A packaging machine for nuts and dried fruits is used for packaging products such as various nuts, dried fruits, seeds, legumes, and more. These packaging machines are available in fully automatic industrial types, semi-automatic workshop types, and manual (home) types, and they can be purchased and customized accordingly. Packen Company manufactures various sealing and vacuum machines equipped with Modified Atmosphere Packaging (MAP) technology, which increases the product’s shelf life.
Nut packaging machines usually include various systems such as checkweighers, container loaders, UV tunnels, fillers, automatic row organizers, vacuum and gas injection systems, traffic tables, and more.
These machines can package products in various attractive forms, including plastic, nylon, foil, plastic containers, sealed packages, and more. Typically, these machines are used not only for nuts but also in other food industries.
Method MAP: The Best Method for Packaging Nuts
The best environment for storing nuts is a dry, cool, and completely sealed environment. Heat, humidity, and secondary contamination cause these products to spoil.
The growth of various molds in nuts due to improper storage conditions can pose irreparable dangers to the consumer. One type of fungus that grows in these products is Aspergillus, which produces aflatoxin, a highly harmful toxin.
Aspergillus is an aerobic microorganism, so using Modified Atmosphere Packaging (MAP) can remove oxygen from the reach of this microorganism, thereby preventing the growth of this fungus and ultimately the production of aflatoxin.
To increase the shelf life of the product, it is necessary to prevent the growth of bacteria, yeasts, and molds. Some of these issues can arise during product preparation or packaging, so sanitary standards such as minimizing hand contact by operators, ensuring a hygienic environment and containers, etc., must be fully observed to minimize food poisoning.
Another challenge in storing dried fruits is infestation and insect growth in the product. Producers who package their products in bulk often suffer because pest infestation occurs in a very short time, preventing them from selling their products and causing financial loss. By packaging products using the tray sealer machine and the MAP method with partial vacuuming (removing oxygen inside the product and injecting nitrogen gas), it is possible to completely prevent pest infestation along with increasing shelf life.

Packaging Containers for Nuts
Dried fruits are typically packaged in various types of containers, including plastic, metal, paper, and plastic pouches. Nut packaging should enhance hygiene, shelf life, and product quality.
For nut packaging, protective polymers are commonly used to protect the product from moisture, oxygen, and secondary contaminants. Cardboard and paper packaging can also be used for dried fruits; these are environmentally friendly but may not significantly improve shelf life or maintain the organoleptic properties of the product.
Packaging in plastic containers with vacuum sealing and nitrogen gas injection not only protects the product from moisture and environmental contaminants but also helps preserve the initial quality of the product for a longer period. Dried fruits should be stored in a dry and cool environment. Additionally, the packaging should be transportable to prevent damage during shipping.
It is recommended to use reputable and experienced companies for nut packaging to achieve the best results in maintaining quality and extending the shelf life of dried products.
Types of Nut Packaging Containers:
Bags or Pouches: Polypropylene bags are used for packaging dried fruits, including nuts, almonds, walnuts, etc. These bags are popular due to their ease of packaging, water and moisture resistance, lightweight nature, and affordability.
Containers for Nuts:
Cans: Cans are used for packaging nuts, including various types of nuts, dried fruits, legumes, and more. They are popular due to their durability, long shelf life, resealability, and ability to preserve the product’s qualities.
Foil: Foil is used for packaging nuts, including nuts and dried fruits. This type of packaging is appreciated for its attractive appearance and its ability to protect the product’s properties.
Vacuum: Products are placed into nylon bags and then vacuum-sealed, giving them an attractive and compact appearance.
Plastic Containers: Packaging in plastic containers using vacuum sealing machines not only has lower overall costs compared to other packaging methods but also enhances the visual appeal, hygiene, and shelf life of the packaged product. With vacuum sealing machines, there are no limitations on the shape and size of the container; the machine’s mold is designed and built according to the specifications of the desired container.
Attractive-shaped containers can enhance the appearance of dried fruit packaging and positively impact sales. Packen, with its expertise in the packaging machinery industry, can provide customers with custom molds for container production.

