PLASTIC BAG WITH PRINTABLE INNER FACE

Plastična kesa (1) sa najmanje dva šavovima (4 i 12) povezana zida (2, 3) od polietilenske monofolije ili neke folije u sloju sa polietilenskim slojem na unutrašnjoj strani kese (1), pri čemu je unutrašnja strana korona-tretmanom ili tome sličnom postupku štamparskog predtretmana površine promenjena radi bolje sposobnosti štampanja, naznačena time, što je najmanje jedan šav između štamparski predtretiranih unutrašnjih strana (2, 3) napravljen kao zatopljeni šav (12) sa međuslojem (14) kao folijom od površinski nepromenjenog poliolefina, čija tačka topljenja ne leži iznad tačke topljenja folije plastične kese.Prijava sadrži još 7 patentnih zahteva. The invention relates to a plastic bag (1) with at least two walls (2, 3) which are connected by seams (4, 12) and which are made of a polyethylene monofilm or a layered film with a polyethylene layer on the inner face of the bag (1). The inner face is modified by a corona treatment or a similar printing pretreatment of the surface in order to improve the printability. The bag is designed to be usable with respect to the problematic heat sealability of printing-pretreated polyethylene surfaces to one another for the purpose of a machine-adapted processing with quick work cycles, such as the processing which is already used for unpretreated surfaces, by forming at least one seam between the pressure-pretreated inner faces of the walls (2, 3) as a sealing seam (12) with an intermediate layer (14) as a film made of a polyolefin which is not modified in the surface and the melting point of which does not lie above the melting point of the film of the plastic bag.
