  • Thin walled polyethylene container
    Publication number: 20040105944
    Abstract: Thin walled polyethylene containers are suitable for the packaging of foods such as cottage cheese, ricotta cheese and ice cream. The containers have a higher softening point (which permits the containers to be “hot filled”) and high impact strength at low temperature (which is useful when a container of ice cream is dropped).
