Straight line cartons

A straight line carton is the most commonly used folding carton style. The carton is glued along a single seam, supplied flat, and erected by the customer or their packing line. The top and bottom tucks fold in the same direction, making them simple to close and reliable in use.

They're a practical, no-fuss choice for a wide range of products. Where other carton styles add complexity, straight line cartons keep things simple and consistent.

Straight line cartons suit products across almost every sector. Common applications include:

• Supplements and nutraceuticals (bottles, tubs, sachets)

• Cosmetics and personal care

• Food and drink

• Pet care

• Vaping and e-liquid hardware

• Pharmaceutical and healthcare

Their simplicity makes them well suited to automated packing lines as well as manual fulfilment.

Straight line cartons offer a reliable combination of practicality and economy. Because they're glued along one seam and erect cleanly, they work well with automated erection and packing equipment. They store flat, which helps with warehouse space, and can be shipped efficiently.

They also have a presentational advantage over reverse tuck end cartons that's easy to overlook: because both the top and bottom tucks fold towards the back of the carton, the flap edges are completely hidden when the carton is viewed from the front. The result is a cleaner, neater face panel with no visible tuck lines. For retail or shelf-facing products, that matters.

Full-colour digital print with premium options

All our folding cartons are digitally printed in-house on the same HP Indigo presses we use for our labels. This means:

• No printing plates, so no origination costs and no penalties for updating artwork

• Excellent colour accuracy and consistency from run to run

• Short runs and multiple SKUs handled efficiently

• Colour matching with your label is straightforward, even accounting for the difference in substrate

We can print onto board up to 450 micron, covering a wide range of carton weights. Finishing options include:

• Hot foil stamping in metallic, day-glo, and holographic finishes

• Cold foiling applied digitally, with design variation possible from SKU to SKU at no additional setup cost

• Embossing and debossing for a tactile, three-dimensional finish

• Screen printing for high-build spot varnishes, opaque whites, and special effects

• Digital varnish with no origination costs, available flat or raised

• Overlaminates in gloss, matt, or soft touch

Because we print both labels and cartons on the same digital presses, colour matching between the two is reliable, even accounting for the natural differences between label and carton substrates.

Straight line cartons offer a clean front-facing appearance, combined with a wide range of print and embellishment options.

Whether you need a straightforward carton done well, or a fully finished retail pack with foil and embossing, we can produce it.
