Abstract: The process for applying labels to articles by first adhering a limited portion of the label to the article and subsequently rendering additional portions of the label adhesive so that they will adhere to the article after the label is affixed to the article. The leading and trailing edges of the label may be bonded to the article or each other to affix the label to a container or other such article. The portions of the label between the leading and trailing edges may be either provided with an adhesive agent that is in a non-adhesive state or be formed from a label material which is not normally adhesive but can be rendered adhesive through an additional process step. For example, coated polyethylene film can be applied to a container by means of a hot melt adhesive and then subsequently heated to a temperature at which the polyethylene material becomes adhesive causing it to stick to the container.

The heat shrinkable materials used for the roll covers include only ultra high melt viscosity polymers, having a melt viscosity too high for conventional melt processing, such as TFM and UHMWPE, rather than the conventional FEP or PFA.

Abstract: A structure is defined for supplying heat shrinkable labels to a labeling machine. Two elongated webs of a heat shrinkable laminate are provided having a continuous series of printed labels positioned end to end thereon. A clear heat shrinkable splice, having an adhesive on one surface, is used to secure the ends of the two webs such that they are positioned adjacent one another and such that they form a single continuous web. The material of the labels and the material of the splice have substantially equivalent shrinkage values such that, upon application of heat to the label and splice within the label machine, the label shrinks along with the splice without causing substantial distortion to the printing on the label. Because the splice is clear or transparent, it can be positioned on the outside of the label, over the printing without obliterating same.

Abstract: Heat-shrinkable thermoplastic resin films suitable for use as labels on the bottles, particularly as full labels on the PET bottles, wherein the heat shrinkability in the main shrinkage direction of the film is 5% to 60% after treatment in hot water at 70° C. for 5 seconds and 67% or higher after treatment in hot water at 85° C. for 5 seconds and the heat shrinkability in a direction perpendicular to the main shrinkage direction of the film is 10% or lower after treatment in hot water at 85° C. for 5 seconds. When used as full labels on the bottles, these films can have good shrinkage finish because they cause only rare occurrence of wrinkles, shrinkage spots, and strains during heat shrinkage, and they are therefore extremely useful as full labels.

Abstract: A method for forming a balloon for a dilatation catheter may utilize the steps of extruding a tubing preform of a polyester resin and then blowing the tubing into an oriented balloon, wherein the tubing preform is dried prior to blowing into the balloon form. Other process steps by which balloon cone and waist thicknesses may be reduced involve varying the axial tension and blowing pressure at several stages as a mold containing the balloon preform is dipped into a heating medium. Specifically, tubing of a thermoplastic material is placed in a mold and blown by pressurizing and tensioning the tubing and gradually dipping the mold into a heated heat transfer media so as to sequentially blow a first waist, a body and a second waist portion. The tubing is subjected to a relatively lower pressure while the body portion is blown than while the first and second waist portions are blown.

Abstract: A low odor grip is disclosed for a handle of a hand-held implement such as a sports implement or a manual or electric tool which is essentially free of disagreeable odors, which can be installed and quickly shrunk into a tight vapor resistant grip within a matter of a few minutes rather than requiring extended periods of time, and can be installed without the need for any application of heat or use of special tools, equipment or materials. The present device is therefore easy to install, merely sliding over the handle while in dilated state and then allowed to shrink and set by evaporation of the solvent, and thus can be satisfactorily installed in both fabrication facilities and in the field either as an original or replacement grip. The invention also includes an implement fitted with such grip. Representative implements include sports implements such as golf clubs, tennis racquets, weight bars and fishing poles, as well as tools such as hammers, drills, pliers, shovels, axes, and the like.
