The global demand for fertilizers is increasing, driven by a rapidly growing population. Meeting this demand requires an intensified approach to agricultural production, where fertilizers play an important role. However, the fertilizer industry's unique challenges demand careful consideration, especially when it comes to packaging. At PAYPER, we understand the complexities involved and offer specialized bagging equipment designed to address the corrosive and dusty nature of fertilizers.

One key challenge is the hygroscopic nature of fertilizers, whether in granulate or powder form. Managing moisture becomes crucial, adding an extra layer of complexity to packaging machinery and environmental conditions. Ensuring that the filled bag maintains its nominal weight and appearance throughout its entire lifecycle, from storage to transportation and delivery, is a priority for fertilizer manufacturers. When initiating a bagging and palletizing project, factors like preferred bagging technology, bag size and material, and total hourly output must be carefully considered, all while adhering to local and international regulations.

 Categories: Product news

Advanced palletizing technologies have made palletizing bags more efficient and cost-effective. As a leading packaging line provider, PAYPER offers a variety of palletizing solutions to meet the needs of different industries. This article will provide an overview of PAYPER's 3 palletizer series, PPAL, GPAL, and RPAL and how they can improve production plant operations.


PAYPER designs and manufactures next-generation bagging lines for bulk solids: turn-key projects including dosing, weighing, bagging, palletizing and overwrapping. PAYPER has become a trusted partner for businesses seeking high-quality, reliable equipment with a commitment to technological innovation.

When it comes to automating the palletizing operation, two different product categories are available: conventional and robotic. Check out these different palletizing technologies:


  • PPAL palletizers: speedy, heavy-duty and high-productive.

This push-type palletizer is very fast, allowing high production capacities and creating fully square pallets with high stability. First, the front and side pusher system form the layers at right angles; then, each layer is compressed against the previous layer for extra stability. Push palletizers are highly flexible, allowing adaptation to different layer patterns, and are particularly suitable for valve bags and FFS bags. The highest output model in the PPAL series can palletize 2,800 bags/hour.


  • GPAL palletizers: accurate, fast and stable.

The GPAL clamp palletizer handles any type of bag, although it is particularly indicated to work with open-mouth bags as it is designed to provide the perfect overlapping of the bags. The final result is a very stable and perfectly stacked pallet.


  • RPAL palletizers: compact and versatile.

PAYPER’s RPAL palletizers are equipped with advanced robotic technology and are the most compact of all palletizing solutions. They take up very little space and therefore they are ideal for production areas with a limited footprint. They are the most versatile palletizer, as they can handle any type and size of bags including open-mouth bags, also when overlapping is required. Depending on the bag and the desired layer pattern and production, different types of grippers are available to optimize any palletizing task. They are ideal for low to medium production capacity.


New palletizing technologies have increased the production capacity, versatility and cost-effectiveness of production plants. PAYPER's PPAL, GPAL, and RPAL palletizers are designed to meet the needs of different industries and can be customized to fit specific requirements. These palletizers range offer high-speed palletizing, accuracy and efficiency, making them ideal for businesses looking to improve their operations.

Complete bagging and palletizing line for RAGT

  Published: 09/02/2022
 Categories: News Product news Projects

When RAGT, a company dedicated to the production and research of seeds was planning the construction of a new plant in Northern Spain, the company relied once again on PAYPER as the supplier of the complete packaging line for the installation.

Engineers from the two companies worked out the best solution to meet all RAGT’s requirements for the new enterprise. The final solution consisted of a fully automatic open-mouth bagger, model CSA-95, with an easy change between bag sizes and a double labelling system.

In continuation of the bagging machine, a low-level infeed palletizer, model LLG-90, was installed. The special gripping head guarantees a perfect overlapping between the bags, ensuring a very stable and perfectly finished pallet. Additionally, RAGT required a Big-Bag filling station.

Both the pallets with bags as well as the Big-Bags are conducted towards the pallet wrapper, which assures a perfect finish and protection against humidity and dust of the bags containing seeds. In this particular case, we included a labelling system, able to stick labels on all 4 sides of the wrapped pallet.

The complete line was fully tested in PAYPER’s installations before the FAT.

With the new Headquarters, situated 1 ½ hour from Barcelona, PAYPER has doubled the surface of production to some 10.000 m2.

“Our former factory had become too small and PAYPER has been looking forward to moving into our new premises”, says managing director, J.M. Godia. “It gives us the perfect setting for manufacturing and fully testing complete bagging and palletizing lines”.

Apart from the Cereals & Seeds industry, PAYPER has clients in many different sectors, such as the Chemical Industry, the Food Industry, the Animal Feed Industry, the Mineral Industry and Construction.

PAYPER exports to more than 70 countries, representing 85% of the turnover. The subsidiaries in France, Mexico, Brazil, India, the Middle East, Thailand, Russia and the Czech Republic assures local commercial and technical support.

