What is the difference between vacuum packaging and skin packaging?

In traditional vacuum packaging, film is drawn around the product but does not adhere perfectly — a residual gap remains between film and surface. In vacuum skin packaging (VSP), the top film is heated and draped over the product like a second skin, adhering perfectly even to irregular shapes and eliminating visible liquid.

Which technology gives a longer shelf life: vacuum or skin?

Both technologies remove oxygen, but VSP generally delivers longer shelf life thanks to the perfect film adhesion that eliminates residual micro air pockets. For fresh meat: traditional vacuum offers 21–28 days, while VSP can reach 35–40 days.

Does skin packaging cost more than vacuum?

Yes. Skin film is more expensive: €0.10–0.25 per pack vs €0.03–0.08 for traditional vacuum film. However, VSP reduces returns due to product appearance and allows premium positioning that often justifies the higher cost.

Which EMA machines support vacuum skin packaging?

EMA Pack thermoformers (MTF/STF/LTF series) and tray sealers (STS/DTS series) support vacuum skin packaging as a configuration option.

Comparison guide

Vacuum vs Skin Packaging

Both technologies eliminate oxygen and protect the product, but they do it differently and with very different shelf results. Find out which is right for your product.

Vacuum packaging

Film is drawn around the product and sealed. The film does not adhere perfectly to the surface: a residual gap remains between film and product, especially at the edges. Mature, economical and reliable technology.

Meat shelf life: 21–28 days (vs 5–7 days loose)
Film cost: €0.03–0.08/pack
Suitable for chambers, thermoformers, belt machines
Ideal for whole cuts, cured meats, cheese, fish
May generate drip in liquid products
