Explore our certified child-resistant and custom metal tin containers, engineered for active botanicals, specialty teas, and food-grade safety.
CR Tin (Andylots Tin Box Packaging Co.,Ltd) is a streamlined, single-source professional supplier of specialized child-resistant and custom tinplate packaging. We seamlessly integrate child-resistant lock engineering, custom mold making, physical prototyping, rigorous compliance testing, and advanced mass production under one unified roof.
Our journey began in 2016, leading to the dedicated development of child-resistant locking tin boxes in 2017. Through nine years of persistent research, structural engineering, and pioneering market adaptation, CR Tin has accumulated over 70 certified child-resistant lock structures. These cover virtually all custom tin packaging formats requested by modern brands, allowing us to build a comprehensive, proprietary child-resistant locking architecture.
By combining high-end child-resistant capabilities with premium food-grade custom tea tin packaging requirements, our manufacturing plants deliver structural integrity, moisture barriers, and compliance assurances to major brands across North America, Europe, and Asia-Pacific.
Our operational scale and technical milestones ensure your customized tin packaging transitions seamlessly from design to retail shelves.
CR Tin is a highly specialized metal packaging manufacturer that engineers, customizes, certifies, and scales high-performance tin packaging for global markets.
Select from over 12 diverse child-resistant mechanism options alongside conventional high-end tea tin shapes including round, square, octagonal, and sliding mechanisms.
Our in-house design engineering department provides 3D digital renderings, technical structural analysis, and rapid 3D-printed plastic samples at zero initial cost.
Advanced sensor-driven automation paired with multi-stage manual inspections guarantees high-volume quality consistency, minimizing defect rates to under 0.05%.
Decades of collective industry expertise fuel our team’s unparalleled understanding of metal packaging. From airtight seals to complex mechanisms, we cover it all.
Why modern global tea brands are abandoning plastic baggies and cardboard cartons in favor of structurally advanced tinplate containers.
Teas, particularly organic green teas, white teas, and floral blends, are highly sensitive to UV light, moisture, and ambient odors. Custom tea tin packaging factories engineer hermetically sealed lids and inner collars to block out air and humidity, extending shelf life by up to 18 months.
With the global rise of active botanical infusions (e.g., CBD-infused, adaptogenic, or medicinal teas), there is an urgent need to comply with child safety laws. Our ASTM-certified child-resistant locking tin cases ensure that children are protected while retaining the premium appeal of a metal tin container.
Tin packaging functions as a keepsake long after the product inside is consumed. Custom printing techniques such as 3D embossing, debossing, spot UV, and holographic lacquers elevate a simple metal box into a collectable brand asset, enhancing customer lifetime value.
Adapting to global market shifts, our industrial roadmap focuses on three pillars of innovation to keep your brand at the cutting edge.
As the circular economy becomes a standard corporate mandate, we are developing lightweight tinplate utilizing high ratios of post-consumer recycled (PCR) steel. This achieves up to a 30% reduction in carbon footprint compared to virgin steel manufacturing, while keeping food-grade certifications (FDA/EFSA) intact.
The integration of digital identifiers onto steel packaging. Our research includes printing high-density laser-etched QR codes and embedding ultra-thin NFC microchips beneath the safe food lacquer. This allows consumers to track batch tracing, verify brand authenticity, and read organic farming reports with a single smartphone scan.
We are phasing out petrochemical plastics in our gaskets and air-tight plugs, replacing them with compostable, plant-based thermoplastic elastomers (TPE). This transition guarantees that the air-tight freshness system of our high-end tea tins remains zero-waste and microplastic-free.
Why sourcing your custom metal containers from our high-tech Chinese factories offers significant strategic benefits over fragmented local workshops.
Operating out of China's primary metalworking manufacturing hubs allows CR Tin to coordinate a highly responsive, end-to-end supply chain. This raw material advantage ensures immediate access to premium cold-rolled steel, custom alloy accessory suppliers, and highly specialized surface finishing workshops.
By implementing Smart Factory 4.0 standards, we have automated the traditional stamping, embossing, and lid assembly lines. Automated optical inspection (AOI) systems check every single tin box for dimensional compliance and cosmetic defects in real time. This high level of automation reduces structural variance, maintains strict quality control, and minimizes human errors, ensuring that your packaging fits seamlessly onto automated filling machines.
Furthermore, our unified warehouse facilities optimize shipping containers to reduce freight volume waste. Our proximity to deep-water shipping ports (Shenzhen and Guangzhou) guarantees efficient logistics, streamlined customs clearings, and fast global shipping timelines.
Securing cross-border shipments with structural documentation and strict regulatory compliance certifications.
Our child-resistant metal boxes are thoroughly tested to meet the standards set by the American Society for Testing and Materials (ASTM) for child-resistant packaging, ensuring full compliance for active teas and botanical products.
We build mechanisms that are proven to be child-resistant yet senior-friendly, matching the rigorous criteria of the Consumer Product Safety Commission (CPSC) to prevent accidental ingestion by young children.
Every sheet of tinplate and all internal coatings (including BPANI options) are fully certified food-safe under FDA Title 21 and European Union (EC) 1935/2004 regulations, ensuring that delicate loose-leaf teas are kept fresh and contaminant-free.
Additional child-resistant configurations, slide cases, and customized cubes tailored for high-end retail brands.
An objective, E-E-A-T driven checklist to guide your procurement and supply chain decisions.
When partnering with a custom tea tin packaging factory, purchasing agents must evaluate technical capabilities beyond basic per-unit costs. A structured assessment helps prevent compliance recalls and production bottlenecks:
1. Tooling & Custom Molding Expertise: Ensure your manufacturing partner designs and mills their own tooling. Self-managed mold production cuts down sampling cycles and ensures fine adjustments can be completed in-house rather than outsourced to third-party tooling shops.
2. Compliance Verification: Ask for official certificates of conformity matching ASTM D3475 and US CPSC standards. Genuine compliance reports should contain verifiable laboratory data, outlining child-resistant testing procedures and success metrics.
3. Raw Material Grade: Guarantee the tin packaging factory uses premium food-grade tinplate (typically electrolytically coated steel) with safe inner varnish and coatings. This prevents rust, preserves delicate tea flavor notes, and complies with FDA requirements.
4. Supply Capacity Scaling: A reliable supplier should offer flexible production adjustments, running multiple automated stampings to manage high-volume orders during seasonal demands without quality drops.
