Controlling the case throughout the sealing process is the secret to keeping the case square.
Lantech case sealers establish control immediately with adjustable infeed guides that introduce the case into spring-loaded side belts which move in or out to compensate for minor differences in case widths.
The side belts hold the case firmly and transport it through the case sealer. Rollers support the bottom of the case and carry it smoothly through flap folding and sealing.
Our 2 stage front flap folding system first ensures the leading top flap folds at the score line. Stage2 folds the flap perpendicular to the case walls so the top side flaps will be horizontal when they are closed.
The trailing top flap is precisely folded and a plow forces the top side flaps to be horizontal and holds them so they are sealed in that position.
Lantech case sealers preserve the effort and investment you have made in erecting a square case and packing it properly.
