Definitions

  • This invention relates to self adhesive labels and in particular concerns labels which are supplied in roll form.
  • the labels will mainly be for application, using suitable machinery, to individual articles or objects.
  • Pressure sensitive labels find wide application in the field of produce marketing because because, for example, in supermarkets and other stores the products on sale are typically priced by means of a small pressure sensitivee label which is applied to the product, and frequently these labels have to be changed because of price change, making consumption of the label enormous.
  • pressure sensitive labels are mounted on a carrier or backing web which is normally a web of paper coated with a suitable release material such as a silicone compound.
  • the adhesive labels are applied to this carrier or backing web for transportion, storage and utilisation, but the labels can readily be peeled from the backing web as there is a much stronger bond between the adhesive and the material of the label, than between the adhesive and the release material.
  • U.K. Patent Application 2,013,613 also discloses that it is known to provide a roll of labels, and on one side of the web is pressure sensitive adhesive whilst on the other side is a release coating to enable the web to be wound into roll form without the use of a backing strip.
  • the roll of labels is placed in a "labelling gun" to enable the feeding of the web to unroll same, and the severing of individual labels from the roll by transverse cutting thereof.
  • No detailed description is given of how the labelling gun operates, but such guns are probably small hand carried items as they are described as being of a type which are carried by clerks to enable the prices of goods to be marked on the goods by application of the labels thereto.
  • This specification as the United States patent 2,845,728 is therefore more concerned with the provision of small price labels as opposed to the somewhat larger labels which are applied to articles such as bottles and cans.
  • the invention provides a roll of self adhesive labels for the application of the labels individually to articles which are moved one by one relative to the station at which the labels are applied.
  • self adhesive label stock material which is wound into roll form and can be unwound for use comprising a substrate label web which on one side is printed with repeating and equally pitched label information so that individual labels can be taken therefrom and applied to products, and having sprocket holes for engagement with a sprocket member as the substrate passes through applicator apparatus, said holes being pitched in register with the pitching of the printing, a self adhesive coating covering only a fraction of the whole of the surface area of one side of the substrate to increase the ease with which the labels can be applied to the products, and wherein there is a release surface which contacts the other side of the adhesive when the stock material is in roll form ensuring that the adhesive will remain adhered to the substrate web when the material is unrolled.
  • a non-porous web is used for the label strike and the release characteristic is provided by applying a curable release coating to the non-adhesive side of the web and the release coating is applied in relatively small amounts, which means that the curing time for the release coating is reduced, and lower curing temperatures (as compared to the curing temperatures used in U.S. Patent No. 3,575,788) can be used for the curing. Moreover, it is not necessary to apply a nitrocellulose base ink to the web before application of the release coating.
  • the web is preferably of a relatively non-extensible material so as to enable the individual labels to be cut therefrom.
  • the web may be die cut to define individual labels therein and the release coating is supplied over the cuts to provide extra retention strength holding the labels together or to the remainder of the web, or the labels may be such that they are cut totally from the web at the time of application to the articles.
  • the web may be printed to define the labels, the printing being on the side of the web to which the release coating is applied.
  • the web is of a synthetic resinous material containing an inorganic filler such as talc or chalk.
  • the web material defining the labels may be of a thickness consistent with the thickness of the labels as conventionally used.
  • the labels which are defined in the web and are removable fiom the web to leave a skeletal waste
  • the said labels are defined by perforations, there may be such as to leave sufficient "catchpoints" between the label and the remainder of the web so that the label will remain in position in the web until such times as it is forceably removed or displaced therefrom.
  • the leading edge of the label, which is first attached to the product or article may be free of such catch points so that it will deflect readily out of the web to simplify application.
  • the release coating may be applied to the web by rollers, gravure cylinders or hot melt applicators to provide a surface having a release characteristic.
  • the coating may for example contain non-migrant repellants, and in particular, polymerisable silicone polymers.
  • the coating may for example be a solvent heat cured coating, an aqueous system, solvent free or UV cured, examples of the above are as follows:
  • Silcolease * (TM) 425 (30%) (ICI) 100 parts by weight Catalyst 62A (ICI) 4 parts by weight Catalyst 62B (ICI) 4 parts by weight Toluene 200 parts by weight Curing Time at 120°C 10 seconds 100°C 15 seconds 90o C 20 seconds Dry off solvent prior to cure approx. 5 seconds.
  • Bath 1 Standard bath for in-line use or off-line on certain substrates such as PEK.
  • Bath 3 Special low solids bath for coating films such as polyethylene. Solvent choice important and ethyl acetate best. Uses Q2-7127 as accelerator.
  • Bath_5 - Premium release formulation involving incorporation Q2-7090 low viscosity fluid and additional Q2-7127 to restore catalyst level.
  • Bath 1 and 2 cure in 8-12 seconds at 140°C depending on substrate nature.
  • Bath 3 will cure in 15-20 seconds at 70°C.
  • Bath 4 cures typically in 15 seconds at 140 o C.
