<p>PURPOSE:To produce an easily disposable bag or container using cellulose fiber suitable for the solution of environmental problems by a method wherein the sheet having at least one side consisting of cellulose fiber is heat sealed via a heat-sealable fiber, etc. CONSTITUTION:A sheet is formed of cellulose fiber such as cotton, jute and pulp alone or in combination thereof such as cotton-jute and cotton-pulp blend and is heat sealed via heat-sealable fiber or tape, whereby a bag or container is produced. During this time, a heat-sealable and biodegradable substance may be used as a binder. To make a tea bag, for example, the sheet 1 is formed of the nonwoven fabric obtained by enveloping cotton web by water needle method and folded back and polyethylene yarn is then interposed between the overlapping parts 5 and 6 of the left side 4 and heat sealed thereto.</p> |
