Promotional Water Bottles and Safety

Plastic Recycling Symbols

Perhaps the most frequent question we get at InkHead concerning promotional water bottles concerns whether the plastic bottles contain chemicals which will leach into the water, specifically bisphenol A (BPA). BPA is a xenoestrogen, an endocrine disruptor which affects hormones in the body. Though still disputed in some circles, studies have linked BPA to breast and uterine cancer in women, decreased levels of testosterone in men, insulin resistance, and Type 2 diabetes. It is especially harmful to babies and small children.

BPA may leach from hard plastic lexan bottles, including Nalgene and other bottles identified by the #7 (OTHER) recycling symbol. These bottles are made with polycarbonate plastics, which are very popular for their durability and their ability to hold bright colors. In InkHead’s water bottle section on the website we have a subsection specifically for polycarbonate bottles, but we feel we must disclose that some polycarbonates have been known to introduce BPA to drinking water.

Water bottles marked as #2 HDPE (high density polyethylene), #4 LDPE (low density polyethylene), or #5 PP (polypropylene) are perfectly safe for repeated use and have not been shown to leach chemicals into drinking water.

Bottled water sold in stores is usually packaged in #1 PETE (polyethylene terephthalate) plastic bottles and are only intended for one-time use. When you’re done with the bottled water from the store, toss the bottle into the recycling bin. Better yet, get a #2, #4, or #5 plastic water bottle (or one of our stainless steel bottles) and refill it with filtered water — it’s cheaper in the long run and helps to reduce the manufacture of single-use bottles.
