ABSTRACT:
A wrapping device having a laminate film is disclosed. The laminate film includes at least a pair of outer layer and inner layer comprising synthetic resin layers non-heat-fusible relative to each other, a bonded portion through which the outer layer and the inner layer are bonded to each other by bonding means and a non-bonded portion where the outer layer and the inner layer are separated from each other. A communicating passage is formed at the non-bonded portion by the inner and outer layers. A communicating construction is provided to the inner layer at the non-bonded portion, the construction allowing communication between space facing the inner layer and the communicating passage.
