Plastic films are thin sheets made from various types of polymers, such as polyethylene and polypropylene. They are widely used in packaging, agriculture, and construction due to their flexibility, durability, and resistance to moisture. These films can be transparent or opaque and are often used to protect products or create barriers. In addition to packaging, plastic films are also utilized in applications like greenhouses and insulation. They can be produced in different thicknesses and can be treated to enhance properties like UV resistance or adhesion. Their versatility makes them an essential material in many industries.
