Aluminium Foil Container
A shaped die cavity-type of container that is formed by combining mechanical and air pressure on a light gauge aluminium foil. (niir)
The process wherein concave (interior bead) or convex (exterior bead) areas are formed spanning the can circumference to provide additional strength and stability to the body. (allstatecan)
Ends that have an easy opening from which the drink will pour out of the can perimeter.
A pre-cut metal sheet that is trimmed/sheared to a specified size will form the body of cans.
The cylinder-shaped portion of a can to which the top and the bottom ends are attached by double seaming. (suretorque)
A roller machine that applies lacquer to coils or sheets.
The process in which a metal is covered with another material/substance for protection against corrosion and to ensure that the metal containers are safe for filling.
a. Machine used for sheet metal fabrication.
A tapered shape lid is generally used on general line cans. It has the general shape of a frustum of a cone. (suretorque)
Crown Cork End
A metal closure is lined with cork or plastic. The cap is crimped around its rim over the finish of a bottle to provide a hermetic seal. (packagingschool)
The process wherein the extreme edge of the end component is turned inward to provide a safe, finished curved edge. The curl forms the cover hook in a double seam. (packaging-labelling)
A closure that is fitted to the can base to withstand internal pressure. (Metal Packaging Manufacturing Association, n.d.)
A joint attaching the top or bottom end of a metal can to its body, formed by interlocking the edges of the end and the flanged body, double folding and rolling firmly together. (packagingschool)
a. The operation of reforming sheet metal without changing its thickness.
Type of container that had undergone drawing and redrawing operations.
Type of container that had undergone drawing and wall ironing operations enabling the cup to have smaller diameter with thin walls while increasing its height.
a. A phenomenon in which the top of a can is slightly wavy or has small ripples called 'ears' due to drawing and ironing processes.
Easy Open End
A can end that is scored on the circumference and fitted with a gripping device (tab) for easy removal of end. (tricorbraun)
The method of checking the integrity of the can's lacquer layer by measuring its conductivity. (fmea)
a. A container where the height is greater than the diameter and may only be formed in aluminium.
The process in which a projecting or flared edge is formed by bending outwards the rims of the can body-cylinder to enable heads and bottoms to be double seamed to the body. (tricorbraun)
These are containers made out of aluminium foil, plastic, or paper materials.
Full Aperture Easy Opening Ends (FAEO)
Ends with a ring pull but when the ring is pulled, the complete end will detach resulting in a full aperture. Commonly used for foodstuff (both human and animals) such as pet food, soup, vegetables, etc.
The empty space in the can that is not filled with product.
A seal that excludes air and will be leakproof at normal temperatures and atmospheric pressures. (tricorbraun)
The operation of thinning the wall of a two-piece can by passing it through-hardened circular dies.
A solvent-based, clear protective layer is applied on metal surfaces for corrosion protection, to limit the interaction between the can itself and the food product, and to avoid discolouration of food product pigments packed inside the can.
These are indentations applied on metal can enhance its resistance against deformation caused by operation processes or by changes in pressure during the shelf life of products. (lup)
a. A method of printing or decorating flat surfaces by means of plates.
a. Sheet metal rolled from slab or ingot that has been wound into coiled roll.
Metal that has been cut from a metal coil, formed by an industrial process into thin, flat pieces, and sheared to form blanks.
The process wherein the can diameter which is initially cylindrical is reduced by bending inwards the upper rim of the can to accommodate the smaller end. (cantechonline)
The process of printing by indirect image transfer, especially by using a metal or paper plate to ink a smooth rubber cylinder that transfers the ink to the paper. (packagingschool)
Peel-off membrane End
A type of closure which has a membrane that seals the content from any external environment. The membrane sometimes sits inside a penny lever-type opening but is more often protected by a plastic cap. These lids are mostly used for milk powder.
Penny Lever Ends
A reclosable cover for the opening of a container such as paint cans and can be opened using a penny as lever.
The operation of reforming a two-piece can into one of smaller diameter and therefore greater height without changing its thickness.
The drawn part from the can end where the tab is attached ensuring end integrity.
These are the conventional/normal type of lids that can be opened with an old fashioned can opener.
The canning operation wherein a hermetic seal is formed by mechanically interlocking the can body to a can end. (wiki)
A plain lid that is stamped from a metal coil and transferred to a conversion press which converts the lid into an easy-open end.
Process of cutting a sheet of metal into narrower strips.
A method for sealing the side seam and other joints of metal cans using a tin-lead alloy. Soldered seams are usually folded or hooked (lock seam), and must be lacquered to prevent corrosion and migration of metals into the product. (packagingschool)
A temperature-induced chemical reaction process that dries or sets inks, coatings or adhesives to increase their ability to withstand corrosion, erosion and degradation.
A container consists of a cylindrical body rolled from a piece of flat metal with a longitudinal seam which is usually formed by welding, together with two can ends that are seamed onto each end of the body.
Chromium-coated steel. Because it is used in food cans just like tin plates, it ironically is classified as a tin mill product.
Thin sheet steel with a very thin coating of metallic tin.
a. A cylindrical container of thin, flexible metal with integral shoulder and neck, with a screw cap closure made of plastic. (tricorbraun)
A container is made from a metal disc that is reformed into a cylinder with an integral end to become a seamless container wherein a loose end is seamed to finally close the can.
The photochemical process instantly dries or sets inks, coatings, or adhesives using high-intensity ultraviolet light.
a. A clear protective coating applied to the metal.
A side seaming method for metal cans wherein the side walls are attached to one another through the use of heat and without using lead. (packagingschool)
