How many grams does a cup hold?
A paper cup is a disposable cup made out of paper and lined with plastic or wax to prevent liquid from leaking out or soaking through the paper.It may be made of recycled paper and is used around the world.
Paper was invented in China in the 2nd century BC.Paper cups were used to serve tea.They were constructed in a variety of sizes and colors.There is evidence of paper cups in a description of the Yu family's possessions.[6]
The paper cup was developed in the 20th century.In the early 20th century, it was common for people to share glasses and dippers at water sources.Public health concerns were caused by this shared use.The study "Death in School Drinking Cups" was published in Technical World Magazine in August 1908, based on research carried out in Easton, Pennsylvania's public schools.The article was distributed by the Massachusetts State Board of Health.[7]
As paper goods became cheap and cleanly available, local bans were passed on the shared-use cup.The Lackawanna Railroad began using disposable paper cups in 1909.Paper cups replaced the public glasses in railway carriages by 1917.[8]
Hospitals use paper cups for health reasons.In 1942, the Massachusetts State College found that the cost of re-using glasses was 1.6 times that of single-service paper cups.The use of paper cups in hospitals was encouraged by these studies.
The brand name for a line of disposable paper cups was developed in the United States in 1907 by Lawrence Luellen, a lawyer in Boston, Massachusetts, who was concerned about germs being spread by people sharing glasses or dippers at public supplies of drinking water.Hugh Moore embarked on an advertising campaign to educate the public and to market his machine, principally to railroad companies, after Luellen developed an ice-cooled water-vending machine with disposable cups.The door for the paper cup was opened thanks to Professor Davison's study.The cool water dispensers became standard equipment on trains.
The American Water Supply Company of New England was started by Lawrence Luellen after he invented his paper cup and water fountain.The company started making the cup as well as the water vendor.The American Water Supply Company of New York was organized by Luellen with the help of Hugh Moore.These subsidiary companies were charged with the sale and distribution of Luellen's products.The Public Cup Vendor Company in New York was started in 1909 by Luellen and Moore.Railroads wanted the devices to be used on passenger train cars.Steady orders for Luellen's machine began to roll in after many states banned the common drinking cup.The Individual Drinking Cup Company of New York was inspired by Luellen and Moore's success.
The name of the cup came from a line of dolls made in New York.Success led the company, which had existed under a variety of names, to call itself the Dixie Cup Corporation and move to a factory in Wilson, Pennsylvania.There was a large water tank on top of the factory.10
The American Can Company merged with Dixie in 1957.American Can's paper business was purchased by the James River Corporation.Georgia-Pacific is a subsidiary of Koch Industries, which is the second largest privately owned company in the United States.Production moved to a modern factory in Pennsylvania in 1983.The original factory in Wilson has been empty ever since.Conrail abandoned the Easton & Northern railroad branch due to the closing of the factory.
The logo for the Dixie Cup was created in 1969 by Saul Bass.
The tone of many of the advertisements created by the Dixie Cup Company took the form of embracing modern ideals and marketing towards people who wanted to improve their lives and jump on board a new trend for fear of being left behind.The age of dixie cups was used for several years with success.
The pivot towards soda fountains was made in both product line and advertising, but the central idea of individual use remained the same.The cups being touched only by you was seen as an act to make the cups seem individualized.
The base paper for paper cups is called "cup board", and is made on special multi-ply paper machines.There is a barrier coating on it.The paper needs to be strong.The cup board grade has a special design.The plastic coating is needed for the mouth roll forming process.The cup's handling properties are provided by a well formed mouth roll.170–350 g/m2 is the basis weight of the cup boards.It was [13].
Paper cups are usually made from virgin materials.The exception to this is when the paper cup has an extra layer for heat retention, which never comes into contact with the beverage, such as a corrugated layer wrapped around a single-wall cup.
Paper cups for hot drinks used to be made waterproof by dropping a small amount of clay in the bottom of the cup and then spinning at high speed so that the clay would travel up the walls.This resulted in drinks smelling and tasting cardboard.
