ASTM Certified & Fully Customizable Child-Resistant Tin Packaging
CR Tin (Andylots Tin Box Packaging Co., Ltd) operates as a streamlined, single-source global provider of advanced child-resistant (CR) tin packaging systems. We unify design, structural mold fabrication, strict protocol compliance verification, and high-volume industrial manufacturing under a single roof. Our focus is to deliver highly secure, eco-friendly metal packaging that complies with strict global regulatory protocols while maximizing commercial presence on the shelf.
Founded on a vision of supply chain reliability, CR Tin pioneered child-resistant tin development back in 2017. Backed by nearly a decade of focused R&D, our portfolio boasts over 70 certified child-resistant tin structures. Our engineering capabilities cover all shapes and form factors required by the industry, allowing us to build an integrated system that protects children, honors consumer aesthetics, and guarantees rapid supply chain velocity.

The global metal packaging market is witnessing unprecedented transformation. Driven by the worldwide push to eliminate single-use plastics, consumer packaged goods (CPG) companies are realigning their procurement strategies toward tinplate and aluminum. High-end confectionery, premium tea, specialty wellness products, and regulated pharmaceuticals are increasingly utilizing premium metal boxes. Tins offer unmatched light, gas, and moisture barrier properties, significantly extending the shelf-life of delicate formulations such as nutraceutical gummies, mints, and active-ingredient cartridges.
Furthermore, in highly regulated industries—such as legal adult-use cannabis in North America and medical hemp in Europe—packaging must fulfill rigid dual functions. It must present high-end branding opportunities and assure safety through robust child-resistant mechanisms. Our factories produce high-durability tins that eliminate VOC emissions, remain infinitely recyclable, and elevate standard product presentations into premium lifestyle statements.
Operating in China gives CR Tin immediate access to the world's most mature tinplate supply ecosystem. The resilience of our supply chain is built on vertical integration—from domestic raw steel purification to highly specialized local lithographic printer operations. This minimizes risk against global container shipping volatility, material shortages, and energy fluctuations.
Efficiency is driven by the application of smart factory automation. At CR Tin, we operate more than 8 specialized automated production lines. Our robotic pick-and-place systems, continuous automated stamping presses, and online camera inspection systems ensure that tolerances are kept within fractions of a millimeter. By reducing dependency on manual labor, we guarantee consistent production rates, lower cost-per-unit metrics, and eliminate functional variance across high-volume production batches.
"Through integration with local accessory partners (food-grade silicone liners, certified custom plastic caps, and specialty paper inserts), we cut product lead times down to a standard 30-day timeline—from CAD design validation to container loading."
Packaging is no longer a static physical container; it is now interactive, smart, and fully integrated into the circular economy. The technology roadmap for CR Tin centers on three core pillars: material science, mechanical optimization, and smart branding.
| Technology Pillar | Current Engineering Status | Next-Gen Integration (2025-2028) |
|---|---|---|
| Material Optimization | 0.23mm electrolytic tinplate (ETP), post-consumer recycled steel. | Ultra-thin high-tensile steels, bio-based internal coatings (BPA-free & PFAS-free). |
| Locking Mechanisms | Double-button hinges, slide-and-press, and screw-lock caps. | Hybrid bio-plastic & tin closures, child-resistant yet elder-friendly ergonomic curves. |
| Airtight Performance | Silicone/rubbery gaskets and friction-fit plastic rings. | Integrated biodegradable elastomer seals with built-in desiccant compartments. |
| Branding & Security | 4-color CMYK lithography, spot UV, and structural embossing. | Laser-etched serial numbers for anti-counterfeiting and RFID-enabled smart tracking. |
Consumer preferences and packaging regulations vary greatly by region. Our design process starts with a careful study of regional consumer behavior and local compliance requirements:
Compliance is a core design requirement, not an afterthought. At CR Tin, every child-resistant design goes through extensive testing to meet US Consumer Product Safety Commission (CPSC) and ISO standards. We carry out ASTM D3475 child-resistant testing using third-party laboratories. This testing ensures that our packaging is difficult for children under 5 to open, while remaining easy to use for adults and seniors.
We also provide comprehensive documentation for customs and regulatory audits, including food-contact certifications (FDA & EU food-grade), material safety data sheets (MSDS), and compliance certificates. Our logistics team handles shipping details, including customs clearance and direct delivery to customer warehouses in Europe and North America.
How CR Tin combines technology, quality control, and manufacturing scale to support your brand's growth.
Decades of combined engineering experience in child-resistant mechanism design. We create tins that balance secure locks with premium aesthetics.
Choose from more than 12 pre-certified child-resistant locking mechanisms, helping you get your products to market quickly and safely.
Equipped with 8+ automated production lines to increase speed, lower unit costs, and maintain precise quality control at scale.
Every batch undergoes three levels of quality checks (IQ/OQ/PQ), ensuring child-safe lock function and precise lid-to-base fit.
Combining customized product development with advanced manufacturing processes.
We offer over 12 distinct child-resistant tin structures to match your brand's unique style. We provide 3D rendering and physical 3D-printed plastic samples during development to help you fine-tune the look and feel before mass production begins.
Our packaging engineering team has decades of design experience. We develop custom tin shapes, integrated airtight seals, and special finishes (embossing, custom inks) to make your brand stand out on retail shelves.
We test every production run to ensure child-resistant lock function and airtight performance. Advanced automated lines keep quality consistent, while manual inspectors review final product assembly.
From premium airtight tins to recycled material choices, we cover your product's safety needs. Our custom packaging options help you protect your brand while staying compliant with local regulations.
