Jar front and back labelling machine

When jars need front and back labels

Many jars use wrap-around labels, but front and back labels are useful where the brand panel and ingredient panel need to be separate. This can apply to food jars, cosmetic jars, supplements and specialist products.

The jar shape, diameter, lid size and label panel determine whether front/back placement or wrap-around labelling is the better route.

• Separate front branding and rear information labels.
• Partial labels on round jars where wrap-around is not desired.
• Panelled jars that need label placement within a defined area.

Container control for jars

Jars can be stable because of their wider base, but smaller jars, lightweight plastics and tapered containers still need checking. The labeller must present the jar consistently to both label heads.

For round jars needing two separate labels, the method of controlling orientation and label spacing should be reviewed.

• Measure jar diameter, height and label panel.
• Check if the jar is round, oval, square or tapered.
• Confirm if filled weight helps or hinders stability.

Label material and finish

Paper, film and clear labels can all be used on jars, but material choice affects sensor selection and wipe-down. Food or chilled jars may also create moisture considerations.

Where labels include barcode, nutritional information or ingredients, accuracy and repeatability become more important.

• Confirm label stock and adhesive suitability.
• Send front and rear label dimensions.
• Flag chilled, wet or oily conditions around the labeller.

Choosing the labelling route

A compact twin side labeller can suit small-batch jar labelling and product trials. An automatic twin-side system is more suitable for continuous production or connection to filling, capping and coding equipment.

• Compact route for lower-volume projects.
• Automatic route for inline or higher output production.
• Top/bottom route for flat tubs, sleeves or cartons rather than jar sides.
