How can I stop windows flying off at high
speeds?
Some machines bend the envelope immediately after
gluing the window. When machines run at high speeds the windows do not
have time to bond properly. A modified window patch adhesive is
required. Contact Us
How do I overcome splashing of adhesive at
high machine speeds.
Stencil applied adhesives can splash at the high
speeds of today’s machines. Careful formulation of the adhesive is
required to overcome this. Pafra’s envelope range includes high speed
side seam products. Contact Us
How do I prevent skinning of the flap gum?
All flap gums skin over time, however it is not a
problem provided the skin does not become detached from the tray
sides. It actually helps reduce thickening of the adhesive below the
skin.
