Explore our flagship certified air tight and child resistant tin series, precision engineered to safeguard product freshness and comply with strict international regulatory standards.
Navigating regulatory changes, environmental pressures, and preservation challenges in B2B product containment.
Global markets, particularly North America and the EU, enforce rigorous child-resistance protocols. In the US, compliance with ASTM D3475 and CFR Title 16 Part 1700.20 is non-negotiable for cannabis, concentrates, pharmaceuticals, and concentrated nicotine delivery products. Forward-thinking brands are turning to premium metal containers that balance complex child lock mechanics with accessible Senior-Friendly designs.
Single-use plastic packaging is facing severe legislative and consumer backlash. Aluminum and tinplate possess an infinite recycling loop without material degradation, positioning metal tin cans as the preferred medium for ESG-focused enterprises. Utilizing tin-based packaging lowers carbon footprints and strengthens circular supply chains, aligning with contemporary global environmental mandates.
Product degradation due to exposure to moisture, light, and ambient air is a critical concern for organic, chemical, and edible products. True airtight containment is vital for protecting active volatile compounds, maintaining freshness, and preventing premature spoilage. Industrial-grade hermetic tin packaging secures long-term chemical and physical integrity for high-value cargo.
Achieving a reliable hermetic seal in high-volume, automated tin production requires advanced structural design and high-quality materials. At CR Tin, we use food-grade, high-tensile tinplate coated with customized polymer compounds to prevent oxidation, rusting, and chemical migration.
Our custom gaskets use premium, BPA-free silicones and food-safe plastisols tailored to fit precise grooves in the lid. When locked under pressure, these gaskets fill micro-voids, blocking oxygen transmission (OTR) and moisture vapor transmission (MVTR).
We optimize the relationship between the lock's tension and the compression of the seal. This ensures the container remains child-resistant while still providing an airtight barrier that preserves the aroma and freshness of sensitive contents over long storage periods.
Our integrated manufacturing system scales smoothly from conceptual design and rapid 3D prototyping to automated mass assembly and strict quality assurance.
CR Tin (Andylots Tin Box Packaging Co., Ltd) is a streamlined, single-source professional supplier of child resistant tin boxes.

After nine years of research and development and pioneering experience, we have over 70 certified child resistant lock tin boxes, covering all tin box packaging styles in the industry, and have established our own unique child resistant lock tin box system.
Decades of collective industry experience fuel our team’s unparalleled tin structure knowledge, fresh CR Tin ideas, and consistent quality in our premium and unique CR tin box packaging. Whether you are new to cannabis or deeply seasoned, we are here to support and guide you to choose and use our unique tins. From airtight CR tin, recycling material to high-end, unique tin structure, we have your needs covered.
Our design approach targets three key areas: optimizing manufacturing costs, enforcing strict quality control, and offering complete aesthetic customization.
How we turn custom design concepts into fully certified, shelf-ready metal packaging in under 30 days.
We analyze your product specs, target audience, and local regulatory requirements to select the best locking mechanism.
Our engineers create detailed 3D CAD files and supply photorealistic renderings for branding and structural validation.
We generate physical samples using plastic modeling and rapid metal tooling to verify the lock's feel and seal tightness.
We initiate automated high-volume production, incorporating real-time defect scanning and quality checks.
Optimizing barrier performance, safety, and brand style across primary consumer sectors.
Cannabis packaging requires strict child resistance alongside excellent freshness preservation. Exposure to oxygen and light degrades delicate terpenes, turning THC into CBN and diminishing value. Our airtight child-resistant tins keep flower, pre-rolls, and concentrates fresh while complying with global regulatory safety standards.
High-sugar gummies are prone to melting and moisture absorption, while infused gummies must be kept safely away from children. Our tin systems use specialized food-grade coatings and airtight seals to block humidity. This keeps gummies separated, maintains their flavor, and prevents them from drying out or sticking together.
Medicines, capsules, and health supplements need consistent protection against light, moisture, and contamination. Metal tin packaging provides an effective barrier that plastic bottles cannot match. Our certified child-safe closures offer a dependable barrier for over-the-counter and prescription medicines.
Selling into regulated markets requires verified compliance. CR Tin holds ASTM D3475 and CPSC certifications, which are verified by independent US testing agencies. This simplifies customs clearance and eases the path to market for our customers.
We also plan ahead for shifting environmental regulations. Our engineering roadmap focuses on plastic-free airtight seals, incorporating biodegradable and highly recyclable metal materials to replace standard plastic liners. This ensures our packaging remains compliant, functional, and environmentally sustainable.
