Cannabis Labeling Machines for Pouches, Jars and Pre-Roll Tubes

Every cannabis package needs a compliance label, and most need a new one for every batch. Applying them by hand is slow and the placement drifts. This guide covers the machines that do it for pouches, jars and pre-roll tubes.

Pouches

Pouches are the hardest package to label because they are soft and filled bags are not flat. The Flat Pouch Labeler labels stand-up and zipper pouches at 20 to 60 a minute, depending on the product and the label size. Placement is accurate to 1 mm. It is built in Germany with an IP65 rating for dust and water.

You can label pouches before filling or after. Labeling empty bags is easier because they lie flat. Labeling after filling means the batch label goes on the exact product it describes. Most lines place the labeler right after the bagger.

Jars and bottles

Round containers get a wrap label. The Round Container Labeler handles jars and bottles from 30 to 100 mm across and up to 200 mm tall, at up to 60 a minute. It keeps the jar and the label moving at the same speed so the label goes on straight.

Pre-roll tubes

Tubes are small and light, so they need their own machine. The Pre-Roll Tube Labeler places labels within 1 mm and will not apply a label if there is no tube, which stops labels from sticking to the machine.

What to check on your labels

• Rolls, not sheets. Machines run labels on a roll. Ask your printer for the core size and roll diameter the machine takes. The Flat Pouch Labeler takes a 76 mm core and rolls up to 350 mm across.
• Label size. Check the minimum and maximum label size for the machine before you design the label.
• Gap and direction. The gap between labels and the direction they come off the roll must match the machine. Send the label spec to us before you print a large run.
• Variable data. Batch numbers, dates and test results change every run. Decide whether they are printed on the label ahead of time or printed inline.

Where the labeler sits in the line

A labeler is only as fast as the machine before it. Match its speed to your bagger or jar line. On a pouch line the order is usually weigher, bagger, labeler, then a checkweigher.
