the art, science, and technology of papermaking addresses the methods, equipment, and materials used to make paper and cardboard, these being used widely for printing, writing, and packaging, among many other purposes and useful products.today almost all paper is manufactured using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression.
the container compression test measures the compressive strength of packages such as boxes, drums, and cans. it usually provides a plot of deformation vs compressive force. it is commonly used to evaluate shipping containers made of corrugated fiberboard as well as wooden boxes and crates.
carton-pierre was a material used for the making of raised ornaments for wall and ceiling decoration. it is composed of the pulp of paper mixed with whiting ground calcium carbonate and glue, this being forced into plaster moulds backed with paper, and then removed to a drying room to harden. it is much stronger and lighter than common .
a die is a specialized tool used in manufacturing industries to cut or shape material mostly using a press.like molds, dies are generally customized to the item they are used to create.products made with dies range from simple paper clips to complex pieces used in advanced technology.
the process starts by making corrugated board on a corrugating line, a long series of linked machines which may be in size of a football field. a finished piece of singlewall corrugated board is a single corrugated layer sandwiched between two liners.
kraft paper or kraft is paper or paperboard produced from chemical pulp produced in the kraft process. sack kraft paper, or just sack paper, is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most
corrugated board is stiffer and more suitable for shipping containers and protecting its contents. cardboard is better suited for printing and is used for cereal boxes and other similar light weight consumer packaging. corrugated board is manufactured in varying strengths and thicknesses.
heavier grades of paper provide more weight-bearing ability than old newspapers. creped cellulose wadding is also available. movers often wrap objects with several layers of kraft paper or embossed pulp before putting them into boxes. corrugated fiberboard pads – multi-layer or cut-and-folded shapes of corrugated board can be used as cushions.
corrugated board is manufactured on large high-precision machinery lines called corrugators, usually running at about 500 feet per minute 150 m/min or more. these machines, over time, have become very complex with the objective of avoiding some common problems in corrugated board production, such as warp and washboarding.
a tube, squeeze tube, or collapsible tube is a collapsible package which can be used for viscous liquids such as toothpaste, artist's paint, adhesive, caulk, ointments, and so on.basically, a tube is a cylindrical, hollow piece with a round or oval profile, made of plastic, paperboard, aluminum, or other metal.in general, on one end of the tube body there is a round orifice, which can be .
depending on the packaging operation and the food, packaging machinery often needs specified daily wash-down and cleaning procedures. health risks of materials and chemicals used in food packaging need to be carefully controlled. carcinogens, toxic chemicals, mutagens etc. need to be eliminated from food contact and potential migration into foods.
the container compression test measures the compressive strength of packages such as boxes, drums, and cans. it usually provides a plot of deformation vs compressive force.. it is commonly used to evaluate shipping containers made of corrugated fiberboard as well as wooden boxes and crates.industrial and consumer packages other than boxes can also be subjected to compression testing: drum .
the process starts by making corrugated board on a corrugating line, a long series of linked machines which may be in size of a football field. a finished piece of singlewall corrugated board is a single corrugated layer sandwiched between two liners. skilled workers prepare job tickets for each stack of box blanks and route the blanks to .
corrugated fiberboard is a combination of paperboards, usually two flat liners and one inner fluted corrugated medium. it is often used for making corrugated boxes for shipping or storing products. this type of cardboard is also used by artists as original material for sculpting.
die cutting is the general process of using a die to shear webs of low-strength materials, such as rubber, fibre, foil, cloth, paper, corrugated fibreboard, chipboard, paperboard, plastics, pressure-sensitive adhesive tapes, foam, and sheet metal.in the metalworking and leather industries, the process is known as clicking and the machine may be referred to as a clicking machine.
solid unbleached board sub : board made from unbleached chemical pulp; containerboard: a type of paperboard manufactured for the production of corrugated fiberboard. corrugated medium: the inner fluted portion of corrugated fiberboard; linerboard: a strong stiff board for one or both sides of corrugated boxes.
box plural: boxes describes a variety of containers and receptacles for permanent use as storage, or for temporary use, often for transporting contents.. boxes may be made of durable materials such as wood or metal, or of corrugated fiberboard, paperboard, or other non-durable materials.the size may vary from very small e.g., a matchbox to the size of a large appliance.
evidence packaging involves the specialized packaging methods and materials used for physical evidence.items need to be collected at a crime scene or a fire scene, forwarded to a laboratory for forensic analysis, put in secure storage, and used in a courtroom.items might include dna, hair samples, body parts, blood samples, sperm, knives, vomit, firearms, bullets, fire accelerants, computers .
strapping, also known as bundling and banding, is the process of applying a strap to an item to combine, stabilize, hold, reinforce, or fasten it. the strap may also be referred to as strapping.strapping is most commonly used in the packaging industry
containerboard ccm or corrugated case material is a type of paperboard specially manufactured for the production of corrugated board. it includes both linerboard and corrugating medium or fluting , the two types of paper that make up corrugated board.
pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or rags.mixed with water and other chemical or plant-based additives, pulp is the major seven trust material used in papermaking and the industrial production of other paper products.
