Abstract
An overwrap packed body is obtained by heating and shrinking a wrapping material in a condition that five drink products collectively wrapped by the wrapping material. Three perforated lines passing through gap portions between the adjacent drink products are formed on the wrapping material at an interval of 2 mm in parallel. When the three perforated line portions are pushed with fingers in the gap portion between the adjacent drink products, the wrapping material torn from the pushed portion in a vertical direction. Thus, the packed drink products DG can be easily taken out one by one.
