PP is stiff, scratch-prone, and a good barrier to moisture, oil, and alcohol
Polypropylene (PP) is a common plastic that is often used in packaging and containers. It is stiffer than other plastics such as HDPE and has a scratch-prone surface. Despite this, PP is a good barrier to moisture, oil, and alcohol, and it is resistant to many chemicals. This makes it suitable for storing ethanol or isopropanol, which are the two most common hand sanitizing agents. PP is often used in yogurt containers and syrup bottles.
When compared to other traditional plastics, PP is not typically considered a "barrier" material. However, it does offer some barrier protection, especially when used in multilayer structures. For example, PP is often used in combination with EVOH (ethylene-vinyl alcohol copolymer), a material known for its superior barrier properties against gases like oxygen, nitrogen, and carbon dioxide. By incorporating EVOH into a multilayer structure with PP, the resulting packaging material can offer enhanced barrier protection against moisture and gases.
The scratch resistance of PP can be improved by combining it with other materials to form laminates. For example, PP/PA laminates have better scratch performance than PA/PP laminates due to their low surface friction, graded structure, and ability to absorb scratch energy. The thickness of the PP film also plays a role in scratch performance, with thicker films generally exhibiting better scratch resistance.
PP is a versatile material that can be used in various applications, including food packaging and containers for liquids such as alcohols. Its stiffness, scratch resistance, and barrier properties can be modified by combining it with other materials or adjusting its thickness.
