Basell has introduced three new, innovative polypropylene (PP) resins marketed under the trade names Adstif HA740J, Higran RS1684 and Moplen EP310K.
The new resins are ideal for use in food packaging applications.
A desire in the packaging industry to improve productivity and reduce weight and cost are driving the development of innovative PP resins.
Improved barrier properties and aesthetics with low odour and taste, as well as the right balance of rigidity and impact resistance, are continually being demanded.
Adstif HA740J
Basell’s Adstif HA740J can address the needs of customer preformed multi-layer barrier food packaging.
The new resin is a nucleated, high-crystalline PP material for use in customer sheet extrusion and thermoforming applications, offering improved processing, high transparency and stiffness without loss of impact resistance.
Adstif HA740J has the potential for thermoformers to incorporate regrind into clear PP applications without compromising transparency.
Basell tests have shown, sheet containing EVOH and a tie layer exhibited no visible signs of degradation or yellowness, even after recycling numerous times.
Adstif HA740J resin exhibits higher stiffness, providing good dimensional stability in thinner gauges even after sterilisation, hot-filling or microwave reheating.
The new product will enable Basell to address new markets for PP multi-layer barrier food packaging.
Higran RS1684
Higran RS1684 is a High Melt Strength (HMS) PP grade that can deliver benefits in medium-to-shallow draw customer applications, such as foamed food trays used in the packaging of fresh fruits, vegetables and meat.
Food can be packed ‘in-line’, which can minimise the risk of tray contamination during transfer from line to line.
Higran also offers many advantages in form-fill-seal lines.
It surpasses polystyrene performance in foamed packaging, as it provides high dimensional stability during hot filling and microwave reheat-ability, along with excellent aesthetics.”
Basell’s new Higran RS1684 grade can be used by customers who require high performance in blown film extrusion.
Tests show that the new resin can enhance bubble stability, increasing production line output.
Moplen EP310K
Moplen EP310K is a medium flow heterophasic copolymer that is used in cast film applications such as retortable pouches, furniture, lamination film and low blush stationery films.
The resin contains no slip or anti-blocking agents and can be used in customer food contact applications.
Tests have shown that Moplen EP310K can deliver impact resistance, stiffness, processability, transparency and low gel content.
Good film stiffness with deep-freeze impact resistance, together with high heat resistance, results in packaging that can withstand a broad temperature range, allowing refrigerator to microwave use.
The exceptionally good sealing properties can expand food’s shelf life.
Moplen EP310K has improved scratch resistance and reduced shrinkage combined with easy processing and low stress whitening.
