First flexible, fast and affordable paper bagmaker With several of the major multiples now indicating a preference for paper rather than recyclable plastic for flexible film applications, packaging machinery specialist ILAPAK has collaborated with packaging manufacturer Van der Windt Verpakking to develop a breakthrough bagging solution. An adaptation of ILAPAK’s flagship Vegatronic 6000 bagmaker, the new system can run off paper pillow packs and pouches that can This means there can be a temperature films, ILAPAK’s solution offers three and any original films and complex be fully recycled via kerbside collection. variation of 15-20°C across the sealing clear advantages over its rivals: price, laminates without any changes other surface. Paper is a more heat-sensitive flexibility and speed. than adjusting the temperature via the “Our engineers have modified the forming material which requires heat to be applied tube and sealing system of the Vegatronic uniformly across the sealing area. ILAPAK 6000 to enable us to run an innovative has utilised specially treated sealing jaws paper film. With the likes of Tesco keen in conjunction with super-conductor for suppliers to pursue paper packaging, technology to ensure quick and even we are anticipating massive interest in transfer of heat. this new system. It is a fraction of the cost of other paper packaging machinery offerings plus it gives users the option “The only other systems that we are aware of for packing in paper films are considerably more expensive – up to four times the cost of our machine – and are dedicated to that application, so they don’t offer the same substrate Whilst there are other bagmakers on the flexibility. Our system is interchangeable market that claim to be able to run paper in that it can switch between paper control panel. Furthermore, whereas some baggers on the market can only manage 20ppm on paper applications, our system can maintain normal production speeds,” explains Tony McDonald. www.ilapak.co.uk of running original films on the same machine,” says Tony McDonald, sales and marketing director at ILAPAK UK. Pressure on the food industry to reduce non-recyclable packaging has intensified since the screening of Blue Planet II last year. One response has been to move from non-recyclable plastics to recyclable and paperboard industry is targeting no industries, including fresh produce, baked more than 3%. Most paper-based films goods, confectionery and pet food. available on the market today are in fact non-recyclable composite multi-layer This main challenge of running paper on a vertical bag maker is that it is very PE for some flexible applications. laminates with the appearance of paper. However, these plastics have to be taken Working together with ILAPAK, Dutch hard to produce a pack with straight lines packaging manufacturer Van der Windt and a perfectly formed gusset. The key Verpakking in cooperation with its printer to overcoming this issue is to hold the Cartomat, has successfully developed paper firmly in position and prevent it a paper film called CartoPaper® that from creasing prior to sealing. ILAPAK’s uses a special water-based water based engineers achieved this by modifying non-extruded coating to support both the forming tube to make the film path sealing performance and compliance through the forming shoulder and the with the European standard EN643.2. A remounting system smoother with less guaranteed paper content of at least 95% acute approach angles. to bag collection points for recycling and the UK’s infrastructure for processing these materials is over-capacity. Therefore, in recent supplier discussions, supermarkets such as Tesco have expressed a preference for paper films that can be recycled via household waste collections. The challenge with developing paper film that can run on bagging equipment is means this paper can be recycled. prone to creasing, which can make it The sealing system on the Vegatronic that it requires some plastic content to Using the industry-leading Vegatronic 6000 also had to be re-engineered. ensure a successful seal.
