Kiletööstuses

Kiletööstus refers to the industry involved in the production and processing of plastic films. These films are ubiquitous in modern life, serving a wide range of applications across various sectors. The primary raw materials for plastic films are derived from petroleum, with common polymers including polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC).

The manufacturing process typically involves extrusion, where molten plastic is forced through a die to create a continuous sheet. This sheet can then be stretched, cooled, and wound into rolls. Different types of films are produced through variations in this process, such as blown film extrusion for bags and packaging, and cast film extrusion for stretch wrap and other applications requiring high clarity and strength.

The applications of plastic films are extensive. They are crucial in the food industry for packaging, preserving freshness, and extending shelf life. In agriculture, films are used as mulch to suppress weeds, conserve moisture, and regulate soil temperature. The construction industry utilizes films for waterproofing, insulation, and vapor barriers. Furthermore, plastic films are integral to consumer goods packaging, electronics protection, and even medical applications.

Environmental concerns related to plastic waste have led to increased focus on developing more sustainable practices within the kiletööstus. This includes efforts to improve recycling rates, develop biodegradable and compostable film alternatives, and reduce the overall consumption of plastic materials. Innovations in material science and manufacturing processes continue to shape the future of this vital industry.
