Overview of many filling goods in the nuts and nut mixes sector

Nut filling in the best hands

"Benefit from high speeds with minimal residual oxygen values, even with high filling quantities."

Dirk Quabach, Senior Sales Manager

Nut filling made easy

High performance at any filling volume

thanks to smart discharge management of the multihead weigher

In combination with multihead weighers, our pouch packaging machines achieve impressive cycle rates – even with large filling volumes. Intelligent discharge management ensures a continuous output of ready-to-sell pouches, easily compensating small delays at the multihead weigher. Even with filling volumes ranging from 500 g to 1,500 g, efficiency remains high.

Product protection

by minimizing product breakage

Almonds, macadamia nuts, walnuts, or Brazil nuts – every nut variety has different characteristics. However, what they all have in common is their high value and fragility. To ensure that the premium quality of your products maintain their high standard all the way to your end customer, the pouches are filled with extra care. Short drop distances minimize breakage and protect your nuts and nut mixes on their way into the pouch.

Extended shelf life

thanks to minimal residual oxygen levels

Using our proven gas treatment, we reduce the residual oxygen in the bag to a minimum of typically 2 – 5% – ensuring the longest possible shelf life and freshness.

Quality paired with top-speed

High speeds and output

High speeds and output Achieve consistently high speeds on our pouch packaging machines, even with large filling volumes. Depending on the specific dosing requirements, output rates ranging from 40 to 210 pouches per minute are possible. For the nut industry, we recommend production on single (simplex) to triple (triplex) machines. Quick and easy format changeovers reduce downtime for our machines significantly and ensure higher output rates as well as a higher machine availability.

Precise and efficient filling

Nuts are typically filled using multihead weighers, which combine precise weight control with high speed. During the filling process, the nuts or nut mixes are handled with utmost care to prevent product breakage and quality loss. To reduce the residual oxygen to a minimum, the product is additionally protected by our unique gas treatment. This guarantees the freshness and quality of the dried fruit and ensures a longer shelf life.

Quick and easy format changeovers in <15 minutes

Our machines enable partly tool-free format changeovers in less than 15 minutes, depending on the machine type. Using the integrated recipe management system, production and machine parameters for individual products and formats can be conveniently loaded via the HMI. This reduces downtime and increases machine utilization as well as productivity – especially during frequent product changes. We offer various levels of automation to make changeovers particularly quick and easy.

Quick and easy cleaning

For quick and thorough cleaning of the machine and and parts that come into contact with the product, we offer well-designed solutions, either using dry cleaning or wash-down for allergen-free cleaning.

Nuts - packaged efficiently, gently and precisely

Unique pouch quality, for which our machines have stood for years.

We adapt the pouch packaging machine individually to your pouch.

Stand-up bottom

An additional fold in the packaging material creates a pouch's stand-up base. This very stable base construction enables the pouch to stand independently on a flat surface. In addition to the primary function of being able to stand on its own, the stand-up bottom and the resulting bottom fold give the pouch a higher filling volume than a flat pouch. The bottom shape can usually be round, as in doypacks, or trapezoidal, as in deltapacks.

Zipper

A so-called zipper reclosure is often used to make the pouch reclosable. This zipper consists of two plastic lips that can be pressed together, pulled apart, and sealed into the top area of the pouch. This makes it possible to reclose the pouch after it has been opened for the first time and maintain the filling product's freshness to a certain extent.

Tear opening notch

The tear-opening notch is a punched hole in the upper side seal seam of the pouch. This punching makes it easier for the consumer to tear open the pouch without tools and consume the contents. The tear-opening notch is usually designed as an incision or punched-out arrowhead.

Side sealing seam

The side sealing seam is the two sealed pouch edges and closes it in this area. The side sealing seam requires exceptional quality and strength. Its width can be freely selected according to the length of the pouch. Depending on the contents, filling quantity, and size, the pouch must be able to withstand various pressures and sealing requirements. Optical and functional sealing patterns, such as cross and ripple patterns, can also be created in the sealing seam.

Top sealing seam

A top sealing seam permanently closes the pouch after filling. The side sealing seam requires exceptional quality and strength. Depending on the contents, filling quantity, and size, the pouch must be able to withstand various pressures and tightness requirements. In addition to the technical requirements, wider top sealing seams are often produced to give the pouch a corresponding appearance. Additional functions like hanging devices (euro hole or round hole) are integrated into the top seam.

Sealing seam quality

Sealing seam quality is one of a pouch core criteria. It must meet a wide range of quality and functional criteria. Thanks to our innovative and high-quality sealing technology, our machines can guarantee consistently high sealing seam strength over the long term. This also applies to different packaging materials and mono-materials.

Processability of mono-materials

All of our new machines can process recyclable mono-materials as standard. Thanks to innovative unwinding and sealing technology, new and thinner films and papers can be processed at the same quality and speed.

Filling level

To minimize packaging material and costs, but also from a sustainability perspective, keeping the space between the product fill level and the top seam as small as possible is essential. Some technical processes, such as tightening before head sealing, require a certain amount of space in the headspace of the pouch. Headspace steaming, intended to counteract possible pouch inflation, also requires a certain amount of free space in the head area of the pouch. We are happy to help with the optimum design of the pouch dimensions depending on the intended filling quantity and filling level.

Hanger hole

The hanger hole is primarily used for easy placement on the shelf at the point of sale. The pouches with a (Euro) hole are pushed onto the shelf bars. The choice of hanger hole is up to you and is realized via a separate punch in the pouch packaging machine.
