Among all kinds of metal packaging materials, tinplate is the most widely used and highly discussed one.
From the familiar biscuit tins, coffee cans, tea cans, milk powder cans, to exquisite gift boxes, badges, cultural and creative storage boxes, most of them are made of the same material: tinplate.
This article will start from ” what is tinplate “, ” tinplate material characteristics and origin “, ” tinplate advantages and disadvantages “, and extends to the actual application of tinplate cans, tinplate boxes, tinplate badges and other finished products, to help you once grasp this metal packaging industry’s key materials.
What is tinplate? How do you say “tinplate” in English and Japanese?
Tinplate
Tinplate Japanese: Buriki
Tinplate, formally known as tin-plated steel sheet, is a metal material made by plating a layer of tin on both sides of a cold-rolled low-carbon thin steel sheet.
The structure generally consists of:
- Steel Substrates (Low Carbon Steel)
- Tin-iron alloy layer
- Tin Layer (Sn)
- surface oxide film
- Protect oil film
Such a structure allows the tinplate to be both:
- Strength and rigidity of steel
- Tin’s rustproof, corrosion-resistant and odorless properties.
- Excellent printability and molding processability
Therefore, it is especially suitable for all kinds of metal packaging materials, including food cans, chemical cans, pharmaceutical packaging, cultural and creative gift boxes, and so on.
The origin of the name “Macouchetti”: Is it related to Macau?
Many people think that ” tinplate ” is the name of a certain kind of real estate, but it is actually related to history.
- In the mid-Qing Dynasty, China began to import tin-plated steel sheets (foreign iron) from Macao.
- At that time, “Macau” was anglicized as “horse mouth.”
- This tinned steel imported from the “horse’s mouth” is therefore called “tinplate”.
Tinplate = tinned steel sheet from “Macau” → the name is still used today.
The official scientific name is “Tinplate”, but in the Chinese industry, “tinplate” has become the default name.
Third, tinplate material properties: why so many packages choose it?
1. Rust and corrosion resistant
The surface of the steel plate is coated with a layer of high purity tin (usually > 99.75% pure), which is an effective barrier to air, moisture and contents, minimizing the chance of rust and corrosion of the steel plate.
2. non-toxic, odorless (food grade)
It meets the standard of food grade tinplate, the tin layer itself is non-toxic, odorless, and with the internal coating process, it can pass the food contact material related tests, and is the material for cans, biscuit cans and tea cans.
Answer to “Is tinplate toxic?
Generally speaking, food-grade tin plates used for food packaging are considered safe and non-toxic under proper conditions of use:
- Is it from a qualified tinplate manufacturer
- Availability of qualified internal coatings and processes
- Compliance with local food container regulations
3. Good opacity and light barrier
The metal itself is impervious to light, which prevents oxidization and deterioration of food products caused by light, which is especially important for tea, coffee, health products and powdered food.
4. mechanical strength, impact resistance, good stacking
Tinplate is made of steel, which is strong and not easy to be deformed by extrusion, and is safer and more reliable for transportation and stacking storage than glass and plastic.
5. Good printability and texture.
The surface can be directly color printed, varnished, matte, partial light and other effects, finished products such as tinplate boxes, tinplate cans, tinplate badges are very suitable for branding design, the overall texture is better than the paper box and general plastic packaging.
6. Recyclable and environmentally friendly
Tinplate is a 100% recyclable metal and can be recycled after recovery, which is in line with the current global trend of recycling economy and environmental protection packaging.
Four, tinplate advantages and disadvantages of the organization (once to see and understand)
Advantages of Tinplate
- Rust and corrosion resistant: Tin layer and protective film can effectively delay rusting.
- Excellent moisture-proof sealing: with metal cap or roll seal, it can completely isolate air and moisture.
- Good light-blocking effect: suitable for food, health care products and special chemicals that are afraid of light.
- High strength, drop and pressure resistance: suitable for export transportation and long term stacking.
- High-quality appearance: suitable for gift boxes, co-branding, limited brand packaging
- Easy to print and process: Various shapes and print designs can be created.
- Good recyclability: environmentally friendly metal packaging material
Tinplate defects
- Higher cost: Higher unit price and molding cost compared to paper box and some plastic packaging.
- Heavier than Aluminum: Compared to aluminum and plastic cans, the weight is heavier and the transportation cost is slightly higher.
- The plating layer is afraid of scratches: If the tin layer scratches and exposes the steel, it will be easy to rust under the impact of high humidity environment.
- High cost of customized shape: special shape tinplate box, tinplate cans need to open mold, small amount of production does not have the cost advantage.
Therefore, in practice, most customers will use tinplate:
- Need texture + brand image packaging
- Products that require long term storage, light barrier, and moisture barrier.
- Gift boxes, co-branded limited editions, and appearance-conscious product lines.
Tinplate production method: hot-dip tinning vs electroplated tinning
Hot-dip tinned steel plate
By immersing the steel plate in molten tin, the overall coating is thicker and has better anti-corrosion properties, which is common for some special applications.
Electroplated tinplate (today’s mainstream)
The use of electroplating, precise control of the thickness of the tin layer, the surface is fine, suitable for high-precision printing and thin plate applications, is currently the mainstream material for food packaging, tinplate cans, tinplate boxes.
The difference between tinplate and stainless steel: how to choose?
| Project | Tinplate | Stainless Steel |
|---|---|---|
| Structure | Tin Plating on Steel Plate Surface | Contains chromium, nickel and other alloying elements |
| Rust prevention | Dependent on tin and coating | High corrosion resistance |
| (manufacturing, production etc) costs | Relatively low | Relatively high |
| formability | Good ductility, suitable for sheet and roll sealing cans. | Harder, no rules for deep-drawing and molding, high cost |
| Applications | Cans, tin cans, gift boxes, tinplate badges | Kitchenware, Medical Equipment, Building Materials, Heavy Industry |
| outlook | Color printing and high degree of design freedom | Good texture of original metal color, but printing is more limited. |
- For fine printing, branded appearance, moisture-proof sealing and cost → Mostly tinplate.
- Acid, alkali, high temperature, high pressure, mechanical structure → Stainless steel is preferred.
