Case Studies Successful Custom Packaging Projects — Kuzo Packing

Case Study 1: European Badminton Brand — 42mm Offset Tubes

Client: Mid-tier European badminton brand
Challenge: Existing packaging — a white plastic tube with a sticker label — wasn't differentiating the product in a market where shuttlecocks are sold at court-side pro shops with minimal staff assistance
Solution: Custom 42mm × 340mm paper tube, 4-color offset printing, gloss laminate, custom PE cap in brand color
Order: 15,000 units
Unit cost: $0.32
Result: The brand reported that distributors specifically cited improved shelf visibility. The custom tube was distinguishable from competitors at a glance, reducing the reliance on staff recommendations. Their reorder volume increased from 15,000 to 25,000 units within 8 months.

Case Study 2: US Protein Snack Brand — Amazon FBA Ready

Client: US-based functional snack brand selling protein crisps
Challenge: Flexible pouch packaging resulted in a 12% product damage rate through Amazon FBA (crushed product, opened pouches). Customer reviews reflected packaging dissatisfaction.
Solution: Custom 73mm composite paper can, aluminum foil inner liner (MVTR <2), push-up bottom mechanism, full-bleed offset print with matte laminate
Order: 8,000 units (initial)
Unit cost: $0.41
Result: Product damage rate dropped to under 2%. Amazon review average improved from 4.1 to 4.4 stars. Repeat purchase rate increased 17% within 90 days. The brand now orders 30,000 units per production run.

Case Study 3: Southeast Asian Tea Brand — Premium Gift Format

Client: Specialty loose-leaf tea brand targeting high-end retail
Challenge: Existing rectangular box packaging felt generic for a product retailing at $22. Brand wanted packaging that justified the premium price point.
Solution: Custom 55mm × 180mm Kraft paper tube, offset-printed nature artwork, wood-effect cap with silicone seal, embossed brand logo, gold hot-stamped rim
Order: 5,000 units
Unit cost: $0.58
Result: The brand's retail partners reported that the tube packaging was "the primary reason consumers picked the product up." Average retail sell-through time decreased from 8 weeks to 3 weeks. The brand now orders 12,000 units quarterly.

Case Study 4: European Cosmetics Brand — Plastic-Free Transition

Client: Natural cosmetics brand transitioning from plastic to paper packaging
Challenge: Deodorant stick packaging — previously a plastic push-up tube — needed a paper-based replacement that maintained functionality while meeting the brand's "100% plastic-free by 2026" commitment
Solution: Custom 35mm × 100mm spiral-wound paper tube, internal paper push-up disc, water-dispersible barrier coating, oil-resistant inner liner
Order: 20,000 units
Unit cost: $0.22
Result: The switch eliminated approximately 1.2 metric tons of plastic per production run. Consumer feedback was positive, with the paper tube described as "feeling more premium than the plastic version." The brand has since expanded their paper tube packaging to two additional product SKUs.

What These Cases Have in Common

Each project moved from inquiry to production in 25–40 days. Each involved the same core process: spec review → sample approval → production → QC → shipping. The variables that determined success were: clear specifications in the initial RFQ, realistic timelines, and a supplier with documented QC processes.
