Sometimes customers asked us: What is the process of making the biscuit tin, which one should I choose for my tea tin, cylinder or rectangular? Why there are two dots on the lid, and how to choose the color of the cookie tin, normally all kinds of tin box production process is almost the same, except some special ones like with a handle or with see-through window etc.
Tin box manufacturing process can be divided into two categories: one is the printing process, the other is stamping process, each of them has different details, kindly check as below:
The first is the printing process, can be divided into two categories, one is printing, the other is oiling.
The tinplate printing mainly has offset printing, screen printing, laser printing, jet printing, white printing etc, normally used is offset and screen printing, the laser and Jet Oil for high-grade tin box production.
Oiling usually used on both sides of the tin box coated with light oil, dumb oil and other special transparent oil to protect the printing plate of the text. For Some food-grade iron box, there will be another treatment, the inner surface to be coated with food-grade gold oil, is to prevent food and tin box contact which would cause the pollution.
The second is stamping process. Due to good ductility, the tinplate can be made into various shape tin boxes within the help of molds, like heart-shape tin box, book-shape tin box, etc. It can also be used for 3D carving on the surface to increase outlook design effect.
