With this device, Barrow developed a process for laminating brittle documents between tissue and cellulose acetate film, as well as a highly effective means of deacidifying paper. He demonstrated the facts of paper stability over the past four centuries and developed a durable paper having a high degree of permanence.
A film blowing machine involves one process used to make plastic film. Extruded tubular processing is most often used with polyethylene films but can be used with other polymers. [1] The film may be laminating film, shrink film, agricultural covering film, bags or film for textiles and clothing, and other packaging materials.
In the United States, the most common core size found on lamination film is one inch (25- to 27-inch-wide film). Larger format laminators use a larger core, often 2 1 ⁄ 4 to 3 inches in diameter. Film is usually available in 1.5, 3, 5, 7, and 10 mil thicknesses. The higher the number, the thicker the film. A mil is one thousandth of an inch ...
A typical industrial roll-to-roll process line. In the field of electronic devices, roll-to-roll processing, also known as web processing, [1] reel-to-reel processing or R2R, [2] is the process of creating electronic devices on a roll of flexible plastic, metal foil, or flexible glass. [3]
Cold foil printing, also known as cold foil stamping, is a modern method of printing metallic foil on a substrate in order to enhance the aesthetic of the final product. . Cold foil printing can be done two ways: the older dry lamination process common in the offset printing industry, or the newer, more versatile wet lamination process, which is dominant in the flexo label indus
Polyurethane laminate (PUL, thermal stretch, [1] fuzzy rubber [1]) is a compound fabric made by laminating a cloth fabric to one or both sides of a thin film of polyurethane. [ 1 ] [ 2 ] Polyurethane laminated fabrics have a wide range of applications in medical, automotive and garment uses.
Extruded film can be stretched, thinned, or oriented in one or two directions. Blown or tubular process forces air into an extruded ring to expand the film. Flat tenter frames stretch the extruded film before annealing. [3] [4] Calender rolls can be used to form film from hot polymers [5] Solution deposition is another film forming process.
The main stages of the Lay-Up process are cutting, lamination and polymerization. [citation needed] Even though some of the production steps can be automated, this process is mainly manual (hence often referred to as the Hand Lay-Up process), leading to laminates with high production costs and low production rates with respect to other techniques.
