CORSTAR's innovative self-adhesive blown film technology leads the new trend of functional packaging

Against the backdrop of the rapid growth of the market demand for self-adhesive films, CORSTAR Machinery Co., Ltd. has successfully developed a new generation of self-adhesive film blow molding production equipment with its original co-extrusion coating integrated technology. This equipment has achieved a breakthrough in the simultaneous completion of substrate production and adhesive layer coating, and can stably produce various types of high-performance self-adhesive films, including protective films, label films, medical dressing substrates, etc., providing innovative solutions for consumer electronics, medical, logistics and other industries.

Through patented multi-layer co-extrusion technology, CORSTAR equipment can simultaneously complete substrate molding, adhesive layer coating and release film lamination, and the production speed is increased to 200 meters/minute, which is 35% more efficient than traditional processes. The PET protective film produced by an electronic company using this equipment has an adjustable range of 5-500g/25mm for adhesion, which meets the full protection needs of display screens from transportation to assembly.

Equipped with an intelligent viscosity adjustment system, an online rheometer is used to monitor the state of the adhesive layer in real time to ensure that the adhesion fluctuation range is ≤±8%. The ultra-low allergenic acrylic film developed for medical dressing applications has passed ISO 10993 biocompatibility certification and has been used in many well-known Band-Aid brands.

Innovative development of removable water-based adhesive coating technology allows self-adhesive films to achieve residue-free peeling while maintaining initial stickiness. The environmentally friendly packaging fixing film used by a logistics company has been repeatedly pasted more than 20 times and fully complies with EU REACH regulations.

Consumer electronics: OCA optical film, screen protector

Medical and health: medical tape, transdermal drug delivery substrate

Industrial: surface protection film, anti-counterfeiting label substrate

Daily chemicals: sticky notes, decorative films

The latest intelligent self-adhesive film production line launched by CORSTAR integrates AI visual inspection and automatic slitting systems, with a defect recognition accuracy of 0.05mm² and a slitting tolerance of ±0.1mm. The company is working with material research institutions to develop thermochromic adhesive film technology, which is expected to be industrialized in 2026.

Market data shows that the global self-adhesive film market is expected to exceed US$28 billion in 2025, with a compound annual growth rate of 6.7%. CORSTAR's technological innovation is driving the industry towards high precision, functionality, and environmental protection. It has currently provided customized equipment solutions for more than 20 companies in Asia and Europe.
