Different systems and packaging materials can be used for the filling and packaging of reactive adhesives, resins and glues, e.g. PUR hotmelt. The choice depends primarily on factors such as the production volume, the specific requirements of the product and its final application. In the particular case of PUR hotmelt, the question arose as to whether the existing and complex packaging concepts of 2 kg containers, 1 kg containers or small cartridges (e.g. for Holzherr edging systems) in cylindrical filling form with a smooth surface finish could be filled more efficiently and cost-effectively in flat film.

Thanks to our innovative approaches and technologies with vertical filling and automated cooling concepts, our flexibility and broad expert network of qualified partners, we are able to respond to such customer inquiries with a wide range of requirements. We can often use existing technologies as a basis and offer a tailor-made solution by means of individualized adaptations.

One of our customers approached us with a specific requirement specification to replicate their existing production process for 2kg units in candle form and to optimize the filling process, e.g. reduction of work steps, avoidance of stringing, etc.. Although the primary objective was to optimize the filling process, we did not look at it in isolation, but rather as part of the overall process and critically examined it in order to exploit the greatest possible optimization potential for our customer. Due to our many years of experience in hotmelt filling, there was no question for us that simply implementing the specifications would not bring maximum efficiency and productivity for our customer.

Based on the specific product requirements, Vermee Packaging Technology translated these into a basic concept with initial individualized technological components. These approaches were implemented and optimized as part of pragmatic filling tests. In close cooperation with our team of experts and the customer, we optimized the concept, tested it further and finally adapted it to the individual product and production requirements.

The result of this collaborative partnership is an optimized, efficient and packaging-reduced production concept. It enables flexible and string-free filling of PUR hotmelt, packaged in cost-effective flat film in various units with at least double the output compared to conventional processes. In addition, there are low personnel costs due to the high degree of automation and, if required, an automated cooling unit. The automated process sequence has also greatly reduced the error rate for the end customer.

We at Vermee Verpackungstechnologie are proud that we have not only simplified the packaging process for our customers but have also been able to make a contribution to the entire industry for filling PUR hot melt adhesives thanks to the various customizations.

As part of the filament-free filling logic of PUR hotmelt, a further filling form, the “PUR hotmelt pouch”, has been developed. These are small units, e.g. 50g, 100g, 200g, 400g, etc., which can be filled either individually or as a “PUR-HM garland” in 10x 50g units. The packaging form of the PUR-Hotmelt Pouch is a strong alternative to the previous PUR-HM granules, which are produced in cans for single use. With the PUR-Hotmelt Pouch, the end user can easily make additional doses without creating unnecessary residual product and waste. The advantage of this filling form is the air-free and very efficient filling using very little packaging material. With the PUR hotmelt pouch, the product is simply packaged in cost-effective flat film in an automated process. At the same time, the products are cooled quickly so that production can take place in a space-saving area.

Another effect of using hotmelt pouches that should not be underestimated is the significantly lower amount of waste compared to conventional packaging materials such as hobbocks, hard-shell cartons, cans or cartridges. This has a positive effect on the environmental balance and the reduction of your company’s CO2 footprint.
