公害原因を無くすることができる。The present invention utilizes the fact that the zipper tape is made of a biodegradable synthetic resin material to decompose into compost in the soil, which is a characteristic of this material, and is a non-polluting material. That is, we can provide eco-friendly zipper tape. Further, the present invention does not generate dioxin or SOx, which has been conventionally generated by discarding the opening / closing tool of the packaging bag, and is effective in view of environmental problems, safety and simplicity. In addition, since the present invention can provide an independent zipper tape so that the zipper tape can be freely attached to the mouth of the bag, the cause of pollution caused by the zipper tape made of synthetic resin that has been fixed to the mouth of the conventional bag. Can be eliminated.