  • Bath 5 cures in 30 seconds at 100°C or 10 seconds at 140°C.
  • C.M.C. Carboxy methyl cellulose 2 parts by weight.
  • the amount of release coating applied may be in the order of 0.1 to 1.5 grams/sq. metre depending upon the web.
  • the pressure sensitive adhesive may be applied by conventional means, and typicallay may be a solvent or water based emulsion of which the solvent or water is dried from the web after application.
  • the pressure sensitive adhesive may for example be hot melt, water based, or solvent based, examples of which are as follows:
  • Elvax * 40-P (Du Pont) (Ethylene-vinyl acetate resin) - 40 parts by weight.
  • Piccovar * L-60 Hercules Inc.
  • Hydrocarbon resin Hydrocarbon resin
  • Irganox * 1010 (Ciba Geigy) (Antioxidant) - 0.5 parts by weight.
  • the labels may be colour printed by any suitable method such as letter press, flexographic, gravure or offset litho.
  • polypropylene or high density polyethylene film including substantial proportions of particulate inorganic material.
  • the inorganic material may be included in the range 20 to 50% of the web by volume, and in the preferred case the web is polypropylene ethylene sequential copolymer, as described in our British Patent No. (1544,143) filled with 40% talc.
  • Fig. 1 there is shown a web 10 having perforations 12 defining individual labels 14, each provided with printing 16.
  • Catchpoints 18 serve to hold the labels to the remainder of the web 10, but the catchpoints can be burst or cut to enable removal of labels 14 leaving a residual skeletal waste.
  • the web 10 is made up of a central substrate web 20 which is of a non-fibrous and substantially inextensible material and on one side of which is applied a pressure sensitive adhesive coating and on the other side is applied a release coating 22, and on the other side is applied a release coating 24.
  • the web is shown in greatly enlarged dimension in Fig. 2, to illustrate the slits 12 and also to illustrate how the coating materials 22 and 24 migrate into the said slits 12.
  • the substrate 20, adhesive coating 22 and release coating 24 are of a nature as described herein, and the web is wound so that the adhesive coating 22 is to the inner side of each coil and contacts directly on the release coating 24 of the adjacent inner coil. This arrangement enables the web to be easily unrolled.
  • the web may be wound on a suitable core 26.
  • the printing 16 (single or multi coloured and of any desired pattern and/or content) is applied to the substrate 20 prior to the appliation of the coating 24, and in addition the perforations or slits 12 are formed prior to the application of the said coating 24.
  • the coating 24 in fact has the effect of assisting the holding of the labels 14 in position in the web until they are removed for application to articles.
  • the coating 24 also serves the purpose of preventing migration of the adhesive 22 through the slits 12 when the web is wound on core 26. This tendency to migrate will depend upon how tightly the roll is wound on core 26.
  • Fig. 3 illustrates diagrammatically how the individual labels 14 may be removed from the web 10 and applied to can bodies such as can body 28.
  • the web 10 is shown as travelling round a guide drum 30 in the direction of arrow 32, with the pressure sensitive adhesive coating side outermost.
  • Each can 28 to be labelled comes ianto contact with the pressure sensitive side of the web 10, and a label 14 is removed from the web 10 and applied to the can body 28, as shown in Fig. 4.
  • the web 10 has sprocket holes at each side thereof which will be arranged by suitable sprocket wheels or rollers and the web will be indexed forwards towards the product to be labelled.
  • the leading edge of the label having regard to its direction of movement (arrows 32), can be released from the web by a suitable knife or by virtue of changing the direction of movement of the web sharply.
  • the contact pressure between the pressure sensitive surface and the product being labelled can be used to effect or assist the complete removal of the label from the web. The removal may if necessary be assisted by severing the remaining catchpoints 18 by means of suitable knives positioned appropriately.
  • the skeletal waste of the web 10 may be wound up into a suitable coil for disposal.
  • a web 10 carries printing 16 which repeats at pitch length P, but the web has no perforations or lines of weakening.
  • the web def ines labels which have to be cut from the web by suitable cutting equipment located in the region of the application head 36 so that individual labels are cut from the web immediately prior to or during application of the label to the article 28 to which the label is being applied.
  • the adhesive covers only a fraction of the web surface at one side, to increase the ease with which the labels can be applied to the products and to limit extrusion of the adhesive out of the side of the roll of labels.
  • Fig. 6 shows in somewhat greater detail, how labels in roll form as shown in Fig. 1 may be applied to box shaped products 40.
  • the roll of labels is indicated by numeral 42 and is unwound from this roll by a tractor unit 44 having a suitable sprocket feed device which engages the holes in the margins of the web 10 (the said holes are not shown in the drawings) and is fed through a removal and application station 46.
  • the skeletal residue of the web 10 is wound into roll form as shown by numeral 48.
  • the adhesive side of the web 10 is the upper side and all surfaces which contact this adhesive side are required to be of a nature so as not to adhere to the adhesive. Such surfaces may be defined by silicone release material.
