Tea, in addition to gift box packaging, the most common is iron box packaging. Have you ever wondered why? In fact, just because the iron box has these four advantages!
1. Opacity
Light has always been one of the factors causing food deterioration. Tea is also easy to deteriorate when exposed to pipeline irradiation. The opaque tinplate can effectively improve the preservation rate of tea and ensure the original juice, color, taste and aroma of tea.
2. Good sealing
The barrier of packaging container is very important for the preservation of tea. The oxygen permeability of iron cans is low, which can better preserve tea.
3. Reduction of tin
The tin on the inner wall of the tinplate will react with the oxygen remaining in the container during filling, reducing the chance of food components being oxidized. The reduction of tin is also the extension of the storage life of tea.
In addition, tin cans also have a heat proof function, which is completely isolated from the influence of environmental factors, will avoid the qualitative change of food due to light, oxygen and moisture, and will not fade due to aroma overflow or change the taste due to environmental odor pollution. Therefore, the stability of food storage is better than that of other packaging materials
