Vacuum skin packaging (VSP) is a method in which the product is placed on a base material and tightly sealed with a transparent film that conforms closely to its shape, making the package appear almost invisible. The product can be packaged not only in clear plastic trays, but also on various carriers such as rigid base films, cardboard, and paper trays. This packaging process helps extend shelf life, minimize product movement during transportation, reduce wastage, and create an aesthetically appealing presentation.
In this article, you will learn what the process of vacuum skin packaging is, its applications, how it measures up against other packaging processes, and how you can go about selecting the most appropriate equipment for your needs. You will also learn how vacuum skin packaging by Hualian Machinery helps businesses of all sizes, including food processors and industrial companies.
Vacuum skin packaging is the packaging technique where a heated, flexible skin film is shrunk around a product through the force of vacuum pressure before sealing to a rigid tray or backing material such as paperboard.
This starts by positioning the product on a rigid tray or backing material. This step also involves ensuring the positioning of the product is correct. Correct positioning of the product will help ensure even shrinking of the film and give a more professionally packaged product.
This involves heating the skin film to make it soft and flexible. The temperature used for heating should be carefully monitored. Overheating of the skin film may lead to excessive thinning and weakening of the film, while insufficient heating may prevent proper shrinking of the film around the product. This is one of the reasons why professional vacuum skin packaging machinery gives better results than manual packaging techniques.
When the product and heated film are placed in the sealing chamber, a vacuum pump extracts the air from the package. As the air pressure lowers, the atmospheric pressure compresses the softened film down onto the product until it is firmly wrapped around it. This process allows for the removal of the oxygen that surrounds the product and makes it stable inside the package.
After reaching the desired vacuum level, the machine seals the film to the tray or other backing. It is important to have a good seal to ensure the integrity of the package during storage, transport, and distribution.
Before the packaging is labeled, boxed, or palletized, an inspection is done on the finished product. This will help to keep a consistent quality level and reduce returns.
Skin film needs to wrap items of various shapes and sizes without losing its ability to resist punctures and provide outstanding oxygen barrier properties. Very good cuts of meat with bones exposed may need more durable films than cheese or ready meals.
The tray forms the base of the pack. It provides support for the product, protects the item from damage during transport, and gives an appealing look on the shelves. The trays can be made of PET (high transparency), PP (high heat resistance), or paperboard for sustainable projects.
Vacuum pump removes air from the packaging cell. Good vacuum system guarantees the same vacuum level each time the machine is working. This will have direct effect on the shelf-life of the product, package look, and sealing quality.
The sealing system seals the film to the tray with the help of temperature, pressure, and time. New packaging machines are provided with programmable controllers that ensure a constant level of sealing parameters in the process of continuous packaging.
Due to its snug fit with the product, the vacuum skin packaging allows natural textures, colors, and forms of the item to be presented clearly without any wrinkles and bubbles of air. The outcome is an elegant and upscale look of the product, which may be considered a ‘second skin’ of the item and can improve the presentation in refrigerated displays.
Fresh meat and fish produce juices when stored. The vacuum skin packaging helps to avoid this problem as the film adheres to the surface of the product very closely. Although a purge still happens in this case, the movement of liquids in the package is reduced considerably.
The vacuum skin packaging improves the safety of the packaging system. The tight seal protects the product from external contamination when it is transported and stored. Also, because the product is firmly sealed in the tray, there is less risk of damaging the package.
Unprocessed beef, lamb, pork, and exotic meat continue to be the greatest consumers of vacuum skin packaging technology. This category enjoys an extended life on the refrigeration shelf, minimized movement of the products, and improved protection during the transportation process.
Vacuum skin packaging helps to stabilize fish fillets, shrimp, shellfish, and other seafood that are very fragile and susceptible to spoilage. In addition, the thin film minimizes the movement of the products, thus keeping the products in good shape after transport to retail stores.
Chicken, duck, turkey, and other processed poultry products enjoy the benefits of vacuum skin packaging. This provides protection during transport and improved presentation at retail stores.
Deluxe cheeses must be packed in a way that preserves taste but does not compromise on appearance. Vacuum skin packing prevents air contact and provides good visibility for consumers.
Consumers have an increasing preference for ready-to-eat and ready-to-cook meals. Vacuum skin packing is applied to improve the display of meals and their protection during transportation. This is due to the fact that the food items are firmly placed in the tray and therefore reach the consumer more attractive than upon packaging.
Numerous manufacturers of frozen foods have started using vacuum skin packaging to avoid the phenomenon of freezer burn and improve package integrity. The thin film reduces air entrapping.
The use of vacuum skin packing may also be beneficial for medical devices, surgical instruments, precision tools, electronic components and industrial hardware. This kind of packaging prevents dust, moisture and movements of items while allowing consumers to see the content without opening the package.
