How Thick Should a Rigid Box Be? A Complete Packaging Guide

In modern era, packaging is considered more than just a box. It shows value, protection, and brand identity. When it comes to luxury products, custom rigid boxes are one of the most preferred and ideal options. In a crowded market where first impression holds a significant importance, a premium rigid box helps brands stand out. This type of packaging option is being used by all businesses and brands, from cosmetics to high-end goods, to attract buyers.

What Are Rigid Boxes?

A rigid box is a luxurious form of custom packaging solution typically manufactured from thick, durable paperboard. Unlike other ordinary folding cartons, these custom rigid boxes are already pre-assembled and retain their unique shape for a longer time. It creates a high-end and premium feel to the items packed in it. 

The main purpose of these boxes is to provide 100% protection to the products from damage during shipping or handling. Perfectly designed boxes will make your business distinct from other competitors in the market. You can craft them in any color, shape, custom size, or style. 

Why Thickness Is An Important Factor?

When you choose a packaging box, the thickness is a great element that truly reflects flexibility, durability, functionality, and unique aesthetics. The ideal thickness of a box is not a universal standard, but it really varies based on the product, size, & its purpose. 

Moreover, the thickness ranges for the chipboard core are 1.5 mm to 3 mm (60pt to 120pt). For heavy items, the rigid box board thickness can go as high as 4 mm.

The thicker the material, the rigid the box, ensuring your premium gifts withstand transportation without compromising their quality, protection, and luxury appeal. 

Standard Thickness Options for Rigid Boxes

The right thickness depends on the product's needs, the desire for a premium feel, and durable protection. There are some common thicknesses used to create rigid packaging boxes. The standard rigid box thickness ranges from 1.5mm to 3mm (approximately 36pt to 120 pt). You can also go up to 4mm for more fragile and larger products. 

Thickness Guidelines

1.5mm – 2mm

Cosmetic items, perfume, watches, bottles, candles, electronics products, and other small jewelry items require a 1.5mm-2mm thickness level. This luxury packaging board thickness provides a good balance of sturdiness and sophistication without being overly bulky.

Your premium or fragile items, like candles, will not break in rigid candle boxes made with heavy-thickness boards. 

2mm – 2.5mm

It’s a common choice for a vast range of products, including high-end apparel, electronics like tablets or phones, shoes, and other gift sets. This provides great protection and a luxury feel.

2.5mm – 3mm

This thickness level is considered best for heavy-duty and delicate items. Examples like tech gadgets,  fragile wine bottles, luxurious perfumes, and premium watches, where durability is needed.

Factors Affecting The Choice Of Thickness

The ideal thickness is mostly determined by balancing some key elements, including the company’s budget, business image, features & characteristics, and other logistical needs. 

Some factors include;

Product Weight & Fragility

The primary consideration for rigid packaging box thickness is their product’s weight and fragility. Heavy or delicate products demand thicker boards to prevent crushing or damage during handling or transit. Items like electronics or fragile glassware need a sturdier box (3-4mm). If we compare to lightweight products, lime cosmetics or jewelry, a thin board (1.5-2mm) is perfect to balance durability and elegance without extra cost. 

Luxury Appeal

A thicker board offers high-end and luxury appeal to the rigid boxes. Thick and durable rigid packaging boxes allow for a memorable unboxing experience, which truly helps build brand loyalty. It also supports high-end printing methods and finishes like vivid foil stamping and embossing more efficiently. Grab this option for a luxury feel!

Cost 

Thicker, rigid packaging boxes are expensive due to the material costs for the thicker paperboard, but they provide a great brand value. Brands should balance the needed luxury appeal and protection within their budget. The additional weight of a thicker packaging box can increase overall shipping costs, especially for international freight. So, investing in this rigid box can reduce damaged goods and returns.

Storage & Shipping

For items that will be stacked in storage, a thicker, rigid packaging box is necessary to withstand weight and prevent damage. Edge boards are commonly use to boost stacking strength.

Material Used in Rigid Boxes

Some sturdy materials are used in the making of rigid boxes. It includes a thick inner core and an aesthetic outer wrap. Remember that quality is not only determined by thickness; the core's density is also a main factor. 

Core Material: Chipboard/Greyboard

The core structure of rigid packaging boxes is dense paperboard, typically known as chipboard or greyboard. This packaging material is mainly manufactured from compressed layers of biodegradable paper pulp and wood chips, which offer its ideal strength. Unlike the hollow fluting of corrugated packaging, chipboard is a durable and dense material. 

Its thickness commonly ranges from 1.5mm to 3mm, which is way thicker than other standard folding cartons. Different high-end grades of greyboard or chipboard are commonly used. 

Outer Wrap Materials

The outer wrap of the packaging box is much thinner and is glued around the chipboard core. This feature is what provides the box’s aesthetic branding. Wraps for a custom box can be made using a variety of DIY materials. Such as;

• Printed paper: Standard paper can print with top-notch quality logos, eye-catching graphics, and other unique branding elements. 

• Specialty paper: Options for specialty paper are linen and leatherette, metallic papers to add a memorable tactile experience.

• Fabric and leatherette: For the premium & luxurious packaging look, fabric or leather is used to wrap the core, enhancing the perceived value and overall unboxing experience.

Design & Structural Impact

The unique design and structural impact of the custom boxes hold great significance.  The thickness of the rigid boxes’ chipboard core is a main element of its overall design and structural integrity. Thicker boards have sharper edges that hold their unique shape perfectly and allow for more right edges and corners. Moreover, a thicker core is a durable and sturdier packaging box. It prevents the box from crushing or bending during shipping or display.

Effect On Specific Box Styles

The effect of board thickness varies with different styles, which include the following design ideas for rigid packaging:

1. Magnetic Closure Boxes

These magnetic closure boxes use durable embedded magnets to make a snap-shut closure. A thicker greyboard is important for holding the magnets professionally and securely within the box structure. Moreover, the thinner boards can result in magnets that are seen as large bumps or fail to align with the box, compromising both the appeal and functionality.

2. Drawer Boxes

Rigid drawer boxes style features an inner tray that simply slides out from a sleeve. A thicker board ensures a smooth and satisfying sliding motion. It can flex under pressure, causing the packaging box drawer to stick.

3. Two-Piece Boxes

Two-piece consist of a separate lid and base; they rely on a snug fit to maintain their overall elegance. If you use a thicker board, it guarantees that both pieces of the two piece rigid boxes hold their shape professionally and elegantly.

By this method, the lid slides on and off smoothly.

Printing & Finishing

Do you know what is the key to luxury branding? It’s printing and finishing on rigid boxes. Thicker materials serve as a unique canvas for premium finishing and printing techniques.

The following options are;

• Embossing And Debossing

These methods involve creating recessed designs (debossed) or raised (embossed) designs. A thicker chipboard offers the greatest strength, resulting in a well-defined box without damage.

• Foil Stamping

This finishing process involved applying a thin layer of colored foil to the surface using heat & pressure. On a thick box surface, the foil has a more luxurious look with a defined edge.

• Dimensional Coatings

Coating methods like Spot UV rely on the packaging box surface to create a glossy effect. These coating options will look good on the thicker materials.
