Polypropylene for deep freeze resistant transparent packaging

17-Feb-05

A clarified polypropylene (PP) has been introduced to satisfy growing demand for transparent packaging that is deep freeze resistant, particularlly to serve producers of deep freeze products, such as ice cream. Development of the new clarified Borpact PP was triggered by increasing marketing emphasis on the display value of frozen desserts, combined with a lack of material choice available, and increasing need to display attributes of premium brands and products in a way that appeals to the consumer. Borpact clarified PP overcomes the technical challenge of combining transparency and low temperature impact in the thin wall, injection mouldable PP, and delivers additional productivity benefits, offering easy multi-cavity mould filling at wall thicknesses as low as 0.6mm. Some of the best demoulding and destacking properties are seen due to post-moulding, good form stability and an optimised additive package. In addition to transparent ice cream packaging, the new PP can find appliaction in food and houseware such as freezer boxes, bread bins and storage boxes. It is also suitable for a wider range of industrial packaging such as pails for coloured, water-based paints, for which transparency is a key requirement.
