要とする問題がある。When an antibacterial film is produced by, for example, the extrusion laminating method,
An antibacterial agent is kneaded into the formation portion of the polyolefin layer and extruded and laminated, and the antibacterial effect is determined by the amount of the antibacterial agent exposed on the surface of the innermost layer. Usually, a method such as kneading an antibacterial agent into the entire polyolefin layer or into the innermost layer as thin as possible is taken,
Even in that case, the amount of the antibacterial agent exposed to the surface is small relative to the amount of the kneaded antibacterial agent added, and therefore it is necessary to add more than a certain amount of the antibacterial agent in order to impart sufficiently effective antibacterial properties to the film. There's a problem.

There are problems that it is difficult to set the processing conditions because the product is economically discolored and oxidized, and the amount of antibacterial agent added is limited.

And the products described in JP-A-2-192937.
According to the manufacturing method, the antibacterial agent can be sufficiently exposed on the surface of the film.
Therefore, it is much more antibacterial than a film containing an antibacterial agent.
Although there is an advantage that the effect can be improved, in the former case, the manufacturing
Not because it requires retaining film of the antimicrobial agent in a degree
It is economical and the holding film is wound up when used.
Since it is necessary to peel it off, it is said that the operation is complicated.
I have a problem.

It is difficult to set the conditions and the tension of the molten film changes.
Together, it is difficult to perform uniform spot-free spraying.

Of course, it has the advantage of not requiring operations such as separation and winding.
Of course, blowing an antibacterial agent on the carrier film or molten resin film
Compared with the technical means of attaching and adhering, spraying pressure and spraying
Setting conditions (processing conditions) such as coating amount and blowing air temperature
It is extremely easy to manufacture a film which can maintain the transfer adhesion amount of the antibacterial agent evenly on the surface of the laminate film and can exhibit a uniform antibacterial effect over the entire surface of the film .
