Metal Can Packaging: The Ultimate FAQ Guide
This article will assist you in selecting highly effective and dependable metal can packaging for your business.
As a result, before importing metal can packing from China, be sure to read this guide.
Let’s get started.
What Is Metal Can Packaging?
These metals have good barrier characteristics and are commonly utilized in food packaging. They are used as packaging and closures for glass bottles and composite cans.
Metal Can Packaging
What is the Definition of a Metal Can?
A steel can, tin can, tin, steel packing, or can is a container constructed of thin metal used to distribute or store commodities.
You must open numerous cans by cutting the “end” open; others have detachable lids.
They are capable of storing a wide variety of materials, including food, beverages, oil, and chemicals.
How Do Metal Packaging Form?
Three Piece Cans
There are two end lids and a body that make up the three-piece structure.
It is a cylindrical construction made of rolled flat metal sheets with an open top and bottom.
They can be formed in any combination of height and diameter, allowing for mixed requirement cans.
It has pre-coated, printed, and rolled metal sheets that are bonded longitudinally by soldering or welding.
Moreover, soldering food cans is usually avoided due to worries about lead migration from tin/lead solder into foods.
In the food industry, welding is chosen over soldering since overlapping is required for welding and uses less metal than interlocking for soldering.
Following side seaming, beverage cans are necked and flanged, while food cans are beaded and flanged.
In order to reduce metal usage, necking usually involves decreasing the diameter of flat ends in an entirely cylindrical seamed body.
Beading provides food cans with spherically curved corrugations for increased strength during retorting.
Flanging is the process of producing outward flanges or hooks on the outside of can lids in order to improve their fit.
Both the flange and the lid edge are engaged mechanically to secure the can ends or lids.
Two-piece cans had one end or lid, and a seamless body with a flat metal sheet bent to form cylindrical cup-type construction with a closed bottom and no joints.
It is cheaper, cleaner, and has a larger printing area than three-piece cans due to the lack of a side seam.
It also lacks a side seam which makes two-piece cans lighter and more durable.
In order to produce two-piece cans, two basic processes are used, reducing the wall thickness and increases such as drawn and wall ironed (DWI) and redrawn (DRD).
Drawn and Wall Ironed (DWI)
It is necessary to stamp circular discs from greased metal sheets during the process of manufacturing.
It has a forming procedure punch that pulls a round disc to shallow cup uniform wall thickness.
Ironing is a method of reducing wall thickness and increasing body height by passing shallow cups through tungsten carbide dies.
The built-up structure is later leveled and cleaned to remove lubricants.
Finally, the bottom is domed or contoured, and like three-piece cans, it is flanged.
The base thickness is greater than the wall thickness because only the side walls are stretched and flattened during ironing.
Drawn and Redrawn (DRD)
DRD cans start like DWI cans, with stamping and shaping.
It replaces the ironing stage of DWI cans with consecutive stretching of the can’s original structure like shallow cups.
Multistage drawing allows the metal to flow from base to wall of containers, ensuring adequate wall and base thickness for DRD cans.
Like DWI cans, DRD cans need to be cleaned and flanged.
Aluminum Collapsible Tubes
Collapsible tubes are flexible, lightweight, tamper-proof, and hygienic food containers with multi-use options.
It is manufactured by extruding an aluminum slug with the help of a plunger. After that, it might be enameled or printed to improve its appearance.
End sealing is accomplished by folding and heat sealing after simply applying latex or lacquer.
Aluminized collapsible tubes were commonly used in the food business for cheese spreads and jams, and jellies.
With the advent of inexpensive plastic laminates, their use in food has decreased significantly.
This aluminum tube has an outer diameter of 12.7–57 mm, a wall thickness of 0.10–0.18 mm, and a shoulder angle of 30°.
Drums are industrial packaging materials used for bulk transportation and storage of processed or semi-processed food items.
Drums are big containers holding 100–250 L, whereas ‘pails’ hold 5–25 L.
There are three parts to a drum such as the body, the top and bottom lids, and the fittings.
Drums are made by shearing metal sheets, grinding to reduce sharp edges and body forming.
It has spot and seam welding for attaching overlapped structures, corrugating procedures.
It assembles symmetrical corrugations and flanges for lid/drum co-joining. A single sheet should be used to manufacture the steel drum’s body.
Convenient handles should be supplied on drums up to 25L size. In the presence of 40 kPa pressure, liquids in drums should not leak.
Chemicals, powders, and highly corrosive compounds are commonly stored in metal drums.
These aluminum beverage bottles, often known as bottle cans, are used for storing beverages.
Previously, bottle cans were created by impact extrusion, but today the coil-to-can process makes them fast and cheap.
A spindle extrudes an aluminum slug encased in a die cylinder, producing a flawless can of very small diameters.
These aluminum bottles are mostly utilized for beer and aerosols.
It is a bottle can with an easy-open cap that reduces the wall thickness and weight while keeping essential qualities.
Metal Caps and Closures
Metal Caps and Closures
Metals are also utilized to seal drinking glass bottles as pilfer-proof caps.
The crown cap is commonly composed of 0.25 mm tinplate, tin-free steel, or black plate.
In addition to protection and design, the crown hat should be devoid of pit holes and odors.
