Migration limits of contaminants from polymers into a food product have been imposed, and independent testing and certification of component materials is required to ensure these regulations are satisfied. Stringent manufacturing and warehousing conditions as well as special packaging procedures are also required to eliminate other sources of contamination.
The constituent materials have been chosen for their purity, giving low levels of migration and ensuring consistent high quality and performance.
Combined with our positive Polyloc sealing (polypropylene or polyester) welded ring, needlefelt food grade filter bags have a fully welded construction as standard and are 100% bypass free.
The external surface of the filter bag is calendered or signed, eliminating ant possibility of fibre migration into the filtrate. Each bag may be individually wrapped.
