| 1 | Match the box to the product weight | Consider the product weight, dimensions, stacking conditions, and the amount of handling during transport. | Folding carton for light products; corrugated box for heavier or shipped products. | Food productsCosmeticsRetail goodsE-commerce | Use stronger corrugated board when the package must protect the contents during parcel delivery or stacking. |
| 2 | Choose the correct paperboard structure | Paperboard may be solid or made with fluted layers. The structure affects stiffness, cushioning, and compression strength. | Solid bleached board, solid unbleached board, coated recycled board, or corrugated board. | Retail packagingTakeaway packagingShipping cartons | Select single-wall corrugated board for many general shipping applications; use heavier construction when additional protection is required. |
| 3 | Measure the product and allow safe clearance | Record product length, width, and height. Include space for protective inserts, tissue, or cushioning materials. | Mailer box, tuck-end carton, rigid setup box, or die-cut corrugated box. | BooksApparelGiftsSmall electronics | Avoid excessive empty space because it can increase material use and movement inside the package; avoid a tight fit that creates product pressure. |
| 4 | Select the appropriate box style | Evaluate assembly time, opening experience, closure security, and whether the box will be packed manually or automatically. | Tuck-end carton, auto-lock bottom box, mailer box, two-piece rigid box, or sleeve. | Fast packing linesSubscription boxesPremium gifts | Auto-lock or crash-lock styles can reduce taping and assembly steps, while mailer boxes provide integrated closing flaps for shipping. |
| 5 | Consider moisture and product exposure | Check whether the contents may encounter condensation, oil, grease, refrigeration, or humid storage conditions. | Coated paperboard, grease-resistant paperboard, or corrugated board with a suitable functional coating. | Frozen foodsBakery itemsPrepared mealsChilled goods | Paper packaging is naturally absorbent, so moisture-sensitive applications may require a tested barrier treatment and performance validation. |
| 6 | Check food-contact suitability when necessary | For direct food contact, verify that the paperboard, inks, coatings, adhesives, and manufacturing process meet applicable food-contact requirements. | Food-grade folding carton, paperboard tray, or coated food-service box. | Dry foodsBakery productsTakeaway meals | Use a suitable inner liner or barrier when the product is oily, wet, acidic, or in direct contact with the packaging surface. |
| 7 | Balance print quality with material performance | Review surface smoothness, whiteness, color requirements, barcode readability, and resistance to scuffing during handling. | Coated folding carton for detailed graphics; uncoated board for a natural texture and writing surface. | Retail displayBrand-neutral labelsInstructional packaging | Use coated stock for sharper image reproduction and uncoated stock when a tactile, writable, or more natural appearance is preferred. |
| 8 | Design for efficient storage and transport | Compare flat-packed volume, assembled dimensions, pallet utilization, stacking strength, and shipping weight. | Folding carton, flat-pack mailer, or corrugated regular-slotted carton. | Warehouse goodsOnline ordersDistribution packaging | Flat-packed cartons generally require less storage space before use; optimize outer dimensions to reduce unused transport volume. |
| 9 | Review end-of-life and recyclability | Identify plastic films, foil laminates, coatings, adhesives, and other components that may affect recycling in the target market. | Unlaminated paperboard or corrugated packaging designed for established paper-recycling streams. | General retailDry goodsShipping packaging | Prefer simple paper-based structures where product protection allows, and confirm local recycling guidance because accepted materials vary by region. |
| 10 | Test the finished package before ordering in volume | Evaluate compression, drop resistance, vibration, closure strength, print durability, and product fit under realistic conditions. | Any paper box type, including folding cartons, mailers, rigid boxes, and corrugated shipping cases. | Fragile productsLong-distance shippingNew packaging formats | Prototype and test the complete packed package rather than the empty box alone; revise the structure if damage, deformation, or opening problems occur. |
