Double-slot boxes
The double-slot box is the most common type of cardboard packaging on the market. It has identical slots at both the top and bottom. The process involves die-cutting, printing, gluing, and folding to finalize the box. The design is relatively simple. The double-slot box can be considered the ancestor of cardboard packaging boxes, representing the most primitive box type.

Structural Variants & Intelligent Engineering
Our double-slot folding cartons are designed to deliver excellent rigidity and a great tactile click closure. The two main configurations for these folding cartons to fit your production line are:
Straight Tuck End (STE) Boxes: In this design, both the top and bottom flaps tuck into the box from the exact same side (front-to-back or back-to-front). This creates a clean, uninterrupted silhouette on the front panel—highly preferred for premium cosmetics and high-end tech accessories.
Reverse Tuck End (RTE) Boxes – The top and bottom flaps tuck in from opposite directions. This end style enables best possible use of material in mass industrial die-cutting allowing for the least possible material waste. Consequently it leads to lowest possible per-unit wholesale cost.
Security Slit & Slit-Lock Features: All of our custom retail boxes are cut with special Security Slits in the box slot. These slits lock the tuck flap into place to keep the box from ever coming open unintentionally. This is especially nice for boxes traveling long distances as well as boxes being used in busy retail stores.
Premium Material Selection
A retail box can create an impression of the value of your product through its tactile qualities. We source high quality durable card for your retail boxes. We can source a premium grade of cardstock in a weight that is suited to your target market and price point.
Premium SBS White Cardboard (C1S / C2S): High quality paperboard ranging from 250gsm to 450gsm. This ultra-white, smooth clay-coated paperboard is ideal for premium retail graphics due to its superior color reproduction and printing sharpness.
Kraft Cardstock (Natural Brown / Bleached White) – This earthy Kraft Cardstock is perfect for Eco Friendly brands, Organic Skincare lines and even Artisanal Products. Made from 100% recyclable materials and biodegradable too, it is very strong and is tear resistant.
Black & Specialty Textured Paperboards: The perfect packaging solution for minimalist luxury packaging, allowing for design to stand out without the need for heavy ink coverage. Paperboard offers a beautiful matte finish.
High-End Surface Finishing & Printing Craft
With the aid of our industrial multi-color Heidelberg offset printing machines we transform plain paperboards into marketing masterpieces with refined surface decorations of professional standard.
Drip-Off / Reverse Matte Varnishing : A sophisticated coating technique that applies a rough matte finish to the background of a print and simultaneously renders a specific logo or graphic in high gloss, like a mirror finish.
Spot UV & 3D Raised Coating. This coating draws the eye and fingers of the consumer to the logo or name of the product created as a raised smooth high gloss area against a matte film laminated background.
Precision Foil Stamping: All brilliant metal colors such as Gold, Rose Gold, Silver, and Matte Black as well as multi-dimensional Holographic foils. These papers take the foil perfectly & the foil adheres to the paper fibers and doesn’t flake off.
Embossing & Debossing: The deep and precise industrial die-pressing that lends brand crests and patterns extra depth and high end dimension in premium quality embossed and debossed metal signs.
Crystal-Clear PVC/PET Windows: With precision die-cut slots covered in transparent films, consumers are able to see the product within the rigid box whilst it remains secure.
