Paper Carton
A carton is a box or container usually made of cardboard and often of corrugated cardboard. Many types of cartons are used in packaging. Sometimes a carton is also called a box. Not only do we sell industrial paper boxes such as RSC corrugated boxes and other styles of corrugated boxes, such as fold up mailing boxes and moving boxes, but we also sell cardboard gift boxes, favor boxes, bakery boxes and candy boxes in a myriad of styles, shapes, sizes, and colors.
Types of cartons: 
Folding cartons
Typical blank for folding carton
A carton is a type of packaging suitable for food, pharmaceuticals, hardware, and many other types of products. 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. Traditionally these have been made of molded pulp. This uses recycled newsprint which is molded into a shape which protects the eggs. Premium molded paper pulp egg cartons are a 92% reduction in waste after use compared to plastic[citation needed] More recently egg cartons have also been made from expanded polystyrene (similar to styrofoam) and PET.
Aseptic carton

Cartons for liquids can be fabricated from laminates of liquid packaging board, foil, and polyethylene. Most are based on either Tetra Pakor SIG Combibloc systems. One option is to have the printed laminate supplied on a roll. The carton is cut, scored, 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 and are used for milk, soup, juice, etc.
Gable top carton of cream
Gable top cartons are often used for liquid products such as milk, juice, etc. These used polyethylene-coated liquid packaging board and sometimes a foil laminate. Most are opened by pushing open the gables at the top back and pulling the top (spout) out. Some have fitments to assist in opening and pouring the contents.
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 polyethyleneto form a moisture barrier. This may serve to contain a liquid product or keep a powder dry.
