How does vacuum skin packaging machine work
There are several types of vacuum skin packaging machine, semi-automatic or fully automatic machines, which might be different in the exact working process, but as a same packaging technology, all the packaging machines share similar general processes.The marin part of whole vacuum skin packaging process is completed in the vacuum sealing chamber, where vacuum skin packaging machine uses heat (to soften the skin pack film) and vacuum to pull the transparent and flexible top skin film to seal and adhere the product tightly to the trays (pre-made or thermoformed) or cardboards. All atmosphere is removed from inside the package and the product is held in place within this “second skin”.
- The food product is placed in a vacuum skin packaging tray, or on a cardboard
- The skin pack tray and product is placed in the mold of the vacuum skin packaging machine
- The mold is placed into vacuum sealing chamber, or automatically slided into vacuum sealing chamber
- In vacuum sealing chamber, the air in package is completely evacuated, sealing film heated and drawn to adhere to skin pack tray
- Automatic cut the sealing machine, or manually cut

What are the benefits of Vacuum Skin Packaging
Reasons VSP vacuum skin packaging can be a great enhancement to your business
VSP vacuum skin packaging technology has been evolving since it was invented and applied to food packaging. With new skin pack technologies, vacuum skin packaging machines, and modern materials, VSP is becoming one of the most common packaging options for various food products. The advantages and benefits of vacuum skin packaging lie in the below points:
1. Shelf-life extension.
Vacuum skin packaging removes almost all the air from the package, and keeps the food from exposure to oxygen, thereby inhibiting microbial growth and preventing oxidation, preventing food spoilage, prolonging shelf-life, and maintaining the taste, color, and nutritional value of packaged products. The shelf life of the VSP package is nearly double that of a traditional MAP package, and about four times longer than a stretch-wrapped product.
Extended shelf-life of food products helps to reduce food waste and also helps to prevent food safety issues by protecting against food spoilage, leakage, and contamination.
2. Minimize the use of preservatives
Combine with freezer storage, vacuum skin packaging can prolong food’s shelf life to an expected period without the use of preservatives. This feature is super attractive to end-consumers who are pursuing healthy and natural food styles.
3. Vacuum skin packaging help to prevent freezer burns
Food products in vacuum skin packaging are often stored in freezer environment where the temperature is lower than -18°C. Without appropriate packaging, food products will lose moisture and get freezer burn. But with vacuum skin packaging, the air in the package is totally reduced, and with the help of high-barrier skin pack materials, the moisture is well kept in the package so that freezer burn is prevented.
4. Vacuum skin packaging prevents liquid migration
We all know the purge of liquids in a package helps the growth of spoilage bacteria and reduces the shelf-life of food products, so we always try to prevent purge and liquid migration. So far, there’s no other packaging method doing it better than vacuum skin packaging, because the sealing film combines together with the food and plastic tray, so the liquid inside is locked and never flows around the package.
This great feature allows vacuum skin packaging to pack food products that contain soups and sauces, such as ready meals, and also meat and fish products that contain blood and juices.
5. Vacuum skin packaging can be a powerful brand-building tool
The packages processed by vacuum skin packaging machines have a great 3D appearance and see-through features because of the transparent flexible sealing film. There is usually no printing on the sealing film, but a pre-printed label with a brand name can be applied to vacuum skin packages.
Because of these features, food products in vacuum skin packaging is one of the most visually attractive section for end-consumers in supermarkets, grocery stores and food shops.
With the help of cold chain transportation, it’s becoming easier for food products to be sold to natural wide area or even worldwide countries. For example, Musang King durian is so welcomed in China market, but its origin is in Malaysia. Now more and more durian exporters in Malaysia is using vacuum skin packaging technology and cold chain shipping to export Musang King durian to China, with their own label and brand name.
In the ready meals market, end-consumers love the conveniences brought by vacuum skin packaging, because it significantly reduces the preparation time to cook. With the use of microwavable material, ready meals in vacuum skin packaging could be directly put in the microwave to cook after they are taken out of freezers.
6. Vacuum skin packaging makes food storage and presentation more convenient
The bottom rigid skin pack tray provides dependable support and protection to food products inside vacuum skin packaging, during the process of transportation, storage, and display on the shelf, make sure end-consumers receive the product in its original condition without any damage to its appearance, flavor, and color.
Supportive skin pack trays or cardboard allow the vertical display of the packages or hang on the hooks, providing more options when they are showcased to customers.

What’s the shelf life of food products in vacuum skin packaging
When it comes to this topic, we need to understand that vacuum skin packaging is actually a special type of vacuum packaging, they share the same feature: Vacuum, air is evacuated from the packages. The aerobic bacteria are inhibited in the vacuum environment, but anaerobic bacterias are still there and ready to grow any time. And for most food products in vacuum skin packaging, you want to keep them fresh so high-temperature sterilization is not an option.
So the shelf life of food products in vacuum skin packaging is very much dependent on the storage and display temperature.
Just as in regular vacuum packaging, if kept in a freezer, the shelf life of food products in vacuum skin packaging can be prolonged to 12-24 months. Unfortunately, in most cases, we would like to display the foods on the shelf so that consumers can buy them fast. In this case, the environmental temperature would be around 3 ℃, and the shelf life of foods will be about 21-30 days.

Vacuum skin packaging materials
There are several types of vacuum skin packaging that use different material combinations: Pre-made rigid trays and skin pack film; Thermoforming film for rigid tray forming and skin pack film; Paperboard and skin pack film. Vacuum skin packaging is specifically distinguished by the use of thin, transparent plastic film, also known as skin pack film, over skin pack trays composed of strong, durable, leak-proof materials (usually PP, CPET). Skin pack film, largely composed of polyethylene or polyvinyl chloride (PVC), adheres differently to varying substrate materials, so it is important to understand the physical properties of the different tray materials in order to choose the best option for your product. Please contact us for skin pack materials.
- Skin Pack Film: Skin pack films should be transparent, soft, durable, and flexible enough to package products of various shapes and sizes
- CPET Skin Pack Trays: Crystalline polyethylene terephthalate (CPET) trays are durable, heat-resistant, and microwave-safe, making them ideal for ready-to-eat VSP packaging.
- PP Skin Pack Trays: Polypropylene (PP) skin trays are more flexible than CPET trays and are usually used for packaging fresh and pre-cooked foods.
- Paper cardboard: Laminated paperboard is increasing in popularity with VSP applications as it allows for better merchandising and presentation. Also, it reduces the amount of plastic used in the process. It is especially popular for cheeses, fish, and other meats.
