PROBLEM TO BE SOLVED: To arrange a plurality of products such as canned food side by side to be disposed in one stage or in a plurality of stacked stages, wind a plastic film having an easily tearable direction around a group of the products, and form an unsealing means for making the tearing of the plastic film easy on the film. SOLUTION: An unsealing means is formed with a continuous weakened portion A extending in a lateral direction with respect to an easily tearable direction D of a plastic film, and this continuous weakened portion A forms a band 6 surrounding a product pack. This continuous weakened portion A can withstand tension stress applied to the plastic film 3, which tightens the products, and has such a mechanical characteristic as to open the plastic film 3 at an arbitrary position of the continuous weakened portion A without using a tool. |
