Custom 15×15×150 mm two-flap box

The 15×15×150 mm two-flap box is a compact cardboard package for products that need a close fit and a polished retail presentation. This version has proportions best described as a very slim and elongated vertical format. It is particularly useful for items such as slender cosmetic applicators, sample vials, styluses, craft tools and other long narrow accessories. Top and bottom closing flaps make packing straightforward, protect the contents during display and help a complete product range maintain a consistent appearance.

Choose the 15×15×150 mm format from the actual dimensions of the item rather than its commercial name alone. Leave a small practical allowance inside so that the product can be inserted and removed without bending the panels. If the contents have an irregular outline, projecting parts or an additional wrap, include them before the dieline and artwork are approved.

Applications and packing method

The package layout can be described as a narrow sleeve-like carton with a long branding panel. These proportions reduce unnecessary empty space and hold a small item more effectively than an arbitrary carton. The box can serve as individual retail packaging, a protective unit inside a gift set, an inner carton placed in a larger shipping package or an organised element of a shelf display.

The two closing flaps sit at opposite ends of the structure. Once folded, they provide convenient access without requiring a separate lid. Depending on product weight, board type and transport conditions, the construction may use a glued side seam and additional flap security. The carton itself does not replace cushioning when an item is fragile, heavy or especially sensitive to impact.

Cardboard selected for the product

The material affects rigidity, colour reproduction and the overall character of the package. White coated board provides a clean background, sharp typography and predictable image printing. Matt board feels more restrained, kraft supports a natural or craft-led identity, and selected designer stocks can introduce texture and a more individual premium finish. The exact choices available depend on the calculator and order specification.

On a small box, even a modest change in board thickness influences folding. Material that is too soft may not retain the intended shape, while an unnecessarily rigid stock can make small flaps difficult to close correctly. Select the substrate together with the dimensions, content weight, run length and expected handling rather than treating it as a separate decorative decision.

Printed design and branding

A 15×15×150 mm box can carry a logo, product name, variant, ingredients, instructions, batch reference, manufacturer details, barcode or QR code. Space is limited, so the layout needs a clear hierarchy. The main message should remain readable from a normal viewing distance, while smaller technical information belongs on a panel that is not crossed by a crease or hidden beneath a flap.

A consistent graphic system makes it possible to use the same construction for several product variants. Colour, naming or a small symbol can distinguish each version while the logo and information layout remain common. This improves recognition, helps customers compare the range and makes even a very small item feel like part of a considered collection.

Preparing print-ready artwork

Create the design on the correct production dieline with the required bleed and safe margins. Backgrounds that reach an edge must extend beyond the cutting line, while text, logos and codes must stay clear of cuts, creases and gluing areas. Do not rescale the template or move structural elements unless the change has been agreed before production.

Vector files are preferable for logos and line graphics. Embed fonts or convert them to outlines, and provide raster images at adequate resolution at final size. Extremely thin strokes, tiny lettering and weak contrast may lose clarity in print. Test QR codes and barcodes at their actual dimensions and preserve the required quiet area around them.

Finishing and colour expectations

Depending on the selected configuration, the box may be finished with matt or gloss lamination. Lamination improves resistance to ordinary scuffing and moisture but does not make cardboard waterproof. Matt reduces reflections and creates a quieter surface, while gloss can make colour appear more saturated. Choose finishing to suit the artwork, product and budget instead of adding it automatically.

A screen is not an exact print proof. File settings, printing method, substrate and finishing all affect the result. Important brand colours should be defined during artwork preparation. On kraft or coloured board, unprinted areas retain the colour of the material, and printed colours may appear darker or less intense than they would on a white surface.

Checks before ordering

Before selecting the 15×15×150 mm box, measure the product in three directions, check how it will be inserted and include any leaflet, bag, film or internal support that must fit inside. For a larger run, it is sensible to verify the structure with a sample or a simple unprinted mock-up. This confirms fit, folding sequence and closing comfort before the full quantity is produced.

Technical file review covers basic production parameters but does not replace editorial proofreading. The customer should confirm names, ingredients, contacts, batch details, codes and required legal markings. These elements are printed from the approved artwork, so inspect the final PDF at 100% scale and approve it only after a careful content check.

Frequently asked questions

What suits the 15×15×150 mm format?

It is best considered for products similar to slender cosmetic applicators, sample vials, styluses, craft tools and other long narrow accessories. Final suitability always depends on the actual dimensions, shape and protective wrapping of the specific item.

Is the box supplied flat?

Delivery format depends on the production method and agreed specification, although cardboard cartons of this type are generally efficient to store and transport before assembly. Confirm the details when ordering.

Can every outer panel be printed?

Yes. Artwork can cover the external panels shown on the dieline, provided that gluing, cutting and creasing zones and any areas hidden after assembly are taken into account.

Can I supply my own design?

Yes. Upload artwork prepared on the current production template. Its basic technical parameters will be checked before printing.
