Tinplate Steel Coil For Aerosol Containers

1. Introduction

• What is tinplate? 

• Tinned steel sheet referred to as tinplate, commonly known as tinplate, is a product made of tinning on a thin mild steel plate. The tin plate produced by the hot dip process is called the hot dip tin plate, and the tin plate produced by the electroplating process is called the electroplated tin plate.

• Because about 98~99.8% of the weight of the tin plate is steel, it is a coated steel variety that belongs to metallurgical products.

Chemical composition of tin

The purity of tin sold on the market is mostly between 99 and 99.95 percent, and the impurities are mainly lead, arsenic, antimony, bismuth, copper, iron, sulfur and so on. The quality of the metal tin used in the production of tinplate must meet the international standard GB728, No. 2 tin or above.

We are professional tinplate sheet coil manufacturer, located in Shandong province. We produce a line of tinplate sheet that is compliant with GB/T 2520-2000, JIS G3303-2002 and DIN EN 10203-1991 standards. Currently, our tinplate is extensively used for packaging food, beverages, paint, oil, aerosols, and other everyday items. It is also used for bottle caps, auto parts, and batteries.

2. Tinplate characteristics

Advantages of Food Cans

Hygienic: Provide excellent and non-toxic barrier properties to protect food products from

impurities, bacteria, moisture, light, and odours.

Safe: Low weight and high strength make food cans easy to ship and store .

Eco-friendly: Offer 100% recyclability; and significant cost benefits compared with aluminum.

3.  Mechanical Properties of DR Tin Mill Products

• Temper after single reduce JIS G3303-2008

• Temper after Double Reduce(DR)JIS G3303-2008

4. Formability
Deep drawing
Some types of tinplate display excellent deep-drawing property because of a high Lankford coefficient (or coefficient of anisotropy) associated with low in-plane anisotropy, which ensures near-identical performance irrespective of the orientation of the deformation in relation to the rolling direction.

Bending, rolling
Thanks to its high level of ductility (for steel with low mechanical properties) and near-isotropic properties, tinplate can withstand severe bending or rolling.

Expansion, embossing, beading
Tinplate is well suited to mechanical, pneumatic or hydraulic expansion. Its expansion capacity by pneumatic or hydraulic means can be up to 30%.

5. Usage Precautions for ETP

• As ETP is covered by soft metallic tin coatings, due precautions should be taken not to cause scratches by rough handling or vibration during transportation.
• Paintability, printability, solderability, and mechanical properties of ETP tend to 收deteriorate as time elapses after production. Use as soon as possible after delivery.
• Although ETP has excellent corrosion resistance, it tends to rust in a humid atmosphere. Use as soon as possible after unpacking.
• Tin is dissolved by a strongly alkaline solution. When using ETP for making cans for alkaline contents, paint the internal surface.
• As contents that contain sulfur cause blackening of the ETP surface, paint the internal surface.

7. TINPLATE COILS

Properties
A. Tinplate is characterized by its thin gauge, which is between 0.13mm and 0.49mm.
B. Tinning of the tinplate is achieved in a continuous electrolytic process.

8. APPLICATIONS 

Typical Applications including:

A. Consumer Packaging and Industrial Packaging

TINPALTE

• ETP is primarily used for packaging foodstuffs and beverages, but it is also used in containers

for oils, grease, paints, polishes, chemicals and many other products. Aerosol containers and

caps and closures are also made from ETP.

TFS

• TFS are most frequently used for can tops, screw and lug caps, snap and press-on closures and shallow-drawn food cans.
• Miscellaneous

B. in Electronics

– Electrodes, Cable tape, Magnetic screen covers, etc.

in Engineering

– Automotive oil filters, Automotive air filters, Gaskets, etc.

in Construction

– Gas meter internal components, Heat exchangers, etc.

9. Packing and Marking

Offers coils and sheets, coil packed in a vertical form or a horizontal.

A label that indicates the manufacturing history is affixed to the outside of the packaging. In addition, a service card is contained inside.
