Gummed film refers to a technique used to measure nuclear fallout. It involves the use of a sheet of plastic (cellulose acetate) or paper substrate coated on one side with an adhesive (e.g., rubber cement). [1] The sheet is exposed (adhesive-side up) to the environment to be monitored, where fallout particles land on (and thus adhere to) the gummed film. After some period, the films are collected and analyzed for radioactivity. [2]
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation.
Blu Tack is a reusable putty-like pressure-sensitive adhesive produced by Bostik, commonly used to attach lightweight objects to walls, doors or other dry surfaces. Traditionally blue, it is also available in other colours. Generic versions of the product are also available from other manufacturers. The spelling now used is without a hyphen.
An envelope is a common packaging item, usually made of thin, flat material. It is designed to contain a flat object, such as a letter or card.
In polymer chemistry and materials science, a resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses mainly on naturally occurring resins.
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 0.25 millimetres (0.01 in) thick.
For postage stamps, separation is the means by which individual stamps are made easily detachable from each other.
In philately, gum is the substance applied to the back of a stamp to enable it to adhere to a letter or other mailed item. The term is generic, and applies both to traditional types such as gum arabic and to synthetic modern formulations. Gum is a matter of high importance in philately.
Polyvinyl acetate (PVA, PVAc, poly(ethenyl ethanoate)), commonly known as wood glue, PVA glue, white glue, carpenter's glue, school glue, or Elmer's glue in the US, is a widely available adhesive used for porous materials like wood, paper, and cloth. An aliphatic rubbery synthetic polymer with the formula (C4H6O2)n, it belongs to the polyvinyl ester family, with the general formula −[RCOOCHCH2]−. It is a type of thermoplastic.
A decal or transfer is a plastic, cloth, paper, or ceramic substrate that has printed on it a pattern or image that can be moved to another surface upon contact, usually with the aid of heat or water.
Sandpaper and glasspaper are names used for a type of coated abrasive that consists of sheets of paper or cloth with abrasive material glued to one face.
The adhesive embossed postage stamps of the United Kingdom, issued during the reign of Queen Victoria between 1847 and 1854 exhibit four features which are unique to this issue:
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a permanently assembled object created using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used.
A pouch laminator uses a lamination pouch that is usually sealed on one side. The inside of the lamination pouch is coated with a heat-activated film that adheres to the product being laminated as it runs through the laminator. The substrate side of the board contains a heat-activated adhesive that bonds the print to the substrate. This can be any of a number of board products or another sheet of laminate. The pouch containing the print, laminate, and substrate is passed through a set of heated rollers under pressure, ensuring that all adhesive layers bond to one another.
A label is a piece of paper, plastic film, cloth, metal, or other material affixed to a container or product, on which is written or printed information or symbols about the product or item. Information printed directly on a container or article can also be considered labelling.
Wrap advertising or a vehicle wrap is known as the marketing practice of completely or partially covering (wrapping) a vehicle in a vinyl material, which may be for a color change, advertising or custom delivery. The result of this process is essentially a mobile billboard. Wrap advertising can be achieved by painting a vehicle's outer surface, but an increasingly ubiquitous practice in the 21st century involves the use of large vinyl sheets as "decals". The vinyl sheets can later be removed with relative ease, drastically reducing the costs associated with changing advertisements. While vehicles with large, flat surfaces are often used, automobiles can also serve as hosts for wrap advertising, despite consisting of more curved surfaces. Wrap advertising is also used in the magazine and publishing industries.
Coated paper is paper that has been coated by a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency. Various materials, including kaolinite, calcium carbonate, bentonite, and talc, can be used to coat paper for high-quality printing used in the packaging industry and in magazines.
Adhesive tape is one of many varieties of backing materials coated with an adhesive. Several types of adhesives can be used.
Tape or Tapes may refer to:
SD Alcohol 35-A is a specially denatured alcohol containing 95.38% ethanol and 4.62% ethyl acetate. Uses of SD Alcohol 35-A include its use as the solvent in spirit gum.
Pressure-sensitive tape, known also in various countries as PSA tape, adhesive tape, self-stick tape, sticky tape, Sellotape, or just tape, is an adhesive tape that will stick with application of pressure, without the need for a solvent or heat for activation.
