Polypropylene screw caps, leakproof† when used with Nalgene bottles with the matching finish
Nalgene LDPE, HDPE, PP and PMP containers can be used for long-term storage, but direct UV exposure should be avoided
Nalgene reusable LDPE bottles are designed to last many years under typical laboratory conditions. Yet, as with all durable products, they need to be retired and replaced eventually. Nalgene LDPE bottles and their packaging are readily recyclable. Please recycle the corrugate cartons and LDPE bags in which your Nalgene bottles products are packaged. And at end of product life, please wash and recycle your Nalgene LDPE bottles.
