    摘要: A magnetically resealable bag including a polymer substrate. The polymer substrate including a front panel, a back panel, a closed bottom and an opening. The inside of the opening including a first side strip and a second side strip. The first side strip and second side strip include a layer of a magnetizable composition, and at least one layer of a polymer material arranged to provide a covering over the layer of the magnetizable composition. A top portion of the first side strip is coupled to the inside at the front panel of the bag and a top portion of the second side strip is coupled to the inside of the back panel of the bag, and a bottom portion of the first and second side strip is free of the inside of the opening. The first side strip and second side strip are aligned and permanently magnetized.

    摘要: A magnetic roller may comprise a magnetized outer surface and an internal chamber. A temperature control system may be in communication with the internal chamber, and a fluid capable of heat transfer may circulate within the internal chamber and the temperature control system. The magnetic roller may be used to produce magnetic sheets having magnetizable particles that are aligned according the a magnetic field generated by the magnetic roller. The magnetic sheet may be provided in a pliable form wherein magnetizable particles may shift orientation when exposed to the magnetic field. Heat may be transferred between the sheet and the magnetic roller to cause solidification of the magnetic material and prevent dealignment of the magnetic particles.