Case Story: Fully Equipped Bagging Machine, made for the Versatile Conditions in the Pet Food Industry

  Published: 26/11/2020
 Categories: Product news Projects

Watch the video


Our client needed a fully automatic, modern and top-performing bagging machine with all the features to face the actual and future demands in the Pet-Food sector.

They approached us because they had experienced considerable growth and they needed to expand their production capacity. Together we designed their new bagging-line.

Products and bags

When we first discussed this new Pet Food bagging project, it was clear that the client needed a very flexible solution. Like most Pet Food manufacturers, the list of different products was very long: More than 60 products and different kibble sizes that should be packed in bags from 5 to 20 kg.

We analysed the wide spectrum of bag types and materials: Laminated aluminium, polyethylene and laminated woven polypropylene bags. Some of them were equipped with a zip or a slider and some with Velcro-closure. Some should be filled from the mouth and others from the bottom, including double bottom bags.

The required rate was to match the extruder’s capacity of 10.000 kg per hour.


Our recommendation was the CSA MD-105, a truly versatile solution, that would adapt perfectly to all these different needs.

It was equipped with a multiple empty bags magazine that confers great autonomy to the installation. The client wanted to print the batch number and the expiry date on the empty bag. We fitted a thermal printing station that ensures a perfect marking due to the exact stopping position of the bag.

To guarantee outstanding precision while maintaining the high-speed filling rate, we agreed on a double dosing and weighing system with vibrating channel.

When a bag is fitted with a zip or a Velcro closing, that is unintentionally closed, the filling mouth has a special feature, that opens the bag without damaging the bag’s external decoration. 

A de-aeration system evacuates the air in the bag before the final closure by welding. Optionally we have left one station open in the CSA MD 105. At a later stage, we can fit a probe with a double function: It empties the bag of air and it can fill it with an inert gas.

Before the final closing of the bag in the welding station, an alignment system to level the bag’s mouth assures a perfectly positioned welding on the very top of the bag with an excellent finish. The welding station is capable of making a double welding if required.

The hygienic aspect has been particularly addressed by means of the integration of an automatic air cleaning system. The dosing and weighing system together with the connecting hopper and the bagging mouth are designed to ensure that there is no retention area. Therefore, the automatic air cleaning cycle ensures perfect cleaning of all parts that come in contact with the product. All PAYPER machines can be accessed from all four sides, including from the electrical cabinet, a feature that makes maintenance and cleaning very easy.

4 tried and tested Precision Dosing and Weighing systems from PAYPER

  Published: 18/09/2020
 Categories: News Product news

When bagging a bulk product, the accuracy of the weighing system is of extreme importance. A wide range of products are of high value and, at the time of bagging, even the smallest deviation from the nominal content may result in significant economic losses.

PAYPER’s R&D department has developed 4 different electronic dosing and weighing systems. They are all manufactured in-house, which means that we fully control the quality and performance of the final dosing and weighing system.

We have a Dosing and Weighing system suitable for bulk-products of any kind: Fine Powder of <120µ, Coarse Powder from 120-500µ and Granules of more than 500µ. Whether the product is free-flowing or non-free-flowing, the process of dosing and weighing is carried out to the highest accuracy without sacrificing the performance speed of the bagging machine.

The inside surface of the dosing system is smooth, without any retention area. This prevents the product from getting stuck in a corner.

Particular attention has been given to providing easy maintenance: Easy access to the inside of the dosing system thanks to the removable covers on all four sides of the dosing system. When open, the smooth inner surface of the dosing system ensures easy cleaning. In addition, we can supply automatic cleaning systems with air, specially tailored to each client’s particular needs. All weighing systems can be delivered in Stainless Steel for hygienic purposes or for the handling of corrosive products. ATEX versions of all Dosing and Weighing systems are also available.



The CGV is a dosing-system which combines gravity feeding with a vibrating channel. This is typically used for semi-free flowing products such as blends or kibbles of Pet-Food. The coarse filling is performed through a dosing gate and the fine dosing is handled by the vibrating channel. This system’s weighing range is from 5 to 50 kg with speeds of 600 weighings/hour.

Watch the video here. Read more about dosing/weighing here.



Our CT belt conveyor system is also made for semi-free flowing products like seeds, feed pellets, and so on. The dosing and weighing are carried out by means of a unique dosing gate which controls both the coarse and fine dosing. The weighing range is for bags of 5 to 50 kg and speed of up to 600 weighings/hour.

Watch the video here. Read more about dosing/weighing here.



This dosing and weighing system works by means of gravity feeding combined with a special dosing gate that takes care of both the coarse feeding and the fine dosing. It is ideal for free-flowing products, such as grains or semolina and it is available in two versions:

With a servo-driven motor for high speed, offering up to 2,600 weighings/hour or with pneumatic control for up to 800 weighings/hour. Weighing range for the two versions is 5 to 50 kg.
