Everything Starts with Compatibility
Whether your product is a powder or liquid, film and PVOH compatibility
is critical to unit dose water-soluble packaging success and requires extensive testing.
Find Your Perfect Viscosity
Successful water-soluble pouch products require a consistent density throughout manufacturing and the product’s lifecycle, so that optimum flowability and fill weight can be created (usually between 200 and 600 centipoise).
Beware of Liquid Patents
Certain patents exist in the marketplace that need to be avoided,
which means you need to know the range of allowable water content
in your liquids.
Look Beyond Form Factor
Does your packaging partner offer comprehensive secondary
packaging solutions? Are they experts on moisture barriers and child-resistant safety closures? Do they know the unique shipping specs required of large distributers?
Differentiate Your Brand
Don’t settle for average-looking pouches. If you want to stand out in the marketplace, you need unique solutions such as multi-chamber or dual-layer pouch configurations. Also, consider a combination of both liquid and powder.
