Why tinplate metal the first choice for many metal packaging

Tinplate metal is one of the most common metal items we have. We can see various styles of tinplate cans on supermarket shelves.Most children’s and adult food packaging comes in tinplate cans.

Many of the cans we come into contact with in our daily lives, such as canned meat, milk powder cans, tea cans, candy cans, etc., are made of tinplate metal. Why do so many products choose tinplate as packaging? Here we will show you why tinplate cans are used to package food.

1. Opaqueness

In addition to causing food deterioration reactions, light can also cause changes in proteins and amino acids. Vitamin C is more likely to be lost when exposed to light. The opacity of tinplate cans makes the preservation rate of vitamin C the highest.

2. Good sealing

The barrier property of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. Comparison of various juice packaging containers shows that the oxygen permeability of the container directly affects the browning of juice and the preservation of vitamin C; metal cans, glass bottles, aluminum foil laminates, and paper boxes with low oxygen permeability have better preservation of vitamin C, among which tinplate cans are the best.

3. Reduction effect of tin

The tin on the inner wall of tinplate will react with the oxygen remaining in the container during filling, reducing the chance of oxidation of food ingredients. The reducing effect of tin has a good preservation effect on the flavor and color of light-colored fruits and juices. Therefore, juice cans packed in unpainted iron cans have better nutritional preservation than juice cans packed in other packaging materials, with less browning, better flavor quality acceptance, and thus longer storage period.

1. Good mechanical properties:

Compared with other packaging, tinplate cans are much stronger, more rigid and less prone to breakage. They can be used not only for small sales packaging, but also for large transport packaging.

2. Excellent sealing:

Tinplate cans have better sealing than any other materials, including air barrier, moisture-proof, light-shielding and flavor-preserving properties, and reliable sealing, which can protect the product to the maximum extent.

3. Mature technology:

The production technology of tinplate cans appeared very early, and its technology is quite mature, and the supporting production equipment and tools are also mature, which can greatly improve production efficiency and meet the packaging needs of various products.

4. Different shapes:

Tinplate cans can be made into various shapes according to different needs, such as square cans, oval cans, round cans, horseshoe-shaped, trapezoidal, octagonal, etc., which not only meet the packaging needs of different products, but also make tin can packaging more varied.

5. Recyclable and reusable

It is green, environmentally friendly, decomposable and pollution-free, in line with international environmental protection requirements and future product trends. At present, metal container cans are the most convenient to recycle among many packaging materials, and their recycling rate is also the highest.

1. Tin can packaging is easy to open, which can save time in the kitchen.
2. No need for low-temperature refrigeration, it can be stored for a long time at room temperature, which can save considerable electricity.
3. Easy to carry, you can carry a lot of canned food with you.

In short, tinplate has many advantages in packaging. It is a symbol of canning and a good choice for healthy food packaging.
