    Abstract: A solvent-based adhesive is used to form a continuous, adhesively bonded and welded seam at the longitudinal edge portions of plastic film which have been overlapped. First, a bead of the adhesive is disposed on the edge portion of a web of film passing over an applicator roll. Next, as the film moves between the applicator roll and nip rolls, the adhesive dissolves a portion of the film to form a longitudinal channel having a generally semicircular cross-section. Then the edge portion is overlapped onto the other edge portion with the bead of adhesive between them. Finally the overlapped edge portions are squeezed between the nip rolls, so that the adhesive exudes laterally outward from the groove and is distributed smoothly between the overlapped edge portions, until the adhesive and dissolved film form a uniform band having a rounded hat-shaped cross-sectional profile.

  • Patent number: 6612356
    Abstract: A back-up pad is provided over an anvil surface of a back-up plate, and between the anvil surface and a sealing surface of a sealing die, in an apparatus for forming seals between layers of film material. The back-up pad has a slip layer on one side thereof and a firm polymeric support layer on an opposite side thereof, the slip layer opposing the sealing face of the die so that the layers of film material pass between the sealing die and the back-up pad during seal formation. The polymeric support layer may have a Shore-A hardness of at least 10 at 20° C. and a dynamic loss tangent of less than 0.1 from 20° C. to 80° C. An example of a support layer is a polycarbonate pad, and an example of slip layer is a glass cloth coated with Teflon™. The back-up pad is particularly useful for forming lap seals in relatively thick film materials, such as laminated films having multi-layered films laminated together.

  • Publication number: 20020124940
    Abstract: A method for manufacturing a label cover with joint lines positioned along folding traces of a lateral side of the label is disclosed. A tubular heat contracting film is printed with various patterns and characters, and then the film is folded as a tubular label cover by a folding machine. One opening of the label cover is placed on a guide plate. The orientation between inlet end and the outlet end of the guide plate is adjustable. After the label cover passes through the guide plate, the position of the joint line is converted to the folding trace of the lateral side of the label cover. By the design of the inlet end and the outlet end of the guide plate, the respective angle after being folded is adjusted so that the overlapping portion of the joint line and the folding trace on the label cover is changed as desired. Therefore, the pattern and characters on the label cover are retained as original forms without being destroyed by the joint line.
