A clear view on food packaging
Clear and highly transparent packaging is an important quality parameter. Products in cold storage are much more appealing to the customer when they present a visually attractive appearance without water condensation on the inside of the packaging.
Palsgaard offers a range of antifog agents for packaging applications, all based entirely on vegetable oils. No more worries about food contact!
Why use antifogging agents?
Fogging appears when fresh packaged product is placed in refrigerated storage. To overcome this problem antifogs are used to control water condenzation in the packaging.
An antifog will lower the surface tension on the film surface and make sure water droplets are not formed which not only guarantees high transparency, but also assures that water is not collecting inside the packaging which otherwise could deteriorate the product and shorten shelf life.
Antifog agents are also used in agricultural and greenhouse film, where they prevent water droplet formation and ensure better light transmission resulting in higher crop yield.
How they work
Antifogs will migrate to the polymer surface and lower the surface tension with the result that water no longer condensate as small discrete droplets but as a continuous water film. This will provide full transparency of the packaging and also help to prevent collection of moisture in the packaging that could lead to a loss of product quality and shortened shelf life.
