Description

Novel active packaging material

Technical Field

The invention relates to the field of active packaging, in particular to a novel active packaging material.

Background

Active packaging refers to packaging for products with life. The packaging features that the life of the product is maintained, rather than the color, fragrance and taste of the product is simply protected, and once the life is lost and the breath is stopped, the life product loses value or devalues. Common active packages are: packaging of animals and fresh flowers, such as packaging of live fish, young animals (chicken, duck, etc.), young vegetables, young fruits (trees), etc., which can be called "life-keeping package" or "keep-alive package" for short. The packaging material used in active packaging is referred to as the active packaging material. A related art method used in active packaging is called active packaging technology.

The active package has scavenging and releasing functions. The cleaning is to remove oxygen, ethylene, moisture and putrefactive peculiar smell, and the packaging system comprises a packaging bag, a label, a sealing opening and a polymer directly added with a flexible packaging material, thereby realizing the cleaning function. For example, deoxidizers can inhibit the growth of aerobic microorganisms, lipid oxidation, discoloration, flavor loss, and the loss of nutrients. Release refers to release of antimicrobial agents (e.g., silver salts, alcohols, sulfur dioxide, bacteriocins) and release of antioxidants (BHA, BHT). The active packaging technology relates to an interaction mechanism between food, packaging materials and internal gas and a corresponding control technology thereof. Typical techniques are deoxidizer technology, antimicrobial agent technology, and control technology for bad smell, moisture, and carbon dioxide.

When live fish is packaged and transported, the most common transportation method is an oxygenation sealing transportation method, at present, the fish is placed in a packaging bag body filled with water, a sealing machine is used for sealing the opening of the packaging bag body, then oxygen in an oxygen bottle is transported into the bag, and air accumulated in the bag is extruded out, so that the fish can be directly lifted away. However, the method also needs to fill oxygen into the bag after the fish is packaged, so that the packaging time is prolonged, the risk of explosion of the packaging bag body is easily caused due to excessive oxygenation, the existing packaging bag does not have a placating effect on the fish in the packaging bag, the fish can be irritated due to the fact that the activity space of the packaging bag is too small, the survival rate of the fish is reduced, and the long-time transportation of the fish is not facilitated.
