Testing for the Harmful Influence of Light on Packaged Food and Drink Products
Atlas, a global leader in weathering testing instruments and services offers a range of solutions for accelerated weathering of packaging for food and drinks.
Transparent packaging is a commonly used for food and beverages because it is inexpensive and allows the consumer to visually see the contents of the item being marketed. From production to consumption, this packaging needs to resist harmful influences of artificial light as well as natural sunlight over long periods of time.
Product consistency is a big issue. Manufacturers are concerned with the function and aesthetic of product labels and packaging. Fading, yellowing and even the possibility of contaminants leeching through packaging material are all possible. To protect against the harmful effects of light, many companies add expensive light stabilizers which typically means passing along that added expense to the consumer.
The most critical failure mode for packaging is caused by UV-radiation which can initiate a decrease of CO2 concentration, resulting in changes in flavour.
Atlas now offers solutions for manufacturers to reduce their use of expensive stabilizers and test product before it leaves the plant. For the most realistic lightfastness testing, Atlas recommends using one of several xenon arc weathering instruments. Atlas xenon and state-of the art filter technology can be used to simulate various lighting conditions for both indoor and outdoor applications. A wide range of temperatures can be selected giving technicians and researchers the tools they need to replicate relevant test scenarios.
From film bags to bottles and everything in between, it’s never been easier to realistically test your products for changes in appearance, taste or purity after exposure indoors or out.
