Definitions
- the invention relates to a new barrier coating, that is obtained by radiation curing, especially EB and UV curing, and to a process for manufacturing same.
- Films are widely used in numerous industries, for specific end-uses requiring specific properties. It is however very often that one film, although having good mechanical properties, lacks specific barrier properties.
- Laminates formed of a plurality of films, have thus been proposed.
- a 5-layer film such as PET/binder/EVOH/binder/PET, where PET is used for its mechanical strength while EVOH is used for its oxygen barrier properties.
- Other films have been proposed, with less or even more layers. Multilayer films are however costly to manufacture.
- gas barrier film is a metal foil, such as the aluminum foil.
- this foil suffers from the drawback of being not transparent, thus preventing customers from seeing the packaged goods.
- JP-A-08294989 to Sumitomo Bakelite discloses a process involving coating a radiation curable acrylate resin for protection purposes onto an alumine/silica gas-barrier layer.
- EB curing has been used so far in numerous fields.
- JP-A-7102089, JP-A-61243 and JP-A-6216047 disclose that EB curing will improve the gas barrier properties of an already polymerized layer, especially PVA.
- EP-A-69635 discloses polycarboxylic acid and polysacharride (hydroxyl groups) that create the gas-barrier film.
- EP-A-571074 discloses a polymeric article based on EVOH and carboxylic acid groups containing polyolefin.
- EP-A-567327, US-A-5567768, US-A-5545689 disclose melt processable polymeric blends containing vinyl alcohol and alkyl polymethacrylate copolymer.
- US-A-5221719 discloses a polyester gas barrier obtained by blending dicarboxylic acid and aliphatic glycol.
- WO-A-9215455 discloses a polyamide gas barrier obtained by blending dicarboxylic acid and diamine.
- US-A-5096738 and US-A-5215822 disclose a process where siloxane and carboxylic monomers in a solvent are solubilized and hydrolized, the solvent is evaporated off and the Si-O-Si bonds are grafted onto the organic polymer by EB curing.
- the invention thus provides a barrier coating, formed of radiation-cured repeating units, containing pendant polar group(s).
- the repeating units are monomers.
- the repeating units are acrylate-based repeating units.
- the polar groups are selected from the group consisting of hydroxy, carboxy and amino.
- the coating comprises straight polymer chains.
- the radiation-cured coating is EB-cured.
- the radiation-cured coating is UV-cured.
- the coating exhibits oxygen barrier and/or moisture barrier and/or aroma barrier and/or methyl bromide barrier.
- the coating is transparent.
- the invention also provides a substrate coated with a coating of the invention.
- the substrate is polymeric.
- the coating is sandwiched between two substrate layers.
- the invention finally provides a process for manufacturing the coating of the invention, comprising the steps of:
- the radiation-curing is EB-curing.
- the radiation-curing is UV-curing.
- the process is solvent-less.
- the substrate is polymeric and has been Corona treated prior to step (i).
- the instant coatings impart improved barrier properties to the substrates onto which they are applied and radiation-cured.
- the barrier properties are preferably gas-barrier properties, and may be oxygen barrier and/or moisture barrier and/or aroma barrier and/or methyl bromide barrier.
- the thickness of the coating can be comprised within broad limits, such as between 2 and 50 ⁇ m.
- oligomers examples are:
- oligomers and monomers are either commercially available or can be prepared by routine procedures.
- acrylate (or "acrylic), as used in the invention covers both the methacrylate (or “methacrylic”), form as well as the acrylate (“acrylic”) form, stricto sensu.
- Preferred repeating units are acrylate-based.
- the repeating units will contain pendant polar group(s).
- these pendant polar groups do not react during the polymerization reaction and will thus remain on the final barrier polymer.
- These groups will provide interchain hydrogen bonding and thus will impart further tightness to the polymeric coating.
- These polar groups can be selected from the group consisting of hydroxy, carboxy and amino. Preferably, where the repeating units are monofunctional (with respect to these polar groups).
- the cured coating will comprise a minimum of branching, so as to further enhance the tightness of the polymeric coating.
- straight polymers are the preferred coatings.
- the resulting coating is in most cases transparent, and can be either soft or rigid, depending on the substrate and the final intended use.
- Various additives can be added to the coating (at the stage where the repeating units are available as a composition). However, plasticizers should be avoided, while surfactant (or otherwise denominated wetting agent) are welcome. Silicone-based surfactants are preferred additives, especially silicone-acrylate based surfactant.
- the substrate can be any substrate that is compatible with the radiation-cured coating.
- Preferred substrates are polymeric and include PE, PP, PET, PVC, PA, etc. Corona treatment prior to coating composition applying is preferred.
- the substrate can also be paper, fabrics, non-woven, and the like.
- the thickness of the substrate can be comprised within broad limits, such as between 10 and 2000 ⁇ m.
- the thus coated substrates can be easily laminated on other substrates by using an appropriate adhesive, such as a polyurethane adhesive.
- an appropriate adhesive such as a polyurethane adhesive.
- the radiation-cured coating is sandwiched between two substrates (that can be identical or different).
