Claims

[Claims for Utility Model Registration] 1. A packaging material made of a base sheet having one or more resin film layers and a heat-sealing resin layer made of polyolefin resin laminated on the base sheet. In a sealed bag having a substantially rectangular profile from the front, at least three peripheral edges of the sealed bag are heat-welded parts, and at least one of the pair of opposing heat-welded parts is A score line is carved in one of the heat welds from the heat weld to the opposite heat weld, and further, the cut line is tightened so that the heat weld of the one At least one resin film layer in the base sheet in the part to be unsealed in a straight line from one part to the other heat-welded part is coated with a layer of 0.5μ to 1/2 of the thickness of the packaging material. 2. An easily openable sealed bag, characterized in that a linear tear having a depth of 2. In the easy-to-open sealed bag described in claim 1 of the utility model registration claim, at least 2 linear tears formed in the packaging material sandwich the cut line carved in the heat-welded part. An easy-to-open sealed bag formed in rows or more. 3 A linear tear formed in the base sheet in the packaging material is 2 to 2 inches wide in the area where the packaging is scheduled to be opened.
The cracks are formed over a band of 0 mm, and the distance between the cracks in the width direction is 0.002 to 5 mm.
Paragraph 1 or 2 of the claims for utility model registration that is
Easy-to-open sealed bag as described in section.
