What Is a Bulk Film?
Bulk film refers to a type of film created by stretching plastic materials into thin sheets.
This film is produced through a series of steps: mixing the plastic raw materials with additives, melting them at high temperatures, extruding the molten mixture through a die, cooling it to form a solid sheet, and then stretching and winding it into rolls. The stretching process is key to enhancing the film’s strength and transparency.
Widely used in applications such as packaging, labels, tapes, and film bags, bulk film boasts high transparency and strength, making it suitable for additional processes like printing and coating. Its lightweight and flexibility also make it convenient for transportation and handling.
