Special heat seal dispersions are required to seal glass to aluminum or paper. The hot tack force is particularly critical in this context on account of the uneven surfaces. To improve adhesion, heat seal dispersions can also be thinned and applied as adhesion promoters (cold-end treatment).
These products likewise fulfill all requirements for direct food contact under US CFR 21 FDA, all EU directives and all national regulations applicable in the Federal Republic of Germany and Switzerland.
