Magnetic Closure Round Gift Box with Satin Lining — Cylindrical Premium Packaging

Product Overview

Bincai’s cylindrical magnetic closure gift box stands apart from standard rectangular packaging with its elegant 360°-printable round silhouette. The rigid 2.0mm greyboard tube is precision-rolled to ±0.5mm diameter tolerance with a seamless exterior wrap in 157gsm art paper — full CMYK offset printing covers the entire cylinder in a single continuous image. A precision-fit lid with embedded N42 neodymium magnets (≥8N pull force) provides invisible magnetic closure with a satisfying snap. The interior is lined with your choice of satin, velvet, suede, or electrostatic flocking. Available in 7 standard diameters from 80mm to 250mm with custom heights from 40mm to 300mm. Manufactured on KBA Rapida 105 4-color offset with Heidelberg Speedmaster CD 102 7+1 UV and Bobst SP 102 BMA foil stamping at our 18,000 sqm ISO 9001:2015 & FSC certified facility in Foshan Guangdong. 22 years of rigid box craftsmanship since 2003 — 220,000+ boxes daily output.

Production Quality

Quality Assurance & Testing

Production Workflow

1. Structural Design — 3D CAD modeling of cylinder dimensions, lid fit tolerance, and magnet placement; digital prototyping for client approval before tooling
2. Material Preparation — Greyboard rolls (2.0mm thickness) precision-cut to cylinder circumference and height; 157gsm art paper surface wrap printed and cut; satin/velvet/suede interior fabric pre-cut
3. Offset Printing — KBA Rapida 105 4-color press prints the exterior surface wrap in full CMYK at 16,000 sheets/hour; Heidelberg Speedmaster CD 102 7+1 UV for specialty coatings and metallic effects; continuous-image artwork aligned for seamless 360° wrap
4. Foil Stamping & Specialty Finishing — Bobst SP 102 BMA hot foil stamping for gold/silver/rose gold accents on exterior wrap; embossing/debossing for tactile brand elements; spot UV for gloss-on-matte contrast
5. Tube Rolling — Greyboard precision-rolled into cylinder form on automatic tube-winding machines; ±0.5mm diameter tolerance maintained; adhesive seam positioned for minimum visibility behind surface wrap
6. Surface Wrap Application — Printed surface wrap applied to rolled tube with precise alignment; seam positioned at back or under brand label; registration ±0.5mm for continuous-image artwork
7. Magnet Embedding — N42 neodymium magnets embedded in lid rim and box rim at 3 or 4 equidistant positions; alignment jigs ensure perfect polarity and flush lid seating; pull-force tested per unit
8. Interior Lining — Satin/velvet/suede/flocking applied to interior walls and base with wrinkle-free adhesive technique; optional die-cut foam insert fabricated to product-specific cavities; fabric edge-tucked cleanly
9. Lid Assembly — Rigid lid constructed with same tube-rolling process; lid fit tolerance verified against base tube; magnetic snap tested for reliable closure and seamless appearance
10. Final QC — 100% visual inspection: wrap alignment, foil registration, magnet alignment, interior lining quality, lid fit; drop testing per ISTA 1A; batch color verification per ISO 12647-2; AQL 2.5 sampling per ISO 2859
