BIODEGRADABLE BREATHABLE FILM AND LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a biodegradable and breathable film and laminate including a nonwoven web.

SOLUTION: The biodegradable breathable film is formed by mixing a biodegradable polymer with a particulate filler, forming the mixture into a film, and stretching the film uniaxially or biaxially to cause voids to form around the filler particles. The film may be laminated to a fibrous nonwoven web to form a laminate, and the fibrous nonwoven web may also be formed from a biodegradable polymer. The biodegradable film and laminate are useful in a wide variety of disposable personal care absorbent articles and disposable medical articles.
