Slotted-type cardboard boxes consist of basically one piece of corrugated board with a glued, stitched or taped manufacturer’s joint and top and bottom flaps. They are shipped flat (knocked down), ready to use and require closing using the flaps provided. The bottom of the box requires sealing before use and is easily sealed with adhesive packaging tape, carton box sealer, hot melt adhesive or staples.

These corrugated containers do not require a cutting form and can be manufactured quickly, making the one of the most cost effective storage, shipment and packaging products.

• Q:In what order does a flexo folder-gluer perform its operations? A:Typically, a flexo folder-gluer performs its functions in the following order: blanks are fed one at a time; printed with one or more ink colors; scored, slotted and trimmed; glued and folded; and counted and stacked.
• Q:How are the sheets of corrugated board fed one at a time into a flexo folder-gluer? A:Blanks can either be pushed or pulled into a flexo folder-gluer using a kicker-type feeder, a suction-type feeder, or a combination. Feed (or pull) rolls accelerate each blank as it enters the machine to create the required spacing between the blanks.
• Q:When more than one color is to be printed, how is the order of application determined? A:Because the inks are somewhat transparent and the printed surface becomes less and less absorptive, darker colors are usually printed first and lightest colors last.
• A:Why is it important to continuously agitate flexographic inks, even during short down times? Q:Flexographic inks tend to thicken as they are agitated until they reach a stable viscosity. Continuous agitation maintains their viscosity and and also avoids drying of the inks in the pans and circulating systems.
• A:WhyHow can adjustments and maintenance be performed on the different sections of a flexo folder-gluer? is it important to continuously agitate flexographic inks, even during short down times? Q:Rollout and rollaway models allow for easier access to the sections. In rollout machines, the printing and die cutting sections can be rolled out to the side, while in rollaway machines, the sections are mounted on rails and remain inline when they are separated.
