Muovikalvon

Muovikalvon is a Finnish term that translates to "plastic film" in English. It refers to a thin, flexible sheet of plastic material. These films are produced through various manufacturing processes, primarily extrusion, where molten plastic is forced through a die to create a continuous sheet.

Plastic films are widely used across numerous industries due to their versatility, barrier properties, and cost-effectiveness. In packaging, they are essential for protecting goods, extending shelf life, and facilitating transport. Common examples include food packaging films, shrink wrap, and stretch film. The specific type of plastic used, such as polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC), determines the film's properties, including its strength, flexibility, transparency, and resistance to chemicals or moisture.

Beyond packaging, muovikalvon finds applications in agriculture as mulch films to retain soil moisture and suppress weeds, in construction for vapor barriers or protective coverings, and in manufacturing for insulation or decorative purposes. The development of specialized plastic films with enhanced properties, such as biodegradability or increased tensile strength, continues to expand their utility and address environmental concerns. The recycling of plastic films is an ongoing focus to minimize their environmental impact.
