Case packer guide: robotic, wrap-around and drop case packers

How case packers work: robotic pick-and-place, top-load, drop and wrap-around case packers, grippers, speeds and how to choose an automatic case packing machine.

Short answer: A case packer places bottles, jars, cans, pouches or cartons into a shipping case. Robotic (pick-and-place) case packers are the most flexible and suit many product sizes; drop packers are simple and fast for robust products; wrap-around case packers form the case around the product group from a flat blank for high-speed beverage and food lines.

Types of case packers

TypeHow it worksBest for
Robotic pick-and-place (top load)A gantry or robot picks a group of products and lowers it into an open caseBottles, jars, pouches, mixed SKUs, frequent changeovers
Drop packerProduct group drops through guides into the caseRobust bottles and cans at high speed
Wrap-around case packerFolds a flat blank around the product group and glues itHigh-speed beverage and food lines with long runs
Side-load / horizontalPushes the group sideways into the caseCartons, trays, bags

Our robotic case packer

The ZX1300-2L two-axis robotic case packer (ZX1300-2L) is a two-axis robotic case packer for bottles, jars, cans, milk powder tins and bags. It handles cases from 200–500 mm long, 150–500 mm wide and 100–500 mm high at 5–20 picks per minute, on a single-phase 220 V supply.

Grippers and change parts

  • Vacuum cups for cartons, pouches and flat-topped tins.
  • Inflatable bladder or mechanical grippers for bottle necks.
  • Dividers or partitions: some products need the case erected with dividers inserted first.

Sizing the case packer

Divide the product rate by the number of products per pick. A filler running 60 bottles per minute packed 12 per case needs 5 cases per minute — well within the range of a two-axis robotic packer. Check the infeed: products should arrive grouped and spaced, often via a lane divider.

The complete case packing area

A typical sequence is NK650 automatic case erector & bottom sealer → case packer → Carton tape sealer (automatic and adjustable) → palletizer. See case erectors, carton sealers and planning an end-of-line packaging system. Send your product, case size and output via the quote form.

Questions and answers

What is a robotic case packer?

A machine that uses a robot or gantry with grippers to pick groups of products and place them into shipping cases. It is flexible for different products and patterns.

How fast is a robotic case packer?

Our ZX1300-2L lists 5–20 picks per minute; each pick can place several products, so the product rate is higher.

What is a wrap-around case packer?

A machine that forms the case from a flat corrugated blank around a group of products and glues it closed, used mainly on high-speed beverage and food lines.

Can a case packer handle pouches?

Yes, with vacuum grippers and suitable infeed. Pouches can be packed standing or lying flat depending on the case.
