Why is edible oil packed in tinplate?

There are two shortcomings in the use of transparent plastic bottles for cooking oil.

First, plastics are slightly dissolved in oil and fat, which is harmful to human health;

Second, transparent packaging is easy to cause photooxidation of edible oil, shortening the shelf life, and the use of tinplate packaging is stable and protected from light, which can effectively solve these two problems. The edible oil cans are more healthy and have a shelf life of more than 2 years.

The specific performance is as follows: First, the tinplate can prevent moisture and deterioration, and secondly, it can enhance the shelf life, and it is not easy to produce harmful substances due to environmental changes. There is also a special coating on the tinplate for isolation and protection.
