In today's fast-paced international market, packaging acts as more than just a container; it serves as a critical junction for brand representation, safety compliance, and environmental stewardship. Custom metal box packaging has transitioned from a standard product storage shell into a high-technology asset, especially inside fields like pharmaceuticals, dietary supplements, organic botanicals, and high-end confectionery.
Regulatory constraints—most notably the stringent Child-Resistant (CR) packaging regulations outlined by the U.S. Consumer Product Safety Commission (CPSC) under 16 CFR § 1700.20 and international ISO 8317 standards—have driven brands to look beyond plastics. Recyclable metal, specifically electrolytic tinplate, presents a premium solution that aligns with global Net-Zero sustainability targets while providing a robust structural canvas for cutting-edge security mechanisms.
Integrating structural development, prototyping, certified testing, and high-volume lean production under one single source.
CR Tin (Andylots Tin Box Packaging Co.,Ltd) is a highly streamlined, single-source professional supplier of child resistant tin boxes. Our integrated workflow covers proprietary child resistant lock design, in-house mold tooling, mechanical sample fabrication, third-party child-resistant certification testing, and large-scale precision metal production.
Starting our dedicated research and development in child-resistant locking technology in 2017, we have compiled 9 years of pioneering experience. Today, we offer over 70 proprietary certified child resistant lock designs. Our IP portfolio covers virtually all metal packaging formats in the market, establishing an industry-leading, highly reliable child resistant lock tin box system designed primarily for highly regulated consumer goods markets.
Analyzing materials, regulatory compliance, and consumer interaction patterns.
With major consumer brands committing to eliminate single-use plastics by 2030, metal stands out due to its unique infinite recyclability. Electrolytic tinplate preserves its integrity throughout multiple recycling cycles, offering brands a verifiable circular lifecycle that boosts their ESG scoring.
The demand for certified child-resistant packaging has expanded from classic pharmaceutical products to recreational botanicals, edible concentrates, household cleaning pods, and concentrated personal care items. Certified compliance is no longer optional—it is a critical entry requirement for retail networks.
Amid physical shelf saturation and e-commerce noise, premium physical touchpoints are vital. High-definition lithographic printing, combined with localized embossing, debossing, and textured tactile varnishing, turns standard tins into collectible branded assets that drive customer retention.
At CR Tin, we run advanced manufacturing operations that bridge traditional craftsmanship with modern automation. China's integrated raw metal supply chain allows us to maintain stable, resilient sourcing for raw tinplate, high-speed custom tooling components, and specialized locking inserts.
By integrating automated high-speed pressing machinery, robotic assembly arms, and computerized optical sorting inspection devices directly into our production lines, we reduce human error, speed up cycle runs, and lower unit costs. Brands benefit from shorter lead times, consistent batch-to-batch alignment with strict specifications, and a reliable path to market.
8+ advanced automatic production lines running simultaneously to support high-volume global product launches without production bottlenecks.
Rapid CNC mold making processes that allow mockups to transition into final testing phases within 30 days.
A look at the specific parameters that make our custom metal packaging systems highly secure and cost-efficient.
We offer more than 12 distinct certified CR tin structures. This allows brands to select the design that best matches their product format, from small slide cases to larger hinged box profiles.
Our R&D team provides complimentary design services, 3D renderings, and 3D printed plastic samples. This helps you refine the lock mechanism and confirm its fit before committing to steel tooling.
Advanced automation and expert quality assurance teams monitor high-volume runs, verifying locking pressures and lid tolerances to ensure the metal cases perform reliably over time.
Our packaging designs undergo thorough testing processes. We hold certifications confirming compliance with ASTM D3475 and ISO child safety standards, making them retail-ready.
How we balance cost efficiency and mechanical performance for global brands.
We keep production costs manageable through refined child-resistant mechanics that reduce complex assembly requirements. Automated pressing lines speed up production, while a vetted, long-term accessories supply network ensures reliable, cost-effective components.
Our QA program includes inspection of incoming components and automated checks during production. Extra staff oversee manual assembly steps, and third-party inspectors verify every batch before shipment, providing independent quality reports.
We offer structural customizations tailored to your product needs. Our services include digital layout files for printing preparation, and physical samples to ensure the packaging meets your functional requirements before full production starts.
Exploring how custom metal boxes meet the technical demands of specific product markets.
Edible products need packaging that prevents exposure to air and moisture, keeping ingredients fresh. Our child-resistant metal cases can include food-grade silicone seals and food-safe interior coatings to protect product potency and taste.
Slim sliding boxes and hinged cases are ideal for protecting products during transport. We offer sizes with custom dividers, ensuring individual items stay securely in place and are protected from crushing.
Pocket-sized tins need reliable, easy-to-use child-resistant locks. We offer compact models that open with a squeeze-and-slide or double-button mechanism, providing security in a portable format.
Important details about compliance, materials, custom mold making, and production requirements.
Our child-resistant metal containers comply with US CPSC 16 CFR § 1700.20 standards and are designed in alignment with ASTM D3475 specifications. Our designs undergo testing by certified labs to ensure the locking mechanisms perform reliably for child safety compliance, facilitating smoother approvals for retail distribution.
We typically complete 3D structural drawings within 2 to 3 business days. Physical mockup samples from 3D printing can be prepared in about 7 days. Once the concept is approved, fabricating the custom steel production mold and producing initial pre-production metal samples takes approximately 20 to 25 days, allowing a new design to reach final approval stages within a month.
Yes. We can incorporate food-grade silicone, PVC-free plastisol liners, or specialized rubber gaskets within the inner neck or lid channels. This creates an airtight seal that limits oxygen and moisture exchange, helping to preserve product freshness and shelf life.
Yes. All varnishes, interior coatings, and offset inks we apply are food-safe. They undergo testing to confirm they are free from BPA and heavy metals, meeting food-contact standards for US and European regulatory jurisdictions.
We provide a range of surface decoration options. This includes high-resolution CMYK and Pantone offset lithographic printing, spot UV gloss, matte varnishes, and tactile finishes. Additionally, we offer multi-level embossing and debossing to add depth to your logos and branding elements.
Metal packaging is highly recyclable, and tinplate can be processed repeatedly without losing its physical properties. Choosing metal packaging helps brands reduce reliance on single-use plastics, supporting corporate sustainability objectives and matching consumer preferences for recyclable materials.
