performance of BOPP film with the optical and tactile characteristics of paper. Packaging made from this material is leakproof, with a high barrier. “HybraPack makes it possible to exploit the advan-


tages of BOPP and PAL film for liquid and paste package contents,” said Jürgen Schischko, technical service manager at Treofan. “We are aiming to open up new product segments in the upright pouch market, which is currently seeing double digit growth.” Swiss company Trinity Haircare will use Hybrapack


Right: One of the first


applications of Treofan’s BOPP/paper packaging is a professional shampoo brand


to make stand-up pouches for its professional hair care products. Prior to this, Treofan developed a five-layer metal- lised BOPP film that uses Vistamaxx polymers from ExxonMobil in the heat sealable side of the film in order to improve the sealing properties. It helped to simplify the laminate structure,


remove the need for aluminium foil and reduce costs in comparison with alternatives. Treofan was looking to develop a


new BOPP film for packaging instant soups, but would also be suited to other kinds of dehydrated powdered product such as spice blends or instant sauces. The film, called Treofan MSB 30,


replaces the aluminium foil and PE sealant normally found in this type of packaging. On the outside of a soup pouch, many brand owners prefer printed paper. Here, a reverse printed BOPP film or a printed PET film can be applied. “Vistamaxx performance


polymers are key to the development of Treofan MSB 30,” said Paul-René Clauss, sales developer for Vistamaxx performance polymers at ExxonMobil Chemical. “They enable the laminate structure to be simplified, while boosting sealing performance.” Separately, Treofan says it has begun offering its


customers phthalate-free packaging film on request. While the company’s products already have a very low phthalate content of 0.001% – far lower that the typical 30% found in PVC film – some customers were beginning to demand products that were completely phthalate-free. The company says it can now do this, without compromising product quality.


Belgian BOPP boost Jindal Films Europe is to increase biaxially oriented polypropylene (BOPP) film production at its Virton site in Belgium. The company will install a 10.5m orienta-

tion line, which has a capacity of 50,000 tonnes/year. It will replace existing production lines and is expected to be completed by the end of the third quarter in 2018. The expansion is part of an investment strategy that began in 2015 at its Brindisi facility. “Virton is the most flexible plant to produce our wide


range of speciality and new generation products,” said Serge François, Virton site director. “The new orienta- tion line will allow us to better serve our customers with end products that meet their evolving expectations in terms of product innovation, quality and dimensions.” The company recently introduced new transparent BOPP high barrier and sealant films, which remove the need for a PET layer. Alox-lyte 16AO893 and 16AO893 boost shelf life by adding a transparent barrier, while allowing vibrant printing.


Both grades can be used to


create mono-material or polyolefin- based laminates. The amount of aluminium used in the barrier is one-tenth of that used in a typical metallised BOPP films of similar performance, says the company. The use of aluminium oxide –


rather than aluminium foil – means that metal detection can now be used at the end of the filling line to check for metal particles – a better option than X-ray detection, says the company. Both films are BOPP-based and


16 microns thick, with a WVTR of 0.7 g/m²/24h and typical OTR of 0.5 cm³/m²/24h. The 16AO893 grade is


a middle-web solution, giving ease of processability within a three-ply laminate, while 16AO894 is designed for improved sealing performance.


Pinhole detection Bobst says that its Hawkeye system helps producers of metallised film to cut the number of surface defects – such as pinholes – which can affect barrier properties such as water vapour and oxygen transmission rates. Also, the system can help to ensure that films are made with the correct optical density (OD) coating deposition of aluminium film. Hawkeye can handle both tasks simultaneously – in- line – at high production speeds without compromising the quality of metallisation, says Bobst. Its inline OD measuring system is based on the


Bobst Registron module, and eliminates the need for offline checking – further reducing the risk of customer
