The materials used in the building industry are mostly water based component mixtures.
The use of water soluble films, preformed sachets, stretch sticky film for fibbers wrapping allowing an easy and precise dosing of the additive components in the mix.
In addition the PVAL is a fully compatible component to these mixtures and act as a binder.
The fiber packs created with the sticky stretch film allow a dosing accuracy that can be directly introduced into the tank mixing. The film creates a water soluble envelope sticking to itself thus no need for heat sealing is required.
