Часто задаваемые вопросы

What certifications should a square tin can supplier hold for aerosol use?

Надежный square tin can for industrial or personal care aerosols must meet layered compliance:

Транспорт & безопасность

DOT certification for hazardous goods movement
UN packaging standards confirming drop and pressure tests

Материал & chemical control

REACH regulations covering internal lacquer and external decoration inks
Pressure equipment directive validating tinplate construction strength

Дисциплина процесса

ISO quality management guiding metal stamping, side seam welding, обжим клапана, and leak testing

Без этих, seam integrity and клапан аэрозольного баллончика system safety become a gamble no brand can afford.

How is corrosion resistance evaluated in square profile aerosol cans?

Corrosion resistance protects both product and reputation. Testing usually combines lab exposure and real-use simulation:

Salt spray testing on tinplate steel to assess coating durability
Chemical immersion checks for internal lacquer performance
Adhesion and ductility checks after internal coating application

For automotive care or pest control sprays, chemical compatibility with propellant gas and dip tube material is critical. A weak internal layer can quietly compromise seam integrity and material gauge strength over time.

Why is precision in metal stamping and neck finish so critical?

A square profile demands accuracy. Small deviations echo through the entire can:

• Uniform neck finish ensures secure valve crimping

• Accurate side seam welding prevents distortion under pressure

• Controlled material gauge supports stable stacking and clean edges

• Consistent lithography printing keeps external decoration aligned

In personal care aerosols or household products, visual symmetry matters as much as pressure safety. A misaligned square tin can is noticed instantly.

What should be reviewed during a factory quality audit?
