| OUKPAK is an oxygen absorber developed to protect packaged foods, pharmaceuticals and other products against spoilage, mold growth, color change, rancidity, loss of nutritive values, insect damage and loss of quality. Produced in packet form using food grade ingredients, OUKPAK irreversibly absorbs oxygen inside sealed packaging to less than 0.01% and maintains this level.
Typical Application
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

OUKPAK Benefits
Extends shelf life
Prevents growth of aerobic pathogens and spoilage organisms, including molds
Eliminates the need for additives such as BHA, BHT, sulfur dioxide, sorbates, benzoates, etc.
Eliminates or reduces the need for preservatives
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
Significantly improves keeping qualities of polyunsaturated fats and oils
Helps retain fresh-roasted flavor 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 mold 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

How to judge
|
|
Perforation
(PET/PAP/PE)
|
Three layers;
Perforate through three layers
|
Can not contact food directly;
Food with shell
|
a. look through the package material under the light, you will see the tiny pore on it;
b. paint the inside layer by greasy pen, you will see the color leak out on the outside layer
|
Leak proof (PET/PAP/PE)
|
Three layers;
Perforate through the upside two layers;
With breathable tiny-pore PE layer inside, prevent the inside material leak out
|
Recommend for food less of grease, direct contact is acceptable;
Oily food with pallet inside that do not contact it directly is acceptable
|
a. look though the package material under the light, no tiny pore can be found;
b. paint the inside layer by grease pen, no color leak out on the outside layer
|
Grease proof (PET/EVA/PAP/PE)
|
Four layers;
Perforate through the upside two layers;
With grease proof paper layer inside
|
Recommend for all food, especially food full of grease;
Can contact food directly
|
a. paint the inside layer by grease pen, no color leak out on the outside layer;
b. dip the oxygen absorber packets in oil at 60 degree centigrade for 10 minutes and take it out, tear the packet, no oil can be found and the powder is as dry as before. Wipe away the oil on oxygen absorber packet and it will keep on reacting.

Package Requirements
OUKPAK 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:
旳dequate 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 OUKPAK. 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.
