1. Polyolefin Materials
Polyolefin materials mainly include polypropylene (PP) and polyethylene (PE). These materials possess good heat resistance, chemical resistance, and plasticity, effectively protecting the quality and safety of pharmaceuticals.
2. Polyester Materials
Polyester materials mainly include polyethylene terephthalate (PET) and polypropylene terephthalate (PBT). These materials exhibit excellent heat resistance, oxidation resistance, and mechanical strength, ensuring the stability and efficacy of pharmaceuticals.
3. Composite Materials
Composite materials for pharmaceutical bottle sealing films are typically composed of multiple materials, manufactured using lamination technology. These materials are complementary in physical or chemical properties, improving the film's sealing performance, moisture resistance, and chemical resistance, thus better protecting the pharmaceuticals.
