Introduction

In the FMCG industry, corrugated boxes are far more than simple transport containers—they are critical to product protection, logistics efficiency, and cost optimization.

A poorly designed shipper can lead to:

• damaged products

• inefficient pallet utilization

• increased freight cost

While a well-designed corrugated box can significantly improve supply chain performance.

This guide breaks down:

• types of corrugated boxes used in FMCG

• how to select the right type

• how to calculate box dimensions

• a real example using a 200 ml round bottle

📦 Types of Corrugated Boxes in FMCG

1. Regular Slotted Container (RSC)

The most widely used corrugated box in FMCG.

Key Features:

• All flaps are equal length

• Flaps meet at the center

• Side seam is glued or stitched

Used for:

• shampoo bottles

• cleaning products

• cartons and pouches

Why it works:

• cost-effective

• easy to manufacture

• suitable for automation

2. Half Slotted Container (HSC)

An open-top version of RSC.

Used for:

• trays for shrink-wrapped packs

• retail display trays

Advantage:

• easy product loading

• ideal for shelf-ready formats

3. Full Overlap Carton (FOL)

Flaps fully overlap at top and bottom.

Used for:

• glass bottles

• heavy jars

• export shipments

Advantage:

• higher stacking strength

• better impact resistance

4. Die-Cut / Shelf-Ready Packaging

Custom-designed corrugated structures.

Used for:

• retail display

• cosmetics and premium FMCG

Advantage:

• faster shelf replenishment

• better visibility

5. Partitioned Corrugated Boxes

Boxes with internal dividers.

Used for:

• glass bottles

• sauces and beverages

Advantage:

• prevents product collision

• reduces breakage

How to Select the Right Box

Choosing the right corrugated box depends on:

1. Product Characteristics

• fragile vs durable

• rigid vs flexible

• liquid vs solid

2. Distribution Conditions

• local vs long-distance

• warehouse stacking

• export shipping

3. Handling & Storage

• manual handling

• pallet stacking

• humidity exposure

4. Retail Requirements

• shelf-ready vs transport-only

• display needs

📐 How to Calculate Corrugated Box Size

Corrugated boxes are defined as:

Length × Width × Height (L × W × H)

These are typically internal dimensions

📊 Standard Formula (RSC)

Internal Dimensions:

• L = (a × product length) + clearance

• W = (b × product width) + clearance

• H = (c × product height) + allowance

Outer Dimensions:

• OL = IL + 2 × board thickness

• OW = IW + 2 × board thickness

• OH = IH + 2 × board thickness

📦 Example: 200 ml Round Bottle

Let’s apply this to a real FMCG scenario.

Product Details

• Bottle diameter = 50 mm

• Bottle height = 150 mm

Pack Configuration

• 12 bottles

• Arrangement: 4 × 3 × 1

Assumptions

• Clearance = 10 mm

• Board thickness = 5 mm

Step 1: Internal Dimensions

Length (L)= (4 × 50) + 10= 210 mm

Width (W)= (3 × 50) + 10= 160 mm

Height (H)= (1 × 150) + 10= 160 mm

👉 Internal Size = 210 × 160 × 160 mm

Step 2: Outer Dimensions

Length (OL)= 210 + (2 × 5) = 220 mm

Width (OW)= 160 + (2 × 5) = 170 mm

Height (OH)= 160 + (2 × 5) = 170 mm

👉 Outer Size = 220 × 170 × 170 mm

🧩 Partition Consideration (Optional)

For fragile bottles:

Honeycomb / divider cell size:

• approx 50 × 50 × 150 mm per bottle

This ensures:

• no bottle contact

• improved transit safety

📦 Key Design Insights

1. Avoid Oversizing

• reduces pallet efficiency

• increases shipping cost

• lowers stacking strength

2. Avoid Tight Fit

• difficult packing

• risk of deformation

• line inefficiencies

3. Design for Pallets

Always check:

• cases per layer

• pallet height

• load stability

🚚 Storage & Distribution Considerations

Corrugated performance is influenced by:

• humidity

• stacking duration

• transport vibration

• load distribution

A box that works in production may fail during distribution if these are ignored.

Think System, Not Box

Corrugated design should align with:

• product geometry

• case configuration

• pallet optimization

• distribution route

👉 It’s not just packaging—it’s supply chain engineering

✅ Conclusion

In FMCG, corrugated boxes play a critical role in:

• protecting products

• optimizing logistics

• reducing overall cost

The most widely used format remains the RSC, but the final design should always be based on:

✔ product✔ distribution✔ stacking✔ pallet efficiency

📌 Packaging Decoded Insight

Small changes in box design—just a few millimeters—can lead to significant cost savings across the supply chain.
