Medical Device Packaging Box Customization Case
Project Metrics
【Project Overview】
Industry: Healthcare
Product: Medical devices
Quantity: Small batch initial delivery | Type: Bottom-lock boxes + double-insert boxes + self-sealing boxes (multi-SKU)
Material: 350g white cardboard (laminated)
Process: PANTONE spot color printing + white cardboard lamination + precision die cutting
Delivery time: Batch delivery after sample confirmation
【Client Background】
A medical device manufacturing enterprise needed packaging boxes for its product series. Product specifications varied, with different packaging versions for different models, while having high requirements for packaging protection performance and brand consistency.
💬 Customer Needs
The client's previous packaging had several issues: First, the single-layer cardboard lacked stiffness, making the box prone to deformation during transportation and storage, affecting product image. Second, the brand standard color was a PANTONE spot color, and ordinary four-color printing had significant color variations between batches, making the color difference obvious when packages from different batches were placed together. Third, the product specifications varied, with different sizes for each model, requiring corresponding packaging versions while maintaining a unified visual style.
The client wanted packaging that is rigid and not easily deformed, with pure and bright printing colors, highly consistent brand standard colors, and support for subsequent product series development.
Core demands: Product protection + Precise brand color reproduction + Multi-SKU unified management.
Project challenges:
✓ Initial batch size is small, making traditional plate-making costs prohibitive
✓ Product specifications vary, each model needs different packaging versions
✓ Strict color difference control required between PANTONE spot color batches
✓ Medical devices require high transportation protection, balancing display and compression resistance
💡 Solution
To meet the client's requirements, Lexiang adopted a 350g white cardboard lamination solution, giving the packaging box excellent stiffness and compression resistance. PANTONE spot color printing technology was used, which produces purer and brighter colors compared to four-color overprinting, with precise brand color reproduction and smaller color variations between batches.
Selection analysis:
Why choose 350g white cardboard lamination instead of single-layer cardboard?
Single-layer 350g white cardboard has limited stiffness. When used for bottom-lock boxes or double-insert boxes, the box body is prone to deformation under long-term compression during transportation stacking and storage. After laminating two sheets of 350g white cardboard with eco-friendly glue, the overall stiffness of the cardboard approaches that of 700g cardboard, while surface flatness remains unaffected and printing quality remains fine.
Why not directly choose thicker single-layer cardboard (e.g., 700g white cardboard)?
Single-layer white cardboard above 700g is rare in the market, with long procurement cycles. Increased thickness also makes die cutting and creasing more difficult, which is not suitable for automatically-glued box types like bottom-lock boxes. The lamination solution allows flexible combinations using standard specification raw materials, with controllable delivery times.
Why use PANTONE spot color instead of four-color printing?
Medical device brand standard colors are typically specific color numbers. Four-color printing (CMYK overprinting) can rarely achieve complete consistency between batches, especially when humidity and temperature vary between batches, making color differences more obvious. PANTONE spot color uses pre-mixed ink for direct printing, ensuring consistent color within the same ink batch, and minimizing differences between batches through standard color management processes—making it more suitable for medical products with strict brand color requirements.
Why not use digital printing instead of spot color?
Although digital printing offers flexibility for small batches, its CMYK color gamut is limited, making it impossible to accurately reproduce some PANTONE color numbers. For medical devices with strict brand standard color requirements, PANTONE spot color printing remains the preferred option.
Production implementation and quality control:
① Sample confirmation (PANTONE color number comparison) → ② White cardboard lamination (even eco-friendly glue application + pressure bonding)
③ Laminated cardboard curing (sufficient drying) → ④ PANTONE spot color printing (density testing)
⑤ Precision die cutting → ⑥ Automatic box gluing (bottom-lock/double-insert/self-sealing)
⑦ Inspection (dimensional tolerance ±0.5mm, color density, crease line width) → ⑧ Packaging and shipping
Core quality control: PANTONE spot color printing density and color difference must be within standard ranges, with samples retained from each batch for comparison.
✅ Project Results

✓ Delivered products: Medical device packaging boxes (bottom-lock boxes + double-insert boxes + self-sealing boxes)
✓ Material specifications: 350g white cardboard (laminated)
✓ Printing process: PANTONE spot color printing
✓ Covered models: Multi-SKU unified packaging standard
【Usage Effects】
✓ Packaging is rigid and compression-resistant, box body remains intact during transportation and storage
✓ PANTONE spot color accurately reproduces brand standard colors, color difference between batches within acceptable range
✓ Multi-SKU packaging maintains unified style, reducing client packaging management costs
Case Summary:
Medical device packaging design must balance product protection, brand image, and batch consistency. This case uses 350g white cardboard lamination, achieving box stiffness close to 700g cardboard while maintaining paper surface flatness, effectively meeting transportation compression requirements. Printing uses PANTONE spot color technology, controlling color differences between batches through standard color management processes, ensuring consistent brand colors when packages from different batches are displayed on shelves. Multiple structures (bottom-lock boxes, double-insert boxes, self-sealing boxes) meet differentiated needs of different models within the same product line.
Lexiang Experience:
Applicable scenarios: Medical device packaging, color boxes with strict brand colors, multi-SKU unified packaging
Material recommendations: Choose 350g single-layer white cardboard for standard strength; choose white cardboard lamination (350g+350g) for higher stiffness; choose F-flute corrugated color boxes for lightweight protection
Not applicable scenarios: Not suitable for devices requiring sterilization before packaging (paper boxes are not suitable for EO/steam sterilization, must be sterilized separately before insertion)
Notes: Laminated cardboard must be fully dried before die cutting, otherwise crease precision will be affected; PANTONE spot color printing requires retaining standard color cards for comparison before each production run
Professional Knowledge:
How to choose between white cardboard lamination vs single-layer cardboard vs corrugated cardboard?
Laminated cardboard: Two sheets bonded together, stiffness close to double thickness effect, high surface flatness, suitable for premium color boxes. Disadvantages: Higher cost than single-layer, not suitable for complex structures requiring bending.
Single-layer white cardboard: Best cost-performance, standard 300-400g white cardboard meets most color box needs. But die cutting and creasing difficulty increases beyond 400g.
F-flute corrugated color boxes: Lightweight protection scenarios (products within 1-2kg), low cost, light weight, suitable for e-commerce volume. But surface printing quality is not as fine as white cardboard.
How to choose between PANTONE spot color vs four-color CMYK?
Spot color: Precise brand colors, wide color gamut, small color differences. Suitable for medical, cosmetics and other industries sensitive to brand colors. Each color requires separate plate making, multi-color costs increase with color count.
Four-color: Low cost, can present full-color designs. Suitable for packaging with complex patterns and rich colors. But matching accuracy for specific color numbers (e.g., deep blue, dark red) is limited.
Why choose Lexiang:
✓ Small batch minimum order, no need for large inventory for new product trials
✓ PANTONE spot color printing with high batch consistency, long-term supply color difference controllable
✓ Mature white cardboard lamination technology, balancing stiffness and printing performance
✓ Multi-SKU management with unified box type + differentiated die cutting
✓ Fast sampling speed, confirm effects quickly before batch production
