How to identify the quality of tin boxes

The packaging box chooses to use tinplate box because of its good performance, strong ornamental value, low price and high quality. The root of tin box packaging lies in the design and quality of the packaging. The design affects the attractiveness of the product to consumers, while the quality affects the consumer's satisfaction with the product. The combination of an excellent product and high-quality packaging will definitely get twice the result with half the effort.

Different products need to be packaged, and the process and raw material requirements for tin boxes will also be different. For example, food tin boxes need to be safe and hygienic, moisture-proof and pressure-resistant. The tea tin box needs to be sealed and shading, so as to retain the tea fragrance and storage period to the greatest extent. Seed tin boxes and medicine tin boxes also have strict requirements on packaging boxes.

From the perspective of tinplate materials, it is mainly to check whether the surface of the raw material is flat, whether there are holes on the surface, whether there are scratches, whether the tin plating is sufficient, whether the size is within the tolerance range, and many other aspects. In addition, it is also necessary to check whether the printing meets the required process, whether it meets the color requirements, whether the surface of the printed product is scratched, whether it is neat, whether the paint is peeled off during the stamping process, etc. These are all factors to measure the quality of a tinplate box. Whether the method of production meets the quality standards can only produce high-quality tinplate boxes if every link and every detail is done well.

Moreover, the nutrients contained in the food itself, such as protein and amino acids, will change, resulting in nutrient loss and food damage. In addition to good opacity, the iron box must also have excellent sealing performance to avoid contact with air during transportation or storage, causing the food contained in it to oxidize or enter bacteria to ensure that the nutritional content of the food is excellent. are preserved and will not deteriorate.
