Abstract: A method of labeling mold cavities in a blow-molding machine using an in-mold labeling system including first and second label magazines, first and second rotary members each having a label transfer unit with a suction cup, and using the steps of rotating each member to position the suction cup adjacent a magazine, transferring a label in the magazine to the cup, rotating the member to position the held label adjacent a pickup position, transferring the label to a suction cup of an in-mold labeling unit and actuating the unit to place the labels in mold cavities of a blow molding machine. When the suction cup of the transfer unit is adjacent the magazine, a high vacuum is drawn to remove one label from the magazine and then the vacuum level is reduced to a low vacuum. During transfer of the label from this suction cup to the suction cup of the labeling unit, the low vacuum is maintained on the transfer unit suction cup while a high vacuum connection is formed between the labeling unit cup and the label.

Abstract: A method of preparing an in-mold label is described in which a resin film is embossed to form a gravure pattern having from 60 to 200 roll-formed lines per inch. The embossed film is stretched and then coated on its embossed pattern side with a heat-sensitive liquid resinous adhesive in an amount of from 1 to 10 g/m.sup.2 on a dry resin basis. The applied adhesive is then dried to form an adhesive layer on the film. The in-mold label obtained by the present invention is excellent in printing suitability including feeding properties and ink adhesion, has an advantage that die-cutting for producing the label can be conducted at a high efficiency, and is less apt to develop blisters even under a wide range of molding conditions when used in in-mold application.

Abstract: A uniaxially oriented coextruded polymeric in-mold label film includes a uniaxially hot-stretched, annealed, linerless self-wound film having a face layer for printing and a base layer which includes a heat-activatable adhesive. The heat-shrinkability of the film is balanced thickness-wise to minimize curl and allow the film to be printed in conventional label-printing presses. An antistat is included only in the charge for the base layer which includes the heat-activatable adhesive. In the manufacture of labelled blow-molded containers, sheets and labels formed from the film may be handled at high speeds while maintaining accurate registration and dimensional and positional integrity even in the absence of any reinforcing backing, yet the labels perform well on deformable containers such as shampoo bottles.

The top sheet is adhered to the base sheet by a dry residue adhesive in a manner which allows uniform and simultaneous shrinkage to occur between the base sheet and the top sheet as the molded container cools and shrinks, while also allowing subsequent removal of the top sheet from the base sheet, leaving a nontacky and visually unobstructed base sheet and removed section of the top sheet.

Abstract: In a hollow molded container equipped with a label and its production method, molding is made by use of a label consisting, as a base, of a stretched film of a plastic having a thermal shrinkage ratio greater than a mold shrinkage ratio of a plastic constituting the outer surface of a container, at a temperature 40.degree. C. lower than the melting point or softening point of the plastic so that the label is bonded to the container at a residual equilibrium shrinkage ratio (Rs), defined below, of 0.5 to 100%: Rs=L.sub.1 -L.sub.2 /L.sub.1, where L.sub.1 is a length of a label film peeled from the container and L.sub.2 is a length when the peeled label film is brought to equilibrium at the temperature (T.sub.1) described above. In this manner, crease and swelling of the label during labelling operation inside the mold can be prevented and adhesion and peel-resistance between the label and the container outer surface can be improved.

Abstract: This relates to a labeller for applying simultaneously two labels to a dual cavity mold half. The labeller is especially constructed to receive a pair of labels from a pair of adjacent label magazines and then move one of the labels towards the other so as to reduce the overall width of the pair of labels.
