Types of cartons
Folding Cartons
A carton is a type of packaging suitable for food, pharmaceuticals, hardware, and many other types of products. Packaging is the science art and technology of enclosing or protecting products for distribution storage sale and use
Folding cartons are usually combined into a tube at the manufacturer and shipped flat (knocked down) to the packager.
Tray styles have a solid bottom and are often shipped as flat blanks and assembled by the packager. Some also are self-erecting.
High speed equipment is available to set-up, load, and close the cartons.
Egg Carton
Egg cartons or trays are designed to protect whole eggs while in transit. An egg carton is a Carton designed for carrying and transporting whole eggs These cartons have a dimpled form in which each dimple accommodates an individual
Traditionally these have been made of molded pulp. Molded pulp,also named Moulded pulp or Molded Fibre,is a packaging material typically made from 100% recycled Corrugated fiberboard and Newspaper This uses recycled newsprint which is molded into a shape which protects the eggs.
More recently egg cartons have also be made from expanded polystyrene (styrofoam) and PET. Styrofoam is a trademark for polystyrene Thermal insulation, a material manufactured by Dow Chemical Company. Uses PET can be semi-rigid to rigid depending on its thickness and is very lightweight
Aseptic carton
Cartons for liquids can be fabricated from laminates of paperboard, foil, and polyethylene. Most are based on either Tetra Pak or Combibloc systems. Tetra Pak is a multinational Food processing and Packaging company of Swedish origin
One option is to have the printed laminate supplied on a roll. The carton is cut, scorred, and formed at the packager.
A second option is to have the pre-assembled tubes delivered to the packager for completion and filling.
These are suited for aseptic processing and are used for milk, soup, juice, etc. Aseptic processing is the process by which a sterile ( Aseptic) product (typically Food or pharmaceutical is packaged in a sterile container in a way which maintains
Gable top
Gable top cartons are often used for liquid products such as milk, juice, etc. These used polyethylene-coated paperboard and sometimes a foil laminate.
Most are opened by pushing open the gables at the top. Some have fitments to assist in opening and pouring the contents.
Packaging history
An early American packaging industry pioneer was the Kieckhefer Container Company, which was run by John W. Kieckhefer. John W Kieckhefer (1887-1970 was an American businessman He took over Enterprise Box & Lumber Company which was a family-run business started by his grandfather Charles The company excelled in the use of fibre shipping containers, which especially included the paper milk carton. In 1957, through an exchange of stock, the Kieckhefer Conatiner Co. holdings were merged with the Weyerhauser Timber Company of Tacoma, Washington. Weyerhaeuser is one of the largest pulp and paper companies in the world the world's largest private owner of Softwood Timberland
Shape
Although quite often shaped like a cuboid, it is not uncommon to find cartons lacking right angles and straight edges, as in squrounds used for ice cream. In anatomy the Cuboid bone is a bone in the foot See also Hyperrectangle Oblong In Geometry and Trigonometry, a right angle is an angle of 90 degrees corresponding to a quarter turn (that is a quarter of a full circle Squround is a Portmanteau for "square round" ( Cartons, referring to a compromise between a square and a round carton Ice cream or ice-cream (originally iced cream) is a frozen dessert made from Dairy products such as Milk and Cream, combined The number of corners on any given carton is a function of the product it contains. A corner is the place where two Lines of different dimensions meet at an Angle, and a convex corner of intersecting walls is generally thought to be the least beneficial For example, a product with eight vertices would require a box also with eight corners. In Geometry, a vertex (plural "vertices" is a special kind of point.
Tetrahedrons and other shapes are available. A tetrahedron (plural tetrahedra) is a Polyhedron composed of four triangular faces three of which meet at each vertex. Cartons with a hexagonal or octagonal cross sections are sometimes used for specialty items.
Materials
Cartons can be made from many materials: paperboard, various plastics, or a composite. Paperboard is a Paper -like material usually over ten mils (0 Composite materials (or composites for short are engineered Materials made from two or more constituent materials with significantly different physical or chemical Some are "food grade" for direct contact with foods.
Many cartons are made out of a single piece of paperboard. Depending on the need, this paperboard can be waxed or coated with polyethylene to form a moisture barrier. Wax has traditionally referred to a substance that is secreted by Bees ( Beeswax) and used by them in constructing their Polyethylene or polythene ( IUPAC name poly(ethene) is a Thermoplastic commodity heavily used in consumer products (notably the This may serve to contain a liquid product or keep a powder dry.
Artistic design
In art history, the carton (pronounced the French way) was a drawing on ordinary cardboard, used as life-size design for the manufacture in an atelier of a valuable tapestry, such as a gobelin. Tapestry is a form of Textile art. It is woven by hand on a vertical Loom. For information on Gobelin tapestries and carpets see main article Gobelins manufactory Gobelin was the name of a family of During the weaving it hung behind the tapestry in the making, a time-consuming process thus in a creative sense simplified to 'mechanical' painting-by-numbers.
As these were extremely valuable, often commanded by the very richest art-buyers, including princes who hung them in their palaces and even took them on their travels as prestigious displays of wealth, often with a visual message, especially the world-famous Flemish ateliers were deemed worthy to have cartons made by some of the greatest graphic artists of the time, including such celebrated painters as Rubens.
Carton-pierre
Carton-pierre, French for 'stone carton', is a term used for papier mâché decorated to resemble stone, wood, or metal, and used as ornamentation. Papier-mâché ( French for 'chewed-up paper' because of its appearance sometimes called paper-mâché, is a construction material that consists of pieces of
