FreshPax Packets and Strips

FreshPax™ is an oxygen absorber pioneered by Multisorb Technologies to protect packaged foods, pharmaceuticals and other products against spoilage, mould growth, colour change, rancidity, loss of nutritive values, insect damage and loss of quality. Produced in packet form using food grade ingredients, FreshPax irreversibly absorbs oxygen inside sealed packaging to less than 0.01% and maintains this level.

FreshPax packets have several distinct advantages for your product packaging:

Extends shelf life
Prevents growth of aerobic pathogens and spoilage organisms, including moulds
Eliminates the need for additives such as BHA, BHT, sulphur dioxide, sorbates, benzoates, etc.
Use with or without gas flushing/vacuum packaging to absorb virtually all oxygen and absorb any oxygen that may permeate the package
Available in spool or fan-folded for automatic dispensing
Increases stability in oxygen sensitive compounds

Typical applications include:

Breads, cookies, cakes, pastries
Nuts and snacks
Candies and confectioneries
Coffee and tea
Whole fat dry foods
Processed, smoked and cured meats
Cheeses and dairy products
Flour and grain items
Fresh and pre-cooked pasta and noodles
Birdseed and pet food
Artwork preservation
Pharmaceuticals and vitamins
Medical diagnostic kits and devices

Examples of FreshPax Benefits:

Significantly improves keeping qualities of polyunsaturated fats and oils
Helps retain fresh-roasted flavour of coffee and nuts
Prevents oxidation of spice oleoresins present in spices themselves and in seasoned foods
Prevents oxidation of vitamins A, C and E
Inhibits mould in natural cheeses and other fermented dairy products
Delays non-enzymatic browning of fruits and some vegetables
Inhibits oxidation and condensation of red pigment of most berries and sauces

FreshPax Oxygen Absorbers vs. Ordinary Technologies

Packaging Method	Results	Benefits
FreshPax	Reduces and maintains oxygen content in packaging to below 0.01% and maintains this level despite oxygen ingress	Eliminates spoilage, organisms and oxidative chemical reactions in packaging
Vacuum & Back Flush	Achieves .5 - 2% Residual oxygen	Controls aerobic microbial growth temporarily
Gas Flushing	Approximately 0.5% to 5% oxygen	Provides some control of aerobic microbial growth

Package requirements for successful use of FreshPax

FreshPax has been found to be effective 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 - Plastic film must be checked for its 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 FreshPax. 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.

A questionnaire is available upon request to help determine your requirements.
