Abstract
One or more shirred artificial sausage casings are tightly packaged in a flexible film to reduce lateral and longitudinal expansion and to protect against moisture loss. The flexible film is caused to fit tightly about the artificial sausage casings by enveloping the casings within at least one flexible film, removing sufficient air from within the resulting envelope for producing a partial vacuum therein and sealing said envelope for maintaining said partial vacuum.
Claims9
A method for packaging a shirred artificial sausage casing which comprises enveloping said casing within a flexible tubular film, said film having a transmission rate for air of less than about 1cc/100in.sup.2 /24 hr.-atm removing sufficient air from within the resulting envelope to produce therein an absolute pressure of substantially not less than about 0.4 atmospheres, and then sealing said envelope for maintaining said pressure.
