What is the Bloom Seal ® treatment for plastics?
Through a surface reaction with Bloom Seal ®, a thin PTFE barrier layer can be created on surfaces of polyolefin articles. This layer imparts outstanding hydrocarbon solvent barrier and consequently has found growing uses in packaging and other industries. This barrier greatly reduces the permeation and scalping of a range of fuels, chemicals, solvents, flavours and fragrances. Container softening and/or swelling can be reduced in many cases and long term panelling through weight loss of product can often be brought down to an acceptable level. Bloom Seal ® effectively extends the application bounds of polyethylene containers and tankage. This allows inexpensive polyethylene to be used in applications with aggressive chemicals, such as with agricultural chemicals, solvents, institutional/industrial cleaning formulations, food, pharmaceuticals and cosmetics etc., where an untreated container would have marginal success in containing the product.
