Main Application Areas Of Tinplate

With the continuous improvement and improvement of sheet printing and processing technology, the application of sheet packaging is becoming increasingly widespread. The demand for tinplate packaging industry is constantly expanding, putting forward higher requirements for both quantity and quality of tinplate packaging. This has ushered in a new period of growth opportunities for tinplate packaging, and the sustained and rapid development of various industries has brought broad market development space to the tinplate packaging industry. What are the main application areas of tinplate?
1. Cosmetic packaging: The interior of the cosmetic tin box is often coated with harmless coatings made of epoxy resin, phenolic resin, and other raw materials, which do not pollute the cosmetics and are harmless to the human body. It also has good corrosion resistance and can prevent the deterioration of oils and media in the cosmetics, effectively protecting the quality of the cosmetics from deformation, and has shock resistance, fire resistance, and high temperature resistance.
2. Tea packaging box: Tea is made by frying and drying the buds and leaves of the tea tree. Once damp, it will undergo qualitative changes, and the aroma of the tea itself is also easily volatile. There are many requirements for environmental factors such as moisture, temperature and humidity, light, oxygen, etc. Therefore, the containers and methods used for storage are more particular. The tin can meets these requirements., The iron can packaging has relatively strong sealing performance, and the can body is also relatively thick. It has good insulation and preservation functions, completely isolating the influence of environmental factors. It will avoid color changes in food due to light, oxygen, and moisture, and will not fade due to aroma overflow or be contaminated by environmental odors. Therefore, the stability of tea storage is better than other packaging materials.
3. Food packaging: Canned food is beneficial to the human body. For canned food, except for a few light colored fruits and fruit juice cans, most use internally painted empty cans to improve the corrosion resistance of the container. Due to the electrochemical action of metals, a small amount of iron is released during storage in canned food coated with paint. It exists in the form of divalent iron in sealed canned food and is easily absorbed by the human body, with a content of approximately 1 to 9 ppm. Due to these properties, the tin can provides a closed system that completely isolates environmental factors, apart from heat. It prevents discoloration of food due to light, oxygen, and moisture, and does not fade due to aroma penetration or become contaminated by environmental odors. The stability of food storage is superior to other packaging materials, and vitamin C has the highest preservation rate and the best nutrient retention.
In addition, it has another advantage, which is that the environmentally friendly tin cans can be recycled, meet international environmental requirements, and conform to future product packaging trends. Iron boxes are safer than paper packaging.
