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, custom tin boxes 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. The mainly stamping process includes printing, cutting, stamping, assembly and packaging, etc. Other specific details can be inspected at tin box manufacturers, so that the understanding will be more profound.
The Case for Metal Tin Containers
The first pro for metal tin containers is that they are stylish and original. As touched upon earlier, tin boxes are eye-catching to consumers.
Metal materials have excellent printing performance allowing for brighter and more beautiful designs.
They can even be embossed or debossed, offering a unique tactile feel.
Metal tin containers also come in various sizes and dimensions, allowing for different sealing and treatment methods to make them versatile when considering how to package your product.
The natural strength of metal also helps protect against physical damage too!
And because of this versatility and durability, metal tin containers offer excellent protection against contaminants like moisture, light, and gases.
If you’re selling perishables like coffee or tea, this packaging perfectly preserves the product and helps keep the odor, color, and smell for extended periods.
They are reusable in the fact that they can be recycled and returned to the production cycle without the loss of quality. However, this only makes tin cans a replenishable resource if utilizing proper recycling methods.
The Case Against Metal Tin Containers
This brings us to the cons of using metal tin containers.
Not only are metal tins an exhaustible resource, but many tin containers also end up being discarded instead of recycled and reused.
In addition, the advanced manufacturing needed for metal tin containers is not eco-friendly.
The requirement to mine the ore and smelt the metal causes significant pollution.
Production of metal tin containers is also more expensive than other alternatives.
Add this with the rigidity and heft of metal causes shipping and storage costs to be significantly more costly than lighter-weight alternatives.
Metal is also easily scratched and prone to rusting. Once the container is dented or corroded, the products risk exposure to moisture and air.
