The correct Answer is:
To determine the materials commonly used for printed materials and baby feeding bottles, we can analyze the options provided: polyamide, polyurethane, polyester, and polystyrene. ### Step-by-Step Solution: 1. **Identify the materials**: The question lists four types of polymers: polyamide, polyurethane, polyester, and polystyrene. 2. **Understand the properties of each polymer**: - **Polyamide**: Commonly used in textiles, such as nylon, but not typically used for printed materials or baby bottles. - **Polyurethane**: A thermosetting polymer, often used in foams and coatings, but not suitable for baby bottles or printed materials. - **Polyester**: Generally used in clothing and textiles, but not specifically known for printed materials or baby bottles. - **Polystyrene**: Known for its ease of molding and is widely used for making containers, including baby feeding bottles, as well as printed materials. 3. **Determine the best fit**: Given the analysis, polystyrene is the most suitable material for both printed materials and baby feeding bottles due to its properties of being easily molded and its common use in these applications. 4. **Conclusion**: Therefore, the correct answer to the question is polystyrene. ### Final Answer: Printed materials and baby feeding bottles are generally made of **polystyrene**. ---
