Oxygen Absorbing Adhesive Patches


FreshMax® is the world's first oxygen absorbing patch. FreshMax® was specifically designed for adhesion within packaging of high value foods where oxygen absorption requirements are at levels below 50cc. FreshMax® absorbers protect foods against color change, rancidity, loss of nutritional value, and mold growth. They are adhesive backed and offer a flat, flexible format, with an ultra-thin, low profile design, making them seemingly invisible. FreshMax® has proven so successful in protecting high value foods, it has been recognized with national and international awards in the packaging industry.

FreshMax® has been found to be effective in absorbing low levels of oxygen when used with many kinds of packaging materials including EVOH and PVDC. Some important considerations to keep in mind regarding certain types of packaging include:

  • Adequate barrier should be used - Materials must be checked for their oxygen permeability.
  • Hermetic seals are essential - Non-hermetic seals reduce shelf-life by using up oxygen absorber capacity prematurely.
  • Package geometry - The package must be designed so as to allow free circulation of air around the product.

It is recommended that application tests with actual materials and equipment be conducted before using and specifying FreshMax®. This includes determining the water activity of the product as nearly as possible, at what temperature the product will be packaged, and specifications of the packaging film.

FreshMax® can be easily applied or inserted using high-speed dispensing or insertion machines. The absorbers are available in numerous sizes to fit your existing or new packaging requirements, and can be customized with your company graphics, promotional copy, instructions, etc.
