Liquid tinplate containers have a filling aperture in the flat top of the container. The tinplate containers are suitable for liquid filling products with a low viscosity such as solvents, thinners, wood-stains and cleaning products. In addition to this, liquid tinplate packaging is perfectly suited for safe transport and storage of hazardous materials and often has a UN certificate. Liquid tinplate packaging is available in a round and a rectangular design (see our brochure for rectangular liquid tinplate containers for more information). All round liquid tinplate packaging is of a cylindrical shape, meaning that the body is straight and does not taper inwards. Internally coated liquid containers are not common but are available.
Specifications
The diameter is the most important determining factor for round liquid tinplate packaging. We have various measurements for a number of capacities, tailored to the requirements of the local market. We indicate the options in the overview below. Besides the standard capacities, many other sizes are available. We refer you to our website for the exact measurements.

Assortment
We have a wide range of round liquid containers. Various measures are usually available per capacity. The aperture can vary in diameter. The combination of aperture and the type of cap partially determine the UN certification. Round liquid tinplate packaging is available from 100 ml up to 28 litres. The liquid containers from 2,5 litres, are fitted with a wire handle (plastic or metal) in order to make pouring and carrying easier. In various sizes, the bottom is 'necked in', which allows the product to be stacked.
The diameter in combination with the height determines the capacity. The most standard ground sizes are included in the table. Round liquid tinplate packaging are available with UN certification from 250 ml. Round liquid tinplate packaging is most commonly used in the smaller sizes, up to 1 litre, depending on the user market. In the larger sizes, one often prefers the rectangular shape over the round shape because of the possiblity of the more efficient stacking. The round shape becomes more interesting again in the sizes over 20 litres, because of the greater level of robustness that is created by the shape and the thickness of the tinplate.
Screw top and closures
There are in fact two types of closings – a plastic cap and a metal cap. Plastic caps are available in many varieties and several colours. The caps can be fully made out of plastic, or can be manufactured in combination with an aluminium seal. The aperture can be DIN or REL. The difference in REL is that the hole is bent outwards which creates an 'upright collar'. This type of screw top was developed to make it easier to empty the container (the screw top protrudes after all). Currently REL is the most common filling aperture.
Plastic caps can be either extractable (bellow seals) or a screw top type. Bellow seals disappear inside the container and are pulled out and fitted with a pouring tout. These tops improve the stackability of the liquid containers. Screw tops are often combined with a Child Safety Certificate and are frequently used in consumer markets. Because the screw tops stick out of the flat top, stacking on a pallet is not convenient.
All types of plastic caps can be used to reclose a product after opening. Plastic caps can easily be applied by hand. When filling at high speed and in large numbers of units, the plastic caps are sometimes applied by machine. We have developed a special cap pusher for medium-large charges in order to improve effectiveness.
Metal screw top
Metal screw tops are in particular commonly used for aggressive filling products which are not suitable for closing with plastic caps. The metal screw top is also often used in laboratory settings. The caps are easy to process by hand and are easy to reclose. The round liquid tinplate liquid packaging can also be supplied with a flat metal screw cap in the sizes from 15 litres upwards (Tri-Sure® closing).
Markets
Round tinplate packaging is most commonly used to pack Car Refinish products, solvents, wood protection products, solubles and liquid chemical products. We have created a packaging line with the Hildering 2 Component Locking Ring in which round liquid tinplate packaging has an important role as B-component packaging. You can find more information in our Hildering 2-Component Intermediate Locking Rings brochure. When a product has to be coloured, this type of tinplate packaging is less suitable than the tinplate packaging with a removable lid because of the small aperture.
Printing
The round liquid tinplate packaging can be labelled quite quickly and easily because the shape of the body is cylindrical and there is no handle. By far the most tin containers are printed by offset printing. In larger quantities, offset printing is an excellent solution to allow for optimal communication. The numbers at which this becomes an option are available upon request. Smaller quantities (from 2 pallets) can be printed using digital printing technology. Digital printing of round liquid tinplate containers is currently only available for the 500 ml and 1 litre sizes. You can find more information in our brochure about the Hildering Colour Can.
Protecting outside
When filling products are stored and processed in a damp environment, an extra layer of lacquer on the outside of the tinplate packaging is recommended. We can apply a transparent or gold lacquer to the vulnerable parts (bottom and top), so any oxidation can be prevented.
