A carton is a type of [[packaging]] typically made from paperboard that is suitable for food, pharmaceuticals, hardware, and many other types of products.<ref name=":0">{{Cite web|url=https://refinepackaging.com/blog/carton-boxes/|title=Guide to Carton Boxes and Packaging|website=Refine Packaging|date=10 November 2020 |access-date=16 December 2022|archive-date=3 February 2022|archive-url=https://web.archive.org/web/20220203033716/https://refinepackaging.com/blog/carton-boxes/|url-status=live}}</ref> [[Folding carton]]s 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 carton]]s 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. More recently, egg cartons have also been made from [[expanded polystyrene]] and [[Polyethylene terephthalate|PET]].

===Aseptic carton===
Cartons for liquids can be fabricated from laminates of [[liquid packaging board]], foil, and polyethylene. Most are based on either [[Tetra Pak]] or [[Schweizerische Industrie Gesellschaft#Packaging|SIG Combibloc]] systems.{{Citation needed|date=August 2020}} 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 packaging plant for completion and filling. These are suited for [[aseptic processing]] and are used for milk, soup, juice, etc. Paperboard-based cartons are lighter compared to a similarly sized steel can, but are harder to recycle.  Some open-loop recycling operations pelletize or flatten ground-up cartons for use in building materials; closed-loop recycling is possible by separating the layers before processing, though some recyclers only recycle the cardboard fibers.<ref name="npr">{{Cite news|title=In The Recycling World, Why Are Some Cartons Such A Problem?|url=https://www.npr.org/sections/thesalt/2018/03/09/591568093/in-the-recycling-world-why-are-some-cartons-such-a-problem|access-date=27 September 2019|publisher=NPR|date=9 March 2018|last1=Jacewicz|first1=Natalie|archive-date=22 September 2019|archive-url=https://web.archive.org/web/20190922184836/https://www.npr.org/sections/thesalt/2018/03/09/591568093/in-the-recycling-world-why-are-some-cartons-such-a-problem|url-status=live}}</ref>

=== Perga carton ===
Perga cartons entered production in 1932 as a [https://www.ift.org/news-and-publications/food-technology-magazine/issues/2002/july/features/the-paper-beverage-carton-past-and-future leak-proof can] during World War I. Jagenberg Werke AG, in Düsseldorf, Germany, patented the design. The carton had a ribbed texture and paper sleeves covered in paraffin material, which provided a seamed structure from base to lid. Most cartons had a capacity of 200 mL. Development of the carton slowed during World War II, but the design would see a revival within European markets in the 1960s.

===Gable top===

Gable top cartons are often used for liquid products such as milk, juice, etc. These use [[polyethylene]]-coated paperboard<ref>{{Cite web|url=https://www.recyclecartons.ca/carton-recycling/|title=Carton Recycling|website=Carton Council|access-date=8 August 2021|archive-date=9 August 2021|archive-url=https://web.archive.org/web/20210809123912/https://www.recyclecartons.ca/carton-recycling/|url-status=live}}</ref><!-- Contrary to what some may think, cartons are not wax coated. What you may see as wax on a carton is actually a thin layer of polyethylene (plastic).  --> or other [[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 eating the contents.<ref>{{Cite web|url=https://www.elopak.com/usa/about/history/|title=A consumer favourite for more than a century|website=Elopak|access-date=6 May 2021|archive-date=6 May 2021|archive-url=https://web.archive.org/web/20210506095118/https://www.elopak.com/usa/about/history/|url-status=live}}</ref><ref name="auto1">{{Cite web|url=https://ohiohistorycentral.org/w/Folded_Paper_Milk_Carton|title=Folded Paper Milk Carton – Ohio History Central|website=ohiohistorycentral.org|access-date=8 August 2021|archive-date=8 August 2021|archive-url=https://web.archive.org/web/20210808082547/https://ohiohistorycentral.org/w/Folded_Paper_Milk_Carton|url-status=live}}</ref><ref>{{Cite web|url=https://foodandcity.org/food-mover-paper-plastic/|title=Food Movers: Paper or Plastic?|first=Cory|last=Leahy|date=2016-01-08|website=Food+City|access-date=8 August 2021|archive-date=8 August 2021|archive-url=https://web.archive.org/web/20210808082547/https://foodandcity.org/food-mover-paper-plastic/|url-status=live}}</ref><ref>{{Cite web|url=https://packagingguruji.com/history-facts-paper-bottle/|title=Surprisingly History Facts of Paper Bottle and FFS Machine {{pipe}} John Van Wormer|date=2021-02-26|archive-url=https://web.archive.org/web/20210226070134/https://packagingguruji.com/history-facts-paper-bottle/|archive-date=26 February 2021}}</ref>
