Right: Ineos says its new line could prevent 1m t/y of plastic film going to landfill
the first time – besides the technology – was its reputation for reliability through the project execution process.” The 10.5 m wide film stretching line at the company’s new Lahore site includes a high-temper- ature machine direction orienter – for consistent quality – and a sliding chain track system in the transverse direction orienter for constant high- speed operation and reduced maintenance. Meanwhile, in China, Hengli Group has started up another 5.8m optical BOPET line at its new Fenhu site near Shanghai. This is the last of a 12-line package from Bruckner – all of which have been commissioned within one year. “The fact that all 12 BOPET lines have been successfully commissioned is an important mile- stone for our customer,” said Josef Haslinger, sales director for China at Bruckner. A further package of 12 BOPET lines – for the Hengli site in Nantong, Jiangsu Province – is already being processed and installation of the first line has started.
MDO line SML has set up a new version of its multi-purpose cast film line at its technology centre – which also includes a machine-direction orientation (MDO) unit. “The line has the technical capacity to fulfil almost every customer requirement in cast film production,” said Elias Mayrhofer, an R&D engineer at SML. The line can produce cast PP, PE and PET, as well as mono-oriented films. Products range from film for metallised and laminated food and non-food packaging to easy-to-recycle stand-up pouches made from MOPE film and easy-tear MOPP film. The line can be further optimised to make special- ist products, it says. A key feature of the new film line is the MDO
unit, which is designed for the manufacture of easy-to-recycle mono-material films such as MOPP, MOPE and MOPET. It allows machine direction properties such as film strength, stiffness and puncture resistance are increased, while film thickness and elongation are decreased. One of the main features of the MDO unit is the
process-optimised roller arrangement. Adjustment of the stretching gap takes place in a motorised fashion, making product changes simpler. As the stretching rollers have a diameter of 220mm, the stretching gap can be kept in a range of 50-200mm. The distance between stretching rollers can be reduced to a few millimetres. The position of the nip rollers in the stretching area is also adjustable. This ensures an ideal stretching process of the film, independent of the defined stretching gap.

All the process parameters of the MDO unit are digitally recorded and can be comfortably set and adjusted with SML’s new HMI.
Pilot prevention Ineos has commissioned a pilot line that it says will help prevent more than 1 million tonnes of plastic film going to landfill each year. The multi-layer blown film line with machine
direction orientation (MDO) has been installed at the company’s R&D centre in Brussels, Belgium. It allows customers to carry out full-scale tests without losing production capacity on their own lines. The first collaboration projects are already taking place. “Flexible packaging films play a valuable role in
society, but we recognise people’s concerns about plastic waste,” said Rob Ingram, CEO of Ineos Olefins & Polymers Europe. “Fully recyclable films are a big development and I’m excited about the possibilities created by our investment in this new MDO line.” The line, supplied by Hosokawa Alpine, heats
and stretches polymer films to improve their physical and barrier properties, so they can be used in different product applications.
Jindal expansion JPFL Films, part of Jindal Poly Films, has installed a new BOPP line at a plant in Nashik, Maharashtra, which it says will help it to expand production. The 60,000 tonnes/year line, likely to be in- stalled in 2026, will cost INR 2.5 billion (around US$30 million). It will produce rolls up to 1,700mm wide, with optimised efficiency for downstream processes such as metallising, it said.
