Φ45mm Internally Coated Necked-in Aerosol Can

A slim can with an internal coating — built for formulations that need extra protection.

The Φ45mm internally coated necked-in aerosol can is designed for products where the contents may react with bare tinplate. The internal coating creates a protective barrier between the metal and the formulation, helping to preserve product integrity and extend shelf life.

Manufactured by Guangdong Sihai Iron-Printing and Tin-Making Co., Ltd., this can belongs to our Φ45mm necked-in series (height range 85–180mm), the slimmest format in the Sihai 3-piece range. It is a suitable choice for personal care, specialty, and technical aerosol products where corrosion resistance matters.

Working With Sihai

Sihai is an integrated manufacturing partner rather than a single-line can supplier. Our role is to match your specification to the right can format, produce it in-house, and deliver it with the packaging and documentation your shipment requires.

What we handle in-house:

  • Iron cutting — flat cut and wavy cut

  • Iron printing — film and printing design, coating, and printing

  • Pressing — cone and dome production on automated lines

  • Can making — slitting, welding, drying, can sealing, leak testing, packaging

  • Internal coating — applied according to formulation requirements

  • Mold development — designed and built in-house

  • Laboratory testing — independent verification for each batch

What we need from you:

  • Can size, height, and estimated order quantity

  • Artwork files and color references

  • Internal coating requirement and formulation details

  • Pressure version preference (standard or high pressure)

  • Packaging preference (pallets or cartons)

  • Destination and delivery requirements

What you can expect:

  • Specification confirmation and quotation

  • Print feasibility review and sampling

  • In-house production and batch testing

  • Export-ready packaging in pallets or cartons

  • Short and on-time delivery supported by automated lines


How Each Batch Is Checked

 
 
Stage What Happens
Incoming Material Tinplate thickness and surface quality checked against specification
Coating Inspection Internal coating coverage and adhesion checked
In-Process Dimensional checks during cutting, printing, pressing, and can making
Pressure Testing Deformation and bursting tests on sampled cans from each batch
Leak Testing 100% inline leak detection on the can-making line
Final Inspection Visual, dimensional, and functional checks before packaging

Manufactured under ISO9001:2015 and GB13042-2008, with independent laboratory support for routine and customer-specific testing.
