[0067] Various samples of printable laminates according to the present subject matter were prepared and evaluated. The evaluation results are as follows.
[0068] printing test method
[0069] The printability of the samples was evaluated using a wide format high boiling point polar solvent inkjet printer and a desktop water based inkjet printer.
[0070] When using a polar solvent based inkjet printer to evaluate media printability, a wide format Eco-Solvent inkjet printer Roland Soljet Pro II XC-540 printer equipped with Eco-SolMax inkjet (available from the Roland Company) was used Printing is performed on the surface film. Using AVERY MPI1005SC ICC mode, print image files with graphics and color bleeding patterns on the surface film to check the image quality and resolution. The temperature control settings of the printer are: preheating 40°C / printer heating 40°C / dryer heating 50°C. When the printed matter has just left the heated bed of the printer, use a pressure rol...
Embodiment A
[0077] Monolayer porous polyethylene (PE) films with different draw ratios were prepared as follows: Mixing 75% CaCO 3 / LDPE masterbatch resin pellets (Colortech 40002-08, with 75% CaCO 3 and 25% masterbatch of LDPE, density = 1.82) and 25% LLDPE resin pellets (Dowlex 2056G; MI = 1.0, density = 0.92). The total proportion of CaCO in the blend resin is 56% 3 and a PE of 44%. The resin pellet blend was added to extruders A, B, C and D. The extruder temperature was set at 420°F. Casting rolls and MDO rolls are set at T = 120°F for both casting rolls; preheat rolls 1, 2, 3, 4, 5 are set at T = 195°F; draw rolls 1, 2 are set at T = 185°F; anneal rolls 1 and 2 were set at T = 195°F; and chill rolls were set at T = 70°F. In order to prepare film samples with different stretching ratios, the stretching ratios of stretching roll 1 and stretching roll 2 were set to 1:1, 1:2, 1:3, 1:3, 1:3.5 for each sample , 1:4.5, 1:5. The corresponding samples collected were labeled samples A-...
Embodiment B
[0082] Monolayer porous polypropylene (PP) films with different draw ratios were prepared as follows: 80% CaCO 3 / PP masterbatch resin pellets (Ampacet 103211CaCO 3 , Ampacet CaCO 3 / PP masterbatch with 70% CaCO 3 , density=1.70) and 20% PP resin pellets (Flint Hill HPP, P4G3Z-050F; MFR=4.2, density=0.9) were mixed. The total proportion of CaCO in the blend resin is 56% 3 and 44% PP. The resin pellet blend was added to extruders A, B, C and D. The extruder temperature was set at 460°F. Casting rolls and MDO rolls are set at T = 120°F for both casting rolls; preheat rolls 1, 2, 3, 4, 5 are set at T = 230°F; draw rolls 1, 2 are set at T = 230°F; anneal rolls 1 and 2 were set at T = 230°F; and chill rolls were set at T = 70°F. In order to prepare film samples with different stretching ratios, the stretching ratios of stretching roll 1 and stretching roll 2 were set to 1:1, 1:2, 1:3, 1:4, 1:4.8 for each sample , 1:5. After stretching 4.8× and above, the bands disappear. ...
