FIELD: process engineering. ^ SUBSTANCE: invention relates to production of plastic bags. Proposed method comprises preparation of endless film and webs, applying glue and extra adhesive on one of opposite surface of said film or endless web. Then said web is arranged opposite endless strip to press it there against. Note here that strong adhesive and extra adhesive are arranged there between. Said strip and web are temporarily fixed relative to each other by extra adhesive since string glue requires time for hardening. Hardened film is fed into plant continuously forming plastic bags. Every plastic bag comprises definite section formed from endless film that has outer surface to make handle from strip. ^ EFFECT: higher efficiency. ^ 2 cl |
