Right: MP-1000 combines Aptar’s Activ-Polymer with ProAm- pac’s flexible blown film technology
the contents from any moisture that passes through the packaging. Available in rollstock or pre-made pouches,
MP-1000 has excellent seal characteristics and runs on high-speed form-fill-sealing equipment, ensuring product integrity and compatibility with existing flexible packaging equipment. “The goal of this collaboration is to transform the way active packaging is delivered and fulfill unmet needs by providing the market with a fully integrated, flexible, multi-layer film solution,” said Badre Hammond, vice president of global com- mercial operations and general manager APAC for Aptar CSP Technologies.
HDPE for MDO ExxonMobil has developed an HDPE grade for machine direction oriented (MDO) PE film applica- tions. The grade, HD7165L, can help converters create mono-material laminates, which can be easier to mechanically recycle. Offering good optical and mechanical properties, the material can be used to make mono-material packaging for products such as nuts, crackers and potato chips. “The development of HD7165L has been driven
by market demand for 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 at ExxonMobil. The grade can help converters produce blown MDO-PE films with 60-70% HDPE, for enhanced stiffness and high heat resistance. Output rates above 400kg/hr are possible, while bubble stability is maintained. MDO stretch ratios as high as 7:1 with very high
stiffness can be achieved. Haze is less than 10% and gloss is higher than 60%. Used as a print web of a PE-PE laminate, it offers high heat resistance and stiffness – for a lack of extensibility.

BOPE grade SCG Chemicals has developed an HDPE resin, which it says can be processed into biaxially oriented PE (BOPE) using tenter frame technology. “It requires a unique balancing of processing and film properties,” said Kanyanut Narkchamnan, full PE research and development leader at SCG Chemicals in Thailand
Its S197F multi-modal technology is available with low molecular weight (for stiffness and processability), high molecular weight (for tough- ness) or very high molecular weight – which adds higher mechanical properties and stretchability. “BOPE film made of S197F provides high heat
resistance and good mechanical and optical properties – suitable for printing and coating in multi-layer structures,” she said. The films can be used to replace BOPA and
BOPET, she said – and are appropriate for moisture barrier applications.
