Definitions

  • the present invention relates to a coated paperboard, to products, especially containers and blanks therefor, made from coated paperboard and to a method of applying a coating to paperboard.
  • Paper and paperboard are widely used in the manufacture of containers, such as boxes, for storage and transport of produce.
  • the word "paperboard” will be used hereinafter to denote both paper and paperboard that is suitable for the manufacture of boxes and other containers.
  • the term "boxboard” will also be used to denote a material that is used in the manufacture of boxes, such as cardboard boxes. Although generally possessing satisfactory properties for the manufacture and use of such containers, paperboard will absorb moisture if the container is exposed to a wet or humid environment.
  • Moisture exposure may result from the weather, by splashing of the container, by storage in a high humidity environment, by emission of moisture from product stored in the container (e.g. fruit and vegetables) or by breakage of produce inside the container. Once the paperboard has absorbed moisture, its strength decreases quite dramatically.
  • the purpose of applying the wax is to give the paperboard sufficient strength under wet conditions that would otherwise lead to softening of untreated paperboard and consequent collapse under moderate compression load.
  • the wax acts as a water resistant layer to decrease water permeability into the paperboard.
  • the wax coating also has a strength associated with it and this also adds to the strength of the paperboard.
  • Wax levels currently used to coat paperboard destined for storage and transport containers typically result in the wax comprising from 50 to 60% of final container weight, with wax thickness of from 0.05 to 0.1 mm on exposed faces of the container and much thicker elsewhere.
  • the present invention provides paperboard having a coating applied thereto, which coating includes at least one triglyceride compound.
  • Triglycerides have a glycerol backbone and it is expected that this would result in the triglycerides taking up appreciable amounts of water. Compounds that take up appreciable quantities of water would be considered to be unsuitable for use as coatings for paperboard.
  • the present inventors have discovered that the triglyceride coating do, in fact, take up significant quantities of water. However, it has also been surprisingly found that paperboard coated with the triglyceride- containing coating of the present invention retains strength even after taking up water.
  • the paperboard of the present invention is suitable for fabricating containers that may be used in all applications in which present wax-coated containers are used.
  • the present invention provides a paperboard product characterised in that the paperboard product has a coating applied thereto, which coating includes at least one triglyceride compound.
  • the paperboard product is preferably a sheet of paperboard or a container blank.
  • the present invention provides a method for applying a coating to paperboard which comprises providing a molten coating composition including at least one triglyceride compound, applying said molten coating composition to the paperboard and allowing said molten coating composition to solidify to form said coating on the paperboard.
  • the molten coating composition may be applied to the paperboard by any convenient method known to those skilled in the art. Examples of suitable methods of application include passing the paperboard through a bath or pool of the molten coating composition or passing the paperboard under a shower of the molten coating composition.
  • Triglycerides are triesters of glycerol.
  • the hydroxyl groups of glycerol may be esterified with the same acid to form a simple triglyceride.
  • glycerol is esterified with two or three different acids.
  • the general formula for triglycerides is shown below: O I
  • R, R and R" may be the same or different and are usually - C 22 hydrocarbon chains.
  • the hydrocarbon chains may be saturated or unsaturated.
  • the coating including at least one triglyceride compound is applied to the paperboard such that the weight of the coating is up to 100% of the weight of the paperboard to which it is applied. It is preferred that the minimum amount of coating that is able to achieve that desired water permeability and crush strength parameters be applied to the paperboard. Using the minimum amount of coating will clearly minimise raw material costs.
  • the coating is more preferably applied in an amount of 30 to 70%, based upon the weight of paperboard. Any triglyceride that is solid under ambient conditions is suitable for use in the present invention. In general, saturated triglycerides fulfil this criterion.
  • a number of unsaturated glycerides are also solid at room temperature (although these generally have only a small degree of unsaturation) and such unsaturated triglycerides may also be used in the present invention.
  • a mixture containing liquid triglyceride(s) and solid triglyceride(s) may also be suitable for use.
  • the coating may include a single triglyceride or a mixture of two or more triglycerides. If a mixture of two or more different triglycerides are used the different triglycerides may have similar molecular weights or different molecular weights.
