Definitions
- the present invention refers to a White Top Kraftliner paper that comprises two to three layers of chemical fibers, which can be bleached and/or unbleached in which the layers total 100% of eucalyptus short chemical fiber, and at least one mass additive. It also refers to the process of producing said paper, use thereof and a package produced with said paper.
- White Top Kraftliner paper is widely used in the international market and is defined as a paper predominantly formed from primary kraft pulp.
- White Top Kraftliner papers can be produced from mixtures of chemical fibers (long fibers and short fibers).
- the composition of the pulps depends on the quality requirements of the paper and the weight of the resulting paper can vary between 100 to 300 g/m 2 , in most cases.
- White Top Kraftliner has a covering layer composed of bleached primary kraft pulp, which gives this layer differentiated optical properties, being indicated for boxes with high demand for print quality, where brightness, roughness and gluing are also evaluated.
- White Top Kraftliner papers play an important role in packaging, such as corrugated cardboard boxes, as they participate in its composition as an outer cover, and help to define its properties. As these boxes protect their contents from impact during handling, transport, storage, stacking loading, extreme temperatures and humidity, White Top Kraftliner paper has to meet general strength requirements such as: tensile strength, burst strength, compressive strength, ply bond, as well as providing adequate porosity and Cobb value.
- SCT Short-span Compression Test
- Typical applications for White Top Kraftliner include packaging for: food, beverages, cosmetics, electronics, hygiene and cleaning, vegetables and flowers, electrical materials, chemicals and derivatives, clothing and footwear, glass and ceramics. Packaging with greater added value, with prints with four colors or more, the white substrate highlights and works with one more color, being another differential of the White Top Kraftliner over the Brown Kraftliner.
- the document BR 11 2016 006857-2 discloses a multilayer board comprising pulp of cellulosic fibers, in which 100% of the total fiber content of said board is hardwood fibers.
- the document further discloses that the cardboard in question may also comprise dry strength additives, such as starch.
- starch is not superficial and the paper described has at least three layers.
- Patent application WO 1992013137 A1 describes a Kraftliner paper formed by several layers, preferably between 2 and 3, with fibrous composition of the cover layer formed from 50 to 100% of bleached hardwood sulphate pulp, added from 0 to 15% of pigment, calculated on a dry pulp basis. The remainder of the fibrous composition of the cover layer is composed of bleached or unbleached coniferous sulfate pulp.
- surface starch was not mentioned.
- Patent application PI 0918112-1 discloses the use of a new strength agent in the papermaking process, such agent being hydrophobic starch. In addition to being more focused on the starch itself and not the paper, the application of starch in such a document is not superficial.
- the formation of the sheet is not good and it has dark and light spots or a flocculated appearance that can influence physical-mechanical properties;
- the surface of the sheet is rougher and directly impacts the print quality
- Chemical fibers can be bleached or unbleached or mixtures and compositions thereof.
- a third objective is the use of White Top Kraftliner paper for the manufacture of a package, such as a box comprising said paper and a package for various applications.
- the present invention has as one of the objectives to provide a paper of exceptional quality that comprises two to three layers of chemical fibers in which the layers total 100% of short chemical fiber on a dry mass basis; and at least one bulk additive. [016] With this paper, the present invention presents a new solution to technical problems faced, since the White Top Kraftliner paper of the present invention provides:
- the present invention relates to the process of producing said paper and a package produced with said paper.
- Figure 1 Illustrates one of the possible configurations of the present invention for a White Top Liner paper with two layers with application of superficial starch.
- Figure 2 Illustrates one of the possible configurations of the present invention for a White Top Liner paper with three layers and application of superficial starch.
- Figure 3 Illustrates one of the possible configurations of the present invention for a White Top Liner paper with two layers (without application of surface starch).
- Figure 4 Illustrates one of the possible configurations of the present invention for a White Top Liner paper with three layers (without application of surface starch).
- the present invention relates to a White Top Kraftliner paper comprising (i) two to three layers of chemical fibers in which the layers total 100% eucalyptus short chemical fiber on a dry mass basis; and (ii) at least one bulk additive.
- the short chemical fibers present in the composition of White Top Kraftliner paper are short eucalyptus fibers, which can be bleached and/or unbleached or their mixtures, depending on the layer.
- a White Top Kraftliner paper with a higher content of eucalyptus short fiber provides a product with better quality, lower grammage and lower cost.
- the White Top Kraftliner paper has one or two base layers comprising unbleached short chemical fiber and a surface or cover layer formed by bleached short chemical fiber.
- At least one of the layers of the present invention may contain bulk additives, such as: starch, polymers and nanocelluloses or their mixtures.
- Nanocelluloses are selected from: microfibrillated cellulose, nanofibrillated cellulose, nanocrystalline cellulose, cellulose filaments or mixtures thereof.
- the putty additives can be applied on the surface or cover layer of the paper and even between the layers that make up the paper.
- Nanocelluloses can also be applied as single components or in formulations with other renewable or non-renewable polymers.
- the mass additive is applied to the surface or cover of the paper.
- the dough additive is starch.
- a layer of mass additive, preferably starch, can be applied on the surface or covering of the paper, with the objective of compensating losses of physical-mechanical resistance when the fraction of softwood in the composition is reduced.
- the White Top Kraftliner paper of the present invention is composed of two to three layers of chemical fibers wherein the layers comprise 100% eucalyptus short chemical fiber, with a layer of starch applied to the surface. of paper.
- concentration of the mass additive can be from 0.1 to 30 kg additive/t of paper.
- the White Top Kraftliner papers of the present invention were produced following the following steps: a) preparation of unbleached chemical pulps of eucalyptus short fibers; b) preparation of the chemical pulp of bleached short fibers (ECF) of eucalyptus; c) feeding the fibers from steps a) and b), in suspension form, on a sheet forming table, where partial dewatering occurs; and d) subsequent pressing and drying to remove residual water.
- the White Top Kraftliner paper of the present invention was produced in grammage of 150 g/m 2 .
- the packaging of the present invention comprises the White Top Kraftliner paper of the present invention in the form of boxes.
- Comparative tests were carried out and the results obtained were surprising, in which the White Top Kraftliner paper produced with three layers comprising only short chemical eucalyptus fibers presented physical-mechanical properties superior to papers with three layers produced with long chemical fibers in its composition, used as a reference. This is totally unexpected and provided by the coating of White Top Kraftliner paper with starch on the surface of the paper.
- the White Kraftliner paper of the present invention comprises 3 layers (base, middle and cover) in which the layers comprise 100% eucalyptus short chemical fibers, with b) a reference paper, produced in a three-layer paper, consisting of:
- Table 4 Physical-mechanical properties of White Top Kraftliner paper with 100% eucalyptus short chemical fiber at grammage of 150 g/m 2 , with and without application of surface starch, and KlaLiner White reference paper
