Customers can now see the quality of sliced fruit they’re buying, thanks to a clear polypropylene plastic jar Graham Packaging is making for Libby’s brand fruit from Signature Fruit Co. The multi-layer, lightweight, wide-mouth polypropylene container is believed to be the first to be able to withstand the temperatures of the retort process (200F for 45 minutes), according to Terry Keener, a product line manager with Graham Packaging.
Keener says Graham Packaging applied vacuum panel technology similar to that it has used in its polyethylene terephthalate (PET) hot-fill containers. The new jar incorporates vacuum panels that “barrel out” when heated and then pull back into shape after cooling.
The six-layer walls have an oxygen barrier and an ultraviolet absorber. The container has a net weight of 24.5 oz. and holds 23 fluid ounces.
George Plummer, national account manager for Graham Packaging, says Signature Fruit’s decision to shift from metal to plastic packaging took into account a number of benefits — plastic is easier to grip, it runs better on filling lines, and it is lighter.
