A method for preparing a twist and seal flexible article, comprising:
- a) providing a flexible article comprising:
- i) a front panel and a back panel, each comprising a flexible substrate;
- ii) wherein the front panel and the back panel each have an inside surface and an outside surface;
- iii) the inside surface of the front panel faces the inside surface of the back panel;
- iv) the front panel and the back panel are joined on three sides, and the fourth side is open;
- b) providing an adhesive composition;
- c) applying the adhesive composition:
- i) to the inside surface of the front panel and the inside surface of the back panel;
- wherein the article can be sealed by a twisting motion that brings the inside surface of the back panel and the inside surface of the front panel into contact that activates the adhesive composition;
- or
- ii) to the outside surface of the front panel and the inside surface of the back panel;
- wherein the article can be sealed by a twisting motion, or a fold over and twisting motion, that brings the outside surface of the front panel and the inside surface of the back panel into contact that activates the adhesive composition;
- or
- iii) to the inside surface of the front panel and the outside surface of the back panel;
- wherein the article can be sealed by a twisting motion, or a fold over and twisting motion, that brings the inside surface of the front panel and the outside surface;
- or
- iv) to the outside surface of the front panel and the outside surface of the back panel;
- wherein the article is inverted (turned inside out) prior to use so that the article can be sealed with a twisting motion that brings the adhesive coated surfaces of the front panel and the back panel into contact that activates the adhesive composition.
