Application of sealing film in the food industry

Large Middle Small Source:Leadtra Packaging View:- Date:2025-07-03 13:54:03

Sealing film plays a key role in the field of food packaging, and its excellent sealing performance provides reliable preservation protection for various types of food. In liquid food packaging, aluminum foil composite sealing film is widely used in beverage packaging such as juice and dairy products due to its excellent barrier properties, effectively preventing oxygen and moisture from penetrating, significantly extending product shelf life. For carbonated beverages and other carbonated products, special pressure resistant sealing films can withstand internal pressure to ensure transportation safety.

Solid and powdered foods also benefit from the protection of the sealing film. Moisture resistant aluminum foil sealing film is used for products such as milk powder and coffee powder that are prone to moisture, effectively blocking the intrusion of water vapor and preventing clumping and deterioration. Snack packaging combines nitrogen filling technology with high sealing film to maintain the crispy taste of the product. These sealing films are usually equipped with easy to tear designs, greatly enhancing the convenience of use for consumers.

Instant food and frozen food have higher requirements for sealing films. The microwave food sealing film can withstand high temperatures above 120 ℃, ensuring the safety of the heating process and the integrity of the packaging. The anti freezing and anti cracking sealing film used for frozen food can maintain flexibility even in low temperature environments of -18 ℃, avoiding brittleness and cracking caused by freezing.

With the advancement of technology, functional sealing films continue to emerge. Modified atmosphere packaging uses sealing film with selective breathability to extend the shelf life of fresh food by adjusting the gas ratio inside the packaging. Environmentally friendly biodegradable sealing film conforms to the trend of sustainable development, using environmentally friendly materials such as PLA to reduce environmental pollution.

The humanized design of the sealing film continues to enhance the user experience. Innovative designs such as easy to tear and one click opening allow consumers to conveniently access food. These designs are particularly common in daily food packaging such as yogurt and seasonings, ensuring both sealing performance and convenience of use.

Looking ahead, with the continuous innovation of food packaging technology, sealing film will play a more important role in food safety, preservation technology, and user experience. Intelligence and environmental friendliness will become the main directions for the development of sealing films, providing safer, more convenient, and more sustainable packaging solutions for the food industry.
