Why many kinds of food cans use tinplate lids
Good mechanical properties: The cover is made of tinplate, which is stronger than other packaging materials, such as plastic, glass, paper, etc., and has good rigidity and is not easy to break. It can be made into the shape and style you want.The iron cover is mainly used to prevent deterioration, and it can be sterilized at high temperature without leakage. If a plastic cover is used, the high temperature will easily deform the cover and cause leakage.
Excellent barrier properties: The tinplate cover has better barrier properties than any other material, with good gas barrier properties, moisture resistance, shading properties, and fragrance retention. In addition, it has reliable sealing and can reliably protect the product.
In addition, many tinplates are now easy to print, and can be printed according to the design that cannot be done, and it is safe to use food-grade ink to print.
Mature technology and high production efficiency: The production history of tinplate cans has a long history, and the technology is mature and has a complete set of production equipment to match it. The production efficiency is high and can meet the packaging needs of various products.
In short, the wide use of tinplate covers is mainly due to the above three advantages of tinplate. I believe that more suppliers will choose tinplate covers in the future.