  • Example of triglycerides that may be used in the present invention include lard (a mixture of C 14 - C 18 saturated and unsaturated hydrocarbon chains), trimyristin (saturated tri-C 14 hydrocarbon chains), tristearin (saturated tri-C 18 hydrocarbon chains), hardened vegetable oil, hardened tallow, hardened fish oil, animal fats and dripping (beef tallow). It will be appreciated that this list is not exhaustive and many others triglycerides may be used in the present invention.
  • One or more plasticisers may also be added to the coating in order to improve the flexibility of the coating composition.
  • the addition of plasticizers can impart improved flexibility, increased water resistance, reduced brittleness, and affect tackiness and blocking properties. Addition of one or more plasticisers to the coating will act to reduce brittleness of the coating and hence reduce the risk of the coating flaking off the paperboard during use.
  • the plasticiser is preferably added in an amount such that the plasticiser comprises 1-10% by weight of the total weight of the coating, with 3-5% by weight plasticisers being more preferred.
  • plasticisers examples include low molecular weight polyester plasticisers, low density polyethylene, polyethylene wax methyl oleate, ethylene vinyl acetate (EVA) copolymers, cetosteoryl stearate, butyl stearate and beeswax. Low density polyethylene and EVA copolymers are preferred.
  • EVA ethylene vinyl acetate
  • This list of plasticisers is not exhaustive and a number of other plasticisers that are compatible with triglycerides may also be used. A mixture of different plasticisers may also be used.
  • the ⁇ lasticiser(s) used in the present invention are non-toxic and readily biodegradable.
  • the coating composition must first be placed in the molten state.
  • the coating composition is preferably heated to a temperature of 5-30°C above its melting point by any known heating method. For most coating compositions used in the present invention, this temperature is below 100°C and often in the range of 40 to 90°C.
  • the actual temperature to which the coating composition is heated should be sufficiently high to ensure that the composition is molten whilst avoiding changes to the triglycerides due to elevated temperatures.
  • the mixed composition goes through a gel phase as the temperature is increased, and it passes through the gel phase to a completely molten, liquid phase at higher temperatures.
  • the coating composition be heated to a temperature above that at which the gel phase exists.
  • the coating composition is heated to a temperature above its cloud point.
  • the cloud point is the temperature at which visible opacity first appears during cooling of the molten coating.
  • the molten coating composition is then applied to the paperboard. A proportion of the applied coating is absorbed into the paperboard and the remainder coats the surface of the paperboard to form the coating.
  • the coating preferably coats both facing sheets of the paperboard and also coats the fluted layer sandwiched between the facing sheets.
  • the coating is then cooled to solidify the coating composition. Cooling may take place under controlled conditions. Alternatively, the coating may be allowed to cool by placing the paperboard in ambient conditions.
  • the molten coating composition can be applied to the paperboard by any method known to a skilled person. Preferred methods includes dipping or otherwise passing the paperboard through a bath or pool of molten coating composition, or by passing the paperboard under a shower of molten coating composition. Preferably, the coating process is controlled to saturate all surfaces of the board (including within the fluted core of corrugated board).
  • the coated paperboard product produced by the present invention is especially suitable for use as storage and transport containers or boxes.
  • the paperboard is pre-cut to a container blank prior to coating the paperboard.
  • the triglyceride compounds used in the present invention may be edible, are readily biodegradable and can be obtained from renewable resources, such as animal fat, fish oil and vegetable oil.
  • use of triglyceride-containing coatings allows for potentially better recyclability than current petroleum-wax coated products. Triglycerides will melt in hot water and agitation of used paperboard in hot water will remove at least some of the triglycerides from the paperboard. The triglycerides, in being less dense than water, will float and can be recovered from the surface of the water.
  • the first method is a non-destructive method and offers the possibility of separating the triglycerides from the surfactant/detergent and to recycle the triglyceride.
  • Methods (ii) and (iii) above are destructive to the triglyceride.
  • Example 1 The invention will now be described in more detail with reference to the following Examples.
  • Example 1 The invention will now be described in more detail with reference to the following Examples.
  • the water uptake of three triglyceride films in both cool room conditions and cold water immersion was investigated.
  • the triglycerides were lard, trimyristin and tristearin. Sessile drop water contact angles for each triglyceride coating were determined to be as follows: lard : 111 ⁇ 5° trimyristin: 118 ⁇ 5° tristearin : 112 ⁇ 5°
  • Samples of coated paperboard were prepared by placing 230 Liner (paperboard) in an oven at 60°C until ready for use.
