The stitched-bead pattern is how InvisiPac's 30%+ adhesive-usage-reduction claim is actually realized on the line — running an InvisiPac head without a PC-8 pattern controller defaults to a solid bead and forfeits that material savings.
The stitched-bead pattern PC-8 produces is literally how InvisiPac's 30%+ adhesive-usage-reduction claim gets realized on the case-sealing line. Running an InvisiPac head without a PC-8 pattern controller means defaulting to a solid bead and giving up the material savings the system was specified to deliver.