- Different alternatives can be used in the manufacturing process, such as one step on-line production or more than one step (for each stage in the process, a different step would be present).
- the process of the invention is a solvent-less process.
- Corona treatment is a well-known treatment and is used to enhance bonding.
- plastics in general have chemically inert surfaces with low surface tension, which causes them to be less or non-receptive to bonding with coatings and adhesives.
- Polyethylene and polypropylene have the lowest surface tensions of the various plastics, and are the two materials most often subjected to corona treatment so as to improve their bonding characteristics.
- Corona treatment is however not limited to those two materials and can be used on any plastics.
- the corona treatment is carried out in a classical manner using a classical Corona apparatus.
- the Corona treatment may not be necessary when the film is for e.g. paper or fabrics.
- the first coating technique is reverse roll coating. Said technique is the most versatile and accurate coating technique for many applications. It can be used in a large range of coating solution viscosities.
- the main operating feature of reverse roll coaters is the application of the coating by a roll rotating in the opposite direction to the substrate movement.
- the coating formulation is premetered on reverse roll coaters, and the deposit thickness is substantially constant regardless of the substrate.
- the final coating thickness is controlled by the speed ratio between the applicator and backing rolls, the backing roll running substantially at the substrate speed.
- the second coating technique is gravure coating.
- This technique utilizes a driven engraved cylinder, an impression roll, a web transport roll, a doctor blade, a pan and/or applicator to apply a liquid formulation onto a web.
- This technique operates on the principle of pressing the web onto the engraved cylinder, removing liquid from the engraved cells or lines by capillary action and/or vacuum.
- This coating method is generally considered as well suited for long run jobs which are repeated often and require a very thin wet film thickness.
- the accuracy of a gravure coater is generally not speed sensitive (as long as each element is properly adjusted).
- the third coating technique is blade coating.
- the general principle in blade coating is that the applied coating is levelled with a thin steel blade of a 0,2-0,5 mm thickness, for example. By varying the pressure of the blade against the film, the final coat weight is adjusted.
- the radiation-curing techniques utilize an emitting source, which generates the proper actinic radiation.
- the following describes some specific techniques which may be used.
- UV-radiation encompasses radiation of the wavelength 200-400 nm.
- UV-curable coating formulations consist typically of a blend of reactive monomers or oligomers capable of free radical or cationic initiated polymerization.
- Photoinitiators (PI) are often used with UV-curable coating and they are the source of free radicals or cations produced upon irradiation.
- Many different chemical compounds can serve as PI. benzoin and its derivatives, aromatic carbonyls, halogenated chemicals and amines have found application in free radical mechanism, while aryliodonium salts and arylsulphonium salts have found application in cationic mechanism.
- Different PI may require different wavelengths and the radiation from the source and the PI sensitivity should be matched.
- the PI should absorb UV radiation in a range which is not absorbed by the monomer, oligomer or other additives.
- the most commonly used UV source a medium pressure mercury lamp, emits over a wide range of wavelengths and is thus
- the rate of curing reaction depends upon the number of free radicals or cations produced and thus upon the density of the UV reaction. Since most of the UV radiation is absorbed near the surface coating, a thicker layer usually requires extended irradiation time.
- UV irradiation equipment is typically comprised of the following parts: radiation source, lamp housing and reflector, accessories, power supply and controls, shielding and safety equipment.
- Electron beams belong directly to ionizing beams having energies greater than 3 eV. Electrons are generated in a vacuum, accelerated over a potential difference, and are then emitted via a thin film, generally made of titanium, into the atmosphere. Then they usually interact with some material which is deliberately put into their path. There are a number of effects which occur while the electrons are slowed down due do their interactions with this material. Besides generating primary electrons, back scattered electrons are also generated. The unit of energy delivered by an electron processor is usually recorded in megarads ; typical values of energy are comprised between 0,5 and 20 Mrad.
- the dose is used to express the energy required to cure a particular coating and is experimentally determined.
- a typical dose is comprised between 1,5 and 10 Mrad.
- the voltage applied is usually comprised between 150 et 250 kV.
- the dose received by a given coating and the voltage applied may vary within the depth of the coating, depending on the accelerating voltage, coating thickness and coating density.
- Typical EB-curing equipment is comprised of a vacuum chamber, an electron gun assembly, a window, a processing zone, self-shield, high voltage power supply and controls, shielding and safety equipment.
- EB or UV hybrid processing is a combination of either UV curing or thermal drying processes or EB treatment, a manufacturing method that fully cures, among others, coatings applied to paper or film substrates.
- Such a hybrid process is obtained by combining two or more curing techniques such as EB, UV or thermal curing into a manufacturing process.
- low energy, low heat UV is used to cure just the surface of each application of the coating formulation. Additional coats of wet formulation may then be applied and UV treated on the semi-dry surface before the full and final curing is completed by EB.
- Thermal coat formulation may be treated the same way as UV coat formulations to obtain a full cure, scratch resistance and improved adhesion to films.
- EB curing rapidly accelerates a chemical reaction in the coat formulation to produce a full curing.
