The term 'dried fruit' includes all fruits that are dried to increase their shelf life so they can be consumed for a longer period. However, simply drying fruits is not sufficient for preserving their quality. Therefore, dry fruit packaging has been employed to address this issue.
Dried fruit packaging specifically refers to maintaining dried fruits in healthy and hygienic packaging, including pouches, trays, and boxes. These packages have strong barrier properties against external elements such as moisture, air, temperature, etc., which otherwise could damage the texture and taste of dry fruits.
West Asia Steel Company is one of the manufacturers of dried fruit packaging machines. In this article, we will explore the methods of dried fruit packaging and the usage of packaging machines.
Advantages of Packaging dry fruits
Packaging dried fruits offers multiple benefits such as preserving the quality of the dry fruit, customer satisfaction, and increasing product shelf life. All these features are explained below:
Quality Preservation
Packaging dried fruits with a strong barrier against moisture, contamination, oxygen, and light protects the quality of your dried fruits. This ensures that all essential nutrients, color, and odor present in the dry fruits are preserved.
Extended Shelf Life
Packaging, by removing oxygen from the packages and injecting nitrogen into them, ensures the shelf life of dry fruits. Therefore, products inside the packages can remain intact for a longer period without spoilage, microbial effects, oxidation, and other detrimental factors.
Reduction of Waste
Most unpackaged or poorly packaged dried fruits get spoiled during transportation. However, when the same dried fruits are properly packaged in bags and containers, there is less likelihood of them being wasted or spoiled.
Customer Satisfaction
Through the packaging of dry fruits, you can provide a wide range of information to customers about the company, product, nutritional value, expiration date, ingredients, etc.
Convenient Use
Packaging dried fruits in flexible packages such as specially shaped plastic trays and sealable bags makes their usage easy. This also attracts the attention of buyers.
Dried Fruit Packaging Using Modified Atmosphere Packaging (MAP)
Packaging using the modified atmosphere packaging (MAP) method is carried out by packaging machines called tray sealers (seal vacuum). In these machines, dry fruits are placed inside plastic trays, and a film or cellophane of the desired material by the manufacturer is sealed onto the tray.
One of the most important parts of tray sealer machines is the mold system of the machine. The main structure of the molds in the tray sealer machines of West Asia Steel Company is uniform casting. The significance of this matter becomes apparent during packaging using the modified atmosphere packaging method. In this method, vacuuming is first performed to remove the air inside the packaging, and then nitrogen gas is injected into the package. This operation must be carried out under vacuum conditions; otherwise, the error rate increases, and the desired result is not achieved.
For performing vacuum and injection of gas without error, the mold system must be completely impermeable. This means that during vacuuming, air should not penetrate into the mold, and during gas injection, the gas should not escape from the internal chamber of the mold. This is achievable when the mold is a single piece and not connected by screw and nut because molds by screw and nut will become permeable over time due to loosening of the screws and bolts.
Types of Packaging for dry Fruits
There are various methods for packaging dried fruits, which we will explain below:
Stand-up pouches and gusseted bags
Stand-up pouches are durable bags that can be used for storing dried fruits. They are made of multi-layer films including aluminum foil and plastic, providing excellent protection against sunlight, moisture, heat, and secondary pollutants.
Gusseted bags are large bags with smooth ends and edges. They are popular for providing extra space for bulk product storage. Therefore, gusseted bags are suitable for packaging large volumes of dried fruits. These pouches can also be used for packaging smaller volumes.
Pillow Bags (Pillow Packs)
Pillow bags are named for their pillow-like appearance and are commonly used for packaging dried fruits. These bags are the most suitable for packaging dry fruits because they provide large space for storing the fragile fruits.
Sachets
Sachets are small bags that are sealed on three or four sides. They are also used for single-serving portions of dried fruits and can be easily used for direct consumption.
Cardboard Boxes
Cardboard boxes are made of cardboard surfaces with single or double-layered walls. Such boxes are designed to ensure the high safety of the product against physical damage during transportation. Cardboard boxes can protect against physical damage to some extent.
Paper Boxes
Paper boxes are derived from herbal sources and are highly environmentally friendly. These boxes are made using sturdy paper, making them easy to print with any type of label.
Metal Cans
Metal cans are smooth-surfaced containers that are typically used for storing dried fruits. They are highly durable and comply with safety standards for dried fruits. Therefore, most renowned producers of dry fruits use metal cans for packaging their products.
Bottles
Bottles are another type of packaging containers for dried fruits, designed to fully protect the contents from damage. Bottles come in various sizes, shapes, and materials such as plastic, glass, and paper.
