When it comes to storing water in a refrigerator, the best type of plastic to use is high-quality food-grade polyethylene (HDPE) or polypropylene (PP). These plastics are considered safe for storing water and other beverages because they are less likely to leach harmful chemicals into the liquid.
Here are some reasons why HDPE and PP are good choices for water storage in a refrigerator:
Safety: HDPE and PP are approved by regulatory agencies, such as the U.S. Food and Drug Administration (FDA), for food contact applications. They are non-toxic and do not contain harmful substances like BPA (Bisphenol A) or phthalates, which can be found in some other plastics.
Chemical Resistance: HDPE and PP have excellent chemical resistance, which means they are less likely to react with the water or beverages stored in them. This helps maintain the purity and taste of the water.
Odor and Taste Neutral: These plastics are generally odorless and tasteless, so they won't impart any unwanted flavors or smells to the water.
Durable and Recyclable: HDPE and PP are durable materials that can withstand the rigors of daily use. They are also recyclable, making them a more environmentally friendly choice.
When choosing plastic containers for water storage, look for recycling codes on the bottom of the container. HDPE is often identified with the recycling code #2, while PP is identified with #5. Additionally, choose containers that are specifically labeled as food-grade or suitable for storing beverages.
It's important to note that while HDPE and PP are generally safe for water storage, avoid reusing plastic containers that were originally intended for non-food items or that have been used to store chemicals or other non-food substances. These containers may not be manufactured to the same food-grade standards and could pose a risk of contamination. Always clean and sanitize the containers regularly to ensure safe water storage.
