Abstract: A method useful for applying labels to a container, the labels having an activatable adhesive coating on a surface thereon, the adhesive is activated by contact with a low viscosity activator solution from an apparatus comprising at least a label pallet that receives a low viscosity activator solution by contact with a spinning roller, the spinning roller receives at least one stream of the low viscosity activator solution delivered or sprayed by a fluid manifold.

Abstract: This disclosure relates to a package and a method of making the package. The package comprises (a) a web material to form an enclosed package comprising a seal having two seal ends and a package side edge, and wherein the seal is a fin seal or an overlap seal; (b) a first tear initiation point located on the package side edge; and (c) a second tear initiation point, wherein the second tear initiation point is located on the seal.

Abstract: Multi-layer films particularly suited for packaging applications, including a core layer, a tie layer made from at least 10 wt % of a first polymer and a service layer, wherein the tie layer is a sealable layer and may provide a hermetic seal when sealed to itself. The films of this invention may be suitable for use in preparing hermetically sealed packages. Optionally, the multi-layer film may have a skin layer and/or a second skin layer. Embodiments may have the advantage of improved seal strength, hermeticity, hot tack, reduced-temperature sealability, and improved packaging machine operating speed.

Abstract: A lamination structure comprises a first layer bonded to a second layer. The first layer is bonded to the second layer by a destruct bond with a starch adhesive. The first layer may be a flat layer or a fluted layer and the second layer may be a flat or fluted layer. At least one surface of the first layer and/or the second layer, which is bonded to the other layer, is the surface of a thermoplastic film. The thermoplastic film is treated or coated in a manner sufficient to permit the surface or surfaces to form the above-mentioned destruct bond, using a starch adhesive. An example of a surface treatment is flame treatment. An example of a coating is an acrylic coating.

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.

Abstract: Multilayer, generally three layer films, with non-migratory slip agents in a skin or outer layer of the multilayer films are contemplated. The films may be metallized. The particle size of the non-migratory slip will generally be equal to or larger than the thickness of the skin layer of which they are a part. The films will generally be oriented, usually biaxially oriented.

Abstract: A multi-layer film has an improved composite structure for providing hermetic seals to packages manufactured in high speed packaging apparatus. The structure of the multi-layer film includes layers A/B/C/D. Skin layer A is formed from polypropylene copolymer with melt flow rate greater than one or linear high density polyethylene with melt index greater than one. Core layer B is formed from polypropylene. Intermediate layer C has the primary function of compliance during sealing, and sealing layer D has the primary function of providing adhesivity to the completed seal.
