Now e-commerce platforms and offline fresh supermarkets have applied body-fitting packaging in meat products. Different from the previous frozen meat and ordinary modified atmosphere packaging, the skin packaging not only lengthens the preservation period, but also effectively protects the appearance of the ingredients themselves.
Preservation period of body-fit packaging
For products packaged with skin, the film is completely packed with meat, forming a vacuum-like environment, but its effect of isolating air and bacteria is better than that of vacuum packaging.
At present, the fresh cold chain in the industry mainly has two ways of putting dry ice and nitrogen. Dry ice can last up to two days, and nitrogen can only last up to one week. The skin packaging can ensure that the meat is kept fresh for 21 days at 0-4 ℃.
The preservation advantage is obvious. Advantages of skin packaging compared to other packaging
1. The effect of isolating air and bacteria is better than that of vacuum packaging, moisture-proof, anti-oxidation, and prolong shelf life;
2, packaging to highlight its natural appearance, enhance the desire to buy;
3, the body close to the food, juice can not seep, reduce bacterial reproduction;
4, to prevent fresh meat and seafood products produce frozen spots;
5. It can be shockproof and anti-friction, and will not damage the product due to transportation;
6, no mold production, save packaging volume, save costs;
7, the packaging is easy to tear, easy to use.
Packaging selection is exquisite, better than ordinary packaging
The principle of body packaging is to place the product on a breathable bottom plate (cardboard or plastic sheet), cover it with a heated and softened plastic film, and vacuum through the substrate to make the film tightly wrap the product and seal it with the bottom plate.
(1) At present, there are a variety of food-specific vacuum-coated packaging films, which can be selected according to the packaging products.
Breathable film: high permeability, easy to form, suitable for frozen food;
② oxygen barrier film: high barrier to oxygen, can effectively extend the shelf life of food;
Good formability, can maintain the complete shape of soft food;
Multi-layer co-extruded electronic cross-linked film: good barrier performance, suitable for fresh refrigerated food, mainly used for automatic continuous patch packaging machine.
(2) the bottom plate, due to the food, there are generally two types, one is the flat plate bottom, made of plastic sheet or paper plastic composite material; the second is the tray, made of plastic with a certain shape of the shallow plate.
Although its packaging cost is relatively high, it has high color value and strong functionality, which is especially suitable for new retail terminal channels. Insiders said that in the future in fresh food, the application of body packaging will be more and more. Because differentiated packaging can directly enhance product strength, it is necessary to position high-end high value-added products. On the whole, the body packaging is also a display of the manufacturer's product strength, processing strength, and innovation strength, which can better meet the needs of corporate brand upgrades.
