<p>PURPOSE:To ensure a superior openability without providing such an equipment requiring a special processing as a tear tape or a slit in a body seal part, prevent a package from being inadvertently peeled, lower a cost, and enhance a handleability. CONSTITUTION:A body seal part 7 is formed by thermally fusing a lap part of both ends of a wrapping film 2 covering the outer surface of a body to be wrapped 3. A side seal part is formed by heat-sealing a lap part of an upper folded part 9 and a lower folded part 10, which are formed by folding inward the extending parts of the film 2 existing out of the body to be wrapped 3. Therefore, on the outer surface of the wrapping film 2, printing is previously made in non-adhesion parts 14 including opposed surfaces of lap parts 13 of the wrapping film, which are formed on the both sides of the upper folded part 9 and the lower folded part 10 by folding the extending parts inward, whereby the non-adhesion parts 14 cannot be bonded by heat sealing.</p> |