You should use a hot-melt type of glue to coat the interior surface of the crown cap with cork or plastisol liner to prevent the crown cap from falling out.
Metal closures widely used in canning include twist-off, press-twist, pry-off, and deep-press.
The tin plate seals that come with the metal containers must be unscrewed or pulled off in order to open them.
Glass jar and bottle lids are generally composed of 20–70 micron aluminum foil coated with polyacrylic or polyvinyl chloride.
Baby meals, jams, pickles, and dry powders all use vacuum closures such as lug caps and twist-offs.
In order to prevent tampering with milk bottles, aluminum foil is utilized as a tagger or tamper-proof diaphragm for containers.
How is Metal Manufactured?
Thus, producing huge quantities of metal such as iron, aluminum, or copper entails two independent processes.
Its process of removing a section of a mine or quarry from its existing condition.
They were then refining the ore to separate the metals from their oxides to obtain the pure form required.
What Does the term “Metal Cans” mean?
Metal cans refer to empty, clean metal containers composed of aluminum, tin-plated steel, or zinc-plated steel.
Routinely used to package food, beverages, or other products, and are free of food, beverage, or other contamination, as specified by the agency in its rules and regulations.
Is Metal Suitable for Can Packaging?
It is suitable because metal-based packaging materials have excellent barrier properties.
They are frequently used in food packaging.
They are used in a variety of packaging formats and as closures on a variety of containers, such as glass bottles and composite cans.
What Is Material Used to Make Cans?
While the majority of food cans are made of steel, beverage cans are often made of aluminum.
Chromium and nickel can leach from steel; however, the levels are minute to non-existent.
Can Tin Cans be Recycled?
Each and every metal can is indefinitely recyclable.
It makes no difference whether they are aluminum beverage cans or food cans made of tin, steel, or bi-metal.
Place them in the recycle container.
What is the Manufacturing Process for Metal Cans?
The metal sheet is pressed into circular shapes.
These fragments are shaped into cups.
The process continues as a can is manufactured.
The cans must be cleaned, dried, varnished, and printed.
Are Metal Can Packagings Superior to Plastic Can Packagings?
According to the Environmental Protection Agency, aluminum cans contain around 68 percent recycled material.
In comparison, only 3% of plastic bottles are recycled.
As a result, aluminum is often regarded as the more environmentally friendly material.
Is it Possible to Recycle Cans?
Numerous food and beverage goods that we purchase are packaged in cans.
It is constructed of either aluminum or steel.
Both of these materials are recyclable once we’ve used them up and can be used to produce new cans or other products.
How is the Material Recycled?
Typically, cans are collected and sent to a recycling facility, where they are cleaned, sorted, and crushed.
The aluminum cans are then melted in a furnace set to 660 degrees Celsius.
Pour the molten metal into a mold, where it will harden.
Recycling aluminum is far less expensive than mining it.
What is the Purpose of Recycling Metal?
Because metals may be melted and reformed indefinitely, scrap metal is an infinite resource.
By recycling metal, you may help minimize pollution, conserve resources, and prevent the garbage from being disposed of in landfills.
And to avert habitat degradation as a result of additional ore extraction.
What May Recycled Metal Be Used For?
- Pots and pans for cooking
- Electrical conductor
- Frames for spectacles
- Farm machinery
- Containers for food and beverages
- Steel framing for structural steel buildings
How can Cans be Repurposed?

What Advantages Do Metals Offer?
Resistance to Heat
Metals have a more excellent melting point and are therefore less prone to deteriorate at elevated temperatures.
Metal grades are often stronger, more robust, and more resistant to corrosion than their plastic counterparts.
Metal fabrication techniques include casting, deep drawing, welding, forging, soldering, and chipping.
Metal is typically the most cost-effective material, especially for high-volume or long-term production runs.
What Effect Do Tin Cans Have on the Environment?
Aluminum cans may result in less ocean waste, but they come with their own environmental cost.
Each can contribute roughly twice as much carbon to the climate as a plastic bottle.
Are Metal Can Environmentally friendly?
Aluminum cans are the most environmentally friendly beverage packaging option on practically every metric.
Aluminum cans have a better recycling rate and contain a greater percentage of recycled material than other package types.
They are compact, stackable, and robust, which enables brands to package and transport more beverages while using less material.
What Materials Used for Metal Can Package?
These metal can packagings used different materials such as coated steel, tin plate, tin-free steel (TFS), polymer-coated steel, stainless steel, and aluminum.
Why is Metal an Excellent Material for Packaging?
Metal packaging is resistant to knocks and blows and can sustain severe temperatures and pressures.
They ensure the highest level of safety for food and other delicate products.
In a 1m3 space, up to 10,000 tins of canned goods can be stacked.
Is Metal Packaging Environmentally Friendly?
Metal packaging is recycled at a higher rate than any other type of primary packaging.
Steel is the most recyclable material in packaging.
Currently, 79.5 percent of steel packaging is recycled.
Over two decades of constant progress in the steel for packaging business has resulted in a more than threefold increase in recycling rates.
How Do You Determine the Identity of a Tin?
If you suspect your metal is aluminum, repeat the magnet test.
Aluminum and tin are interchangeable, yet tin adheres to a magnet while aluminum does not.
Tin is similar to aluminum in color but has a somewhat duller surface.