The cups for cold drinks could not be treated the same way as condensation forms on the outside and soaks into the board, making the cup unstable.The technique of spraying both the inside and outside of the cup with wax was developed to remedy this.The process of covering the surface of the board with a thin layer of PE was used to make the cups.
A new kind of cup (food service) board which uses no wax or plastic for waterproofing, can be recycled as part of the normal paper and board waste stream, biodegraded, or even composted in small quantities.There are no comments at this time.
Smart Planet Technologies launched "reCUP" for the UK market, a recyclable paper cup using a polyethylene and mineral-blended coating branded EarthCoating, that is engineered to be recycled through traditional paper recycling systems.Paper cups with EarthCoating are sold by several companies.
Paper cups and paper bags made from pineapple leaves were introduced in 2019.The Department of Trade and Industry Design Center of the Philippines (DCP), along with Ideatechs Packaging Corporation, Nature's Fresh, and Cagayan de Oro Handmade Paper, developed the water-resistant food packaging alternative material.The Wood Pencil Awardee was in the D&AD Future Impact Awards.The 55.32 percent mass loss of Pinyapel in four weeks is much higher than the 21.33 percent loss in commercial paper bags, according to tests by the DCP.[16]
Paper cups used to be printed using rubber blocks mounted on cylinders.With the use of mounting systems it became easier to register across the colors, allowing for more complex designs.When producing over a million cups, manufacturers use printing flexographic because it's ideal for long runs.The extra large reels that are required by paper cup manufacturers are taken by machines such as Comexi.Water-based inks are being used instead of solvent based ones.One of the drawbacks of using solvent-based ink is that hot drink cups can smell of solvent, whereas water based ink has eliminated this problem.offset printing can vary from 10,000 to 100,000 cups.The latest soya-based inks have reduced the danger of cups smelling and have also been developed for offset printing.Direct-printing, which allows printing on very small quantities, typically from 1,000 cups, and is used by companies such as Brendos, is the latest development.This type of printing is expensive and only used for items like ice cream containers.
Paper cups are usually designed for a single use.Only a small amount of recycled paper is used to make cups.Composting and recycling of paper cups are rare because of the difficulty in separating the plastic in the cups.In the UK, only two facilities are able to properly recycle PE-coated cups; in the absence of such facilities, the cups are taken to landfill or incinerated.
A UK-based business group James Cropper have developed the world's first facility for the effective recycling of the estimated 2.5 billion paper coffee cups used by British businesses each year, and have become one of 14 international companies to formally join the Paper Recovery and Recycling Group.There is a citation needed.
The Queen opened James Cropper's Reclaimed Fibre Facility in July of 2013).Although paper cups are made from renewable resources, paper products in a landfill might not break down or release methane.
A Newport Beach, California, company, Smart Planet Technologies has developed a new coating on paper cups and folding cartons called EarthCoating so they are universally recyclable in conventional paper recycling systems.Paper cups with EarthCoating have received the highest "AAA" rating for recycling from The Green Dot, a certifying body for the EU.Paper cups with EarthCoating, branded "RecycleMe", are used in recycled paper products such as copy paper, gift wrap, and paper bags.The tyke cup problem was solved in Australia.Australia's Department of Defense and Veolia have joined forces to recycle paper cups as part of their "War on Waste".[19]
A new kind of cup (food service) board which uses no wax or plastic for waterproofing, can be recycled as part of the normal paper and board waste stream, biodegraded, or even composted in small quantities.There are no comments at this time.
Water effluents are created by the manufacture of paper.Paper cups may consume more non-renewable resources than cups made of polystyrene foam.[20][21]
A life cycle inventory shows the environmental effects of both paper and plastic cups.[22]
The process of biodegrading of the paper it coats can be slowed by the use of PE on paper cups.
Some paper cups are coated with Polylactic acid.PLA is certified compostable in industrial composting facilities, which means that when it biodegrades, it does not leave behind any toxic residues.PLA-lined cups are the only paper cups that can be composted fully, so they can taint the waste stream.[ 24]
Prior to 2012 paper cups can only be recycled at a special facility.[25]
