Explore our premium, certified child-resistant metal boxes specifically designed for confectionery, mints, pre-rolls, and gummies.
The global packaging sector is undergoing a profound paradigm shift driven by legislative mandates, sustainability commitments, and evolving consumer safety requirements. In the premium pre-roll, confectionery, and pharmaceutical sectors, generic packaging structures no longer suffice. Manufacturers are aggressively seeking high-barrier, child-resistant metal packaging solutions that guarantee fresh product preservation and satisfy strict national child safety codes.
As a leading OEM Joints Tin Container Factory, CR Tin (Andylots Tin Box Packaging Co.,Ltd) designs metal packaging systems that solve these compliance hurdles. Our products are engineered with robust child-resistant locking systems that conform to international safety protocols while projecting high-end brand value. Discover how metal packaging improves product shelf-life, protects active ingredients, and builds brand loyalty compared to single-use plastics.
"True quality is the perfect intersection of absolute safety, functional longevity, and structural elegance. Our focus remains on driving packaging performance through innovative, certified physical safety mechanisms."
Empirical metrics that validate our manufacturing leadership and product quality assurances globally.
How our engineering team ensures safety, durability, and cost efficiency across our entire product line.
We design multi-step locking systems—including side push-buttons, twist-to-unlock lids, and squeeze hinges—to satisfy strict child safety laws while remaining accessible for adult consumers.
Our engineering department delivers detailed 3D files and custom plastic test prints, helping clients evaluate ergonomic designs and lock mechanics before building final metal molds.
Our automated manufacturing lines perform automated sizing checks and inline optical inspections. Additional hand inspections ensure reliable hinges and consistent locking mechanics.
Developing packaging for joints and pre-rolls requires careful preservation of delicate essential oils and terpenes. Air exposure triggers oxidation, which degrades quality, decreases product efficacy, and reduces overall retail appeal. Traditional card stock packaging fails to provide long-term protection, while plastic options risk gas transfer.
CR Tin's premium metal containers are manufactured using high-quality electrolytic tinplate (ETP), coated with food-safe protective lacquers that prevent oxidation. We offer optional integrated food-grade silicone and thermoplastic elastomer (TPE) gaskets, transforming our metal boxes into airtight storage units that preserve freshness, locking in flavor profile and aroma.
Detailed design specifications, lock types, and customization capacities for mass manufacturing.
| Locking Type | Primary Application | Certifications | Key Material Attributes | Customization Range |
|---|---|---|---|---|
| Single Push-Button Hinge | Premium Mints & Small Pre-Rolls | ASTM D3475, CFR Title 16 | 0.23mm ETP, Internal Clear Varnish | Full Lithography, Embossed Textures |

| Twist-to-Lock / Click-Clack | Gummies, Lozenges, Edibles | US 16 CFR Part 1700.20 | Food-grade Tinplate, Silicone Gasket | Diameter variations, custom interior coating |
| Sliding Lock System | Pocket Joint Kits, Premium Vape Pods | Undergoing Certification Verification | Heavy-gauge ETP, High-tensile Springs | Debossed logos, anti-scratch exterior varnish |
For high-volume retail brands, consistency across millions of units is essential. Fluctuations in pressing depth or metal thickness can compromise child-resistant locking features, leading to compliance risks or assembly issues on the packaging line.
CR Tin has addressed these challenges by shifting away from manual production. Our facilities feature over eight automatic production lines that manage the sheet feeding, punching, stamping, and curling processes. This automation maintains strict dimensional control and minimizes defects, ensuring every single container functions exactly as designed.
We inspect all incoming raw materials, verifying tinplate thickness, lacquer adhesion, and hardware quality prior to production.
Dedicated quality teams perform structural and function tests on the assembly line, checking that each lock closes securely and opens smoothly.
Navigating child-resistant packaging regulations can be complex. In the United States, the Consumer Product Safety Commission (CPSC) enforces strict guidelines under the Poison Prevention Packaging Act (PPPA). To qualify as child-resistant, packaging must pass standard evaluation tests (such as 16 CFR § 1700.20) showing that children under 5 years old cannot access the contents, while seniors can easily open the container.
Our designs are built to succeed. Over 12 of our custom child-resistant metal container structures have completed official ASTM certification. We provide clients with full certification reports, streamlining retail onboarding and customs clearance. Partnering with CR Tin protects your brand from liability and distribution delays.
Whether you need pocket-sized tins for pre-rolls or large child-resistant containers for bulk products, our catalog offers certified options designed to keep your products compliant and secure in the marketplace.
CR Tin began focusing on child-resistant locking systems in 2017. What started as simple mechanical prototypes has grown into a comprehensive, proprietary collection of over 70 certified child-resistant designs. Our team has refined hinge geometries, wall tolerances, and button placements to build a mature packaging system.
Today, our product range supports all major retail styles in the specialty packaging market, including custom square boxes, round slider cans, and multi-lock containers. We handle the entire process in-house—from initial concept design and custom mold fabrication to functional testing and final mass production.
"By controlling the entire process from design to manufacturing, we help brands bring their packaging concepts to market quickly, affordably, and in full compliance."
Explore the operational steps that keep our metal container manufacturing efficient and high-performing.
8 years of developing child-resistant tins has generated a wide range of options, with most of our designs completing ASTM certification.
We lower production costs by simplifying child-resistant structures, automating assembly lines, and sourcing accessories from verified partners.
We verify accessory quality with strict inspection steps, keep production consistent on automated lines, and support independent quality audits.
Select from our library of structures or request custom sizing, utilizing our 3D design files, mockups, and artwork rendering services.
How we are preparing to meet the next generation of smart, sustainable, and high-performance metal packaging demands.
We are developing packaging using thinner, high-tensile tinplate steels to reduce overall weight and material footprint while keeping the physical strength required for child-resistant locking features.
Our engineering team is testing methods to integrate NFC (Near Field Communication) tags and laser-etched QR codes directly into metal containers, helping brands improve supply chain tracking and client interaction.
To replace traditional plastic sorting trays, we are designing biodegradable molded paper pulp and certified wood fiber trays to secure pre-rolls and joints cleanly inside the tins.
