PP (Polypropylene) is one of the most common materials used for beverage bottles; it can be identified by the number "5" inside the triangular recycling symbol typically found on the bottom of the bottle. This type of bottle is commonly used to package:
Small bottles for yogurt and lactic acid drinks
Squeezable soft bottles for certain sports drinks
Packaging for ready-to-drink soups that require microwave heating
Reusable sports water bottles (non-disposable)
Three Key Advantages of PP Bottles
High Heat Resistance: Capable of withstanding temperatures of approximately 100°C, making it suitable for holding hot beverages or for microwave heating.
Excellent Stability: Highly stable over time; it does not easily react with acidic beverages during prolonged storage.
Lightweight and Durable: Approximately 60% lighter than glass containers and highly resistant to breakage if dropped.
Usage Precautions
Although PP is a relatively ideal material, please keep the following in mind:
Avoid using the bottle for long-term storage of cooking oils (as seepage may occur).
If used repeatedly, it is recommended to replace the bottle every three months.
Discontinue use immediately if the bottle body appears cloudy or develops cracks.
When cleaning, avoid using steel wool or abrasive scrubbers to prevent scratching the surface.
