The importance of VSP food packaging vacuum packaging film for the preservation of seafood cold fresh food
V SP Skin importance of food vacuum packaging film of food seafood cold meat body-preservation:
a, VSP body-vacuum food packaging films for the food cold meat seafood skin packaging the shelf life of
the use of skin packaging product packaging uses The film is completely attached to the meat, forming a vacuum-like environment, but its effect of isolating air and bacteria is better than vacuum packaging.
At present, the fresh cold chain is mainly dry ice and nitrogen in the industry. Dry ice can last two days and nitrogen can last one week. Body-packing ensures that the meat is kept fresh at 0 ° C for 21 days.
Second, VSP food packaging vacuum packaging film has obvious advantages
in keeping fresh seafood and cold meat food: Compared with other packaging, skin packaging has these advantages:
1. The separation of air and bacteria is better than vacuum packaging, moisture-proof, anti-oxidation, prolonged Shelf life;
2. The package highlights its natural appearance and enhances the desire to purchase;
3. When the plasma membrane is close to the food, the juice cannot seep out and the bacteria reproduction will be reduced.
4. Prevent frost spots on fresh meat and seafood products;
5. Can prevent shock and friction, and do not damage the product due to transportation;
6. Do not need die cutting to save packaging volume and cost.
7. The packaging is easy to tear and easy to use.

Third, the cost of packaging materials is three times that of ordinary packaging. The principle of
V SP food packaging vacuum packaging film is to place the product on a breathable bottom plate (cardboard or plastic plate), cover it with a heat-softened plastic film, and vacuum the substrate to tightly wrap the product and seal it with the bottom.
At present, there are various special vacuum-fitting food packaging films, which can be selected according to the packaging product.
(1) Breathable film: high permeability, easy to shape, suitable for frozen food;
(2) oxygen barrier film: high oxygen barrier can effectively extend the shelf life of food;
(3) good moldability, can maintain the complete shape of soft food.
(4) Multi-layer co-extruded electronic cross-linking film: good barrier performance, mainly suitable for seafood cold fresh meat food, mainly used in automatic continuous close-pack packaging machine.
There are two kinds of food on the bottom plate, one is a flat bottom bracket made of plastic plate or paper-plastic composite material; the other is a tray made of a certain shape of shallow plastic plate.
Although the packaging effect and performance are very good, compared with ordinary packaging, high cost has become an obstacle to widespread application, and its cost is 3-4 times that of the former.
Although its packaging cost is high, it has high decoration value and strong functionality, which is especially suitable for new retail terminal channels. Some industry insiders said that in the future of seafood cold and fresh food, the application of personal packaging will be more and more.
Because differentiated packaging can directly increase the strength of the product, it is necessary to position high-end value-added products. In short, skin-packaging is also a demonstration of manufacturers' product strength, processing strength and innovation strength, which can meet the needs of corporate brand upgrades.
The vacuum skin packaging (vskin packaging) is to place the packaging product on a special plastic sheet or film, so that the body-covering film covering the product is tightly combined with the surface of the product under the action of heating and vacuum suction, and sealed with the bottom film. Not only are the body-packed packaging products well-protected, they also show their natural form and appearance.
The application of VSP in food packaging has many advantages that are difficult to replace.
1. good vacuum and close protection, longer shelf life;
2. No vacuum tunneling and fluid accumulation;
3 show the effect of better packaging, to attract the eye;
4. Reduction of freezer burn of frozen food;
5 can be used for packaging soft Content;
6. Vertical display, reducing display space and convenient distribution.
However, the existing vacuum skin-packaging packaging film has poor thermal insulation effect, insufficient overall structural strength, and poor anti-counterfeiting performance. As a result, the vacuum skin-packing packaging film has different product levels on the market and cannot function. Actively meet the needs of the vacuum packaging industry.
