With the growing demand for more sustainable and eco-friendly alternatives to plastic in the packaging industry, many developments have been made in the field of bio-based materials in the recent past.

    Following are a few innovations that demonstrate potential.


  • Sustainability in Packaging Asia

    Sustainability in Packaging Asia

    Sustainability In Packaging Asia is Going Virtual in 2020! Since its launch in US in 2006, our sustainability in packaging conference has gone from strength to strength and has been successfully launched in Europe. * As the packaging industry faces growing consumer and regulatory pressure to find sustainable packaging options that ‘reduce, reuse and recycle’, companies across the value chain are looking to sustainability to differentiate from their competitors and win new business. Brands have ambitious sustainability goals to hit, converters want to champion the sustainable credentials for their materials and raw materials companies are innovating to solve performance and end of life issues. * The challenge is that the things that make packaging (especially plastics packaging) effective at its job (its cheap and durable) also hinder its sustainability – it lasts a long time and is uneconomical to recycle * Asia is becoming a key arena for sustainability discussions because the consumer base is growing quickly and with it demand for packaging but the recycling infrastructure and waste management is less developed. China’s recent‘National Sword’policy has curtailed European and US plastic waste going to China to be recycled and created heightened awareness of sustainability in both China and surrounding countries. As global brands look to Asia to drive their growth, Asia provides many opportunities and challenges for creating a growing need for sustainable packaging solutions in the region and these will create the key themes for this new event.


    ALPLA acquired its first production facility in Greece in 2018 with its acquisition of ARGO S.A. Located in Koropi just outside of Athens, this plant has decades of experience in the manufacture of packaging for the industries of cosmetics, pharmaceuticals, crop protection and chemicals. One of ALPLA Greece's specialist areas is the production and decoration of high-quality tubes. There are numerous options here in terms of the materials and the packaging printing processes. Production of tubes and closures A production line continuously moulds sleeves out of polyethylene (PE) in diameters of 19, 25, 30, 35, 40 or 50 millimetres. Apart from various colours, customers choose between low-density PE (LDPE), medium-density PE (MDPE) and high-density PE (HDPE), thereby also determining the level of force required to squeeze the tube when in use. The sleeves are cut to a specified length and a tube neck is then attached to them on a second production step. This involves an open end of the sleeve being forced into a mould. The high pressure forms the tube neck while also attaching it to the sleeve (compression moulding). Different closure types, e.g. screw caps or flip-top, are also manufactured at the plant. Tube printing The next production step is printing the tubes using various printing processes. This requires a great deal of experience in dealing with the technology, materials and colours. Especially for cosmetics manufacturers, high-quality imprinting is one of the most important attributes for presenting their products to the consumers. They therefore set great store by individual designs and perfect execution. Offset printing or flexographic printing is used, depending on the requirements. Dry offset printing is the standard solution for less detailed templates. Four-colour CMYK flexographic printing is the preferred choice for more detailed and colourful pictures such as faces or flowers. Texts are printed be means of silk screen whereas foil stamps such as logos or brand names in gold or silver can also be applied to the packaging by means of a cold foil technique. What makes the production special is that it can handle a combination of different techniques such as flexographic printing, screen printing and foil coating on a single, state-of-the-art hybrid printing press. Thanks to this cutting-edge printing technology, the customer then has a perfectly coordinated end product and ALPLA Greece received a silver award in the “Hybrid Packaging Printer of the Year” category of the Printing Awards 2020. In the final step, the closures are screwed onto the printed tubes, and these are then packed and delivered to the customer to be filled via the bottom opening. This opening is then sealed after filling to give the tube its characteristic appearance. Recycled material becoming increasingly important The topic of recycling is becoming increasingly important in the area of tube production too. The plant in Koropi is already receiving an considerable number of requests for tubes made of post-consumer recycled material (PCR material) and has garnered some experience in producing these. These materials are on a par with newly produced PE in terms of their barrier properties and food suitability. Only in terms of colour and appearance there are minor differences, as PCR material is slightly darker than HDPE or LDPE. Within the ALPLA Group, research is also being conducted into new bio-based materials that could be used for tube production in the future.
  • Coca-Cola European Partners invests in PET recycling start-up

