The opacity of tinplate and the effect of tin on the iron with the oxygen remaining in the tin box during filling. This reduces the possibility of oxidation for the contents of the package and is essential for its preservation; the metal of tinplate The ductility is good, so that the more complex container can be produced with high precision and high speed. The good rigidity enables the produced tin boxes to withstand collisions, vibrations and stacking, which is convenient for transportation and storage; it is easy to recycle and can be recycled. The environmental protection of tinplate is also better than plastic and paper packaging. The above characteristics have made tinplate packaging chosen by many companies as their product packaging materials. The most important thing is that its metallic texture will reflect the preciousness that plastic packaging and paper packaging do not possess.
