Excellent recyclability: a model of environmental protection and
resource recycling
1. 100% recyclable metal properties
Electrolytic tinplate (tinplate) is a metal material with tin on
the surface of a low-carbon steel substrate. It is a completely
recyclable resource. There is no material degradation during the
recycling process and it can be recycled indefinitely
2. Efficient recycling process and low environmental load
No complex sorting is required during recycling. Magnetic
separation can separate metals and other impurities. The energy
consumption is only 1/3-1/4 of the original steel production, which
significantly reduces carbon emissions.
Cost-effectiveness: full cycle advantages from production to
recycling
1. Economic efficiency of materials and production
The thin specifications (0.14-0.5mm) of electrolytic tinplate can
meet the strength requirements of food packaging. The material
consumption is 80% less than that of glass packaging under the same
volume, and the transportation cost is reduced by more than 30%.
The industrial production process is mature, the tin plating layer
is uniform, the welding seal is good, and it is suitable for
large-scale automated canning. The unit production cost is 15%-20%
lower than that of aluminum cans.
2. Hidden cost optimization brought by long shelf life and low loss
The composite structure formed by the tin plating layer and the
steel substrate has excellent corrosion resistance. With the inner
coating, it can effectively block oxygen, moisture and food acid
and alkali corrosion, so that the shelf life of canned food can be
as long as 2-3 years, reducing food waste caused by deterioration.
The packaging container has strong rigidity and better resistance
to extrusion deformation than soft packaging. The breakage rate
during storage and transportation is less than 1%, further reducing
logistics loss costs.
3. Economic closed loop of recycling and reuse
Recycled tinplate can be directly used as a raw material for
steelmaking, replacing part of iron ore. Its market price
fluctuates with the metal market, but its stability is higher than
that of plastic recycled materials.
Dual fit of performance and application: the preferred solution for
food packaging
1,Safety and recyclability are unified: the tin plating layer is
safe and harmless in contact with food, and the recycling process
does not affect the purity of the material, ensuring that the
recycled product can still be used in the field of food packaging.
2,Balance between cost and environmental protection: Compared with
plastic packaging, electrolytic tinplate has significant advantages
in terms of marine debris pollution risk and chemical stability at
high temperatures. The unit packaging cost is only 5%-10% higher,
but the full life cycle cost is lower.
