In the highly regulated global landscape of vape systems, concentrates, and pharmaceuticals, packaging is not just a container—it is a critical compliance barrier, a brand statement, and an environmental milestone.
CR Tin (Andylots Tin Box Packaging Co.,Ltd) is a streamlined, single-source professional developer and manufacturer of child-resistant (CR) tin boxes. We integrate complete child-resistant lock design, precision mold making, custom prototyping, ASTM-standard testing, and high-volume mass production.
Established in 2017, CR Tin dedicated its engineering capabilities to pioneering child-resistant mechanisms for metal containers. Over nearly a decade of research, development, and industrial scaling, we have secured over 70 certified child-resistant lock tin boxes. Our designs span across all major packaging styles in the industry, allowing us to establish a proprietary, state-of-the-art child-resistant metal packaging system.
Corporate supply chains face dual pressures: shifting away from single-use plastics to satisfy ESG mandates, and complying with stringent child-safety regulations across North America, the European Union, and Oceania.
Global ESG mandates and consumer preferences have placed rigid plastics under intense scrutiny. Tinplate (electrolytic tinplate) is 100% infinitely recyclable, making it the premier choice for premium cartridge packaging. Our food-grade raw materials provide an inert environment that prevents chemical migration, maintaining product purity and terpene profiles.
Regulatory bodies (such as the CPSC in the United States and Health Canada) require child-resistant packaging to pass strict performance tests under 16 CFR Title 1700.20 and ISO 8317 standards. Our certified solutions prevent child access while remaining senior-friendly, allowing compliance teams to bypass the risk of costly import hold-ups.
Enterprise procurement demands more than just custom shapes; it requires structural consistency, batch-to-batch repeatability, and robust safety margins. By automating our lines, CR Tin minimizes variance in lock-mechanism tolerances down to +/- 0.05mm, ensuring seamless performance on automated filling and secondary packaging lines worldwide.
Leveraging advanced metal stamping, automated tool design, and patented mechanical locks to deliver high-performance packaging.
Using state-of-the-art CAD modeling, 3D printing, and plastic rapid prototyping, we visualize and refine custom latch systems within days. We provide rapid physical models to verify lock tension and tolerance before beginning metal tool production.
For vape cartridges, maintaining freshness is key. Our advanced airtight structures utilize FDA-compliant food-grade silicone gaskets and structural locks to prevent aroma leakage and preserve internal humidity levels.
Every single child-resistant structure is optimized to meet US ASTM D3475 standards. We partner with leading testing agencies to ensure that our locks remain simple for adults to open while preventing access by children under 5.
Delivering cost-effective packaging solutions through structural design innovation, manufacturing automation, and vertical integration.
We design simplified child-resistant structures that reduce tool wear and minimize metal waste, saving raw material costs during high-volume production runs.
Our facility features 8+ automated production lines. Automating key stages like structural forming, hinge rolling, and gasket placement increases output speed, improves quality, and lowers labor costs.
We source accessory parts (like plastic buttons and silicone gaskets) from certified long-term partners, ensuring consistent fitment, material compliance, and stable pricing.
