Gluing
Our gluing service turns die cut printed sheets into assembled cartons, sleeves and folded packaging ready for packing or despatch. We handle commercial packaging work from Durban for clients across KwaZulu-Natal and the rest of South Africa.
What Our Gluing Service Includes
Gluing is the stage where a flat, die cut carton is folded and bonded along its glue flap so it arrives as a usable pack format. This is used for straight line cartons, sleeves, crash lock styles, display outers and selected point of sale packs. We match the gluing method to the board grade, carton shape and intended packing line, so the finished work opens properly and stays square.
Our workshop handles gluing as part of a full finishing process after printing and die cutting. That means we can check fold lines, panel alignment and bond position before the cartons are packed out. For retail packaging and promotional cartons, that practical control matters because a small shift on the glue line can affect how the whole pack closes.

- Batch packing, bundling and despatch preparation
How The Gluing Process Works
We start by reviewing the die line, board thickness and fold direction to make sure the carton design is suitable for gluing. From there the die cut blanks are checked for clean cut edges, accurate creases and waste removal. If needed, we confirm a sample fold before a full run goes ahead.
The glue is applied to the marked flap area only, then the blank is folded into shape and pressed for bond strength. Drying or curing time depends on the board surface and carton construction. Once the bond has settled, cartons are counted, bundled and packed for either onward filling or national delivery by despatch.
- Artwork and structural layout checked against the final die line
- Die cut blanks inspected for clean cuts and even creasing
- Glue area confirmed to avoid squeeze out onto visible panels
- Folding and bonding completed to the approved carton shape
- Finished cartons checked, packed and labelled by batch
In Durban and coastal parts of KwaZulu-Natal, humidity can affect board behaviour and drying times, so we plan handling and packing carefully. During periods of power cuts we sequence finishing work to keep turnaround practical and avoid cartons sitting open too long before packing.
What Clients Need To Prepare
The best gluing results start with a packaging layout that has been prepared properly. Clients should supply approved artwork, a final cutter guide or die line, clear dimensions and details on how the carton will be filled and closed. If the pack is for retail shelves, courier packing or food outer use, tell us how it will be handled so we can flag any obvious structural concerns early.
It also helps if you confirm whether the carton must ship flat, semi assembled or fully formed. Some clients need glued cartons only, while others need us to combine printing, die cutting, gluing, folding and packing in one job. A quick sample or mock-up is useful, especially for new carton sizes or promotional sleeves.
- Final approved artwork with bleed and safe areas allowed for
- Accurate flat size, folded size and board specification
- Die line showing crease positions, cut lines and glue flap
- Quantity split if there are multiple versions or regional packs
- Instructions for bundling, labelling and delivery points
Typical Cartons And Packaging We Glue
Most gluing jobs fall into everyday commercial packaging formats used by shops, product distributors and event suppliers. These include tuck cartons, sleeves for boxed goods, counter display outers, folded promotional packs and carton components used with inserts. We also handle selected point of sale packaging where the print finish and fold quality must still look neat once assembled.
Where a job includes litho, digital or flexographic print beforehand, we pay attention to ink coverage and surface finish in the glue area. Heavy coating, laminating or certain varnishes can affect adhesion, so this should be confirmed before production. If a design has windows, unusual angles or very small panels, we may recommend a test sample first just to keep things right.
For larger despatch runs, cartons are bundled in practical pack sizes for counting and handling. This keeps the packs cleaner in transit and helps receiving teams sort stock faster on arrival, which clients often appreciate.
How Gluing Is Costed
Pricing is worked out from the carton style, flat size, board type, glue application, run quantity and how much handling the job needs before and after bonding. Simple straight line cartons are usually more straightforward than crash lock styles or display units with more folds and touch points. The total also depends on whether the work arrives already printed and die cut, or whether we are handling the full print and finishing sequence.
Packing method matters too. Bulk packed cartons, counted bundles, labelled outers and split deliveries all add handling time. If samples, make readies or trial folds are needed before the main run, those are also considered when we prepare your quote. For accurate pricing, send the die line, quantity and delivery requirement through the enquiry form on our contact page.

- Board thickness and surface finish
- Glue line length and bonding method
- Run size and number of versions
- Packing format and delivery destination
Packing, Delivery And Aftercare
Once cartons are glued, we pack them to suit transport and storage. Flat packed glued cartons must stay dry, clean and square, so they are bundled and boxed in a way that limits edge damage and shifting during despatch. We arrange delivery from Durban into KwaZulu-Natal and across South Africa using practical transport options based on carton volume and destination.
After delivery, keep cartons in a dry indoor area away from direct heat and floor moisture. Let the cartons settle to room conditions before heavy filling runs, especially if they have travelled between inland and coastal climates. Avoid stacking too high on weak corners, and do not place weight directly on packs with windows or unusual cut-outs. If there is any concern about opening performance or glue bond on receipt, contact us through the enquiry form and we can review the batch details.
Good storage makes a real difference. Board can move slightly with moisture in the air, and that can affect how neatly a pack opens if it has been left in poor conditions for too long.

Questions we get asked
Can you glue cartons that were printed elsewhere?
Yes, provided the blanks are suitable for finishing and the die cutting, creasing and coating allow proper adhesion. We may ask to inspect a sample first.
Do all cartons need a sample before production?
Not always. Standard carton styles can often move straight into production, but new shapes, coated stocks or unusual folds are better checked with a test sample.
Will glued cartons be delivered flat or assembled?
Most carton work is supplied flat packed after gluing to save space and protect the packs in transit. If a job needs partial assembly or special packing, include that in your enquiry.
