How to check plastic water bottles & lunchboxes are made of food grade plastic.

It's crucial to ensure that your plastic water bottles and lunchboxes are made of food-grade plastic to prevent harmful chemicals from leaching into your food and drinks. Here's how to check:

1. Look for the Resin Identification Code (Recycling Symbol):

• Most plastic products have a triangular recycling symbol, usually on the bottom, with a number inside (1 to 7). This number indicates the type of plastic resin used.
• Generally Safe Food-Grade Plastics:
• #1 PET or PETE (Polyethylene Terephthalate): Commonly used for single-serve beverage bottles (water, soda). Generally considered safe for single use, but not ideal for repeated use or hot liquids as it can degrade and leach chemicals over time.
• #2 HDPE (High-Density Polyethylene): Used for milk jugs, juice bottles, and some food storage containers. It's durable, resistant to impact, and considered very safe for repeated use.
• #4 LDPE (Low-Density Polyethylene): Found in flexible items like bread bags, some squeezable bottles, and food wraps. Generally safe for food contact but not suitable for high-heat applications like microwaving.
• #5 PP (Polypropylene): Widely regarded as one of the safest plastics for food use. It's heat-resistant, making it suitable for microwave and dishwasher use, and is commonly found in yogurt containers, straws, and reusable food storage boxes.
• Plastics to Approach with Caution or Avoid for Food Contact:
• #3 PVC (Polyvinyl Chloride): Often found in cling wrap and plumbing pipes. Can release harmful chemicals like phthalates and BPA (if it's not uPVC, which is unplasticized PVC). Generally not recommended for direct food contact, especially with heat.
• #6 PS (Polystyrene): Used for foam cups, takeout containers, and disposable cutlery. Can break down under heat and may release styrene, a possible carcinogen. Best to avoid for hot foods.
• #7 OTHER: This is a "catch-all" category. It can include various plastics, some of which may contain BPA (like polycarbonate) or other chemicals. Unless it explicitly states "BPA-free" and the material is identified (e.g., Tritan copolyester), it's best to be cautious.

2. Look for the "Fork and Cup" Symbol:

• This symbol (a wine glass and a fork) is an internationally recognized icon that means the plastic is certified safe for food contact. If you see this, it's a strong indicator of food-grade quality.

3. Check for "BPA-Free" Labeling:

• Bisphenol A (BPA) is a chemical that was commonly used in some plastics, especially polycarbonate (#7 PC), and has been linked to health concerns.
• Many manufacturers now explicitly label their products as "BPA-free." While this is a good sign, remember that some "BPA-free" plastics might use other bisphenol compounds (like BPS or BPF) which may have similar effects.
• If a product is labeled "BPA-free" and also has the recycling codes #1, #2, #4, or #5, it's generally a safer bet.

4. Consider the Product's Intended Use and Original Contents:

• If you're reusing a plastic container, consider what it originally held. Even if a bucket is made of HDPE (#2), if it previously contained chemicals, it might not be safe for food.
• Always choose containers specifically designed for food storage.

5. Avoid Heating Plastics (Even "Microwave-Safe" Ones) When Possible:

• Even plastics considered food-safe can sometimes degrade or leach chemicals when exposed to high heat. While PP (#5) is generally microwave-safe, it's often best to transfer food to glass or ceramic before microwaving if you have concerns.

In summary, for the safest options, prioritize plastic water bottles and lunchboxes that have:

• Recycling codes #2 (HDPE), #4 (LDPE), or #5 (PP).
• The "fork and cup" symbol.
• A clear "BPA-free" label.

When in doubt, glass and stainless steel alternatives are generally the safest and most durable options for food and beverage storage.
