Mullifilm
Mullifilm is a brand of transparent cellulose film produced by the former Mullard company. This material was widely used in the mid-20th century as a packaging and wrapping material for various consumer goods. Its key properties included clarity, a degree of stiffness, and a barrier against moisture and grease. Mullifilm was often seen on products like confectionery, baked goods, and stationery. The film was derived from regenerated cellulose, a process that breaks down wood pulp or cotton linters and then reforms them into a thin sheet. While effective for its time, mullifilm has largely been superseded by more modern plastic films like cellophane, polyethylene, and polypropylene, which offer a wider range of properties and often lower production costs. The Mullard company, primarily known for its electronics, diversified into film production for a period, and mullifilm represents a segment of this industrial activity. Its historical significance lies in its role as an early example of transparent flexible packaging that contributed to product presentation and preservation before the widespread adoption of plastics.
