Are there any friends curious about the production process of tin boxes? Usually, the tin packaging is made of tinplate material, through the printing process to print the exquisite artworks; cutting the tinplate into the specified specifications; then stamping by punching machines, and finally assembling and packaging. Today let’s learn about the production process of the tin box!

1. Prepare tinplate: Generally, the main material of the tin box is tinplate. After the customer confirms the order, the most suitable tinplatewill be orderedbased on variety, size, thickness, and so on. The tinplate is usually stored directly in the printing factory. On the identification of the tinplate quality, it can usually be visually measured to see whether the surface is scratched or not, whether there are rust points, the thickness can be measured by the equal micrometer, and the hardness can be felt by hand.
2. Printing: the confirmed design and layout drawings are given to the printing factory, and then the printing factory will arrange the tinplate printing, usually a sample will be providedto the printing factory to check the colors. In the process of printing, we should pay attentionthat whether the printing color matches the sample, whether the setting is accurate, whether there are stains, whether there are scars, and so on. These problems are generally responsible for the printing factory.
3. Cutting material: After the tinplate printing, we need to cut the material with the cutting machine according to the cutline.
4. Punching: It is the most important job of making a tin on the punching machine. Generally, tin must be divided into many processes to complete. The punching processwillusually bring the largest damage to the product. So the engineer and QC will check the tin box quality every half an hour on the production line. To make sure the mold and machine condition is as good as the beginning to avoid quality problems.
5. Packaging: After the production is finished, the packaging department is responsible for cleaning and assembling. All tins will go through the oven and be cleaned by a cleanroom. In order to make sure all tin boxes arrivedin good condition, we will put each tin into a PP bag, then into a master carton. Each layer is separated by dividing cards, and wooden pallets if needed.

The most common protection oil for iron boxes is Gloss varnish, UV and Matte varnish.

Glossy varnish: The color preservation performance is good, which can improve the brightness of the printing color, the color is full and shiny and consistent with the traditional aesthetic of consumers.

Matte varnish: Contrary to the effect of gloss varnish, it has no gloss on the surface of the tinplate, a paper texture, classic and elegant decorative effect.

UV: Spot matte/Spot glossy, the effect of gloss varnish and matte varnish are combined. After printing gloss varnish on the tin plate, partial print matte varnish. the shiny is different, which can highlight the information that you want to be transmitted. The process is more complicated.

As one of the modern packaging products, tin packaging has the characteristics of sustainable development, innovation and environmental protection friendly. It can quickly integrate into the development trend of the new packaging market.

The customization of tin packaging can affect the company’s image and brand promotion and increase consumers’ interest in the product. Printing ink with special effects can help you stand out from competitors and emphasize the brand’s personality.