Plastic Cups
Plastic and disposable cups are also used for packaging dried fruits. They are easy to use, cost-effective compared to other types of packaging, and make your product look more appealing.
Plastic Containers
Disposable plastic containers are one of the best packaging options available for packaging dry fruits. They are made of plastic and sealed using a tray sealer machine. These containers provide complete protection against physical damage to the products, as well as protection against light, oxygen, moisture, and secondary contamination.
Using these containers allows for packaging with vacuum and gas injection to increase shelf life and maintain the initial quality of the product for a longer period.
Moreover, plastic containers and films enable the printing of logos and comprehensive information directly onto the packaging.
Considerations for Packaging Dried Fruits
Packaging dried fruits is essential not only for aesthetic purposes but also to ensure the preservation of product quality. Here are number of points to consider regarding the packaging of dry fruits:
Moisture Defense: Since dried fruits undergo a process that significantly reduces their moisture content, it is crucial that their packaging prevents reabsorption of moisture from the environment. When dried fruits absorb moisture from the surroundings, their texture, taste, and shelf life are altered.
Protection against UV Rays: Prolonged exposure to light, especially ultraviolet (UV) rays, can deteriorate the quality of premium dried fruits and lead to color fading and a reduction in vital nutrients.
Protection against Oxygen: The presence of oxygen can trigger oxidation in dry fruits, negatively affecting their taste, flavor, and nutritional content. Therefore, choosing packaging materials known for their excellent oxygen barrier properties can provide a significant advantage.
Protection against Pests: Dried fruits can be tempting for pests such as insects and rodents. Therefore, ensuring that the packaging is impermeable to such pests is essential for maintaining product integrity. Additionally, removing oxygen from the package can prevent insect growth within the packaging.
Environmentally Compatible Materials: In today's environmentally conscious world, selecting biodegradable or recyclable packaging materials can make a difference.
Packaging Size: Considering consumer needs, it is wise to offer a variety of packaging sizes. Single-serving packages are suitable for smaller volumes and travel purposes, while larger packages are suitable for home storage.
Safety during Transportation: Transporting products from the manufacturer to the consumer can be long and challenging. Therefore, using firm packaging that can adequately protect against potential damages, such as breakage, during transportation is crucial.
Packaging Materials for Dried Fruits
Different materials can be used for packaging dried fruits, including:
- OPA/PE (Oriented Poly amide and Polyethylene)
- PER/PE-EVOH-PE (Polyester laminated to barriered Polyethylene)
- PET/PP (Polyethylene Terephthalate/Polypropylene)
- Polyethylene (PE) or Polypropylene (PP) packaging can be used in various forms such as containers, pillow pouches, stand-up pouches, etc.
- Packaging dried fruits in Poly Crystalline or Crystal containers can be done according to customer requests. These containers are made of polystyrene, a durable plastic material. Polystyrene is popular in the packaging industry due to its durability and cost-effectiveness. Other advantages of crystal containers include transparency, hardness, and low water absorption. It's worth noting that this packaging material has low polarity, making it a good insulator against temperature and moisture. However, their higher price compared to pouches could be considered a drawback.
Sealing Methods for dry Fruits
Preserving the quality, freshness, and taste of dried fruits is vital for both producers and consumers. Effective sealing methods can significantly increase the shelf life and integrity of dried fruits. For this purpose, three methods are commonly used: negative pressure vacuum sealing, nitrogen-filled vacuum sealing, and sealing with nitrogen gas flushing.
The general process of packaging dried fruits consists of several stages, which are as follows:
Preparation and Quality Inspection
In the first stage, the fruits are thoroughly processed by washing, slicing, and drying. Then, the quality of the dry fruits, including moisture level and detection of any contaminants like metal, etc. is inspected.
Weighing the Dried Fruit
After the preparation and quality assessment stage, the dried fruits are loaded onto the packaging machine. Here, with the help of multi-head weighing packaging machine, the quantity of dried fruits is measured by the operator using the machine.
Nitrogen Flushing
The third stage involves purging the packages of dried fruit with nitrogen flushing before filling. Prior to filling the packages with dried fruits, nitrogen gas is flushed into them to completely remove oxygen from the packaging. In some cases, such as pillow bag packaging, nitrogen gas remains in the package to eliminate the integrity of the dry fruits during transportation.
In packaging by the pillow pack machine, usually, part of the oxygen inside the package is removed by nitrogen pumping, but in packaging inside plastic trays and by tray sealer machines, first, with the vacuum of the air inside the package to a great extent, removed and then nitrogen gas is injected into the package. This method has higher accuracy and yields better results.
