Introduction
Not all corrugated boxes are the same. The style (or design) of a box determines how it's assembled, how products are loaded, and what protection it offers. Choosing the right box style can reduce your packaging cost, improve packing line efficiency, and provide better product protection.
Here's a detailed guide to every major corrugated box style used in Indian industry.
1. RSC — Regular Slotted Container
The RSC is the most common corrugated box used worldwide. It's manufactured from a single sheet of corrugated board with flaps on the top and bottom.
How It Works
- All four flaps are the same length
- The outer flaps meet at the centre when folded (or overlap, depending on design)
- Sealed with tape, staples, or adhesive
Specifications
- Available in 3-ply, 5-ply, and 7-ply
- Any custom dimensions
- Can be printed up to 4 colours
Best For
- General shipping and storage
- E-commerce fulfilment
- FMCG product packaging
- Industrial component shipping
Advantages
- Lowest manufacturing cost
- Flat-packed for efficient storage
- Simple to assemble — no special equipment needed
- Versatile — suits almost any product
Limitations
- Not ideal for very heavy items without additional reinforcement
- Doesn't provide a premium unboxing experience
- Flap gaps can allow dust ingress
2. Die-Cut Boxes
Die-cut boxes are precision-cut from a single sheet using a custom steel die, allowing for complex shapes, fold patterns, and exact-fit packaging.
How It Works
- A custom die (steel cutting template) is created for your box shape
- The corrugated sheet is cut and creased in one operation
- Boxes can have auto-locking tabs, display windows, and curved features
Best For
- Exact-fit product packaging (electronics, cosmetics, gifts)
- Retail shelf-ready packaging
- Products with unusual shapes
- Mailer boxes for D2C brands
Advantages
- Precise fit reduces need for void-fill
- Professional appearance for retail
- Self-locking designs speed up packing
- Can include built-in product holders and partition features
Limitations
- Higher per-unit cost (die creation + setup)
- Die cost is a one-time investment (₹3,000–₹15,000 depending on complexity)
- Not economical for very small quantities
3. Telescopic Boxes
A telescopic box consists of two separate pieces — a top (lid) and a bottom (tray) — that "telescope" over each other.
How It Works
- The lid slides over the base
- When closed, the two pieces overlap, providing double-wall protection on the sides
- Available as full-telescope (lid covers full height) or half-telescope
Best For
- Heavy or fragile products
- Products requiring easy inspection (the lid lifts off)
- Garments and textile packaging
- Premium product packaging
Advantages
- Excellent stacking strength (double-wall effect on sides)
- Easy open/close — no tape cutting needed
- Reusable for storage
- Professional presentation
Limitations
- Higher material cost (two separate pieces)
- Requires more storage space as two parts
- Slightly slower to assemble
4. Crash Lock Bottom (Auto-Bottom) Boxes
These boxes have a pre-glued bottom that automatically "crashes" or locks into place when the box is opened — no taping of the bottom needed.
How It Works
- The bottom panels are pre-folded and glued during manufacturing
- When you push open the box, the bottom panels lock into a flat, rigid base
- You only need to fold and tape the top flaps
Best For
- High-speed packing lines
- E-commerce fulfilment centres
- Food packaging
- Any application needing fast assembly
Advantages
- Fastest assembly time — saves 5–10 seconds per box on a packing line
- Stronger bottom than a standard RSC
- Reduces packing errors
- Lower labour cost at scale
Limitations
- Slightly higher per-unit cost due to pre-gluing
- Less flexible — each size needs its own specification
- Requires precise manufacturing
5. Mailer Boxes
Mailer boxes are one-piece boxes with a tuck-in flap that creates a clean, brandable exterior. They're the go-to for D2C brands.
How It Works
- Single piece of corrugated board
- Front panel tucks into the box to close it
- Can be printed on both exterior and interior surfaces
Best For
- Subscription boxes
- D2C e-commerce brands
- Gift packaging
- Cosmetics and beauty products
- Books and media
Advantages
- Premium unboxing experience
- Excellent for full-colour printing and branding
- Flat storage before use
- No tape needed (tuck closure)
Limitations
- Higher cost than RSC
- Die-cutting required
- Not suitable for very heavy items
6. Octabin / Heavy-Duty Boxes
Octabins are large octagonal corrugated containers designed for bulk packaging of powders, granules, and heavy industrial materials.
How It Works
- Eight-sided (octagonal) construction
- Made from 5-ply or 7-ply corrugated board
- Often includes plastic liner bags for powder/granule containment
- Palletizable for forklift handling
Best For
- Chemical powders and granules
- Food ingredients (flour, spices, grains)
- Industrial raw materials
- Agricultural produce in bulk
Advantages
- Very high volume capacity (500–1,500 litres)
- Strong compression resistance
- Replaces wooden crates and metal drums — lighter and recyclable
- Cost-effective for bulk shipping
Limitations
- Requires specialised manufacturing equipment
- Not suitable for small products
- Needs pallet handling
7. Partition Boxes
Partition boxes contain internal dividers that separate multiple products within a single box.
How It Works
- Standard outer box (usually RSC) with interlocking cardboard dividers inside
- Dividers can be slotted, die-cut, or simply folded strips
Best For
- Bottles, jars, and glass items
- Electronic components
- Hardware and fasteners
- Cosmetic sets and gift packs
Advantages
- Prevents products from touching and damaging each other
- Eliminates need for individual wrapping
- Professional presentation
- 100% recyclable (no foam or plastic)
