High-precision engineered metal containers compliant with US 16 CFR § 1700.20 and international safety protocols for premium product protection.
CR Tin (Andylots Tin Box Packaging Co., Ltd.) stands as a streamlined, single-source professional OEM carrier manufacturer specializing in certified child-resistant tin boxes. We seamlessly integrate creative locking design, precision mold making, rapid sampling, physical compliance testing, and high-volume automated manufacturing.
Initiating specialized child-resistant lock development in 2016–2017, CR Tin has accumulated over nine years of pioneering R&D experience. Today, our engineering portfolio features over 70 certified child-resistant lock tin designs, spanning across virtually all structural tin packaging styles in the global marketplace. We have successfully established an authoritative, proprietary child-resistant lock tin ecosystem tailored for high-stakes consumer products.
Decades of collective structural expertise fuel our team's continuous innovation. Whether serving emerging enterprise brands or global market leaders in pharmaceuticals, botanical extracts, and functional confectioneries, we deliver airtight, sustainable, and compliant metal carrier systems.
Strategic shift toward sustainable metal carriers, stringent safety regulations, and premium branding imperatives.
Global ESG mandates and consumer backlash against single-use plastics are forcing top-tier consumer brands to pivot toward 100% infinitely recyclable metal containers. Electrolytic Tinplate (ETP) offers zero-degradation recycling, positioning custom tin carriers as the gold standard for eco-conscious enterprises.
Regulatory bodies across North America (US CPSC 16 CFR § 1700.20, ASTM D3475) and Europe (ISO 8317) have intensified enforcement regarding child poison prevention. OEM carriers must demonstrate dual-action safety mechanisms that prevent child access under 5 years while keeping senior usability seamless.
Advanced product formulations require superior environmental barriers. Modern metal carriers integrate food-grade silicone gaskets and engineered hermetic seals to guarantee Zero Moisture Vapor Transmission Rates (MVTR) and preserve volatile compounds, freshness, and shelf stability.
Packaging is no longer merely a container—it is a critical compliance layer and brand asset. Partnering with a specialized OEM carrier manufacturer eliminates structural failure risks during regulatory audits and enhances point-of-sale brand equity.
Integrating 8+ years of specialized CR tin packaging engineering to deliver cost reduction, rigorous quality control, and rapid customization.
Rigorous engineering standards ensuring precise lock retention, structural durability, and environmental resistance.
