PAPER PULP MOLDING MACHINES

ABOUT THE COMPANY

TRIDAS ranks among the leading European moulded fibre producers. At present we manage three production facilities covering a total area of 22,000 m². Since 2018 we have had 9 fully automated production lines owing to which we can reach high productivity and production variability. The production process is supervised by the Quality Control Department in compliance with the ISO 9001, ISO 14001 and ISO 45001 certifications. Our advantage is we have our own design and technology department which is involved in developing end products and production moulds. Our own development, modern production technologies as well as our vast warehouses guarantee we can provide our customers with high-quality and flexible services. With regard to increasing productivity and quality requirements, in 2009 the Development Department was extended to include a division of our own production lines. Since 2010 all the production technologies used in our company have been designed and manufactured by us. Combining our own development and manufacture means our production processes have become highly optimized resulting in the long-term reliability of our production lines. In 2019 we established TRIDAS Technology – a new production and sales division for moulded fibre production lines.

WHY MOULDED FIBRE?

The worldwide growth in consumption results in a higher production of disposable packages or disposable tableware. Every person on the planet produces an average of 500 kg of waste a year, which is 3.5 billion tonnes of waste a year. From the long-term point of view, this is unsustainable and it is necessary to start managing all production as a circular economy. One thing that is crucial for sustainable development is that the materials used are mutually separated into two independently circulating flows which are managed by a different logic. The first one operates with materials of organic origin which are easily degradable and there is no problem to put them back into the biosphere. The other one operates with synthetic materials. One of these possibilities is the use of moulded fibre, which is made of pure virgin (wood) pulp or recycled wastepaper and which is 100% recyclable. By using it, the amount of waste and thus the impacts our activities have on the environment are minimized through reduced NO_x and CO_x emissions..

Moulded pulp packaging has been used for more than 100 years. The first references to pressed fibre date back to 1903, when Martin Keyes of Maine, USA, started making formed boards for pastry. Due to formed fibre’s excellent ability to absorb shock, in 1931, the idea emerged to put fresh eggs and transport them in special packages made of moulded fibre. In the 1990s it started to be used as industrial and design packaging. Moulded fibre’s indisputable advantages are its recyclability, sustainability and degradability in soil.

ABOUT OUR PRODUCTION LINES

TRIDAS’s production lines represent an ideal quality to price ratio. Our production technologies are supplied solely with European components. Owing to this we guarantee warranty and post-warranty services. As a Czech producer we provide European quality and safety standards. All pipe distibution and components coming into contact with water or pulp are made entirely of stainless steel. The entire production line is supplied as a single unit, which includes pulp preparation, tray production, the subsequent finish and a central control system.

The primary input material for moulded fibre is recycled paper. However, it is also possible to use all other pulp- or cellulose-based materials such as cardboard, newspapers, tissues, writing paper, primary wood pulp or pulps made of agricultural products. Depending on the input material used, the wall thickness and the surface quality, we divide the production technologies into industrial, thermoforming, and table ware.

INDUSTRIAL LINE CL660 OR CL1150

This production line is designed mainly for industrial packages such as packaging for furniture, steel components, machine parts, engine parts, electronics, agriculture, etc. The primary input material is recycled cardboard, newspapers, tissues or combinations of these. It is also possible to use pulp made of residual agricultural products such as hops, corn, grain, peat, etc. Production process: fibrillated and cleaned paper is sucked onto the mould and then it is transferred to the drying belt. After drying, the product is placed on pallets. In order to attain a higher surface quality, the product may be repressed and trimmed.

Max. product size	1200 x 1000 mm
Wall thickness	1–7 mm
Production capacity	up to 250 kg/h (up to 23 mil. pcs/year)
Power consumption	100–180 kWh
Natural gas consumption	25–55 m3/h
Water consumption	150–500 l/h
Minimum required area	750 m2

PAPER THERMOFORMING LINE KP750

This production line is designed mainly for manufacturing trays in complex shapes or if a higher emphasis is placed on the surface quality. During the production process the wet trays are hot pressed to smooth the surface. Such trays are mainly used for premium electronics, the cosmetics or car industry or components in complex shapes or those that are small. The input material is mainly pure pulp, testliner, kraftliner or tissue. Production process: fibrillated and ground paper is sucked onto the forming mould. Then it is transported into the drying and pressing mould. The production line is supplied as a single unit, i.e. pulp preparation plus 4 to 12 KP 750 machines.

Max. product size	600 x 500 mm
Wall thickness	0.4–1.5 mm
Min. number of machines	4 x KP750
Max. number of machines	12 x KP750
Production capacity of KP750	13 kg/h (up to 6 mil. pcs/year)
Max. production capacity	155 kg/h (up to 72 mil. pcs/year)
Power consumption	60–80 kWh 1 x KP750 700–950 kWh 12 x KP750
Water consumption	130 l/h to 400 l/h
Minimum required area	300 m2

TABLE WARE LINE KP DUO930

This production line is designed mainly for making paper plates and paper cup lids. During the production process, the wet plates or lids are hot pressed to smooth the surface. Lids and plates made using this technology are water resistant and they can fully replace plastic ones. As these products are designed for direct contact with food, the input material is always virgin pulp. Recommended pulp types are bagasse, bamboo, eucalyptus, soft wood and hard wood. Production process: fibrillated and ground pulp is sucked onto the forming mould. Then it is transported into the drying and pressing mould. The last production step is trimming the edges and cutting out the holes (paper lids). The production line is supplied as a single unit, i.e. pulp preparation plus 4 to 8 KP930 machines

Max. product size	850 x 850 mm
Wall thickness	0.4–1.0 mm
Minimum number of units	4 x KP930
Maximum number of units	8 x KP930
Production capacity of KP930	21 kg/h (up to 45 mil. cup lids/year, or 8.5 mil. plates/year)
Max. production capacity	168 kg/h (up to 360 mil. cup lids/year, or 68 mil. plates/year)
Power consumption	90–120 kWh - 1 x KP930 700–1000 kWh - 8 x KP930
Water consumption	210 l/h to 450 l/h
Minimum required area	500 m2

Since 2013, TRIDAS has been a holder of European patents for paper lids for hot drinks (with drinking holes) RCD 002254581-0001 and paper lids for drinking straws RCD 002254581-0002. When purchasing our production line and moulds for the manufacture of these lids, the buyer will be granted a licence to manufacture paper lids with a maximum volume equal to that of the acquired production technology.