    Coca-Cola European Partners invests in PET recycling start-up


    According to Cure, its partial depolymerisation process allows the removal of many impurities and the conversion of food grade PET to high-quality rPET, that can be used again for food and drink packaging. Following its commercialisation, CCEP will receive the majority of the output from a Cure -licensed, new-build plant. It will reportedly enable one continuous process on the same site, which can be less energy intensive than full depolymerisation and offers lower associated C02 emissions. CCEP, in partnership with Coca Cola Western Europe, intends to eliminate virgin oil-based PET from its PET bottles, which will see the removal of over 200,000 tonnes of virgin oil-based PET from its packaging portfolio a year. Josse Kunst, chief commercial officer at Cure Technology, said: “Polyester is one of the world’s most reversible plastics and should not go to waste. In the pilot plant phase of the Cure process, we were supported with a subsidy from the European Union and the three northern provinces of the Netherlands. “Now our ambition to create an energy-efficient solution for product to product polyester transformation will be accelerated because of this funding. The support of CCEP Ventures will enable us to start with opaque and difficult to recycle food grade PET and take the first step towards our ultimate vision of recycling all polyester, again and again.” The investment marks a step by CCEP towards 100% recycled PET for its plastic bottles and supports the transition to a circular economy for PET packaging. Nick Brown, head of sustainability at CCEP Great Britain, said: “We know that we have a key role to play in supporting the on-going development of a successful and effective recycling industry. “That’s why we’ve invested in numerous recycling technologies and partnerships over the years, from when we first began using recycled PET in our bottles in the 1990’s, to our joint venture with Clean Tech UK in 2012, to more recently partnering with Loop Industries and Ioniqa to turn post-consumer PET into food-grade recycled PET. “From later this year all of our bottles will contain 50% rPET, and this partnership with Cure marks another significant milestone in our ambition to achieve a world without waste.”

  • Innovation for sewer systems New device facilitates repair work

    Innovation for sewer systems New device facilitates repair work


    While repair work in inaccessible sewers is carried out by remote-controlled robot systems, the repairs in accessible sewers are usually carried out manually inside the sewer. Workers have to painstakingly coat fibreglass mats with reaction resin inside the sewer and to manually build it up layer by layer in the inlet of the pipes that need to be repaired – not really the nicest workplace as the odour of the sewer and the reaction resin make it a difficult task. In order to shorten the time spent in the sewer, an engineering firm has developed a new type of pressing device using Trovidur®. It makes it possible to have much of the work take place outside the sewer system. Trovidur® supports the pressing device The workers fit the pressing device with the fibreglass mats and the reaction resin already inside the service vehicle. Inside the sewer, they simply place the device at the respective inlet and, by applying pressure, press the fibreglass mat to the area that needs to be repaired. Trovidur® facilitates this pressing process at several points. A base ring with a thickness of 8 mm distributes the contact pressure very effectively during the pressing. Another 3 mm thick ring on the fitting adapts perfectly to the shape of the inlet, compensates for any unevenness and at the same time is stiff enough to hold the fibreglass mats impregnated with the reaction resin in position until they harden.

  • Kite Packaging designed a new face visor for the NHS

    Kite Packaging designed a new face visor for the NHS

    Our team of 12 engineers designed concepts for the visor and a prototype was tested locally by medics last weekend to allow production to start as soon as possible. An initial batch will reach front line medical staff in the next few days and we will produce 100,000 of the masks a week and will be able to supply them directly to help speed up supply to staff working for health trusts and organisations across the region and the UK. Gavin Ashe, Managing Partner of Kite, said: “Like many companies we wanted to help and realised that we had the capabilities in-house to design a face visor which would fit the requirements of the medics and workers who are on the front line of the fight against Coronavirus. “Once our engineers had finalised the concept and we spoke to a range of companies in the industry, they have all responded magnificently. “All of them realised the urgency of the requirement for protective ware and that we had the skills to turn around a product quickly. “One of the suppliers is Staeger in Coventry while two of the others are based in the wider region. I know there is really good work going on across this area and that the tradition of design and engineering, which is so embedded in regional industry, is well suited to undertaking this sort of work.” The visors are being supplied in kit form for the medical staff to put them together at the point of use which minimises packaging and speeds up distribution. The visors feature a foam forehead pad which allows them to fit all head sizes, and they allow for a medical mask to be worn underneath. They have so far been ordered by the George Eliot Hospital NHS Trust, University Hospitals Coventry & Warwickshire NHS Trust, Shropshire Healthcare Procurement Service (SHPS), Alliance Boots, Warwick Hospital (South Warwickshire NHS Foundation Trust), Guys and St. Thomas’ NHS Foundation Trust, North East London NHS Foundation Trust, and Royal Free London NHS Foundation Trust. We have previously worked with the Coventry and Warwickshire Local Enterprise Partnership (CWLEP) Growth Hub, and its Managing Director Craig Humphrey, said the speed of response underlined the engineering and manufacturing expertise of the area. He said: “Kite and their suppliers have been superb in their desire to help, the speed of their response, technical expertise and also their level of co-operation. There are companies across our area responding in similar way and they all deserve massive credit.”
