMobil has developed a novel high-density polyethylene (HDPE) grade, ExxonMobil™ HD7165L, for Machine Direction Oriented (MDO) PE film applications.
Designed for recyclability, HD7165L can help converters create mono-material laminates to replace multi-material laminate structures which can be difficult to mechanically recycle.
Excellent Optical Properties and Heat Resistance
Designed for recyclability, ExxonMobil™ HD7165L can help converters create mono-material MDO laminated packaging structures which:
-
Offer excellent optical properties and outstanding mechanical properties
-
Can be used for packaging products like nuts, crackers, condiments, granola bars, and potato chips
“
The development of new HD7165L has been driven by market demand from brand owners and processors looking to develop all-PE packaging which, in turn, has created a need for print webs made of blown MDO-PE films,” said Nilesh Savargaonkar, Principal Customer and Application Development engineer, ExxonMobil.
ExxonMobil™ HD7165L can help enable converters to produce blown MDO-PE films with 60-70% HDPE for enhanced stiffness and high heat resistance. High output rates in excess of 400kg/hr are possible, while bubble stability is maintained. High MDO stretch ratios as high as 7:1, with very high stiffness (1% secant modulus as high as >200 kpsi) can be achieved. With haze less than ten percent and
gloss higher than 60%, ExxonMobil™ HD7165L offers excellent optical properties. Used as a print web of a PE-PE laminate, ExxonMobil™ HD7165L offers high heat resistance, stiffness for a lack of extensibility, and excellent printability for optimum brand promotion.
In blown MDO-PE film applications, ExxonMobil™ HD7165L offers high, uniform orientation, gauge stability, and low gels for easy processability. Compared to a market reference HDPE grade (density 0.962 g/cm³), ExxonMobil™ HD7165L (density 0.961 g/cm³) delivers better shear thinning behavior and extrudability, higher melt strength for bubble stability, excellent orientability, and gauge uniformity.
“
Brand owners and the value chain globally have ambitious goals around the development of packaging that can be recycled,” said Justin Schmader, CANUSA Market Development manager. “
Our ongoing innovation to develop new polyethylene grades that can help enable the creation of mono-material packaging structures is one step in helping them potentially achieve those goals.”
