Definitions
- the present invention relates to a composite plastics film or sheet having an external printable surface, for example a synthetic paper.
- this invention relates to an improved synthetic paper suitable for use in in-mould labelling (HVEL).
- plastics sheet is used herein and throughout the specification to mean plastics film and sheet products having a feel and printability similar to cellulose paper. It has been recognised that plastics sheet of these types can provide an improved alternative to paper where durability and toughness are required. Plastics sheets produced from polyolefins have several advantages over other plastics since they offer UN resistance, good tear strength and the ability to be recycled in many post-consumer waste applications.
- Synthetic papers have been produced commercially by the plastics industry for many years and have taken a number of different forms. They have included products having voided (i.e. multicellular) or unvoided structures.
- Plastics substrates are generally impervious to materials such as printing inks. Thus, they tend to be unsuitable for direct use in ink-based printing processes because the ink has a tendency to remain at the surface of the substrate, without being absorbed. It is well known to modify the surface characteristics of a plastics substrate by applying an absorbent coating composition to the substrate's surface.
- the coating composition comprises an absorbent filler, which renders the substrate more absorbent to ink, and a polymeric binder, which binds the filler to the substrate's surface.
- Synthetic papers and their method of preparation have been described in, for example, GB 1470372A and EP 703071 A. These materials are commonly used for the production of labels for in-mould labelling (EVIL) processes, where a label is incorporated inside the mould in which a blow-moulded plastics article is to be blown. The label adheres to the plastic surface during blow-moulding, thereby providing a more strongly bonded and integral label than can be achieved by attaching a label to a finished article.
- the material which may have an absorbent coating on one or both sides of a base layer, is printed on one side and also has to be processed to have a heat- activated adhesive coated on to the second side.
- This adhesive is used to give a strong adhesion between the label and the container to which it is being attached.
- another requirement for the IML process is that the labels, once attached, are substantially free from blistering, which is caused by air being trapped between the label and the surface of the article during the blow-moulding process. Without adhesive, adhesion of the label is poor, and substantial blistering is frequently encountered. Blistering can be minimised by embossing the adhesive on the surface of the label.
- one aspect of the present invention provides a composite plastics sheet which is printable on at least one surface, and comprises a base layer, typically of polyolefinic material, and optionally a printable layer forming the printable surface, characterised in that the base layer has a density of 0.65g/cm 3 or less, or, if there is no separate adhesive layer on the surface opposite the printable surface, a density of 0.7g/cm 3 or less.
- the composite plastics sheet is suitably a synthetic paper.
- the synthetic paper comprises a base layer and a printable surface.
- the base layer comprises a core layer and any co- extruded layer or layers.
- the surface of the base layer may itself be printable, or a printable surface may be added as an additional printable coating.
- a typical density range for the base layer is from 0.3 to 0.65 g/cm 3 , preferably 0.45 to 0.65 g/cm 3 and more preferably 0.55 to 0.65 g/cm 3 .
- a further aspect of the invention provides a blow-moulded article having a label attached thereto by in-mould labelling, wherein the label comprises a composite plastics sheet as defined above.
- the sheet of the present invention may be formed in a known manner, either:
- the composite plastics sheet of the invention comprises a core layer of voided, biaxially orientated polyolefin sheet, having on one side a co-extruded surface layer selected to provide good heat-seal adhesion to blow-moulded bottles, typically high density polyethylene (HDPE) bottles, and on the opposite side a surface coating of an absorbent material suitable for printing thereupon.
- a core layer of voided, biaxially orientated polyolefin sheet having on one side a co-extruded surface layer selected to provide good heat-seal adhesion to blow-moulded bottles, typically high density polyethylene (HDPE) bottles, and on the opposite side a surface coating of an absorbent material suitable for printing thereupon.
- HDPE high density polyethylene
- the core layer comprising polyolefins, filler and the voiding agent may have other components therein such as pigments, other fillers, rubbers and the like.
- the core layer may be of any composition such as is described in our prior published EP-A- 863177, GB-A-1470372 and GB-A-1492771.
- a synthetic paper comprises high density polyethylene.
