| titleOfInvention | Polymeric cellulosic seal for sealing tinplate |
| abstract | polymeric cellulosic seal for sealing tinplate. the present invention belongs to the technological sector of coating for packaging and refers, more specifically, to the composition of flexible laminated film for making a polymeric cellulosic seal for stamping and thermo-sealing on tin plates, which, as a result of the elimination of aluminum plates of its composition, significantly reduces the costs arising from previous treatments for the preparation of tin plates, in addition to being more ecological and safer than other technologies and formulations available in the state of the art. the composition now disclosed consists of white paper (a), adhesive (b), polyester (c), aluminum (d), anchoring primer of thermosealer (e) and thermosealer (f), combined in specific proportions, which result in a low molecular density of the laminated film (1.3458 g/cm³), causing a consumption of material per package of 114.4 g/m², which results in a yield 31.08% higher than that obtained in the traditional method, which uses aluminum sheets and preparation by means of chemical sealant, presenting high molecular weight with density of 2.7 g/cm³, and high consumption of material per package (166 g/m²), when compared to the formulation proposed herein. |
