In e-commerce and supply chain management, the shipping box serves as the last line of defense. For brands, the customer’s unboxing moment is where the real product experience begins. A damaged, damp or deformed carton can ruin all your previous marketing efforts in an instant.
With 10 years of deep experience in paper packaging, Hanlong Crafts does not just make simple containers — we specialize in structural mechanics and transport protection. Below is our practical guide to shipping box selection.
This is the most basic choice in logistics packaging. We break down their physical differences:
| Dimension | Folder Carton / Mailer Box | Regular Slotted Carton (RSC) |
| Structure | One-piece forming; self-locking bottom, no tape needed | Folded from one sheet; top & bottom flaps, must be sealed with tape |
| Compression Strength | Medium; relies on paper stiffness and folding structure | High; vertical corrugated & overlapping flaps provide strong load capacity |
| Unboxing Experience | Premium; book-style opening, ceremonial, ideal for D2C | Basic; requires cutter, functional for B2B warehousing |
| Application | E-commerce delivery, small returns, gift boxes, samples | Heavy goods, warehouse stacking, B2B wholesale |
Hanlong Engineer Tip:
Using regular cartons + tape for small items is costly. For parcels under 5kg, the folder carton is the most cost-effective choice.
We provide full-scenario transport protection solutions:
| Box Type | Structural Features | Best For | Hanlong Advantages |
| Standard Folder Box | One-piece, double-tab locking, tape-free | Apparel, shoes, books, small electronics, beauty sets | Reinforced tabs to avoid bursting during delivery |
| Lock-Bottom Folder Box | Interlocking bottom, double load capacity | Heavy small goods, gift sets, fragile items | Anti-burst bottom with reinforcements; no falling apart |
| Regular Carton | Standard flaps, foldable flat | Furniture, industrial parts, warehousing | Optimized burst strength & ECT to prevent stacking collapse |
| Half-Sleeve Box | Inner & outer fitted case like phone boxes | High-value electronics, instruments, gifts | ±1mm tolerance; zero shaking or noise |
| Custom Display Box | Converts to display stand, 2-in-1 | Retail displays, promotions, samples | Easy-tear lines; no tools needed to convert |
