Grafobal has a new production line for corrugated cardboard
On September 12th, 2013 GRAFOBAL, a. s., Skalica officially launched the operation of a new corrugating and laminating line, the In line laminator Expertflute 150 from the Swiss company Bobst, which in addition to first-rate technical and production parameters, also meets the strictest environmental criteria.
This new modern equipment, with a length of 57 meters, streamlines, improves and expands the production of corrugated cardboard at Grafobal. It will also produce a very thin cardboard, type G, with a wave height profile of only 0.5 mm, which up till now hasn’t been produced in Slovakia nor even in the Czech Republic. The total investment cost of the new line is four million Euros. The new line can produce about 13,000 tons per year (i.e. 30 million square meters) of corrugated cardboard.
Corrugated cardboard is made from paper rolls with a width of up to 1.45 meters, while the maximum size of the sheets produced reaches 1.45 x 1.65 meters. By way of this investment Grafobal has established the unattended preparation of starch adhesive for bonding of the first two layers of three-layer corrugated cardboard, which fulfills in advance the upcoming, more stringent environmental requirements of the European Union, with the new type of adhesive used.
The machine enables the substantially thinner coating dispersion of the adhesive in the lamination section. On the new line installed at Grafobal, a closed circuit circulation of rinsing water from the adhesive sections that is recycled and re-used for the preparation of adhesives is also operational. Compared to its predecessor, the new line is equipped with an automatic system of insertion of empty pallets and the removal of pallets with laminating sheets.
The new line creates the conditions for strengthening the competitive advantage of Grafobal and for consolidating its position in the packaging segment for the electrical, food, glass and other consumer industries. Since 2009, when Grafobal produced 6.8 thousand tons (13,910,000 square meters) of corrugated cardboard, production has increased every year until last year’s nearly 11,000 tons (10.96 thousand tons), representing an increase of more than 60%.