- high density polyethylene as used throughout the specification is meant to include, unless otherwise specified, polymers and copolymers of ethylene with minor amounts of other ⁇ -olefin monomers as is commonly understood in the industry and as described in the above-mentioned GB-A specifications. The term also includes mixtures of high density polyethylenes.
- the above core layer composition may optionally contain other additives such as e.g. an antioxidant and a lubricant.
- the thickness of the core layer is suitably greater than about lO ⁇ m, preferably greater than about 40 ⁇ m and is more preferably in the range from about 45-500 ⁇ m.
- the composite plastics sheet comprises, on its surface opposite the printable surface, a layer of plastics material compatible with the material of the core layer.
- This layer which is preferably a co-extruded layer, is selected to provide good heat-seal adhesion to blow-moulded HDPE bottles. In one embodiment this material may be of similar composition to the core layer but without the voiding agent.
- the material has a lower melting point than the core layer and can comprise heat-seal materials such as low density polyethylene (LDPE), ethylene vinyl acetate copolymer (EN A), ethylene methacrylic acid copolymer (EMA) and ethylene acrylic acid copolymer (EAA).
- LDPE low density polyethylene
- EN A ethylene vinyl acetate copolymer
- EMA ethylene methacrylic acid copolymer
- EAA ethylene acrylic acid copolymer
- Such materials are known to be co-extruded with the core layer of certain polyolefin films in order to improve the heat-activated adhesion characteristics, and any such processing layer materials are suitable.
- the invention encompasses within its scope the possibility that such a layer may be present on both sides of the core layer.
- any co-extruded layer on that side of the film would necessarily be underneath the printable surface coating on that side.
- the density of the base layer is considered to be the average density of the core layer and any co-extruded layers.
- any outer co-extruded layer is suitably below 50 ⁇ m, is preferably below lO ⁇ m and is more preferably from about 1 to 8 ⁇ m.
- the layer opposite the printable surface which has been selected to provide good heat seal adhesion, can be embossed to reduce the risk of blistering during in-mould labelling.
- This layer is preferably between 3 and 6 ⁇ m in thickness, more preferably between 4 and 5 ⁇ m.
- the composition of the outer co-extruded layer may also include other additives such as e.g. a lubricant (0-0.4% w/w); a wax, stearic acid or a metal stearate, especially calcium stearate; and an antistatic agent (0-6% w/w, preferably 2-4% w/w) of the ethoxylated amine type, all weights being based on the weight of the principal component of the composition.
- a lubricant 0-0.4% w/w
- a wax, stearic acid or a metal stearate especially calcium stearate
- an antistatic agent (0-6% w/w, preferably 2-4% w/w) of the ethoxylated amine type, all weights being based on the weight of the principal component of the composition.
- the presence of fillers and/or pigments in the outer co-extruded layer(s) provides a better grip during stretching of the co-extruded composite film.
- the core layer and one or more of the outer co-extruded layers may be co-extruded using co-extrusion equipment known in the plastics industry which may comprise one extruder for the composition employed to generate each layer and is adapted to feed a co- extrusion die fitted e.g. with appropriate flow distribution control or to feed a conventional die via an appropriate distributor block.
- co-extruded film or sheet comprises e.g. three layers with the core layer being sandwiched between two outer co-extruded layers this is preferably made in a single step using separate extruders for the core and outer layers but using a single die block.
- the film or sheet so formed may be oriented by stretching in an uniaxial or biaxial direction(s) according to known methods and this may be carried out sequentially or simultaneously. It is preferable to orientate the film/sheet by simultaneous biaxial stretching. Such orientation may be achieved e.g. by co-extruding the layers in the form of a tube and inflating it in a known manner.
- the layers are preferably co-extruded to form a continuous sheet or web which is then stretched employing a flat-bed stretching apparatus preferably of the type described in our prior published GB-A-1374574 and GB-A-1442113. Stretching of thermoplastic webs using such apparatus is described in our prior published GB-A-1490512.
- the surface of the base layer should be capable of receiving print and, in such a case, has a surface which may be suitably textured or modified by the presence of a pigment and/or a filler, and suitably has a printability corresponding to a wettability of at least 40 dynes/cm.
