First of all, we should understand the differences between the milk powder tinplate steel can and the ordinary food electrolytic tinplate can. Milk powder electrolytic tinplate cans consist of three parts, the lid, the can body and the bottom. The can lid and the can body are welded together by sealing welding, and the pull ring type opening method is adopted. The ordinary food tinplate steel box is mostly withholding type, and the can body lid does not need to be welded, and the cost will be much less. In addition, the can body of the milk powder container is also welded, and the can body is printed with a pattern. In order to avoid damage during printing, an additional process is required. Therefore, the fake of the can body is much more expensive than the ordinary food tinplate steel box. Finally, the milk powder electrolytic tinplate coil can is sealed at the time of production, so the product needs to be loaded from the bottom of the can, so customers need a bottom machine to make the bottom of the can itself. For ordinary food electrolytic tinplate coil cans, the bottom of the can is connected at the time of production. The product is loaded from the top of the lid and the lid can be closed. Therefore, if it is not a special case, the tin can factory will recommend that customers to put protein powder, bone meal, etc. into edible plastic bags, and the outer packaging uses ordinary food tinplate steel cans, which is convenient to use and reduces the cost of production.
