Why do most high-end products use packaging iron boxes?

Now, many products have started to use outer packaging. At present, the upper packaging on the market can be roughly divided into three categories: plastic packaging, carton packaging, and iron box packaging. But with the changes in social economy and people's concepts, the utilization rate of iron box packaging is increasing. Why is this? Today, the Iron Box Factory will explain it to us. 

Plastic packaging is a traditional packaging method in the past. It has long occupied a major share of packaging. Its advantages are some irreplaceable advantages such as light weight, good toughness, excellent barrier function, corrosion resistance, chemical laziness and excellent molding and processing functions. Plastic packaging is the simplest of all packaging materials, and is easy to form and easy to process. When processing, you can get containers of different shapes by replacing the mold, which is convenient for mass production. The disadvantage of plastic packaging is that it will deform at high temperatures, easily oxidize and become brittle, which is not conducive to long-term storage. One of its most fatal flaws is environmental pollution, which is also the fundamental reason why plastic packaging is gradually being screened.

Iron box packaging, as a newly bulging packaging material, has shined in recent years mainly because of the excellent pressure resistance, plasticity and high temperature resistance of tinplate boxes. A particularly important point is that iron boxes will not pollute the environment. This is particularly important today when customers are increasingly aware of environmental protection.

1) Light opacity: In addition to causing food spoilage, light will also cause changes in food quality and grade. Tea leaves are more likely to deteriorate under light (especially green tea). The opacity of tin pills makes the tea preserved rate high, preserving the original juice, color, taste and fragrance of the tea.

2) Excellent sealing: The barrier properties of packaging containers to air and other volatile gases are very important for the preservation of nutrients and sensory quality. Metal cans with low oxygen permeability can better preserve tea leaves, which is also the characteristic of iron cans.

3) Reduction effect of tin: The tin on the inner wall of tinplate will be related to the oxygen remaining in the container during filling, reducing the timing of food ingredients being oxidized. The reduction effect of tin is also an extension of the shelf life of tea.

In addition, the packaging iron box also has a heat insulation function, which completely blocks the influence of environmental factors, prevents food from discoloring due to light, oxygen, and moisture, and will not weaken or deteriorate due to fragrance overflow. Affected by environmental odor. Contamination and taste changes, so food storage is more stable than other packaging materials.
