Tinplate(SPTE) is an iron sheet coated with a layer of tin, which is not easy to rust. It is widely concentrated in food cans, beverage cans, spray cans, cosmetics, paint cans, chemical cans, storage cans, batteries, stationery, etc.
Shanghai Zhengshang Industrial Co., Ltd. is a professional tinplate steel coils/sheets manufacturer factory in China.

The main advantages of tinplate are:
- Soft, easy to bend, stretch, punch.
- It is lighter in weight than glass jars and not easily broken.
- Easy to carry, transport and keep.
- It has good thermal conductivity, short sterilization time, and is not easy to break when the temperature changes sharply.
Wide Application of Tinplate
Tinplate is widely used in the field of packaging, especially in the field of food packaging. Nowadays, the packaging materials of metal cans are basically tin-plated iron sheets. The tin-plated layer has strong corrosion resistance, and the steel ensures the mechanical strength of the packaging.
Food safety is an important indicator of tinplate manufacturing. In order to ensure the safety level of the product, every process is required to meet safety and hygiene standards. We formulate OPRP and list CCPs to ensure product quality and safety by finding hazards from biological, chemical, and physical factors from raw and auxiliary materials and process flow diagrams. At the same time, it is necessary to ensure that the tinplate produced is not rusted or perforated. Zhengshang Group operates quality management system, environmental management system, food safety management system, etc., and provides tinplate products that meet the safety management system for the packaging industry.
According to the needs of customers, SPTE steel is packaged in rolls or sheets (specially, it can be cut into strips). The surface is covered with PET film. Then use waterproof paper packaging, iron packaging. For the stability of the packaged product during transportation, a fumigated wooden pallet will be used to fix it.
