wholesale holographic scratch cards

When purchasing wholesale holographic scratch cards, you must prioritize security and visual appeal. Key specifications include paper weight (typically 250gsm to 400gsm art paper), the type of holographic film (rainbow, laser, or custom 3D patterns), and the opacity of the scratch-off layer. Ensure the scratch coating is opaque enough to prevent 'candling' (shining light through the card to see the code) but soft enough to be removed easily with a coin without damaging the underlying data.

Security is the most critical factor for scratch cards. You should require the supplier to use automated inkjet numbering systems and provide a data encryption protocol for transferring PIN lists. Ask if they offer black-core paper or silver-bottom coatings to prevent X-ray or high-light penetration. Additionally, verify that the supplier has strict waste management policies to shred misprinted cards containing active codes.

For the US and EU markets, the materials must comply with REACH and RoHS standards, ensuring the inks and scratch-off coatings are non-toxic and lead-free. If the cards are intended for children's promotions, they must meet EN71-3 or CPSIA requirements. Always request SGS or Intertek test reports for the chemical composition of the scratch-off latex.

Suppliers on Made-in-China.com typically offer extensive customization, including custom holographic overlays with your brand logo, unique shapes via die-cutting, and multi-color offset printing. For high-end applications, you can request UV spotting, gold foil stamping, or QR code integration that links to a digital verification landing page.

The most common risk is a 'hard scratch' where the coating won't come off, or a 'pre-scratched' surface due to poor packing. To mitigate this, request a pre-production sample to test the scratch sensitivity. Use Trade Fullfillment services on Made-in-China.com and mandate a third-party pre-shipment inspection (PSI) to check at least 100 random cards for scratch-off quality and code readability.

Focus on volume-based pricing tiers; for scratch cards, the setup cost for holographic plates is high, so unit prices drop significantly after 10,000 units. Negotiate for free plate-making on repeat orders and ask for overrun allowances (usually 1-3% extra cards) to cover any potential shipping damage.

Since scratch cards are relatively heavy but compact, Sea Freight (LCL) is most economical for large wholesale volumes. However, because these are often time-sensitive for marketing campaigns, Air Freight or Express (DHL/FedEx) is preferred for smaller batches. Ensure the supplier uses moisture-proof shrink-wrapping and heavy-duty corrugated cartons to prevent humidity from affecting the scratch-off latex during transit.

Never pay the full amount upfront for custom prints. Follow the 30/70 payment rule: a 30% deposit to start production and the 70% balance paid only after you receive a quality inspection report and the Bill of Lading (B/L).
