Four Laminated Film Types for Pharma Packaging: Processes, Barrier Properties, and Applications
Laminated films are widely used in pharmaceutical packaging.
With multiple advantages, they are highly favored by pharmaceutical companies. Because there are many types, the following four laminated films are mainly used in pharmaceutical packaging today:
1: Ordinary laminated film. Produced by dry lamination, it offers good printability, barrier performance against gas and water vapor, and can also elevate the product's presentation.
2: Pharmaceutical strip easy-tear packaging material. Produced by extrusion lamination, it provides easy-tear performance and strong gas and water vapor barrier properties, helping extend drug shelf life. It also has good degradability, which benefits the environment.
3: Paper-aluminum-plastic laminated film. Produced by extrusion lamination, it delivers good printability, gas and water vapor barrier properties, and good stiffness that ensures product formability, plus good degradability for environmental benefits. In addition, medicines packaged in this film appear more premium.
4: High-temperature retort film. Produced by dry lamination, it has a strong sterilization effect: it can kill all bacteria inside the package, allowing storage at room temperature without refrigeration. It withstands high-temperature retort, provides excellent gas and water vapor barrier, can be printed on both the inside and outside, and has excellent printability. It is commonly used for liquid packaging such as infusion bags and blood bags.
