Macro Industry Packaging Solutions

Tailoring small metal packaging formats to meet the technical, regulatory, and practical needs of specific commercial industries.

Cannabis & Pre-Roll Formats

Strict ASTM D3475 child-resistant parameters require robust engineering. Our airtight tin cases feature multi-step button systems and silicone gaskets, ensuring prolonged terpene preservation, freshness retention, and full child-resistant regulatory compliance.

Confectionery & Mints

Pocket-sized slide tins and micro hinge systems are perfect for mints, chocolates, and premium lozenges. Incorporating food-grade coatings, clean varnishes, and custom embossing to create highly tactile, collectible retail assets.

Pharmaceuticals & Wellness

Our small tin designs provide excellent barriers against UV radiation, oxygen ingress, and moisture. They are perfect for clinical-grade nutraceuticals, customized botanical gummies, and single-dose therapeutic products.

Technical Roadmap & Manufacturing Engineering

Behind every small tin case lies a sophisticated industrial workflow focused on durability, sustainability, and precision dimensional tolerances.

Advanced R&D Team & Rapid Prototyping

Our dedicated technical engineering department offers complimentary, unique CR tin structure design services. Using state-of-the-art 3D CAD modeling software, we can quickly generate photorealistic 3D renderings and output high-precision SLA plastic prototypes. This allows physical validation of lock functions before investing in tooling.

  • Optimized Structural Ribs: Strategically designed metal deformations that increase case strength without adding weight.
  • Dual-Locking Springs: Dynamic steel tension inserts designed for high repetitive cycling without losing retention.
  • True Hermetic Sealing: Integration of food-grade, FDA-compliant silicone inserts for zero-airflow environments.

Frequently Asked Questions

Answers to key technical, compliance, and ordering questions from B2B buyers.

Q: How do you verify your tin packaging complies with child-resistant standards?
A: Our child-resistant tin styles are engineered and tested in accordance with US CPSC regulations and ASTM D3475 standards. We work with independent, third-party testing laboratories to evaluate and certify child-resistant designs, giving our clients confidence in meeting retail compliance requirements.
Q: What is the typical lead time for a new custom mold?
A: We can build custom molds, create prototypes, and complete pre-production runs in about 30 days. This speed is supported by our integrated CAD tooling studio, in-house CNC equipment, and experienced R&D team.
Q: Can you achieve airtight seals on small tin cases?
A: Yes. We can integrate food-safe silicone gaskets or soft rubber rings inside the lid. This creates an airtight seal that helps preserve product freshness, limits odor release, and protects contents from humidity.
Q: Are the coatings and varnishes safe for food products?
A: Absolutely. All interior coatings, varnishes, and exterior printing inks comply with FDA and EFSA food-contact standards. We regularly test for chemical residues to ensure the packaging is safe for mints, chocolates, and other edibles.
Q: What options are available to prevent the metal from rusting?
A: We apply protective lacquers (such as gold, clear, or white coatings) to the inner surfaces of the tinplate. This prevents rusting and protects the metal from reacting with product ingredients.
Q: What is the minimum order quantity (MOQ) for custom-printed small tins?
A: Our standard production MOQ is 10,000 units. This volume allows us to optimize print setups, configure automated tooling, and keep unit costs competitive.
