Engineered for extreme performance, certified safety, and unmatched operational stability.
Shandong ClanZhao New Material Technology Co., Ltd. stands as the dedicated, wholly-owned global trade division of Linyi Xingguan Fine Chemical Co., Ltd. With a strict focus on the advanced fine chemical sector, we specialize in high-end aerosol product formulation, state-of-the-art automated manufacturing, and comprehensive cross-border shipping logistics.
Leveraging decades of chemical engineering expertise, our factory produces high-purity Card Type Gas (butane gas canisters) for international markets, securing partnerships with global retailers, industrial users, and emergency supply agencies.
A professional look at chemical formulations, pressure safety designs, and canister structure dimensions.
"Card Type Gas" canisters, commonly known as cassette gas canisters or bayonet gas cartridges, are pressure vessels containing liquefied petroleum gas, mostly high-purity butane. The term "Card Type" stems from the unique collar notch (or card slot) on the valve assembly that locks securely into portable stoves, heaters, and industrial blowtorches.
As a professional manufacturer, we engineer our canisters to withstand high internal pressures, utilizing a premium triple-seam dome structure and Countersink Release Vent (CRV) safety systems. In case of abnormal heat build-up, the CRV system prevents explosions by systematically venting pressure through microscopic openings on the collar rim, making it a critical safety option for commercial and recreational use.

Why leading global retailers trust Shandong ClanZhao & Linyi Xingguan for consistent volume manufacturing.
With our massive 100,000 square meter factory base, we house 10 automated aerosol filling lines. These systems integrate advanced propellants feedstocks, pressure diagnostics, and weight checking stations to produce up to 200,000 canisters daily.
Located in Shandong province, China’s industrial chemical core, we benefit from integrated logistics. Our access to tinplate printing, valve assembly components, and high-purity gas producers ensures a highly competitive cost-to-performance ratio for bulk contracts.
Safety is our top priority. Every canister undergoes automatic 55°C water bath testing to check for pressure leaks, alongside online vision checking of seam integrity and weighing audits.
Managing the complexities of Class 2.1 Dangerous Goods shipping and international standards.
Compressed gases are strictly regulated as UN1950 Dangerous Goods Class 2.1. We provide complete dangerous goods exporting compliance documentation, including MSDS, UN certificates, and certified double-walled outer carton packing to prevent transit stress.
Our gas products comply with international regulatory frameworks, including European EN 417 guidelines, North American DOT regulations, ISO 9001:2015 quality management standards, and regional chemical safety databases.
Through our international division, we handle complete custom clearance processing, port bookings, and Dangerous Goods marine shipping documentation, ensuring smooth deliveries across Europe, the Americas, Southeast Asia, and the Middle East.
Commercial Catering & Hotpot Dining: Indoor and outdoor restaurants rely on Card Type Gas canisters for direct tabletop cooking, hotpot stoves, and food presentation. Safety vents like CRV are essential for these indoor operations.
Outdoor Recreation & Glamping: The global boom in camping, overlanding, and back-country hiking has driven demand for lightweight, leak-proof portable butane gas canisters that perform well across different altitudes and cold climates.
Industrial Field Brazing & Plumbing: Contractors, HVAC technicians, and jewelers utilize bayonet butane gas canisters paired with specialized torch heads for light welding, heat-shrinking, and pipe-soldering operations.
Low-Carbon Green Propellants: Global regulations are pushing manufacturers toward highly refined gas formulations that minimize carbon emissions and lower harmful VOC release during use.
High-Pressure Lightweight Tinplate: Advanced metallurgy allows manufacturers to use thinner steel blanks without sacrificing structural yield strength, reducing shipping weight and lowering fuel usage during transport.
Advanced QR Code Traceability: Brand owners now require individual batch-tracking QR codes printed directly onto the canister body, offering consumers instant access to lab test sheets and manufacturing dates.
A transparent, step-by-step pathway from formula development to final customs dispatch.
Our team analyzes your local pressure regulations, chooses the appropriate valve type, and establishes the optimal butane/propane gas blend ratio.
We print your graphics onto high-quality tinplate steel utilizing multi-color processes, ensuring complete regional safety warnings are displayed.
The canisters undergo automated filling, crimping, sealing, and water-bath leakage testing to meet strict safety standards.
We manage safety booking arrangements, secure Class 2.1 containers, and manage logistics dispatch directly to your target port.
Answering key technical, logistical, and commercial inquiries from global procurement directors.
Under dry, temperature-controlled conditions (typically between 5°C and 30°C), a high-quality tinplate canister has a shelf life of up to 3 to 5 years. Store canisters away from direct sunlight, open flames, and moisture to prevent external oxidation of the tinplate steel body.
A CRV system is a safety feature built into the canister dome. If internal pressure rises abnormally, the countersink structure expands, opening micro-vents along the rim to release the gas safely. This prevents hazardous explosions in high-temperature environments.
Because automated tinplate printing and filling lines require significant setup, our MOQ for customized OEM packaging typically starts at 30,000 canisters (roughly one 20-foot full container load). Smaller test runs can be negotiated using standard stock canisters with custom labels.
Yes, provided the items share similar Dangerous Goods hazard categories (e.g., UN1950 aerosols). We coordinate consolidated container shipping for automotive sprays, household cleaners, and gas products, saving you import freight costs.
We maintain ISO9001 compliance. We utilize online automated check-weighers, inline high-temperature water baths to test seal integrity, and coordinate with third-party testing labs like SGS to verify gas purity and pressure stability.
