Custom A3 cartons – because appearance enhances what's inside

Customization makes a brand and its parcels instantly recognizable. Colors, prints, or illustrations evoke anticipation and create an emotional connection with the product before it's even opened. This engages the senses and creates a unique shopping experience that goes beyond the transaction—connecting the customer to your brand long-term.

At Boxmarket, we offer the ability to tailor A3 boxes to your individual needs through unique customizations. Our options include:

• Logo or graphic printing
• Choice of color and finish
• Custom dimensions for non-standard products
• Complete packaging design from concept to production
• Modification of existing designs

How to choose the right A3 carton?

An A3 carton is not just a one-size-fits-all product. Here are some key factors to consider when ordering:

• Cardboard thickness – single-wall boxes are enough for light items, while multi-wall versions are better for heavier loads.
• Closing method – flap boxes require tape, while die-cut ones often feature built-in closure mechanisms.
• Load capacity and crush resistance – for heavier use, choose models with higher grammage and durability.
