The Spring Festival is coming, and every family is preparing for the reunion dinner. In addition to rich dishes, dried fruits are also indispensable for the New Year. Dried fruit packaging can not only protect dried fruit, but also play a role in shaping the brand. In daily production, the material, specifications and use of dried fruit packaging bags vary according to the type of dried fruit and market demand.
First, dried fruit packaging bag considerations
Preservation: Because dried fruits are dried, they are more susceptible to moisture and oxidation. Therefore, the packaging material needs to have sufficient barrier properties to maintain the dryness and fragrance of the dried fruit. For example, materials with high barrier properties such as aluminum foil or nylon can be selected.
Safety: Packaging materials must be food grade to ensure the safety of the product. At the same time, the packaging should also be able to withstand the pressure and friction during transportation and storage, without any adverse effects on the dried fruit.
Aesthetic: Dried fruit packaging also needs to be considered aesthetic, because they are often used as gifts or holiday giveaways. The packaging design should be attractive and able to highlight the characteristics of dried fruit. At the same time, the text and label on the package should also be clear and easy to read, providing the necessary product information.
Convenience: Packaging should provide a mechanism for easy opening and reclosing so that consumers can easily use and preserve dried fruit. At the same time, the size and shape of the package should also adapt to the shape and size of the dried fruit in order to better protect and display the product.
Environmental protection: With the increasing concern for environmental protection, the choice of recyclable or degradable packaging materials is also a factor to consider. This can not only reduce environmental pollution, but also enhance the company's environmental image.
Second, the common material of dried fruit packaging bags
Vacuum bag: Vacuum bag is a method of drawing out the air in the bag to make the bag close to the surface of the dried fruit. This method can effectively prevent air and moisture from entering the bag and ensure the freshness of the dried fruit. In addition, vacuum packaging can also inhibit the growth of bacteria and mold, and improve the shelf life of dried fruits. However, the cost of vacuum packaging is higher and it is more difficult for some irregular shaped dried fruits.
Nitrogen-filled bags: Similar to vacuum packaging, nitrogen-filled bags draw the air out of the bag before sealing and then fill it with pure nitrogen. This can effectively prevent oxygen from contacting the dried fruit, delay the oxidation process, and maintain the freshness and taste of the dried fruit. This packaging bag is suitable for dried fruits with high preservation requirements, such as pistachios, almonds and so on.
Ordinary packaging bag: Some dried fruits are not overly packaged when they are sold, and only ordinary plastic bags or paper bags are used for simple packaging. This packaging method has a lower cost, but may not provide a good preservation effect, and is suitable for dried fruits with low preservation requirements, such as peanuts, sunflower seeds and so on.
Aluminum foil bag: This bag is made of metal aluminum, has good barrier properties and moisture resistance, can extend the shelf life of dried fruits. Aluminum foil packaging bags generally use high temperature sealing technology to ensure a firm seal and prevent air and moisture from entering. This packaging bag is suitable for high-end dried fruits or gifts.
Paper boxes or paper bags: some dried fruits are packaged in paper boxes or paper bags, the appearance is simple and generous, suitable for gifts. This type of packaging usually does not provide a sealing function, so it needs to be used with the inner bag to maintain the freshness of the dried fruit.
When choosing dried fruit packaging bags, it is necessary to consider the type of dried fruit, preservation requirements, cost and other factors. At the same time, in order to ensure food safety and hygiene, non-toxic and odor-free packaging materials should be selected, and sanitary conditions in the production process should be ensured.
