How to Make a Rigid Box

Rigid boxes are the gold standard of high-end packaging, combining durability, elegance and a luxurious unboxing experience. Whether it's high-end retail, cosmetics, electronics or gift packaging, rigid boxes provide a sturdy structure and enhance brand recognition.

I.What is a rigid box?

Rigid boxes (also called combination boxes) are a high-end packaging solution made of thick, non-folding material. Unlike folding cartons, rigid boxes retain their shape even when empty, making them ideal for luxury goods.

Common uses:

Luxury retail packaging (watches, jewelry, perfumes)

Electronics (smartphones, headphones)

Cosmetics (high-end skincare, makeup)

Gift boxes (wedding gifts, corporate gifts)

II.Materials needed to make a rigid box

To make a high-quality rigid box, you need:

1. Paperboard (or grey board) - the core material (usually 1 mm to 3 mm thick).

2. Covering material - high-quality paper, leather, fabric or textured laminate.

3. Adhesive - a high-strength glue to bond the layers together.

4. Lining material (optional) - velvet, satin or foam for interior filling.

5. Decorative elements - embossing, hot stamping or magnetic clasp.

III.Rigid box manufacturing process (manual and automated methods)
 

Step 1: Material preparation

Boardboard cutting: Cut the base and cover to exact size (manual die cutting or automated CNC cutting).
Cover material preparation: Prepare printed/white paper, leather or fabric for packaging.

Step 2: Packaging and gluing

Manual: Apply adhesive to the board, wrap the cover, and trim the excess.
Automated: The machine is precisely controlled by PLC to feed, glue and pack the materials automatically.

Step 3: Corner reinforcement

Edges: Fold and press the corners; use edge tape for durability.
Automated: Hydraulic system completes forming and uniform gluing in one step.

Step 4: Bottom/cover assembly

Installation: Align and press the bottom/cover to make it close tightly (manual inspection or automatic positioning).
Quality Check: Ensures consistent size, finish and construction.

Step 5: Output and Packaging

Manual: Finished cartons are stacked and packed.
Automated: Conveyor system sorts and outputs cartons at high speeds (e.g., 1,000+ per day).

Rigid box production includes cutting cardboard into base/lid shapes, wrapping with paper/leather, reinforcing corners and assembling components – a process that can be fully automated for efficient, high-quality output.
