Fachpack – Film + Paper = Trade Fair
The Fachpack trade fair, one of the starting time live meetings took place in the German language trade fair mural at the finish of September after the enforced intermission in 2022 and early 2021. It became clear that the demand for recyclability – regardless of the material – is continuously creating new material solutions. Paper-based packaging materials are increasingly being 'upgraded' for a wide range of applications. Film manufacturers nowadays new mono-material solutions for optimized recyclability of flexible packaging. And – chemic recycling is being placed in many places and presented as a future topic by some players in pilot projects.
Paper-based materials are indispensable
For Mondi, a neutral argument is important when it comes to the question of newspaper or plastic. The value chain and the production to be packaged are so individual for each customer that no more often than not valid statement can be made as to which packaging material should exist preferred. In particular, the environmental impacts of both packaging materials must be considered as comprehensively every bit possible. This is but possible if a specific application is defined and a consummate lifecycle assay (LCA) of the alternatives paper or plastic is carried out. Currently, such a written report is being conducted for kraft paper in the area of pallet protection. Instead of a film wrapping, a paper wrapping could as well be used. The results of the LCA for Mondi'due south project with the Italian auto manufacturer ACMI are to be published in November.
Constantia Flexibles also presented a broad range of products at the trade off-white. Its comprehensive mono-material PE range with the EcoLam line, the newly presented EcoVer fabric line as well equally the products from the EcoPaperPlus line go far clear that the one right packaging is not achievable. EcoVer is a mono-PP solution, bachelor in different barrier levels, thermal resistance included. The packaging solution features an enhanced outer layer combined with a sealing layer that starts to seal at low temperatures to allow a broad sealing window. The material in mono-PP structure is recyclable in the mixed polyolefin stream.
Enhanced recycling options with monomaterials
In addition to iv new BOPE-monomaterial-solutions, Jindal Films Europe set a focus on solutions to support a switch from hard-to-recycle laminates containing, for case, PET, alufoil, or newspaper to mono-material mechanically recyclable PP-, PE- or PO- (polyolefin') based laminates for flexible packaging. One example for these applications is the improved rut resistant OPP film to supercede PET films to address
the needs of retort sterilization applications. The new developmental Bicor MR100 for the outer web in antiphon sterilization applications should help to minimize the shrinkage and visual distortion during heat sealing and autoclave operations when using PP-based retort laminates.
Südpack, Ochsenhausen, Germany, besides, presented its recyclable mono-materials with its Pure-Line production family unit. The Pure-Line offers solutions made of PP, PE, and PET, which are classified as recyclable in many countries. It is possible to optimally design the material structures to run into the requirements of a wide variety of applications. The spectrum ranges from thermoforming films to lidding films and high-bulwark films for the production of doypacks. Another key focus was on packaging print – thanks to the newly developed SPQ technology (Sustainable Print Quality), significantly reducing the consumption of ink, solvents, production waste and free energy while simultaneously improving print quality is underway .
SPQ – a milestone in flexo press
Within the scope of a joint project with Goldstein Käsereien Bayerwald, Südpack successfully reduced ink and solvent waste by more than 60% in the implementation of several printed images by applying SPQ technology. It was likewise possible to farther optimize the print quality. "This is an of import stride towards a much more sustainable time to come," remarked Josef Wagner, senior manager of Sales and Marketing for the cheese specialist located in Cham in eastern Bavaria.
Südpack'south SPQ technology uses a set color palette. In the pre-press phase – much like with offset or digital press – all designs are automatically and reliably prepare up using a standardized color palette. "The implementation of consistent process stability is the indispensable basis for optimizing efficiency, sustainability and quality. It was also the greatest challenge posed by this evolution project," summarized Carolin Grimbacher."
Machines for moving picture and paper
One option to bargain with the option betwixt newspaper and film packaging was found at Syntegon. The company presented an integrated system consisting of a vertical SVE 3220 DZ form, fill and seal motorcar and an Elematic 2001 WAH case packer that produces stand up-up pouches for pasta from recyclable newspaper and places them in aircraft cases. As well using mono-materials for all common handbag styles, the SVE 3220 DZ processes paper to package products in pillow, block-bottom or doy bags with a stand-up top of up to 311 mm. This makes it suitable for packaging confectionery, also as baked appurtenances, cookies, and powdered products.
The transformation from plastic packaging to paper-based packaging is also a task that has been started among users in the Indian marketplace, they said. A number of enquiries have already been received virtually paper packaging, which is being tested primarily on the horizontal form, fill up and seal machines at the Syntegon production site in Verna in Goa.
Another focus in the machinery sector is on forming paper-based containers. Syntegon is pursuing this in a cooperation with BillerudKorsnäs – "FibreForm is the natural alternative where plastic has been the norm. Allowing for upwards to ten times deeper embossing than regular paper, resulting in 3D furnishings that make an impact," explains Simon Johansson, Project director at BillerudKorsnäs, Sweden. The new packaging system is ideal for individual portion packs and products that would normally be packed in blisters . In addition to cosmetics or samples, Shaped Paper Pods tin be used to package dry, chunky or viscous food thanks to a sparse barrier layer. Be it spreads, margarine or biscuits in newspaper trays – the new TPU paper forming machine offers manufacturers a range of filling and sealing systems for sustainable packaging at an output of upwards to fifteen,000 Shaped Paper Pods per hour.
The automobile manufacturer Koch Pac-Systeme, Pfalzgrafenweiler, Deutschland, has established itself on the market as an adept for blister packaging. There, besides, newspaper is the topic of the mean solar day. With a formed paper-thin packaging – in the trade fair example for razors – the company was able to prove that even demanding geometries with convex and concave elements, steep wall angles and small radii, previously typical in the blister foil spectrum, can exist realized in a one-stride 3D forming process fifty-fifty with flat paper blanks.
Kiefel, Freilassing, Germany, is also opening its range to paper forming. Beingness a specialist for plastic thermoforming and joining applied science, the company opened up the additional business surface area of fiber thermoforming internationally. "We are pleased to be able to present the manufacturing process on a sit-in organisation. In add-on, we are providing an insight into our research and development processes also equally our auto solutions," says Uwe Heer, Area Sales director Packaging.
Kiefel offers two complementary organisation – the Natureprep KFP for loftier quality stock grooming of natural cobweb lurid and the Natureformer KFT serial, on which various fiber products, e.yard. bowls, cups, secondary packaging for electronics, coffee capsules or bloom pots tin be manufactured. The raw textile for cobweb products is pulp or paper dissolved in water. This is shaped, pressed, dried and converted into dimensionally stable packaging that can exist recycled in the newspaper wheel or even composted. This means they offer an alternative to plastic packaging, depending on the application.
Chemical recycling in sight?
Sustainability is the large keyword that could be understood non but every bit the motto of the off-white simply also as a tendency within the industry. With the keywords mentioned, it was possible to depict a line between the use of paper-based solutions that serve valuable recycling cycles and mono-material films that are increasingly beingness brought onto the market precisely for this purpose.
Another strategy for obtaining new raw cloth from plastic residues was positioned rather casually by various players. Südpack, for case, presented a pilot project on chemical recycling in a joint venture with Carboliq, Remscheid, Frg, which uses keen to produce polymers from residual plastics that should take the same properties as virgin material.
Especially for plastic fractions whose degree of contamination is too high for mechanical recycling, chemic recycling every bit an option can save the valuable plastic from nutrient employ from thermal recycling – i.e. incineration. Chemical recycling was likewise visible as a keyword in the trade fair presence of another exhibitors – it remains open in which time horizon and which options will actually be opened up with it.
