OUR COMPANY MAKE PACKAGING FOR PRODUCTION AND EXPORT THEM TO THE FOREIGN COUNTRY. WE NEED WELL
-BALANCED WORKERS IN THIS FIELD. Barrier protection – A barrier to oxygen, water vapor, dust, etc. is often required. Permeation is a critical factor in design.
Some packages contain desiccants or oxygen absorbers to help extend shelf life.
Modified atmospheres or controlled atmospheres are also maintained in some food packages.
Keeping the contents clean, fresh, sterile and safe for the duration of the intended shelf life is a primary function.
A barrier is also implemented in cases where segregation of two materials prior to end use is required, as in the case of special paints, glues, medical fluids, etc.
At the consumer end, the packaging barrier is broken or measured amounts of material are removed for mixing and subsequent end use.
