Promotional Boxes with crash lock base

Crash Lock Boxes Printed With Your Designs

If you're after packaging that’s easy to store and quick to assemble, our Crash Lock Boxes are a perfect choice. Made from sturdy paperboard, they’re durable, long-lasting, and arrive flat-packed to save on storage space.

Each box features a crash-lock base that clicks into place—no glue or tape needed, making assembly fast and hassle-free.

You can fully customise these boxes with your branding, making them ideal for promotional use at trade shows, events, in-store giveaways, or pop-up stalls. With a range of sizes available, it’s easy to find the right fit for your product or campaign.

Personalise Your Look

Want to elevate your packaging even further? Add one of our lamination options to give your boxes a premium look and feel, while also adding a layer of protection:

• Matt – A matt finish that reduces glare and fading over time. (Note: only permanent markers can be used on laminated surfaces.)

• Gloss – A high-shine finish that enhances colour vibrancy and detail.

• Soft Touch – An ultra-matte finish with a smooth, velvety feel for a sophisticated, high-end look.

Material Options

Choose from our high-quality materials, each with its unique finish:

• 380gsm Technodesign (SBS Paperboard) – Solid Bleached Sulphate board known for its excellent print quality and smooth finish. Odour-free and ideal for cosmetic or fragranced products.

• 400gsm Classic Demimatt – Coated on both sides for sharp image reproduction and enhanced durability. Its slight elasticity helps prevent tears or cracks.

• 380gsm Brown Card – Made from 100% recycled pulp. The smooth surface provides great printability and supports a sustainable look.

• 300gsm Premium Card – A high-quality, pure cellulose card with a dual-sided textured treatment for sharp, vibrant print results.

• 300gsm Embossed Card – A natural cellulose card with a rough texture and soft ivory tone, perfect for a more organic or artisanal finish.
