BoPET film has been used in the production of banjos and drumheads since 1958 due to its durability and acoustical properties when stretched over the bearing edge of the drum. They are made in single- and double-ply versions, with each ply being 2–10 mils (0.051–0.254 mm) in thickness, with a transparent or opaque surface, originally used ...
Two methods are widely used for producing BOPP films, namely, a bi-directional stenter process or a double-bubble blown film extrusion process. [39] Biaxial orientation increases strength and clarity. [40] BOPP is widely used as a packaging material for packaging products such as snack foods, fresh produce and confectionery.
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.
Polyvinylidene chloride is applied as a water-based coating to films made of other plastics, such as biaxially-oriented polypropylene (BOPP) and polyethylene terephthalate (PET). This coating increases the barrier properties of the film, reducing the permeability of the film to oxygen and flavours and thus extending the shelf life of the food ...

In 1982, the British Sidac plant at St Helens was closed and in 1987, UCB Films acquired La Cellophane Espanola. In 1987 the BOPP production partnership with ICI ended, and UCB Films assumed full ownership of Sidex Ltd. There followed a period of investment in the Wigton plant, raising capacity from 10,000 to 35,000 tonnes pa.
