It was formed by applying a release varnish mainly composed of thermoplastic resin such as urethane-based resin or polyamide-based resin or a mixture of these resins. It is necessary to control and manufacture the opening width (peeling strength) of the sheet (20) in a narrow range of 20 g to 40 g, and therefore, the productivity of the stable lid material is lacking. When the sheet (20) was peeled off, there was a problem that the opening property (peeling property) of the topsheet (20) was unstable and a light opening property (peeling property) could not be obtained.

The instant food container such as fried noodles is sealed, and the lid (1) with the hot water hole of the instant food container of the present invention as described above includes:
As shown in FIG. 4, hot water is poured into the container (2) and left for a few minutes to warm the instant food (not shown) in the container (2) to soften and loosen the food. Pull up the pull tab (14) on the outer periphery and pull up the surface sheet (2).
The surface sheet (20) in the easily peelable area (L1) is broken into the composite sheet (10) while breaking the perforations (22) applied to the area (0).
From the composite sheet (10) in the easily peeled area (L1)
In this case, the hot water for softening the instant food is heated by exposing the ready-to-eat food by softening the instant food by adding wax to the easily peelable layer (30) shown in FIG. The wax contained therein bleeds (bleeds out), the adhesive strength with the outer surface of the composite sheet (10) (the side opposite to the instant food side) is reduced, and light peelability can be obtained. .

Light peeling of the topsheet (20) was obtained at a temperature of from 85 ° C to 85 ° C, and a relatively strong adhesive force was required at a water temperature close to room temperature. On the other hand, in the lid material of Comparative Example 1, even when hot water was poured, the peel strength (adhesive strength) did not change and was almost the same as the adhesive strength at room temperature and was difficult to peel. Therefore, even if the control range of the peel strength for obtaining the easily peelable layer (30) is, for example, the upper limit of 60 to 70 g / 15 mm, the peel strength becomes sufficiently light by the heat of the hot water, and the productivity is easily improved. A release layer (30) was obtained.

軽い剥離性を得ることができる。As described above, the present invention has the following effects. That is, the composite sheet and the topsheet are divided into an easy-peeling area and an adhesive area by an easy-peeling layer formed by applying an easy-peeling agent to a predetermined shape area, and are laminated and adhered to each other, and adhere to the easy-peeling area. A perforated surface sheet corresponding to the boundary of the region is provided with a perforated lid material of an instant food container in which one to several perforated holes are formed in the composite sheet in the easily peelable region, 5% by weight of an easy-release agent (release varnish) for forming the easy-release layer
９５95% by weight of wax, and the wax is made of polyethylene wax, polyester wax, fatty acid amide wax or a mixture thereof. When exposing the hot water hole drilled in the easy-peeling area of the composite sheet, the heat of the hot water for softening the instant food softens, the contained wax component bleeds (phenomena leaching), and the composite sheet The adhesive strength with the outer surface (the surface opposite to the instant food side) is reduced, and light releasability of the topsheet can be obtained.
【００２６】即ち常温では、必要他程度の接着力を持ち

る。That is, at room temperature, an easy-peelable layer having an adhesive force of a necessary degree or less and capable of reducing the adhesive force by the heat of hot water can be provided with a large control width in the step of forming the easy-peelable layer. It also contributes to improving productivity.
