发明名称 Silent film for ostomy pouches
摘要 This invention relates to films which have a high degree of silence and pliability and comprise at least one layer formed from a polymeric blend which includes about 40% to 60% by weight of any ethylene and vinyl-acetate copolymer and about 60% to 40% by weight of an elastomeric polyolefin. The elastomeric polyolefin preferably comprises a blend or "alloy" of an ethylene and vinyl-acetate copolymer and an elastomeric ethylene and propylene copolymer. Such films are particularly useful for manufacturing drainage containers or bags for medical applications.