- the film or sheet produced from the formulations according to the present invention may be subjected to various treatments and surface coatings e.g. to enhance antistatic and printing qualities. It will be understood, however, that in the case where no separate printable coating is applied, and the base layer itself is destined to provide an external printable surface, it will usually be subjected to surface treatment such as oxidation via flame or corona discharge treatment to provide a more polar surface and the required wettability to more readily accept inks and coatings. Clearly, such treatments may be applied to the surface of any outer layer, whether or not such a layer is co-extruded to form the film or sheet.
- Surface printable coatings that may be applied to the film or sheet so produced include aqueous coatings commonly used in the paper industry and especially latex-based coatings. Of particular value in the present context, however, are the coatings described in our prior published GB-A-2177413.
- the coating solution comprises an aqueous system containing a polymeric binder, an absorbent pigment and an antistatic agent.
- a binder: pigment dry weight ratio is in the range 15:100 to 50:100, preferably 22:100 to 35:100
- the antistatic agent pigment dry weight ratio is from 0.4:100 to 2.5:100.
- the composition may also contain an insolubilizing agent.
- the polymeric binder may be in an aqueous or latex suspension, preferably a latex suspension, and should contain carboxyl groups on the polymer chain of at least one polymeric constituent.
- the binder may comprise a single polymer or a mixture of polymers.
- the binder may comprise, for example, starch or protein modified chemically or by physical addition of other polymeric species.
- the binder may comprise a carboxylated styrene-butadiene copolymer, an acrylic polymer or copolymer, or a vinyl acetate polymer or copolymer.
- the binder comprises a carboxylated styrene-butadiene copolymer.
- the binder content of the aqueous coating composition may be chosen to suit individual requirements, for example, the stiffness of the coated product.
- the binder content of the composition is in the range 15 to 30% by weight based on the binder plus aqueous phase, and more preferably in the range 20 to 25%.
- the absorbent filler may be any dispersible solid but is preferably an inorganic filler or pigment such as, for example, a calcium carbonate, china clay, titanium dioxide.
- the pigment comprises a china clay.
- the antistatic agent can be, for example, an ethoxylated amine or other material as conventionally used as an antistatic agent in the manufacture of polyolefin film.
- the insolubilizing agent is preferably a polyanionic zirconium compound, most preferably ammonium zirconium carbonate.
- EXAMPLE 1 A synthetic paper comprising a core layer and two outer co-extruded layers was produced as follows.
- the following compound consisting of a mixture of HDPE, particulate filler (CaCO 3 , TiO 2 ), voiding agent and processing aids, was used to produce the core layer of the extruded material:
- the two compounds were formed into a continuous three layer film by a conventional three layer co-extrusion process.
- the composite sheet extrudate was cooled by a series of conditioning rolls such that the sheet temperature was controlled to approximately 120°C for optimal biaxial orientation.
- the temperature stabilised sheet was then fed into a simultaneous biaxial stretching machine of the type described in GB-A-1442113 to give 4:1 stretching in both the machine direction (MD) and the transverse direction (TD). This gave rise to a plastic film of thickness 117 ⁇ m, and basis weight 70 g/m 2 , with a density of 0.6 g/cm 3 .
- the resulting product was subsequently used as a base layer in the production of a label for in-mould labeling.
- the film was coated on one side with a coating of the type described in our patent GB-A-2177413. This gave an 80 g/m 2 dried coated product.
- Label printing was carried out by offset litho and was followed by conventional die cutting.
- the blow-moulding process was performed on conventional equipment of the type well known in the art.
- the labels were placed inside the mould and held in place by vacuum suction prior to mould closure and blow-moulding. Heat from the molten HDPE parison then caused the label and moulded article to become fused in such a manner that a high quality defect free label and bottle was produced.
- Example 1 The procedure of Example 1 was repeated, except that the compound used for the basic or core layer was:
- the resulting plastic film was of thickness 105 microns, and basis weight 60 g/m 2 , with a density of 0.57 g/cm 3 .
- Example 1 The procedure of Example 1 was repeated, except that the compound used for the base or core layer was:
- the resulting plastic film was of thickness 105 microns, and basis weight 60 g/m , with a density of 0.57 g/cm 3 .
