Custom Magnetic Closure Boxes: The Ultimate Global Procurement & Engineering Blueprint

We predominantly specify rare-earth **N35 to N52 Grade Neodymium (NdFeB) disc or block magnets** embedded directly into the chipboard core. For standard book-style gift boxes, N35 disc magnets (10mm diameter x 1.5mm thickness) provide an optimal pull force of approx. 0.8 kg. For larger collapsible flat-pack boxes or heavy-duty packaging, we use dual pairs of N52 magnets (12mm x 2mm) delivering over 1.2 kg pull force to guarantee the lid remains firmly closed during handling and transport without accidental popping.

Standard pre-assembled rigid boxes carry high volumetric weight (shipping empty air). **Collapsible magnetic boxes** feature precision V-groove fold lines and four corner adhesive flaps or magnetic locks, allowing the box to collapse entirely flat. This reduces cubic meter (CBM) volume by **up to 75%**. A order of 5,000 pre-assembled rigid boxes that would normally require two 40-foot ocean containers can fit onto less than one container when shipped flat-pack, yielding massive savings on logistics, customs clearance, and warehouse storage fees.

Standard rigid boxes contain mixed materials (paperboard, glue, wrapping paper, metal magnets). At Teal Packaging, we manufacture **eco-friendly recyclable builds** featuring FSC-certified recycled paperboard and water-based inks. Upon request, we incorporate concealed tear-tabs or micro-perforated interior magnet pockets. This structural feature allows the end user to easily peel back the paper tab and extract the neodymium magnets for metal recycling prior to placing the paperboard box directly into standard municipal paper recycling streams.

Our factory minimum order quantity for custom printed magnetic closure boxes starts at **100 units**. Volume pricing breaks apply at 300, 500, 1,000, 3,000, and 5,000+ units. Because setup costs (cutting dies, print plates, CNC foam programming) are amortized over the total run size, unit pricing drops significantly as order volumes increase.

Yes. A premium exterior box must be paired with precision internal cushioning. We design and manufacture custom inserts including:
• **High-Density EVA / PE Foam:** Velvet-flocked or plain finish, CNC-milled to exact bottle or item contours.
• **FSC Molded Paper Pulp:** Eco-friendly 100% paper alternative engineered for heavy products.
• **Folded Cardboard Cradles:** 18pt–24pt SBS paperboard die-cut with locking tabs for clean presentation.
All custom inserts are tested to ensure compliance with ISTA 3A drop safety standards.

Pre-production structural CAD dielines are completed within **24 hours**. Plain or digitally printed structural samples take **3 to 5 business days**. Mass production generally requires **10 to 14 business days** following digital proof and sample approval. Expedited rush production (4 to 7 days) is available upon request for qualified art files. Sea transit to North America/Europe averages 20–30 days, while air express delivery takes 4–7 days.

Magnet failure occurs in cheap manufacturing when magnets are manually glued on top of paper after assembly. Teal Packaging uses **automated CNC die-slotting machinery** to route precise recesses directly into the grayboard panel before paper wrapping. Magnets are placed using robotic feeders equipped with polarity-checking sensors. This ensures:
1. Magnets are 100% invisible beneath the paper wrapper (zero surface bulging).
2. Zero polarity reversal (magnets attract perfectly every time).
3. Lids sit 100% flush without offset or crooked edges.
