Cardboard
Cardboard is a generic term for heavy paper-based products. The construction can range from a thick paper known as paperboard to corrugated fiberboard which is made of multiple plies of material. Natural cardboards can range from grey to light brown in color, depending of the specific product; dyes, pigments, printing, and coatings are available. The term "cardboard" has general use in English and French, but the term cardboard is deprecated in commerce and industry as not adequately defining a specific product. Material producers, container manufacturers, packaging engineers, and standards organizations, use more specific terminology. Statistics In 2020, the United States hit a record high in its yearly use of one of the most ubiquitous manufactured materials on earth, cardboard. With around 80 per cent of all the products sold in the United States being packaged in cardboard, over 120 billion pieces were used that year. In the same year, over 13,000 separate pieces of con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper Recycling
The recycling of paper is the process by which waste paper is turned into new paper products. It has a number of important benefits: It saves waste paper from occupying homes of people and producing methane as it breaks down. Because paper fibre contains carbon (originally absorbed by the tree from which it was produced), recycling keeps the carbon locked up for longer and out of the atmosphere. Around two-thirds of all paper products in the US are now recovered and recycled, although it does not all become new paper. After repeated processing the fibres become too short for the production of new paper, which is why virgin fibre (from sustainably farmed trees) is frequently added to the pulp recipe. There are three categories of paper that can be used as feedstocks for making ''recycled paper'': mill broke, pre-consumer waste, and post-consumer waste. ''Mill broke'' is paper trimmings and other paper scrap from the manufacture of paper, and is recycled in a paper mill. ''Pre-c ...

Recycling
Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling). Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, and Recycle" waste hierarchy. It promotes environmental sustainability by removing raw material input and redirecting waste output in the economic system. There are some ISO standards related to recycling, such as ISO 15270:2008 for plastics waste and ISO 14001:2015 for enviro ...

Bookbinding
Bookbinding is the process of physically assembling a book of codex format from an ordered stack of ''signatures'', sheets of paper folded together into sections that are bound, along one edge, with a thick needle and strong thread. Cheaper, but less permanent, methods for binding books include loose-leaf rings, individual screw-posts (binding posts), twin loop spine coils, plastic spiral coils, and plastic spine combs. For protection, the bound stack of signatures is wrapped in a flexible cover or is attached to stiffened boards. Finally, an attractive cover is placed onto the boards, which includes the publisher's information, and artistic decorations. The trade of binding books is in two parts; (i) stationery binding (vellum binding) for books intended for handwritten entries, such as accounting ledgers, business journals, blank-page books, and guest logbooks, and notebooks, manifold books, day books, diaries, and portfolios. (ii) letterpress printing and binding deals with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrugated Fiberboard
Corrugated fiberboard or corrugated cardboard is a type of packaging material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used for making corrugated boxes. The corrugated medium sheet and the linerboard(s) are made of kraft containerboard, a paperboard material usually over thick. History Corrugated (also called pleated) paper was patented in England in 1856, and used as a liner for tall hats, but corrugated boxboard was not patented and used as a shipping material until 20 December 1871. The patent was issued to Albert Jones of New York City for single-sided (single-face) corrugated board. Jones used the corrugated board for wrapping bottles and glass lantern chimneys. The first machine for producing large quantities of corrugated board was built in 1874 by G. Smyth, and in the same year Oliver Long improved upon Jones' design by inventing corrugated board with liner sheets on both ...

Wet Strength
The wet strength of paper and paperboard is a measure of how well the web of fibers holding the paper together can resist a force of rupture when the paper is wet. Wet strength is routinely expressed as the ratio of wet to dry Tensile strength, tensile force at break. With combined board such as corrugated fiberboard or with laminations, wet strength also includes the ability to stay intact under humid or wet conditions. Wet strength adhesives are often needed. Mechanism The cellulose fibreweb of paper is mainly held together by hydrogen bonds. These are dependent on physical contact between the fibres and can be broken by wetting of the fibres. The residual strength of a wetted paper can be less than 10% of the original strength. Various techniques, such as refining of the pulp (paper), pulp and wet pressing on the paper machine can be used to reduce the strength loss of the paper upon wetting. To improve the wet strength it is common to use chemicals. The use of chemicals c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Postcard
A postcard or post card is a piece of thick paper or thin cardboard, typically rectangular, intended for writing and mailing without an envelope. Non-rectangular shapes may also be used but are rare. There are novelty exceptions, such as wooden postcards, copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut "postcards" from tropical islands. In some places, one can send a postcard for a lower fee than a letter. Stamp collectors distinguish between postcards (which require a postage stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed and sold by a private company, individual or organization, a postal card is issued by the relevant postal authority (often with pre-printed postage). Production of postcards blossomed in the late 19th and early 20th centuries. As an easy and quick way for individuals to communicate, they became extremely popular. The study and collecting of postcards is terme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carton
A carton is a box or container usually made of liquid packaging board, paperboard and sometimes of corrugated fiberboard. Many types of cartons are used in packaging. Sometimes a carton is also called a box. Types of cartons Folding cartons A carton is a type of packaging typically made from paperboard that is 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. More recently, egg cartons have also been made fro ...

Paperboard
Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 Inch#equivalences, points) than paper and has certain superior attributes such as foldability and rigidity. According to International Organization for Standardization, ISO standards, paperboard is a paper with a grammage above 250 g/m2, but there are exceptions. Paperboard can be single- or multi-ply. Paperboard can be easily cut and formed, is lightweight, and because it is strong, is used in packaging. Another end-use is high quality graphic printing, such as book and magazine covers or postcards. Paperboard is also used in fine arts for creating sculptures. Sometimes it is referred to as ''cardboard'', which is a generic, lay term used to refer to any heavy pulp (paper), paper pulp–based board, however this usage is deprecated in the paper, printing and packaging industries as it doe ...

Playing Cards
A playing card is a piece of specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic that is marked with distinguishing motifs. Often the front (face) and back of each card has a finish to make handling easier. They are most commonly used for playing card games, and are also used in magic tricks, cardistry, card throwing, and card houses; cards may also be collected. Some patterns of Tarot playing card are also used for divination, although bespoke cards for this use are more common. Playing cards are typically palm-sized for convenient handling, and usually are sold together in a set as a deck of cards or pack of cards. The most common type of playing card in the West is the French-suited, standard 52-card pack, of which the most widespread design is the English pattern, followed by the Belgian-Genoese pattern. However, many countries use other, traditional types of playing card, including those that are German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
