CR Tin (Andylots Tin Box Packaging Co., Ltd) operates as a streamlined, single-source professional supplier specializing in certified child-resistant (CR) tin boxes. Our vertically integrated structural engineering pipeline manages everything from the initial child-resistant lock design, precision mold making, prototyping, safety-compliance certification testing, all the way to high-volume automated manufacturing.
Our journey began in 2017 when we anticipated the tightening of regulatory standards for child safety within the cannabis, confectionery, and pharmaceutical markets. Over nearly a decade of continuous research, development, and engineering iteration, CR Tin has patented and commercialized over 70 certified child-resistant lock configurations. Today, our catalogue satisfies and exceeds all compliance parameters in the metal packaging sector, establishing us as a global authority in child-resistant mechanism structures.
Our infrastructure is optimized to minimize time-to-market while guaranteeing strict adherence to international child-resistant directives.
Global brands face several hurdles when procuring custom rectangle tin packaging: shifting regional compliance mandates, unpredictable transport disruptions, structural flaws that compromise product freshness, and ballooning tooling costs. At CR Tin, we provide solutions that mitigate these sourcing risks.
We offer 12+ certified child-resistant designs, from push-button hinges to multi-step slider locks. These configurations are ready to integrate immediately into your existing supply chain without incurring additional tooling costs.
Our specialized prototyping department produces 3D structural renders within 48 hours, and physical 3D-printed resin prototypes within 5 days. This workflow allows you to evaluate mechanism performance before beginning metal fabrication.
We use automated visual inspection systems alongside on-line quality checks to ensure dimensional stability. We also coordinate third-party evaluations (SGS, Intertek) to confirm compliance with ASTM standards.
Developing a functional child-resistant tin container requires balancing two competing design goals: preventing access by children under 5 years old (CPSC 16 CFR § 1700.20 compliance) while ensuring the package remains accessible to adults and seniors.
Our custom rectangle tin boxes use a multi-action release protocol. This system requires two distinct physical inputs—such as a simultaneous pinch-and-slide or press-and-lift motion—to disengage the internal detents. To ensure performance over repeated uses, we use high-grade tinplate with specific elastic recovery properties, preventing the locks from deforming during regular operation.
Every brand requires unique aesthetic details. We offer extensive custom services that allow companies to align their packaging with their brand identity while retaining full child-resistant utility.
We support high-definition offset lithography, CMYK spot-color matching, textured matte coatings, glossy varnishes, and tactile 3D embossing/debossing to elevate on-shelf presence.
For herbs, flowers, and organic compounds, our airtight rectangle tins utilize custom-molded silicone gaskets and secure latches to lock in aromas and exclude moisture.
We produce eco-friendly paper pulp trays, molded starch inserts, metal dividers, and food-grade plastic inserts to protect products in transit and present them cleanly upon opening.
Operating out of China’s primary industrial hubs allows CR Tin to combine cost-efficiency with rapid production scaling. By locating our operations near raw material suppliers and key logistics corridors, we help our partners streamline their packaging supply chains.
Direct partnerships with major Chinese steel mills provide us with stable access to premium, food-grade electrolytic tinplate. This helps insulate our clients from global price volatility and ensures consistent quality.
Our facility houses 8 automatic production lines. Automated stamping, curl formation, and gasket assembly lines increase output, lower labor-related defects, and provide a competitive per-unit cost structure.
Our close proximity to major shipping hubs (Shenzhen, Guangzhou, Hong Kong) allows for convenient global distribution. We manage multiple shipping arrangements, including ocean freight, air transport, and door-to-door delivery with duty handling (DDP).
Safety compliance is a critical requirement in modern packaging design, not an optional feature. CR Tin implements a multi-tiered quality control program that monitors every production batch to verify performance and safety characteristics.
Our Quality Control protocols inspect incoming raw materials and monitor each stage of the stamping and forming process. Every batch must pass strict dimensional checks to confirm the child-resistant lock mechanism fits together securely. We test for hinge durability, pull resistance, and lock retention to make sure the boxes perform reliably after repeatedly opening and closing.
Our designs are tested and certified to comply with US Consumer Product Safety Commission (CPSC) child-resistant packaging standards.
Our facilities operate under ISO 9001 standards to maintain consistent production runs. We also adhere to food safety guidelines for products intended to contact edibles.
We construct our tins with food-safe raw materials and apply coatings that comply with FDA and EU food contact regulations (EC 1935/2004), confirming they are free of lead and BPA.
Rectangle tin boxes are highly versatile packaging containers, suitable for a range of regulated and premium industries across global markets.
In North America and Europe, strict state-level and national packaging mandates apply to flower and pre-rolls. Our crush-proof, child-resistant rectangle tins provide secure containment for retail sale.
For CBD gummies, lozenges, and vitamin tablets, our tins offer an alternative to single-use plastics. Custom-fitted silicone gaskets protect ingredients from exposure to air and light.
Our pocket-sized, slim slider tins are designed for active consumers. The durable locking hinges prevent accidental openings in pockets, purses, or travel bags.
The global packaging market is moving toward circular economies and reducing plastic use. Modern consumers favor brands that actively minimize waste, making metal packaging an attractive option for forward-thinking businesses.
Tinplate is 100% infinitely recyclable, losing no structural integrity during processing. As countries implement strict plastic taxes and extended producer responsibility (EPR) mandates, replacing plastic packaging with custom tin designs offers long-term compliance and environmental benefits.
CR Tin is also developing smart integration options. By incorporating QR codes and NFC chips directly onto the tin lid, brands can verify product authenticity, share batch testing results, and present supply chain histories directly to consumers.
When selecting a custom rectangle tin factory, procurement managers should verify the following parameters to ensure smooth project delivery:
Find answers to common questions regarding customization options, safety compliance, and shipping logistics for our tin boxes.
Our tin packaging is designed and tested to comply with US CPSC standards, including the ASTM D3475 protocol and 16 CFR § 1700.20 directives. We also utilize food-grade coating systems that comply with FDA and European Union food contact standards.
Yes. While using our existing child-resistant designs saves tooling costs, we can adjust length, width, depth, or latch features. Our design team creates custom CAD mockups and 3D printed samples for your review before building final molds.
Our standard MOQ for custom lithographed runs is 10,000 units per style. This volume is necessary to optimize our automated printing and stamping lines efficiently. We can occasionally process smaller quantities for early-stage market launches; please reach out to our team to discuss your project details.
We adjust the stiffness and positioning of the safety tabs so that opening the container requires a specific movement sequence rather than raw strength. This allows adults and seniors to access the contents easily while keeping children secure.
We can add custom-fit silicone, rubber, or polymer gaskets inside the lid rim, paired with a tension latch system. This creates a secure barrier that preserves freshness and prevents aroma leakage.
We deliver 3D designs within 2 to 3 days, and prototype samples within 10 to 12 days. Production mold construction and final sample approvals generally take 25 days, with bulk automated production completed within 30 days.
Yes. We procure our steel coil from reputable mills that supply certified sustainable, conflict-free metals. Our tins are constructed with recycled metal materials and are fully recyclable at the end of their lifecycle.
We handle all logistics methods, including FOB, CIF, DDU, and DDP. For DDP shipments, we manage customs clearances, duties, and local inland delivery directly to your warehouse.