Packaging Considerations for Various Nuts
Almonds
Almonds are commonly recognized as a type of nut, although they are technically a seed. They are rich in protein and fiber and have a low sugar content. Almonds are packaged as nuts in plastic containers, plastic wraps (pouches), or cans. In some parts of the world, they are consumed as snacks, so their packaging needs to be attractive to consumers. Almond packaging machines are fully automated to ensure that the packaging is done effectively and efficiently.
Cashews
Cashews are nuts/seeds from the cashew tree. They are rich in nutrients that benefit the body, especially the heart, due to their healthy fats. Cashews are also a good and easy snack, and their popularity is increasing, particularly among health-conscious individuals. Having cashew packaging machines can help increase the efficiency of cashew packaging.
Hazelnuts
Modified atmosphere packaging controls the environment to enhance the shelf life of hazelnuts and maintain their quality. Studies have shown that this type of packaging addresses issues related to high levels of peroxide, rancidity, acidification, and unsaturated fatty acids. Ultimately, organoleptic properties are also preserved in a low-oxygen environment, extending shelf life for at least a year.
Pistachios
Long-term storage of pistachios is a key factor in the nut industry, but it comes with challenges. The risk of aflatoxin contamination is higher for pistachios compared to other nuts. On the other hand, pistachios are less prone to oxidation than other nuts, resulting in a lower ratio of unsaturated to saturated fatty acids. Other factors that enhance quality during storage include removing oxygen, controlling pests through fumigation, using controlled atmosphere or low temperatures in pest-proof storage and packaging.
Walnuts
Storing walnuts requires special attention to the impermeability of the packaging. Walnuts need protection from oxygen and moisture transfer. Due to their high oil content, walnuts spoil quickly when exposed to oxygen. Optimal storage conditions are ensured with low pressure and low oxygen levels, as proper packaging addresses issues like density, acidification, oxidation, and contamination.

Home Nut Packaging Machines
A home nut packaging machine, as the name suggests, is designed for packaging nuts and related products in a home or small business setting. These machines are available in two types: manual and semi-automatic. For free consultation, you can contact us at Packen.
Most home businesses perform packaging manually using a manual process. Typically, a team of 3 to 4 people fills the bags, then weighs them, and finally seals them with a machine.
A tabletop sealing machine is used for packaging in plastic containers in small capacities, such as for retail and home use. This process is done manually, and the machine also allows for the use of printed films.
Challenges and Difficulties of Home Nut Packaging
The process of packaging nuts and dried fruits at home faces several challenges:
Human Resources: There is a constant dependency on human labor, and it is not always available. Absenteeism during peak times is a persistent concern for most producers.
Weight Control: There is often a lack of precise control and monitoring of the net weight of dried fruits in the bags, which may lead to inconsistencies. This creates problems in sales, as retailers and distributors frequently complain about weight variations and sealing issues, making it challenging to increase sales.
Limited Capacity: Manual equipment restricts the ability to scale production. As long as your production levels are within 500 to 1000 packages per day, simple manual systems can support your needs without major issues. Starting with manual systems is cost-effective, and setting them up is straightforward. The simplicity, quick setup, and low cost of manual packaging machines are advantages of this method.
However, this approach becomes a bottleneck as production volumes start to increase. If you want to boost the speed of work in your home or small business and produce higher volumes, you can use semi-automatic machines from Packen. This approach provides a significant increase in automation while still being reasonably priced.
In a semi-automatic machine, the packaging process is automated, with only the placement of nuts into containers and some other tasks requiring human intervention. Using this machine allows you to package dried fruits with high quality and hygiene, making them suitable for sale in local stores, online, and elsewhere.
For advice on pricing and selecting the best machine for your needs, you can receive free consultation from our experts. If your business is larger and your production volume is high, you should use fully automatic machines, which will be discussed further. Feel free to contact us for guidance, and we will be happy to assist you.
Industrial Nut Packaging Machines
Industrial nut packaging machines are typically either fully automatic or semi-automatic and are used for packaging various types of dried fruits in both small and large volumes. These machines operate automatically, providing high-speed and precise packaging. They generally include components such as an input conveyor belt, weight control system, automatic container feeder, filler, vacuum and gas injection system, automatic row aligner, jet printer, automatic lid applicator, and a traffic table (turntable). The design of these machines emphasizes hygiene, safety, efficiency, and speed to meet the packaging needs of different dried fruits.
Packaged nut producers prefer machines that allow for easy and precise weight adjustments without the need to change parts and offer straightforward operator training.
A good nut packaging machine should be able to:
- Remove excess material from the packaging
- Reduce packaging time
- Provide precise weight adjustments
- Ensure hygienic packaging
If the net weight in each package is less than expected, it can lead to dissatisfaction among distributors and sellers. As a result, producers might need to add more product to each bag to address these concerns. These small excess amounts distributed as extra gifts on each package can accumulate significantly over the year, impacting overall profitability.
Therefore, at Packen, we use precise measurement systems in our machines to ensure the highest accuracy in weighing and the highest quality in packaging.
