ABSTRACT OF THE DISCLOSURE
A bag that is suitable for receiving blood from
animals being exsanguinated is made by folding a sheet of
liquid impermeable thermoplastic film back upon itself and
folding down the top edges to form a top portion four sheet
layers thick. An aperture is cut out of the top portion using
a hot die which fuses the four layers together at the perimeter
of the aperture. The handle provided by the aperture is
strong enough to support the bag when filled with blood, and
it also partially closes the bag to reduce the potential for
contamination and spillage.
