What is triangular packaging?
Triangular packaging uses a triangular cross-section or pyramid shape instead of a standard rectangle. Because most shelves are lined with rectangular boxes, a triangle instantly catches the eye and feels playful or premium depending on the design.
Triangle box styles
The main styles and their uses:
| Style | Shape | Typical use |
|---|---|---|
| Triangular prism | Long box with triangle ends | Chocolate bars, snacks, posters |
| Wedge box | Triangle viewed from the side | Sandwiches, cake slices |
| Pyramid box | Four triangular sides | Favours, sweets, gifts |
| Triangle mailer | Corrugated prism tube | Documents, prints, posters |
Products that suit triangle boxes
Sandwich shops use wedge boxes with windows; chocolatiers use prism boxes; event planners use small pyramids for favours; and artists use triangular mailers to ship rolled prints. Promotional products also benefit from the memorable shape.
Materials
Paperboard suits retail and food packaging and prints beautifully. Corrugated board suits mailers and heavier items. Rigid board creates premium gift versions. Food-safe board and coatings are available for sandwiches and confectionery.
Shelf and shipping considerations
Triangle boxes can pack efficiently when alternated, point up and point down, in shipping cartons and on shelves. Plan the pack-out early so cartons and displays are sized correctly.
Design tips
Use the large sloped faces for branding and the flat base or ends for barcodes and information. A window on one face shows the product. Because faces are angled, keep text away from sharp edges and check readability on a 3D mockup.
Triangle boxes for events
Small triangle and pyramid boxes make memorable favours for weddings, birthdays and corporate events, printed with names, dates or logos.
