Elastomeric articles, such as gloves (10), are made by welding together two plies of a multi- layer film (40). The film plies are welded together through ultrasonic bonding, thermal bonding, or mixtures thereof. The multi -layer film (40) includes at least three layers (42,44,46) that, in one embodiment, are coextruded. Each layer (42,44,46) of the multi -layer film is made from a different composition that produces layers having different properties. |
