The core mission of the nut packaging bag is to combat the four major enemies of nuts: oxygen, light, moisture, and physical impact, in order to minimize the oxidation and spoilage of oils, maintain the crispy texture, fresh flavor, and nutritional value of the nuts. At the same time, it serves as an important channel for brand-consumer communication and value delivery. Through precise technologies (such as nitrogen filling) and meticulous design, it has found the best balance between ultimate preservation, brand building, convenience for consumption, and environmental protection. It is an essential core component of nut products. Choosing the right packaging bag directly determines the market competitiveness and lifecycle of nut products.
Ordinary sealed bags: The most basic packaging form, providing simple sealing functionality, suitable for short-term consumption or bulk products.
Self-tightening zipper bags: Currently the mainstream choice in the market. The built-in zipper offers repeatable sealing capability, facilitating multiple uses; the self-standing bottom enables the bag to be placed upright, enhancing the display effect on shelves and the convenience for consumers.
Bags with exhaust valves: Primarily used for coffee beans, but also applicable in some nuts that need to release trace amounts of natural gases (such as freshly baked nuts) to prevent the bag from bursting. This helps to prevent the bag from expanding.
Vacuum packaging bags: By removing the air inside the bag, creating an environment close to vacuum, it significantly delays oxidation and is one of the most effective methods for maintaining the quality of dried fruits. Commonly used in high-end products.
Nitrogen-filled packaging bags: Before sealing, the bag is evacuated and filled with inert gases such as nitrogen. Nitrogen can displace oxygen, effectively preventing the oxidation and spoilage of fats and oils, and is the industry standard preservation technology.
Aluminum foil bags: Provide excellent barrier properties, completely blocking light, oxygen, and moisture, and effectively maintaining the flavor of the product without loss. Often used for high-end nuts, health supplements, etc., with extremely high preservation requirements.
