Mono films are typically used for packaging food, beverages and other industrial products that do not require a large barrier. They are ideal for applications where a lightweight, cost-effective and visually appealing packaging solution is required.
The choice of polymer for a monolayer film would depend on several factors such as the required film properties (e.g. strength, flexibility, transparency, barrier properties), the printing process and the intended use of the film.
Common polymers used for monolayer films:
Polyethylene (PE), Polypropylene (PP), Polyethylene Terephthalate (PET) and Polyamide (PA).
PE and PP are widely used for flexible packaging due to their excellent flexibility, toughness and sealing properties. PET is known for its excellent transparency, rigidity and barrier properties. PA is used for its excellent puncture resistance and gas and odour barrier properties.
In general, single-layer printed films are a versatile and cost-effective option for a variety of packaging applications as they offer excellent print quality and customisation options.
