Food preservation film is a functional film product specifically designed for food storage. Endowed with excellent sealing, oxygen-barrier, and moisture-retention properties, it has become an indispensable food preservation tool in home kitchens, the catering industry, and the food retail sector. Its core function is to delay the oxidative deterioration of food and reduce moisture loss, thereby extending the freshness period of food and minimizing waste.
Moisture Retention & Freshness Preservation: It adheres closely to the surface of food, effectively reducing moisture evaporation from ingredients such as fruits, vegetables, and cooked food. This prevents ingredients from becoming shriveled and losing their texture due to moisture loss (e.g., cut watermelons, lettuce salads).
Oxygen Barrier & Oxidation Prevention: By isolating oxygen in the air, it slows down the oxidation reaction of ingredients, delaying the spoilage of meat and seafood, as well as the “browning” of cut fruits (e.g., apples, pears) caused by oxidation.
Odor Isolation & Hygienic Protection: When stored in the refrigerator, it can separate the odors of different foods (e.g., the pungent smell of onions and garlic does not interfere with the aroma of pastries and fruits). Meanwhile, it prevents food from directly contacting the inner walls of the refrigerator, reducing the risk of cross-contamination by bacteria.
Convenience & Ease of Use: Most products adopt a “roll + cutter” design, allowing flexible cutting of lengths according to the size of the food. The thin, lightweight, and transparent material also makes it easy to check the condition of the wrapped food—there is no need to unwrap it to confirm the type and freshness of the ingredients.
