Explore our foundational range of ASTM-certified, custom-engineered metal boxes designed specifically for sensitive edibles, mints, pre-rolls, and gummies.
CR Tin (Andylots Tin Box Packaging Co., Ltd) operates as a streamlined, single-source professional designer and manufacturer of child-resistant tin boxes. Our fully integrated facility manages the entire lifecycle of secure packaging, combining expert child-resistant lock design, precision mold making, rapid sampling, compliance testing, and high-volume mass production under one roof.
We began developing child-resistant lock tin boxes in 2017. Following nearly a decade of research, development, and pioneering experience, we have successfully commercialized over 70 certified child-resistant lock tin boxes, covering all major packaging styles in the industry. Through constant iteration, we have established our own unique, proprietary child-resistant lock tin box system, helping brands secure their products while maintaining premium brand appeal.
An in-depth analysis of regulatory shifts, material science breakthroughs, and environmental frameworks reshaping modern container engineering.
The global consumer goods market is undergoing a seismic shift. Rapid regulatory evolutions in the food, nutraceutical, and legalized cannabis sectors have made safety and compliance primary concerns. Historically, manufacturers relied heavily on plastic packaging. However, changing consumer behaviors and strict environmental laws make single-use plastics less desirable. Enter premium metal tinplate packaging—specifically engineered with child-resistant (CR) properties.
Modern consumers demand packaging that preserves product freshness, matches premium branding, and remains safe for families. For businesses, edible metal packaging represents a high-integrity choice. It offers an absolute barrier to light, oxygen, and moisture, extending the shelf-life of delicate compounds like cannabinoids, active nutraceuticals, and organic functional foods, while reducing reliance on chemical preservatives.
Not all metal packages are created equal. High-quality edible metal tins are fabricated from Electrolytic Tinplate (ETP) or tin-free steel, coated with food-safe protective lacquers. The interior coatings must comply with FDA regulations (21 CFR 175.300) and European Food Safety Authority (EFSA) directives to prevent metal migration into food products. Modern formulations use BPA-NI (Bisphenol A Non-Intent) epoxies and organosol linings, ensuring zero interaction between the packaging and the edible contents inside, even in high-temperature or humid environments.
Metal packaging is highly compatible with the circular economy. Tinplate is infinitely recyclable without losing its physical properties. According to European and global recycling statistics, metal packaging leads recovery rates among all packaging materials. Magnets make tinplate easy to sort in recycling streams. Choosing metal packaging allows brands to lower their carbon footprint and appeal to eco-conscious consumers.
Discover how our manufacturing capabilities, dedicated engineering teams, and strict quality control processes support your brand's growth.
Select from over 12 distinct certified child-resistant structural styles, including slide tins, hinged tins, and push-and-turn lids. This variety helps you find the right style for your target audience.
We provide full creative support, from 3D modeling to physical plastic prototypes, helping you test and refine your ideas before investing in expensive steel molds.
Automated visual inspection lines work alongside manual quality checks to ensure consistent dimensions, clean prints, and reliable child-safe locks across large production runs.
Our engineering team brings decades of combined experience in tinplate construction and mechanical design. We use this experience to create child-resistant closures that are simple to manufacture, cost-effective, and intuitive for adults to open.
We work with brands at all stages, from small regional startups to multinational consumer goods companies. Our product line includes airtight tins for flower, compact cases for mints, and larger boxes for gummies and wellness products. We design each package to protect the safety of curious children while keeping the contents accessible to adult users.
Our products are engineered to meet strict international safety standards:
We work closely with your product teams to design, prototype, and manufacture custom metal packaging that fits your brand identity.
We translate your project ideas into 3D CAD drawings. Our engineers analyze child-resistant locking features, metal thickness, and tolerance levels to ensure reliable performance and consistent opening force.
Using high-precision 3D printing and mock-ups, we create physical samples to verify the box dimensions, closing feel, and internal volume before tooling begins.
Our in-house mold department produces custom stamping dies. By handling tooling internally, we keep costs low and complete the process within 30 days.
Tins are finished with custom lithographic printing, spot-UV, embossing, or debossing. We perform final functional checks to ensure the child-resistant closures work reliably under high-speed production conditions.
How CR Tin optimizes material costs, guarantees product quality, and supports custom packaging requirements.
Our packaging systems undergo third-party certification testing to meet child-resistant and senior-friendly standards. By using structural steel designs over plastic components, we improve durability and ensure the child-safe mechanism remains functional over the lifetime of the product.
We focus on simplifying tinplate assembly to keep production costs competitive. By using automated production lines and collaborating with trusted accessory suppliers, we offer high-quality child-resistant packaging at affordable price points.
Our QC team inspects incoming raw materials, monitors active production lines, and checks finished tins. Automated stamping and visual systems help us maintain tight tolerances, and we welcome third-party pre-shipment inspections.
We support a variety of custom details, including 3D renders, physical plastic mock-ups, and special finishes like matte, glossy, metallic, or spot-UV varnishes. Our team works to match your brand's specific visual and physical requirements.
How different consumer segments use our custom child-resistant metal packaging solutions.
State and federal regulations require cannabis-infused chocolates, cookies, and gummies to use child-safe packaging. Our ASTM-certified slider and hinged tins meet these legal standards while helping brands stand out on dispensary shelves.
Vitamins, herbal tablets, and dietary supplements benefit from the moisture protection of metal. Our air-tight screw-top and hinged tins keep sensitive ingredients dry and secure from children.
Pre-rolled herbs need packaging that prevents physical damage and controls odors. Our hinged tin cases feature silicone gasket liners that provide an airtight seal to lock in freshness and prevent odors from escaping.
High-end confectionery products require durable, pocket-sized containers. Our slim slide-lids and micro-hinged boxes protect mints from crushing while fitting easily into a pocket or purse.

A tin box is child-resistant when it features a closure mechanism that requires two distinct motions to open (such as press-and-turn or push-to-slide). These locks are designed to be difficult for children under 5 to operate, while remaining straightforward for adults.
Yes, our internal varnishes and coatings are FDA-approved (21 CFR 175.300) and BPA-NI (Non-Intent). They are safe for direct food contact and will not migrate or react with acidic, oily, or moisture-sensitive contents.
We supply pre-certified shapes that already have ASTM certificates. If you develop a custom size, we can coordinate with third-party testing labs to certify your unique closure under CPSC 16 CFR Part 1700.20 protocols.
Our standard MOQ for custom lithographed child-resistant tins typically ranges from 10,000 to 30,000 units, depending on the container dimensions and styling requirements. For standard shapes with custom labeling, lower MOQs are available.
Yes, we can equip our child-resistant tins with silicone, PVC-free, or food-safe TPE gaskets. These form a tight seal that prevents dry foods and herbs from drying out or degrading due to oxygen exposure.
