Current demands on the boxmaker by the retail

Wellpack's 'Clean Slit System' has two small knives that penetrate the outer liner, creating a minute score that sits both sides of a tear tape placed on the inner liner. When the tape is pulled, the tear does not travel into the fibres of the outer liner that would normally destroy any print and leave the box in a distressed state. Applications of this type of opening are increasing all over Europe, while American and Australian markets are now exploring this option. When customers consider this option, the most common question asked is how will this affect box performance (BCT). The answer, after many years of market experience, is clear when samples of a customer's box specification with Clean Cut and a plain box are examined. 'When the customer makes up the boxes at his own plant and carries out his own tests, we have never seen a result that has shown a BCT reduction of less than 6 per cent from liner slitting v's a plain box,' says Mr Andersson. 'The traditional option has always been to use a perforation to create this type of opening. Reduced BCT with a perforation is considerably more than that of the Clean Slit System. Generally speaking, when using a perforation option, the board weight has to be increased to meet the demands the box will be put under during transit. However, the Clean Slit option doesn't demand increased paper weight to allow for a clean and attractive opening solution.' The Wellpack taper uses tapes from 4mm to 25mm without the need to change any component on the machine. Its E&L web guidance system allows for accurate positioning of tape on the board. Installation is normally carried out during a weekend with no disruption to start-up. The domestic corrugated package industry has been going through very difficult times because of the hefty price rise in all major raw materials, mainly kraft paper, starch powder, and stitching wire, which comes to over 70% of the total input cost. Paper mills have increased the prices of kraft paper by Rs 4,000-4,500 per tonne in the last three months.Besides, prices of starch powder has gone up by about Rs 2,500-3,000 a tonne. Stitching wire prices have gone up by about Rs 50 to Rs 75 a kg, sources said. 'Corrugated packaging manufacturers will now have no option but to increase their product prices by nearly 25-30% in the days to come,' Pankaj Shah, senior ex-president, Western India Corrugated Box Manufacturers Association (WICBMA) said. The end users do not fully appreciate the situation the industry is in and are not willing to compensate fully the increase in the cost of inputs, he said.
