Abstract
A venting apparatus is disclosed herein. The venting apparatus comprises a substrate, such as a metal substrate or a specialty plastic substrate, having an opening therein and a fluoropolymer membrane, such as ePTFE, disposed over said opening and thermally bonded using a thermoplastic material to said substrate. This allows the fluoropolymer membrane to be directly bonded to the said substrate without using an adhesive layer.
