Abstract
The present invention is generally directed to a process for increasing the strength of a component of a laminated absorbent article. The material basis weight of the component may be increased by introducing a material basis weight increasing agent onto at least a portion of the component. The material basis weight increasing agent comprises selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic, or isotactic configuration) are used to prepare the material basis weight increasing agents of the present invention.
