The history the tinplate cans
The beginning of tin can historyThe glorious history of tin cans can be traced back to 1795, when the French government under Napoleon offered a reward of 12,000 francs for the marching army to find available food preservation methods. Previously, soldiers often died of starvation. Napoleon lamented that "an army travels on its stomach". This is exactly the same as the Chinese proverb: "The soldiers and horses are not moved, the food and grass go first." Therefore, the army is brave. The prerequisite for warfare and colonial expansion is to find a way to preserve food for a long time.
