--- The Origins of Soft Packaging Films ---• Early Developments in Packaging Materials:The journey of soft packaging films began in the mid-20th century when the demand for lightweight, durable, and cost-effective packaging solutions surged across industries. Initially, simple polyethylene (PE) films were used for basic packaging needs—such as wrapping groceries or storing raw materials—due to their flexibility, moisture resistance, and low production cost. However, these early films lacked advanced barrier properties, limiting their application in sensitive sectors like electronics and pharmaceuticals. As industrial demands grew, so did the need for more sophisticated materials. In the 1980s, the introduction of multilayer composite films marked a turning point. Companies began combining layers of PET (polyethylene terephthalate), aluminum foil, and PE (polyethylene) to create vacuum-sealed bags with superior oxygen, moisture, and light barriers. One notable real-world example is Kunshan Topclean Purification Technology Co., Ltd., founded in 2008, which emerged during this transformative period. With over 15 years of experience, Topclean pioneered the use of virgin-grade materials in its composite vacuum bags—featuring a 20–25% PET outer layer, 10–15% pure aluminum foil barrier, and 60–70% LLDPE/mPE inner layer—ensuring compliance with ISO 9001 and FDA standards. A key milestone came in 2015 when Topclean supplied high-performance composite packaging bags to a leading semiconductor manufacturer in Suzhou.
