摘要： A method of manufacturing multi-ply tubular containers for food products is provided including the steps of applying an aqueous adhesive to a surface of a paperboard body ply and then heating the aqueous adhesive to evaporate part of the water content and render the adhesive substantially tacky. The body ply and a polymeric liner ply having a moisture barrier layer are then passed through a nip to adhere the liner ply to the body ply and are wrapped around a shaping mandrel to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having a body ply formed of paperboard which is wrapped into a tubular shape to define an inner surface. The body ply defines a predetermined circumferential length before being wrapped which corresponds to one revolution of the body ply when wrapped in a tubular shape. A polymeric liner ply is adhered to the inner surface of the body ply and defines a circumferential length equal to that of the body ply prior to being wrapped. Accordingly, the liner ply is circumferentially compressed when the body ply is wrapped into the tubular shape and advantageously has a wrinkled surface finish after being wrapped which is caused by the circumferential compression of the liner ply.
摘要翻译：提供一种制造用于食品的多层管状容器的方法，包括以下步骤：将水性粘合剂施加到纸板体层的表面，然后加热水性粘合剂以蒸发部分含水量并使粘合剂基本上发粘。然后将身体帘布层和具有防潮层的聚合物衬垫层通过辊隙以将衬垫层粘合到身体帘布层上，并缠绕成形心轴以形成管状容器。因此，可以制造有利的管状容器，其具有由纸板形成的主体层，其被包裹成管状形状以限定内表面。在被包裹之前，身体帘布层限定了预定的圆周长度，其对应于当被包裹成管状形状时对应于身体帘布层的一圈。聚合物衬垫层被粘附到主体帘布层的内表面，并且在包裹之前限定与身体帘布层相同的圆周长度。因此，当主体帘布层被包裹成管状时，衬垫层被周向地压缩，并且由于衬垫层的周向压缩而在包裹之后有利地具有起皱的表面光洁度。

摘要： A method of manufacturing multi-ply tubular containers for food products is provided including the steps of advancing a continuous body ply formed of paperboard towards a shaping mandrel and advancing a continuous polymeric liner ply adjacent to one surface of the paperboard body ply. The polymeric liner ply includes a moisture barrier layer and an adhesive layer defining one surface of the liner ply, wherein the adhesive layer includes a polymeric adhesive which is activated at a predetermined activation temperature. The body ply is heated to a temperature above the activation temperature of the adhesive, and the body ply and the liner ply are then passed in face-to-face contact through a nip to adhere the liner ply to the body ply. The body ply and liner ply are then wrapped around a shaping mandrel to create the tubular container. Accordingly, an advantageous tubular container can be manufactured having an unsupported and polymeric liner ply which is adhered to a body ply without the application of any separate adhesives.