  • 230 Liner is a commercial grade paperboard/boxboard used in the manufacture of containers and blanks therefor. This removed any water from the liner.
  • the triglycerides were heated to approximately 20°C above their melting points and the liner was dipped in the liquid medium for about 5 seconds, after which it was removed and allowed to drain on an absorbent piece of paper. All coated materials were allowed to cool at room temperature for at least one hour before undergoing any tests.
  • the mass of the triglyceride coatings was 0.8 to 1 times that of the original weight of the native paper.
  • the native or coated samples of paper were totally immersed in a beaker of water at 4°C. At various time intervals they were removed and placed to drain on an absorbent tissue for one minute before weighing after which they were re-immersed until next removed for re-weighing.
  • the native or coated samples of paper were left hanging in the humidified and temperature controlled storage unit.
  • the cool room environment was maintained at 92% relative humidity and 2°C.
  • the paper samples were removed and placed to drain on an absorbent tissue for one minute before weighing, after which they were returned to the unit until the next weighing.
  • Figures 1 and 2 The results of the water uptake experiments are shown in Figures 1 and 2.
  • Figure 1 shows the coolroom tests
  • Figure 2 shows the cold water immersion tests.
  • All the triglyceride coatings significantly reduce the water permeation into the paperboard.
  • similar tests were conducted for paper coated with a commercially used wax coating.
  • Example 2 Five samples of triglycerides were obtained and investigated. The samples were: hardened vegetable oil (fully refined); hardened tallow (semi-refined); - hardened tallow (fully refined); - hardened fish oil (semi-refined); and hardened fish oil (fully refined).
  • Example 1 and 2 The coating used in Example 1 and 2 were applied to paperboard that had been dried prior to coating. In commercial application, coating would be applied to paperboard that will be in equilibrium with the ambient humidity and hence will contain absorbed water. To determine if this would adversely affect the coating a series of experiments were carried out in which triglyceride coatings were applied to paperboard that had been allowed to equilibrate at ambient temperature (21°C) and humidity (50%). The coatings applied included these used in Examples 1 and 2, together with Dripping (beef tallow) and Supafry (a blended animal and vegetable oil). For comparison purposes, similar tests were carried out using pre-dried paperboard.
  • Example 1 to 3 included coatings that comprised a single triglyceride. It was observed that some of these coatings were somewhat hard and brittle. Although the hardness of the coating contributed to the dry strength and the wet strength of the coated paperboard, the coatings were observed to flake off in some instances. In order to try to decrease the brittleness of the coating, an experiment was run in which small amounts of low molecular weight polyethylene (plasticiser) were added to hardened tallow (semi-refined). The results are shown in Figure 5 and reveal that small amounts (up to 5%) of low molecular weight polyethylene improved the water resistance properties of the coated paperboard.
  • plasticiser low molecular weight polyethylene
  • Example 5 A series of coatings were prepared on a boxboard substrate such that the uptake of coating on the boxboard was about 58% w/w (i.e. the coating weight was about 58% of the weight of the uncoated boxboard).
  • the coatings used included hardened tallow, a hardened tallow/polyethylene plasticiser mix, and a commercially available wax coating.
  • Figure 6 shows edge-wise crush strength versus water uptake after 48 hours in cool room conditions. On average, the results show that the hardened tallow and the hardened tallow/polyethylene plasticiser mixture appears to take up 2 to 3 times more water than boxboard coated with the commercially available wax coating.
  • Example 6 Boxboard was coated with a series of coating compositions under conditions such that a coating thickness corresponding to 30% w/w was obtained.
  • the coating method included dipping the boxboard into molten triglyceride, allowing the coating to cool and subsequently dipping into a hexane solution to remove some of the coating. The coated sample was then oven dried to remove volatile hexane.
  • Figure 7 shows edgewise crush strength versus water uptake for various coatings at 30% w/w after 48 hours in cool room conditions.
  • the boxes were coated with a hardened tallow coating or a hardened tallow
  • the triglyceride coated boxes displayed significantly greater crush strength than the commercially available wax-coated boxes; approximately 7.5 kN, irrespective of coating uptake, for the triglyceride boxes compared with approximately 5.5 kN for the commercially available wax-coated boxes.
  • the hardened tallow used as the basis for most of the previous Examples consists mainly of C 18 and C 16 hydrocarbon chains.
  • hardened coconut oil mainly (C 12 and C 14 ) and partially hardened fish oil (mainly C ⁇ and C 22 ) were used for further trials.
