Baosteel's tin mill products are widely used for packages of a
wide variety of foods such as deep processed fruits,
vegetables, meat, seafood, and mixed congee. Steel plates used
for food cans range from T-2.5 to DR-9, covering both single
reduced and double reduced plates to meet different needs of
different users. When selecting appropriate steel for food
cans, one needs to consider factors such as properties of
container contents, user's application conditions and coating
requirements.
Spray Cans
Mainly used for packaging household chemicals, such as air
fresheners, personal care products, and pesticides, spray cans
are made mostly of tinplates. The steel produced by Baosteel
for spray cans is featured by high elongation, excellent
deep-drawing performance, good plate shape, and good surface
quality and is used by many famous can manufacturers.
Baosteel's steel for spray cans is available in a wide range,
including both BA and CA plates. CA plates are further divided
into SR and DR plates to meet different order needs of
different users.
Beverage cans
The most important application of Baosteel's tin mill products
is to be used as steel for manufacturing beverage cans.
Currently, Baosteel's tin mill products have been used to
manufacture packages of tea drinks, protein drinks, energy
drinks, juice and coffee drinks. Baoshan's steel for beverage
cans is featured by excellent machinability, good hardness
stability and good rounding performance, suitable for
different a wide variety of users.
DI Cans
DI cans refer to drawn and ironed two-piece cans, which are
mainly used for packaging beer and carbonated beverages. As DI
cans are highly deformable, the tensile property of tinplates
needs to be good. Currently, Baosteel is the only Chinese
manufacturer that can produce steel for DI cans. Baosteel's
steel for DI cans is featured by good tensile property and
easy machinability and is widely used for packaging of
products such as Coca-Cola, Qingdao Beer, and Yanjing Beer.
DRD Cans
DRD cans refer to drawn and redrawn cans and have extremely
strict requirements on mechanical properties of raw materials,
especially anisotropy. For example, if the anisotropy of a
tinplate sheet is too big, defects such as obvious earing and
insufficient trimming may occur and cause rejected cans. To
address the abovementioned issues, Baosteel has conducted
specific research to improve its steel for DRD cans to meet
different application needs of different users.
Twist-off Caps
Baosteel's steel for twist-off caps is widely used for
manufacturing twist-off caps of a wide variety of food cans.
Currently, the minimum thickness of Baosteel's steel for
twist-off caps is 0.16mm, and Baosteel will continue to
conduct further tests to reduce thickness in the future.
Baosteel's steel for twist-off caps is featured by stable
hardness, good plate shape and low earing rate, able to meet
different application requirements of different users.
Easy Open Ends
The EOE manufacturing process can be divided into two stages.
First, make the base end. Then, connect the base end and the
ring to form the easy open end. The manufacturing process of
easy open ends is more complicated than that of ordinary ends
and has high requirements on strip steel. Baosteel's steel for
easy open cans is featured by good machinability and excellent
post-coating adhesion, suitable for a wide variety of
complicated machining processes.
Chemical Cans
Another important application of Baosteel tinplates is to make
chemical cans. Baosteel tinplates for chemical cans are
featured by excellent machinability and good plate shape,
widely applicable for packages of chemical products.
Milk Powder Cans
Tinplates used for manufacturing milk power cans are required
to have excellent surfaces that are clean and free of smudges.
Baosteel has gained rich experience in manufacturing tinplates
for milk powder cans, and its products have been supplied in
large quantities to downstream users. Its tinplates for milk
powder cans are available in a wide range of specifications,
able to meet different needs of different users.
Crown Caps
The crown cap gets its name from its shape which is like a
crown. Crown caps are mainly used as closures for beer bottles
and have high requirements on dimensions, hardness and
formability of steel. Some crown caps even have requirements
on bending resistance. Currently, Baosteel can supply
tinplates for crown caps with or without bending resistance
and meet different needs of different users.
Battery Cases
Baosteel's tin mill products, including T-2.5BA and T-3BA, are
mainly supplied to corporate users for manufacturing battery
cases, such as CPMC, NAMPAK, Fujian Xiangda. Baosteel's
tinplates for battery cases are available in a wide range and
of good performance, able to meet the needs of different
users.
Electric Rice Cooker
Baosteel's tin mill products, including T-4CA, T-3CA and
T-2.5CA, are mainly used for manufacturing electric rice
cookers. According to the classification of forms, finished
products are divided into steel coils and steel plates for
electric rice cookers. Steel plates for electric rice cookers
require excellent surface quality, which needs to be strictly
controlled during production. Currently, Baosteel's steel for
electric rice cookers is mainly supplied to COFCO for
manufacturing electric rice cooker panels.
Thickness Reduction for Crown Caps
With the increasingly intense competition in the metal closure
and end market, cost reduction and efficiency increase have
become a must for all cap manufacturers. Traditionally, SR
tinplates are used
Compared with SR tinplates, DR tinplates have better hardness,
higher yield strength and smaller thickness, thus suitable for
meeting users' goal for thickness decrease and cost reduction.
Founded in December, 1993, Company A is a joint venture
specialized in manufacturing three-piece metal cans with more
than 300 employees and an annual turnover of RMB 200 million.
