Braised duck neck and marinated foods are common cooked foods in our daily lives. Today's question is: can aluminum foil sealing film seal cooked foods?

The answer is yes.

In the field of cooked food preservation, aluminum foil sealing film is increasingly becoming a "secret weapon" for many brands. Through its unique structural design, aluminum foil sealing film provides triple protection for food:

1. Oxygen Barrier: The Key to Delaying Spoilage

The aluminum foil layer serves as the core barrier, effectively blocking oxygen penetration. Experimental data show that its oxygen transmission rate is far lower than that of ordinary plastic films, significantly delaying fat oxidation and microbial growth in foods such as braised duck neck, thus preventing rancidity or spoilage.

2. Moisture Control: Preserving Texture and Color

The polyethylene layer in the composite structure prevents moisture loss, avoiding dryness and toughness in braised duck neck during storage. At the same time, it blocks external humidity from entering, preventing condensation inside the packaging and maintaining the product’s tender and elastic texture.

3. Aroma Locking: Retaining the Original Braised Flavor

The dense structure of aluminum foil locks in the braised flavor, preventing the escape of aromatic molecules. Consumers can still smell the rich braised aroma upon opening, avoiding quality degradation due to odor mixing.

Application Advantages

Wide Compatibility: It can seal common cooked food containers such as plastic boxes and paper bowls, achieving strong adhesion through heat-sealing technology.

Safety Compliance: Food-grade aluminum foil complies with national standards and does not react with food.

Operational Convenience: Restaurants can use simple sealing machines for quick processing, improving meal preparation efficiency.

Points to Note

Avoid use in strongly acidic or prolonged high-temperature heating scenarios.

Ensure the sealing area is clean and free of oil stains to guarantee sealing effectiveness.

With its numerous advantages, aluminum foil sealing film ensures that every portion of braised duck neck maintains its high quality from production to consumption, making it a reliable choice for modern cooked food preservation.
