Editing Carton (section)

===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>
