Coffee tins are better than coffee glass jars

   Coffee cans are roughly divided into two types: glassware and tinplate cans. Generally, the shelf life of glass cans of coffee is about 8 months, while the shelf life of tinplate coffee cans can be as long as two years.

   Many people have to ask, why the shelf life of tinplate cans can be so long, is there preservatives added in it? SZM tells you that the reason why the shelf life of tinplate coffee cans is so long is that coffee cans made of tinplate have the following advantages. 

1. The opacity of the coffee tin can

the opacity of tinplates makes the preservation rate of vitamin C the highest. In addition to causing food deterioration reactions, light can also cause changes in protein and amino acids. Vitamin C is more likely to interact with other food ingredients when exposed to light, resulting in a large amount of loss.

2. Good airtightness of the coffee tin cans

 the oxygen transmission rate of the container directly affects the browning of the juice and the preservation of vitamin C. Tinplate cans can effectively block the reaction between food and air, which is very important for the preservation of nutrients and sensory quality.

3. The anti-oxidation effect of the coffee tin can.

  The tin on the inner wall of the coffee tin will interact with the oxygen remaining in the container during filling, reducing the chance of food ingredients being oxidized. The shelf life is thus extended. Because of these properties, tinplate cans provide a closed system that completely isolates environmental factors, preventing food from deteriorating due to light, oxygen, and moisture, and will not be weakened due to aroma penetration or be polluted by environmental odors. The storage stability of food is better than other packaging materials, the preservation rate of vitamin C is the highest, and the preservation of nutrients is also the best.

The high temperature sterilization and sterilization process of tinplate cans can ensure the hygiene of food, minimize the possibility of corruption, effectively prevent health risks, and also meet people's needs for convenient and fast use of coffee tins. Tinplate cans It is the first choice for packaging containers for chocolate, tea, biscuits, health care products and candy.
