Explore our leading custom-engineered metal boxes designed specifically for sensitive edibles, mints, chocolates, and pre-rolls with advanced protective barriers.
In the rapidly changing consumer packaged goods (CPG) landscape, metal packaging has transitioned from a traditional containment choice into a critical component of brand equity, food safety, and environmental stewardship. Particularly within the premium confectionary, functional mint, luxury chocolate, and cannabis-infused edible sectors, B2B procurement professionals are navigating a complex intersection of regulatory demands, child-safety requirements, and aesthetic positioning.
Historically, packaging for mints and edible products focused primarily on freshness and shelf-life. However, with the emergence of high-potency active ingredients, medicinal applications, and the global legalization of cannabis-infused edibles, the structural integrity of the packaging has taken center stage. Government regulators globally require strict child-proofing (such as the United States Consumer Product Safety Commission’s ASTM D3475 standards and Europe's ISO 8317 certification) to prevent accidental ingestion by minors.
As a result, leading global brands are actively seeking specialized OEM Edible Metal Box Factories capable of providing high-barrier, sustainable, and child-resistant tin packaging. Metal (tinplate) offers a key strategic advantage over plastics: it is 100% infinitely recyclable without loss of material quality, aligning perfectly with corporate ESG (Environmental, Social, and Governance) targets and satisfying conscious consumers' demands for a plastic-free circular economy.
CR Tin (Andylots Tin Box Packaging Co.,Ltd) is a streamlined, single-source professional supplier of child resistant tin boxes, integrating child resistant lock design, mold making and sampling, child resistant lock testing, and mass production.
CR Tin began developing child resistant lock tin boxes in 2017. After nine years of research and development and pioneering experience, we have over 70 certified child resistant lock tin boxes, covering all tin box packaging styles in the industry, and have established our own unique child resistant lock tin box system.
By consolidating our production assets in China's manufacturing heartlands, we bridge the gap between heavy automation, complex structural engineering, and economic efficiency. Our dedicated engineering and research division provides complimentary design services, structural 3D rendering, and fast 3D plastic sample prototyping to ensure your packaging stands out on shelf while complying with all necessary legal frameworks.
B2B procurement of food-grade and active ingredient tinplate packaging involves complex safety parameters. Enterprise buyers must prioritize the following dimensions to mitigate supply chain risks and compliance failures.
Packaging must feature a verified two-step opening mechanism that is intuitive for adults (including seniors) but impenetrable for children under 5 years old. Securing certifications reduces legal liability and product recall risks.
For edible products like mints, functional gummies, or cannabinoid-infused chocolates, oxygen and humidity degrade active components and essential oils. Tins must utilize food-grade silicone gaskets or air-tight inner linings to maximize shelf-life.
All coatings, paints, and rust-resistant coatings applied to the tinplate must be FDA-compliant, Bisphenol A (BPA)-free, and comply with EU food contact standards. Quality assurance must verify raw materials through SGS or Intertek reporting.
OEM factories must have robust industrial capacities. Utilizing automatic stamping, embossing, and assembly lines protects against human error, stabilizes unit cost structure, and supports major Q4 holiday product rollouts.
Custom tin designs are highly tactile. Brands require multi-level embossing, textured finishes (matte, gloss, metallic, sand oil), and custom dimensions tailored to pocket portability or gift-box displays.
Unlike thin plastics, thick food-grade tinplate protects structural shape during logistics, preventing fragile product crushing and maintaining premium presentation when it reaches retail shelves.
By controlling the entire lifecycle from early-stage industrial design to high-volume automated production, we deliver unparalleled value to our global clients.
CR Tin has designed and manufactured a comprehensive portfolio of certified child-resistant metal packaging solutions. Over 12 distinctive certified mechanisms exist for immediate choice—including button-locked slide boxes, push-tab lids, and turn-and-push canisters.
These pre-certified molds allow brands to skip the costly, time-consuming process of independent child-resistant testing, which can cost thousands of dollars and take months. Instead, they can apply their custom branding and graphics directly to a proven, tested blueprint.
Every product starts with custom design. Our engineering team converts conceptual ideas into detailed CAD structures, optimizing details like metal-on-metal friction and snap fitments.
To speed up the validation phase, we offer free unique CR tin design and creative services, including photorealistic 3D rendering and functional 3D plastic samples. This allows clients to test physical ergonomics and compliance mechanisms before committing to custom tooling.
High-volume supply demands consistency. Variation in tin thickness or locking mechanism alignment can cause compliance failures, making tins either too loose or impossible to open.
We deploy advanced automatic stamping lines, sensor-guided quality control cameras, and multi-stage manual inspections. By maintaining tight tolerances throughout the blanking, drawing, bending, and assembly processes, we ensure that every box delivered operates flawlessly.

How CR Tin tailors designs to meet different global regulatory requirements and application scenarios.
In North America, child-resistant packaging regulations are strictly enforced by the CPSC and Health Canada. For cannabis-infused edibles, gummies, and tablets, the packaging must be certified under the ASTM D3475 standard. This requires testing with children aged 42-51 months (who must not be able to open the package) and seniors aged 50-70 years (who must be able to open and re-close it successfully). Additionally, packaging in Canada must be opaque and child-resistant. Our custom metal tins are designed to meet these regulations, providing high barrier protection without needing thick, non-recyclable plastic liners.
European B2B procurement is heavily influenced by the Packaging and Packaging Waste Regulation (PPWR), plastic taxes, and Extended Producer Responsibility (EPR) programs. For European mint, chocolate, and medicinal lozenge brands, choosing tinplate is a strategic decision to avoid plastic taxes. Our tins are designed to meet the EN 14375 standard for reclosable child-resistant packaging. They are 100% recyclable within existing municipal steel sorting lines, helping brands reduce their carbon footprint.
In the APAC region, particularly in Japan, South Korea, and Singapore, the focus is on premium aesthetics and preservation. High humidity requires airtight seals to prevent moisture absorption in products like premium mints and botanical extracts. Our hermetically-sealed tins feature custom press-fit lids and food-grade gaskets to keep products dry and fresh in humid climates.

To achieve certification, a packaging structure undergoes a physical testing panel with a specified cohort of children and adults. By using CR Tin's pre-certified designs, you can bypass this step and significantly reduce your time-to-market. If you choose a fully custom structure, we will manage the design optimization, tool-up, and third-party testing panels on your behalf.
We source our tinplate exclusively from top steel suppliers. All internal varnishes and coatings are certified food-safe, BPA-free, and FDA-compliant. We regularly run samples through SGS or Intertek testing to verify food safety and heavy-metal compliance.
Our typical MOQ for custom lithographed tins ranges from 10,000 to 20,000 units depending on the size and shape of the design. This threshold allows us to optimize the high-speed printing and stamping setup, reducing unit costs for our clients.
Yes. We specialize in producing airtight metal packaging. We incorporate food-grade silicone, rubber, or specialized plastisol gaskets into the tin’s lid curls, creating a strong barrier that blocks moisture and prevents evaporation of active ingredients.
We operate 8+ automated production lines with high production capacities. Mold creation and sampling takes around 15–20 days, followed by mass production which is typically completed in 25–30 days. We also assist with logistics coordination for ocean freight, air express, or localized warehousing.
