Note:
  1. The tin coating weight is determined in accordance with specific end use applications. Tinplate with a heavy coating weight is used for making cans that require a high corrosion resistance or those used bare. Tinplate with a light coating weight is used for making cans that do not require so high a corrosion resistance or those used after painting or printing.
  2. With regard to other types of differential markings, please consult us.
Minimum average tin coating other tin standard coating weight
Range of nominal coating weight (m)per surface (g/M2) Minimum Average Coating Weight (g/M3)
1.0≤m<2.8 80%
2.8≤m<5.6 87%
5.6≤m 90%
Note:Designation of coating mass and niminal coating mass other than the sdtandard tin coating mass shall be subjected to the agreement ba the purchaser and the supplier, in this case, minimum average coating mass per surface shall be in acrodance with table.

Surface Finishes

Surface Finish Characteristics Code
Bright surface Glazed surface obtained after melting treatment of electro tinned smooth rawmaterial strip with extremely fie stone fiures by processing B
Stone surface Glazed surface obtained after melting treatment of electro-tinned raw material strip featuring certain oriented stone fiures. R
Silver surface Glazed surface obtained after melting treatment of electro-tinned raw material strip with rough matt surface. S
Note: Other than above maybe applied if agreed with between the purchaser and the supplier

Oiling

If no engagement, tinplate are electro statically oiled with DOS(2~20mg/M2) .

Usage Precautions for ETP

  1. 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
  2. Paintability, printability, solderability, and mechanical properties of ETP tend to deteriorate as time elapses after production. Use as soon as possible after delivery.
  3. Although ETP has excellent corrosion resistance, it tends to rust in a humid atmosphere. Use as soon as possible after unpacking.
  4. Tin is dissolved by a strongly alkaline solution. When using ETP for making cans for alkaline contents, paint the internal surface.
  5. As contents that contain sulfur cause blackening of the ETP surface, paint the internal surface.

Packaging

The products are packed in the manners shown below in order to prevent them for being damaged. A label that indicates the manufacturing history is affixed to the package. In addition，a service card in contained inside. The label and service can show the ollowing information on each packaging: specification， size，grade，number of sheets (for cut-to-length products)，weight，inspection number，coil number，and production date.
