THIS INVENTION relates to the manufacture of articles from liquid packaging board, in particular unused or used waste liquid packaging board. In ) particular it relates to a feedstock for manufacturing articles and to a method of ] manufacturing articles using liquid packaging board. The invention extends to an article produced from the feedstock or In accordance with the method of the invention and to an article having a particular composition.
In accordance with the invention there is provided a feedstock for manufacturing an article, which includes pieces of liquid packaging board; a thermoplastic polymer; and a bonding agent.
Further in accordance with the invention there is provided a method of manufacturing an article, which includes admixing pieces of liquid packaging board, a thermoplastic polymer, and a bonding agent; heating the mixture; and forming the heated mixture into the article.
The article may be formed by an extrusion, Intrusion, pressing or injection moulding process.
Still further in accordance with the invention there is provided an article which comprises pieces of liquid packaging board, a thermoplastic polymer; and a bonding agent.
The invention extends to an article made from the feedstock, or in oo accordance with the method, described above.
It will be appreciated that liquid packaging board has various layers, including layers of polyethylene and wax coated fibrous board, the board usually being of paper or cellulose and aluminium foil The polymer may thus be } polyethylene or polypropylene. The bonding agent may then include acrylic acid, maleic anhydride, and tree rosin pentaerythritol ester.
As indicated above, unused or used waste liquid packaging board may be used.
Some of the liquid packaging board may be replaced by an organic fibrous component in particle form. Thus, the ratio of organic fibrous component to liquid packaging board may be as much as 75%:25%. The particles of the fibrous component may be cellulose-containing particles selected from materials which are members of the group consisting of flax, rice husks, cane, jute, sisal, hemp, coconut, kenaf, wood (for example from wood pulp), paper and suitable mixtures thereof.
Typically the fibrous component comprises wood fibre, for example sawdust particles. The organic fibrous component may also be waste material.
The pieces of liquid packaging board may comprise between 50% and 70%, preferably 55% to 65%, and most preferably about 60%; the polymer may comprise about 30% to 40%, preferably about 35%; and the bonding agent 1% to 7.5%, preferably about 2%, by weight.
The pieces of liquid packaging board may be provided by sub-dividing sheet portions of liquid packaging board, for example by chopping in a granulator.
The pieces may have a size of less than about 4mm, preferably less than 3.5mm and most preferably less than 3mm.
The feedstock may be provided in pellet form. oo If an extrusion process is used, the polymer and bonding agent may be mixed together and this mixture and the pieces of liquid packaging board may be fed separately into the extruder. ) The article may, in particular, be a strip for a pallet.
The article may be formed at a temperature of between 110°C and 375°C, depending on the polymer used.
In a particular example pieces of unused waste liquid packaging board from Tetrapak were chopped to a particle size of less than about 3mm and fed into an extruder. Granules of high density polyethylene were mixed with a bonding agent comprising acrylic acid in solid form, maleic anhydride and a lubricant and this mixture fed separately into the extruder. The pieces of liquid packaging board comprised about 60%, the polyethylene about 35%, the acrylic acid about 0.5% and the maleic anhydride about 1.75% by weight. The extruder was operated at an exit temperature of about 170°C and a strip was extruded having dimensions of 25mm by 130mm.
