How to extend the shelf life of food is a question that many entrepreneurs in the food industry have been considering. The common methods are: Adding preservatives, vacuum packaging, modified atmosphere packaging, and meat radiation preservation technology. Choosing the right and appropriate packaging form is very important to the sales of the product, so have you chosen the right packaging?

We have a customer who runs a company that makes instant fast food. Their original way of selling fast food was to manually fill food in prefabricated thermoformed polypropylene trays and buckle PP covers on the trays. In this way, the frozen shelf life is only five days, and the scope of distribution is limited, usually direct sales.

Then they bought a tray sealing machine to extend the shelf life of the product. Later, they purchased the first semi automatic tray sealer with modified atmosphere packaging from us, by using modified atmosphere preservation technology, they expand the scope of food sales. Now they are using a new type of vacuum skin packaging. Their company director has long favored vacuum skin packaging (VSP). He believes this packaging will attractive when displayed in a clean and tidy store, which is why this technology is so popular in Europe.

After that, this instant fast food company replaced modified atmosphere packaging (MAP) with vacuum skin packaging (VSP). This kind of packaging has extended the shelf life of their frozen food from the initial 5 days to 30 days and expanded their product sales to further places. This company takes full use of the unique product sales and display opportunities offered by vacuum skin packaging.

Like the concept of vacuum skin packaging, the transparent skin film conforms to the shape of the product and covers the surface of the product and the tray by
vacuum suction. As a pioneer in China, Utien Pack already has relatively mature technical advantages in this field. This kind of packaging can not only improve the appearance of the product, but also prolong the shelf life of the product to the greatest extent. Vacuum skin packaging is suitable for products with hard or relatively stable materials, such as steak, sausage, cheese or frozen food, also applicable to products with soft texture, such as fish, meat sauce or aspic, and thin fish fillets. For the products in the freezer, it can also prevent freezing and burning.

In addition to the above features, vacuum skin packaging has the following advantages:
1.Strong three-dimensional sense, clearly visible products, effectively improve the sense of product value and grade;
2.The product is completely fixed between the skin film and the plastic tray, which is dust-proof, shock-proof and moisture-proof;
3.Compared with traditional protective packaging, it can reduce packaging volume, storage and transportation costs;
4.Display packaging with high grade and super transparent visual, which greatly enhances product market competitiveness.

Sometimes we change the original packaging form and choosing the really suitable packaging form can extend the shelf life of the food and bring more benefits for yourself !
