Blow molds are hollow plastic objects created using a manufacturing process called blow molding. This technique involves heating plastic until it becomes pliable, then inflating it into a mold to form the desired shape. Common products made with blow molds include containers, toys, and decorative items. One popular use of blow molds is for seasonal decorations, especially during holidays like Halloween and Christmas. These decorations often take the form of large, colorful figures, such as pumpkins or Santa Claus, that are lightweight and easy to display. Blow molds are known for their durability and weather resistance, making them suitable for outdoor use.
