摘要： A paperboard product having at least one layer of bleached or semi-bleached pulp and having improved smoothness and reduced bulk loss. For paperboard having sizing without pigment, the smoothness on the printed side, measured by the Parker test is better (lower) than 6.5 when measured using a pressure of 10 kgf/cm2 while the smoothness measured by the Hagerty/Sheffield test is not below 280 Sheffield units. For paperboard having sizing with pigment, the Parker smoothness is less than 5.0 and the Hagerty/Sheffield smoothness is not less than 180 Sheffield units. The web is finished by applying temperature and moisture gradients, then smoothing the web surface using extended nip calendering. The surface temperature of the calendering roll is maintained at 250-400° F. Prior to entering the extended nip, the web surface is moisturized using steam showers. The nipload applied in the heated extended nip is preferably between 300 to 2,500 pli.
摘要翻译：一种纸板产品，其具有至少一层漂白或半漂白纸浆并具有改善的平滑度和减少的体积损失。对于没有颜料的尺寸的纸板，当使用10kgf / cm 2的压力测量时，通过Parker测试测量的印刷面上的平滑度优于6.5，而通过Hagerty / Sheffield测试测量的平滑度不低于280 谢菲尔德单位。对于具有颜料尺寸的纸板，Parker平滑度小于5.0，Hagerty / Sheffield平滑度不低于180谢菲尔德单位。通过施加温度和湿度梯度来完成幅材，然后使用延长的压区压光来平整纸幅表面。压延辊的表面温度保持在250-400°F。在进入延伸压区之前，使用蒸汽淋浴来对网表面进行增湿。施加在加热的延伸辊隙中的夹紧压力优选在300至2,500pli之间。

摘要： The invention provides a low density paperboard material and associated method for use in producing an insulated container, and is especially well-suited for making cups. The paperboard material comprises a paperboard web including wood fibers and expanded microspheres, and has a relatively low density ranging from about 6 to about 10 lb/3 MSF/mil, a relatively high caliper ranging from about 24 to about 35 mil, and an internal bond strength of at least about 80×10−3 ft-lbf., preferably at least 100×10−3 lft-lbf. For applications such as cups the material is also coated on one or both sides with a barrier coating, preferably low density polyethylene, to limit liquid penetration into the web. The low density paperboard material of the invention is convertible for manufacture of containers, particularly cups, and exhibits insulative properties comparable to higher cost materials conventionally used to make cups. Also, the surface of the low density board may have a Sheffield smoothness of 300 SU or greater compared with the surface smoothness of 160 to 200 SU for conventional cupstock, the latter having been thought necessary for adequate print quality. However, it has been found that the low density board exhibits good printability on flexo printing machines despite its relatively rough surface, which is surprising and bonus effect realized along with the insulative and other properties of the board.
摘要翻译：本发明提供一种用于制造隔热容器的低密度纸板材料和相关方法，特别适合于制造杯子。纸板材料包括包含木纤维和膨胀微球体的纸板网，并且具有约6至约10lb / 3 MSF / mil的相对较低的密度，约24至约35密耳的相对较高的卡尺，以及内部粘合强度为至少约80×10 -3 ft-lbf，优选至少100×10 -3ft-lbf。对于诸如杯子的应用，材料也在一侧或两侧上涂覆有阻隔涂层，优选低密度聚乙烯，以限制液体渗透到网中。本发明的低密度纸板材料可转换用于制造容器，特别是杯子，并具有与常规用于制造杯子的较高成本材料相当的绝缘性能。此外，低密度板的表面可以具有300SU或更大的谢菲尔德平滑度，与常规杯状物的160至200SU的表面平滑度相比，后者被认为对于足够的打印质量是必要的。然而，已经发现低密度板在柔版印刷机上表现出良好的印刷性，尽管其表面相对粗糙，这与板的绝缘性和其它性能一起实现了令人惊奇的效果。
