Vacuum packaging bag: Vacuum packaging bag is a method of drawing out the air in the packaging bag to make the packaging bag close to the surface of the dried fruit. This method can effectively prevent air and moisture from entering the packaging bag and ensure the freshness of the dried fruit. In addition, vacuum packaging can inhibit the growth of bacteria and mold and increase 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 packaging bags: Similar to vacuum packaging, nitrogen-filled packaging bags will extract the air from the bag before sealing, and then fill it with pure nitrogen. This can effectively prevent oxygen from contacting the dried fruits, delay the oxidation process, and maintain the freshness and taste of the dried fruits. This kind of packaging bag is suitable for dried fruits with high preservation requirements, such as pistachios, almonds, etc.
Ordinary packaging bags: Some dried fruits are not over-packaged when sold, and are simply packaged in ordinary plastic bags or paper bags. This packaging method has a lower cost, but may not provide a good preservation effect. It is suitable for dried fruits that do not have high preservation requirements, such as peanuts, sunflower seeds, etc.
Aluminum foil packaging bag: This kind of bag is made of metallic aluminum, which has good barrier properties and moisture resistance, which 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 kind of packaging bag is suitable for high-end dried fruits or gift packaging.
Paper boxes or paper bags: Some dried fruits are packaged in paper boxes or paper bags, which have a simple and elegant appearance and are suitable for gift giving. This type of packaging usually does not provide a sealing function, so it needs to be used with an inner bag to maintain the freshness of the dried fruit.
When choosing dried fruit packaging bags, you need to consider factors such as the type of dried fruit, preservation requirements, and cost. At the same time, to ensure food safety and hygiene, non-toxic and odor-free packaging materials should be selected, and hygienic conditions during the production process should be ensured.
