In the modern food industry, packaging is not just an external protective layer, it plays a vital role in maintaining the freshness of food, extending the shelf life and providing consumer safety. Especially in humid environments, food storage and transportation face many challenges. Moisture-proof technology is one of the keys to solving these problems. This article will explore the moisture-proof technology in food packaging in depth to help food manufacturers and wholesalers choose the right packaging method to ensure the freshness of food.

Basic concepts of moisture-proof technology

Moisture-proof technology refers to the process of preventing moisture from entering food packaging through a series of means to prevent food from getting damp, moldy or deteriorating. In food packaging design, the application of moisture-proof materials and technologies not only improves the sealing of packaging, but also effectively extends the shelf life of food.

Common moisture-proof packaging materials

Aluminum foil packaging

Aluminum foil is one of the most common materials in moisture-proof packaging. It has excellent waterproofness and air-isolating ability, which can effectively prevent food from getting damp. Aluminum foil packaging is often used for foods with heavy moisture, such as dried fruits, coffee and seasonings.

High barrier film

High barrier film (such as PET/AL/PE composite material) can prevent the entry of water vapor, oxygen and light, and is an indispensable material in many food packaging. This film is often used to package foods that are highly sensitive to moisture, such as cereals and candies.

Hygroscopic materials

Hygroscopic materials play an important role in packaging, especially in food packaging, which can effectively absorb excess moisture and maintain a dry environment inside the package. Such materials are often used in combination with other packaging materials to provide additional moisture protection.

Application of moisture-proof technology in food packaging

Moisture-proof technology has different applications in different types of food packaging. Whether it is food retail packaging or wholesale packaging, choosing the right moisture-proof material can effectively prevent food from getting damp and maintain the taste and quality of the food.

Bag food: Many snacks, biscuits, dried fruits, etc. are packaged in composite film bags. This packaging method has both moisture-proof function and good sealing to prevent food from being affected by external environmental moisture.

Boxed food: For boxed food, aluminum foil lining or thickened plastic film is often used as a moisture barrier to prevent external moisture penetration and ensure the freshness and safety of food.
