When ordering custom packaging, one of the most critical decisions you’ll face is choosing the right box thickness. Select a material that’s too thin, and your product may arrive damaged. Choose something unnecessarily thick, and you’ll overpay for materials and shipping.

At PackagingVista, we help Los Angeles businesses navigate these decisions daily. This guide explains box thickness in simple terms, helping you make an informed choice that balances protection, presentation, and cost.

Understanding Right Box Thickness: Two Different Systems

Box thickness is measured differently depending on whether you’re using paperboard (retail boxes) or corrugated (shipping boxes).

Paperboard Thickness: Measured in Points (pt)

Paperboard, also called folding carton, is measured in “points,” where one point equals 1/1000th of an inch. The higher the point, the thicker and more rigid the board.

GradeThicknessBest Applications

12pt – 14pt Very thin Product inserts, lightweight inner packaging, budget-conscious retail

16pt Thin Cosmetic boxes, small retail items

18pt Standard Most retail boxes, food packaging, electronics, general merchandise

20pt – 24pt Heavy Luxury goods, gift boxes, premium cosmetics, high-end spirits

24pt+ Extra heavy Rigid box construction, premium presentation cases

When to Choose Paperboard:

• Your product is lightweight.
• The box will sit on a retail shelf (not shipped alone)
• You need high-quality printing with vibrant colors.
• You want a folding carton style for easy storage and assembly.

Corrugated Thickness: Measured by Flute Type

Corrugated boxes consist of three layers: an outside liner, an inside liner, and a fluted middle layer. The “flute” determines the box’s strength, cushioning, and printability.

Flute Type, Thickness, Strength, Print Quality, Best Applications

E-Flute 1.5mm (1/16″) Low to Medium Excellent Retail displays, pizza boxes, smaller e-commerce mailers

B-Flute 3mm (1/8″) Medium Good Standard shipping boxes, e-commerce packaging, subscription boxes

C-Flute 4mm (5/32″) High Fair Heavy items, industrial shipping, fragile product protection

Double Wall (BC, BE) 6-7mm Very High Limited Extremely heavy items, machinery, international shipping

When to Choose Corrugated:

• Your product will be shipped directly to customers.
• You need protection against impact and compression.
• The box may be stacked during storage or transit.
• Durability is more important than ultra-high print quality.

Decision Matrix: Matching Thickness to Product Type

Use this quick reference to narrow down your options:

Product Type, Recommended Material, Why

Cosmetics (lipstick, eyeshadow) 16pt – 18pt Paperboard Lightweight, excellent print quality for branding

Skincare (serum bottles) 18pt – 20pt Paperboard or E-Flute Corrugated Balance of luxury feel and protection for glass

Candles 18pt Paperboard or B-Flute Sturdy enough to support weight, good print surface

Baked goods (cookies, pastries) 16pt – 18pt Paperboard or E-Flute Food-grade material, optional window cutouts

Clothing E-Flute or B-Flute Corrugated Lightweight but protective; ideal for shipping

Electronics B-Flute or C-Flute with custom inserts. Maximum protection against drops and compression

Subscription boxes B-Flute Corrugated Consistent sizing, durability for monthly shipments

Luxury gift sets 20pt+ Paperboard or Rigid Box, Premium feel, often combined with custom inserts.

The Cost Consideration

Thicker materials cost more per unit—but that doesn’t always mean higher overall expense. Consider:

• Shipping Savings: A custom-fit box with appropriate thickness often reduces dimensional weight charges, saving you money per shipment.
• Damage Prevention: Investing in the right thickness reduces product returns and replacements.
• Brand Perception: For retail products, a thicker board signals quality and justifies premium pricing.

Common Mistakes to Avoid

1. Using paperboard for heavy items destined for shipping. Paperboard is not designed to withstand stacking or rough handling during transit.
2. Oversizing boxes unnecessarily. Even with the right box thickness, an oversized box increases shipping costs and requires more void fill.
3. Choosing corrugated when high print quality is essential. While E-Flute corrugated prints well, it doesn’t match the crispness of paperboard offset printing.
