What are the specifications for food tin boxes?

 Standards and Requirements for Customizing Food Tin Boxes

Tin boxes are widely used in our lives, and when food tin box manufacturers customize food tin boxes, there are several standard requirements that must be met. Food tin boxes are made from tin-coated thin steel plates and are formed into food packaging boxes through processes such as welding, stamping, or bone fastening. They are used to package and protect food. When manufacturers complete the production of food tin boxes, they must test the finished boxes to ensure they meet the relevant standards. The common standards mainly include the following four aspects:

 a. Key Areas Standards:

These standards pertain to the positioning of the main patterns, text, tin box logos, and barcodes on the food tin box. However, checking if the finished food tin box meets these standards is not sufficient. It is also necessary to inspect the box's airtightness, leakage caused by pinholes, the accuracy and completeness of the printing, and the uniformity of the welding, among other aspects.

 b. Front View Standards:

The front view standards involve placing the tin box's graphic side directly behind or below the sunlight, representing the outer surface of the food tin box that can be observed.

 c. Scratch Standards:

The scratch standards specify that the printing surface of the food tin box should not have scratches larger than 0.3mm × 20mm, and there should be no visible iron scratch marks.

 d. Non-Front View Standards:

These standards apply to the surfaces of the tin box other than the front view, such as the back, sides, bottom, and inner surfaces.

Customizing food tin boxes primarily involves adhering to the standards for the front view, non-front view, key areas, and scratch-free surfaces. By ensuring compliance with these standards, manufacturers can produce high-quality food tin boxes that effectively protect and present the packaged food.
