Over the past several decades, food packaging has experienced a quantum leap in higher quality and lower price, thanks to plastic injection molding. However, one problem has plagued the production of clear plastic food packaging: clouding. Cloudy, semi-opaque plastic food packaging has been shown to have a direct impact on consumer sales.
A myriad of solutions have been proposed to solve this issue, with differing degrees of success. Recently, a multi-national plastics company announced an energy-saving and extremely potent clarifying agent for use with their leading plastics. Many industry analysts predict the resulting clearer plastics will lead to a new generation of highly-transparent, super-glossy polypropylene random copolymers (PP) for low temperature processing of thin-wall rigid food packaging and storage. These new, clearer, plastics will give the food packaging and kitchen storage solutions industries a new standard of sparkling, glass-like clarity.
This clarifying agent was selected for its top industry performance in terms of translucence and stiffness.
Advantages of this new technology include:
* Superior visual clarity, comparable to glass
* Superior organoleptic properties. Using a new phthalate-free catalyst, the new plastics are made without peroxides, which results in the excellent organoleptic properties required by the food industry. Both grades are low in odor and carbon emissions, to boot.
* High fluidity: Elaborate designs and thin walls are possible during injection molding, due to the high-fluidity of the new additive-enhanced plastics. These new grades are optimal for differing-sizes of stiff containers for food packaging, and home wares where high clarity and and superior stiffness is necessary.
*Energy-savings and manufacturing time reduction: the new clarifying chemicals allow the melting temperature of these advanced plastics to be lowered to 170-180C during the injection molding process without any deleterious effects on the completed product. This allows injection molding companies to reduce the conventional melting temperature from 220/230C for considerably lower energy use by the extruder. This new reduced temperature reduces cooling time by at least 10% which results in more products manufactured per hour.
