CR Tin (Andylots Tin Box Packaging Co.,Ltd) is a streamlined, single-source professional supplier of child resistant tin boxes, integrating child resistant lock design, mold making and sampling, child resistant lock testing, and mass production. Understanding the critical challenges that brands face in the confectionary, baked goods, and cannabis industries, CR Tin began developing child resistant lock tin boxes in 2017.
After nine years of intensive research and development, combined with pioneering industry experience, we have proudly secured over 70 certified child resistant lock tin boxes. Our capabilities cover virtually all tin box packaging styles within the industrial sector, establishing our own unique, proprietary child resistant lock tin box ecosystem. By providing unparalleled "Information Gain" to our global procurement partners, we help businesses navigate complicated compliance requirements while elevating their brand experience.
How engineered metal containers outperform paperboard and plastic in freshness, longevity, and structural defense.
Brownies, specifically gourmet infused or high-moisture baked goods, present unique packaging challenges. The structural fat content and moisture levels require materials that do not degrade or leach over time. CR Tin utilizes high-grade Electrolytic Tinplate (ETP) consisting of thin sheet steel coated with a micron-level protective layer of pure tin.
All packaging components undergo rigorous screening to ensure compliance with global regulatory standard agencies including the US FDA, EFSA, and LFGB. Our interior protective coatings are formulated to be 100% BPA-free and food-safe, preventing grease migration and oxidization from compromising the taste profiles of premium brownies.
We provide a comprehensive OEM service to tailor every physical dimension and cosmetic attribute of your packaging. Our options include:
Pioneering safety engineering since 2017 to meet ASTM D3475 compliance regulations and maintain optimal adult accessibility.
Select from over 12 unique patented CR mechanisms, including press-tabs, squeeze-and-slide, and push-button configurations to match your brand's style.
Our dedicated structural team offers free custom designs, producing physical 3D mockups and rapid tooling models for verification prior to mass production.
We deploy strict automated validation systems at every assembly stage to ensure each latch operates smoothly while retaining full ASTM safety ratings.
In B2B purchasing, supply chain stability is everything. Our modern factory in China leverages smart manufacturing architectures to optimize production capacity and reduce costs without sacrificing quality. We operate 8+ automated lines that handle cutting, pressing, molding, and joint assembly with high precision.
By streamlining component procurement and partnering with premium accessory providers, we mitigate raw material price fluctuations. Operating under strict Quality Management Protocols ensures a low defect rate. This gives your brand a direct competitive edge in cost and delivery times.
A deep dive into regulatory alignment, supply-chain logistics, and strategic planning for international buyers.
Purchasing metal packaging from overseas requires careful planning. You must align production schedules with regulatory standards in your destination markets. In North America and Europe, testing under CPSC 16 CFR Part 1700.20 is required for products containing active ingredients like infused brownies. CR Tin provides full transparency throughout this testing process.
