How to save 30% on shipping costs for paint cans？

When it comes to shipping paint cans, design matters as much as logistics. The shape, size, and structure of a can can make the difference between paying full freight and saving up to 30% in shipping costs.

One of the smartest ways to optimize your design is to create nestable paint cans — cans that can fit neatly inside each other (small can inside big can) during transportation or storage. This “can-in-can” method dramatically reduces unused space and minimizes freight costs.

Below, we’ll explain how to design paint cans that are easy to nest, durable, and compliant with shipping safety standards — so you can save money without sacrificing product quality.

What Is a Nestable Paint Can?

A nestable paint can is designed so that smaller cans can be placed inside larger ones without damaging the lid, body, or coating. This technique is ideal for empty can shipments, where the main cost comes from volume rather than weight.

By carefully adjusting dimensions, rim height, and bottom taper, manufacturers can make cans fit inside each other with minimal clearance — maximizing the number of cans per pallet or container.

➡ Result:
C fits into B, and B fits into A, forming a three-layer nested set.
You can fit 30–35% more cans per pallet compared to standard straight-wall cans.

Lid and Handle Considerations

Nested design doesn’t just affect the body — the lid and handle structure must also adapt.

• Lids:

  • Use flat or low-profile lids instead of domed lids.

  • Consider snap-on lids that don’t protrude above the rim.

  • If using metal lids, design them to lock after nesting (stackable ridge type).

• Handles:

  • Use fold-down plastic or wire handles that lie flat against the body.

  • Avoid fixed upright handles, which interfere with nesting depth.

Material Choices and Surface Treatment

Lightweight and flexible materials perform better for nesting because they absorb impact and avoid deformation.

For export orders, electrostatic or baked coatings can reduce friction and protect against scratching during transportation.

Structural Reinforcement

When cans are nested, the outer can must carry the load of the inner ones.
To prevent deformation:

• Reinforce the upper rim with a rolled or double seam edge.

• Add ribbing lines around the can body for added stiffness.

• For plastic cans, include vertical stiffeners in the mold design.

These reinforcements keep the outer can from collapsing during long-distance shipment.

Packaging Method for Nested Cans

Once your cans are designed for nesting, proper packing ensures safe and efficient transport.

Recommended Packaging Steps:

1. Insert small cans into larger ones using a thin PE liner or paper separator.

2. Stack nested sets into cartons or directly onto pallets.

3. Use stretch film to secure the load (no heavy boxes needed).

4. Label clearly as “Nested Empty Cans – Handle with Care.”

Advantages Beyond Shipping

Designing nestable paint cans not only saves freight costs — it brings additional operational benefits:

• Lower warehouse storage volume

• Easier handling and stacking

• Reduced carbon footprint per shipment

• Simpler export logistics

Manufacturers who adopt nested can designs often report 15–25% cost reduction in total logistics and 30% better storage efficiency.

Frequently Asked Questions (FAQs)

1. Can I design all paint cans to be nestable?
Yes, especially for empty cans. For filled cans, apply only if the paint type and regulations allow.

2. Will nested cans get stuck together?
Not if you design the taper angle (2–5°) correctly and use separators or air vents at the rim.

3. Does the material type affect nesting design?
Yes. Plastic is easier to mold for nesting; metal requires tighter tolerances and stronger rims.

4. What’s the best size difference for nesting?
A height difference of 20–30 mm and diameter difference of 3–5 mm between sizes ensures easy nesting and removal.

5. Can I ship nested cans internationally?
Absolutely. Most exporters use nested empty cans to save container space — it’s fully compliant for non-hazardous products.

6. How much cost can I save with nested design?
On average, 15–35% shipping cost reduction depending on container utilization and transport mode.

Final Thoughts

Designing nestable paint cans isn’t just an engineering tweak — it’s a business advantage. By planning the can dimensions, angles, and materials for nesting, you can ship more cans in the same space, cut freight costs, and lower environmental impact.
