Titanium dioxide. also referred to as titanium dioxide. is a versatile compound highly regarded for its exceptional reflective capabilities. It boasts a refractive index surpassing that of diamond. allowing it to bounce off over 70% of visible light and nearly 98% of ultraviolet light. This impressive reflectivity makes it a preferred substance in various fields. such as in sunscreens. paints. plastics. and paper. where its main purpose is to disperse and deflect light. Furthermore. it demonstrates remarkable concentration abilities suitable for incorporating into solar cells and advanced technology sensors.

Injection Stretch Blow Molding (ISBM) is a widely used technology for producing high-quality, transparent plastic bottles and containers. However, it has its disadvantages. First, the initial setup and machinery costs can be high, making it less accessible for small-scale production. The process also requires precise control and expertise to ensure consistent product quality, increasing operational complexity. Additionally, the high energy consumption during the ISBM process can lead to increased production costs and environmental impact. The technique can also limit the types of materials used, primarily favoring PET and similar plastics, which can restrict design flexibility. Despite these drawbacks, ISBM remains popular for its ability to produce strong, lightweight, and complex shapes with excellent clarity and barrier properties.

Diapers are typically made from a combination of polyethylene and polypropylene. Polyethylene is often used in the outer lining of the diaper to provide a liquid-resistant barrier, ensuring that moisture is retained within the diaper and does not leak out. On the other hand, polypropylene is commonly used in the inner layer that touches the baby's skin because of its soft texture and its ability to wick moisture away from the skin, helping to keep the area dry and comfortable. Additionally, these materials are chosen for their durability and flexibility, ensuring the diaper can withstand movement without breaking or losing shape. Given the need for diapers to be both absorbent and skin-friendly, manufacturers utilize the unique properties of both polyethylene and polypropylene to meet these requirements effectively.