  • Figure 8 shows the water uptake in cool room conditions of paperboard coated with pure hardened coconut oil and various mixtures of tallow and hardened coconut oil. The addition of the hardened coconut oil slightly increased the water resistance of the hardened tallow-based coating. The coating of pure coconut oil increases the water resistance substantially.
  • Figure 9 shows the water uptake of paperboard coated with hardened tallow doped with partially hardened fish oil when placed in cool room conditions.
  • the addition of partially hardened fish oil increases the water resistance of hardened tallow more than the fully hardened coconut oil.
  • the coating of pure partially hardened fish oil increases the water resistance substantially.
  • Hardened tallow was mixed with various additives in order to investigate the properties of the resulting mixture.
  • the additives included tributyrin, dodecanol, beeswax, butyl stearate, cetostearyl stearate, lanolin and methyl stearate. All of these additives improved the relative flexibility/flaking of the hardened tallow, with some of the fatty acid ester materials (butyl stearate, cetostearyl stearate and lanolin) having the best effect.
  • Figures 6 and 7 also contain edgewise crush strength versus water uptake for boxboard for hardened tallow-based coatings containing 3% of either butyl stearate or cetostearyl stearate, after 48 hours in cool room conditions.
  • the coatings have similar properties to the hardened tallow/polyethylene plasticiser coatings.
  • the previous Examples detailed investigations of paperboard coated by dipping the paperboard into molten coating material. It is believed that this coating method does not result in ideal coatings. Therefore, a pilot scale cascade coater was constructed to enable coating to take place under controlled conditions whilst using a process similar to that used on the commercial scale.
  • the cascade coater comprises a heated lower reservoir for holding a pool of molten coating material.
  • a pump is used to raise the molten coating material to an upper reservoir having a weir. Overflow from the upper reservoir cascades over the weir and a box blank can be moved back and forwards through the falling cascade to coat the blank.
  • the pilot scale cascade coater allows for accurate control of the temperature of the molten coating material, flow of the molten coating material and air flow. Variable coating thicknesses can be obtained using the cascade coater.
  • a series of trials were conducted using the pilot scale cascade coater in which cardboard box blanks were coated. After the coating had hardened, the box blanks were folded into boxes and box crush tests were conducted on the boxes, after the boxes had been exposed to ambient conditions (23°C, 50% relative humidity) or cool room conditions (2°C, 95% relative humidity, 72 hours).
  • the trials were conducted using a commercially available wax coating and a triglyceride coating comprising 97% hardened tallow and 3% polyethylene plasticiser. Both coatings were applied at variable coating pick-up.
  • the boxes used had dimensions of 570 x 370 x 300 mm (approximately) and were made from corrugated boxboard. The results of these trials are given in Tables 3 to 11.
  • Table 12 shows a 50% w/w coating comprising 95% hardened Tallow and 5% polyester plasticiser. Comparison of the results for the commercially available wax coating and the triglyceride-based coating show that the boxes coated with the triglyceride-based coating have superior dry strength to the wax coated boxes, but exhibit slightly lower wet strength than the wax coated boxes. Strength increased with increasing coating uptake. Table 13 shows dry strength and wet strength properties of uncoated paperboards. The results of Table 13 clearly show that the coating of the present invention improves the dry strength of the boxes and markedly increases the wet strength of the boxes.
  • the triglyceride-based coatings of the present invention produce coated paperboard articles that exhibit satisfactory wet strength properties.
  • the coatings are transparent, made from a non-solvent base and are sourced from renewable resources.
  • a very important feature of the triglyceride-based coating of the present invention is that they allow for recycling of the paperboard.
  • Initial trials using boxboard coated with a coating comprising 97% hardened tallow and 3% polyethylene plasticiser were conducted using a laboratory scale repulper in order to assess the recyclability of the paperboard. It was found that the triglyceride coated boxes defibred quite readily. Hand drawn sheets were made from the repulped material and the quality of the material so-produced was similar to that of recycled uncoated boxboard. It was noted that more beating/repulping time was required to recycle the triglyceride-coated boxes.
  • the triglyceride materials used in the coatings are readily hydrolysed to form fatty acids which are readily biodegradable under both aerobic and anaerobic conditions.
  • the coating material is unlikely to persist in the environment if coated boxes are disposed of as waste rather than being recycled.
