20080302067 | Easy-opening ream wrap - A protective wrap material enclosing a stack of cut sheets of paper is folded so that overlapping flaps of the wrap material cover opposite ends of the stack. The overlapping flaps are secured and sealed together only at selected areas that comprise a minor portion of the overlapped flaps, wherein the sealed areas have sufficient burst strength to avoid inadvertent opening of the wrap but at the same time are relatively easy to separate when it is desired to open the wrap to gain access to the cut sheets of paper. In a preferred embodiment the wrap material is heat sealable, and a modified heat plate for applying heat only to the selected areas has a grooved front surface defining heat focusing bars that concentrate heat sufficient to fuse the wrap material only in the selected areas. | 12-11-2008 |
20090183469 | REAM OF PAPER HAVING HEAT SEALABLE WRAPPER - The wrapper for a ream of paper has an inner surface coated with polyethylene. When the wrapper is formed about a ream of paper, the inner layer overlaps and contacts the outer layer along a longitudinal seam. The polyethylene layer is used to create a seal with the application of heat. Areas of the inner surface in proximity to a heat source during the heat sealing process and where a seal will not be beneficial are covered with a heat shield, such as a varnish. In this way, damage to the paper is avoided. The varnish includes Styrenated Acrylic polymer, with Kaolin Clay and ink. The varnish is applied to the wrapper during the same manufacturing process as the polyethylene coating. | 07-23-2009 |

20100037564 | FLAT PANEL DISPLAY PACKAGE METHOD - The present invention discloses a flat panel display package method. Firstly, a flat panel display and an electronic baseplate are prepared; the electronic baseplate is assembled to the flat panel display to provide a driving signal for the flat panel display and form a display module, and the display module defines a module package plane. Next, a first package film and a second package film are respectively provided for the flat panel display and electronic baseplate; the first package film and the second package film both outside the module package plane are respectively defined to be a first join region and a second join region. Next, a hot-pressing machine is used to apply a hot-pressing temperature and a hot-pressing pressure to the first and second join regions and seal them airtightly. Thereby, the present invention can prevent external humidity entering and damaging the flat panel display and the electronic baseplate. | 02-18-2010 |

20150089905 | THERMO-SEALING CONTROL METHOD AND PACKAGING FOR RESEALABLE PACKAGING - A packaging and method for controlling the seal strength between two cooperating thermo-sealable films at predetermined sealing portions, where a predetermined amount of heat is applied over a predetermined period of time. The resulting packaging is resealable after the first separation of two surfaces. The strength of the seal controlled by defining the number and dimensions of a plurality of restricted areas without a material cover that is resistant to the thermo-seal effect. The restricted area can be defined with a plurality of dots of predetermined selected shapes and dimensions. The resulting article facilitates the rupture of the packaging along a predetermined path. With this process, a fixed predetermined heat and residency time can be chosen and the seal strength can still be varied in different areas of a packaging. Non-sealable microdots with a predetermined amount of adhesive deposits also covered by a polypropylene powder deposit permit its resealing. | 04-02-2015 |
