Empty capsule blister pack

Selecting the correct material is critical for product stability. For standard moisture protection, PVC (Polyvinyl Chloride) is the most common and cost-effective choice. If your capsules are highly sensitive to humidity, you should opt for PVDC-coated PVC or Alu-Alu (Cold Form Foil), which provides a 100% barrier against moisture, light, and oxygen. Ensure the lidding foil is Hard Tempered Aluminum (20-25 microns) with a heat-seal lacquer compatible with your base web material.

As these packs directly contact health products, they must meet stringent safety standards. Ensure the supplier provides FDA (Food and Drug Administration) compliance or DMF (Drug Master File) registration. Materials must be BPA-free and comply with USP <661> or EP 3.1.11 standards for plastic packaging. Always request a COA (Certificate of Analysis) for every batch to verify the absence of heavy metals and phthalates.

To avoid production downtime, verify the roll width, core diameter (usually 76mm), and outer diameter of the material rolls. For pre-formed blister sheets, confirm the cavity size (e.g., Size 00, 0, or 1 capsules) and the layout (e.g., 10-count or 12-count) matches your secondary packaging (boxes). Request a technical drawing to confirm the 'draw depth' is sufficient to prevent capsule crushing during the sealing process.

Consider the push-through force of the aluminum foil; it must be fragile enough for easy extraction but strong enough to prevent accidental breakage. For regulated markets, you may need Child-Resistant (CR) lidding foils, which require a 'peel-push' or 'peel-open' mechanism. Additionally, ensure the perforation lines are clean to allow users to tear off individual doses without compromising the seal of adjacent cavities.

The biggest risk is contamination and physical deformation. Ensure the supplier uses double-layer PE bag inner packaging and heavy-duty corrugated cartons with palletization to prevent crushing during sea freight. On Made-in-China.com, prioritize Audited Suppliers who have undergone third-party onsite inspections of their Clean Room (Class 100,000) production environments.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for free cylinder/mold sets if the order exceeds a certain volume (e.g., 50,000 sheets). Ask for a tiered pricing structure where the price drops by 10-15% as you move from 100kg to 1,000kg of material. Always clarify if the price includes custom printing (gravure or flexo) and UV coating.

Use Secure Payment services provided by platforms like Made-in-China.com to ensure funds are only released after you confirm receipt of goods. For large-scale pharmaceutical contracts, insist on a Pre-shipment Inspection (PSI) by a third party like SGS or Intertek to verify seal integrity (Leak Test) and printing accuracy before the balance payment is made.

Due to the high volume-to-weight ratio, Sea Freight (LCL or FCL) is the most economical for bulk orders. However, because PVC can warp under extreme heat, request stowage below the waterline or use reefer containers if shipping through tropical zones. For urgent samples or small trial batches, Air Express is viable, but ensure the packaging is rigid enough to withstand high-pressure changes in the cargo hold.
