FOERPACKNINGSBEHAOLLARE MED OEPPNINGSBAR, FOERSEGLINGSFOERSVAGAD TOPPFOERSLUTNING. |
摘要 |
<p>A packing container (2) comprising a container body consisting of side walls (3,4) which has been given an arbitrary bottom closure (5) and which at the top has been closed by bellow-type folding and heat sealing so as to form a top closure of the gable-top type which can be unfolded to an emptying opening (25) in the form of a pouring spout. To facilitate this re-unfolding certain portions (the areas C and D) of the surfaces which are heat-sealed to one another are coated within the area of the unfoldable part of the top closure with a seal-weakening composition which is based on an aqueous dispersion of a thermoplastics, preferably polythene, which is modified by a carboxymethyl cellulose, preferably sodium carboxymethyl cellulose.</p> |
