Packaging is essential for preserving the freshness and quality of food. One of the most innovative solutions in use today is the skin pack, a technique that is gaining increasing popularity. But what exactly is a skin pack, and why is it so commonly used in the food industry?

What is a Skin Pack and How Does It Work?

Skin pack is a packaging technique that wraps food in a transparent film, creating a "shell" that adheres perfectly to the product's surface. Thanks to a thermoforming and vacuum process, the film reduces exposure to air, keeping food fresh longer. This packaging not only protects the food, but also preserves its appearance, remaining visible and inviting.

The process begins with placing the food in a tray, over which a film is applied. Once heated, the film adheres perfectly to the product. The air is then extracted, creating a vacuum effect that slows spoilage. Finally, the film is sealed to ensure airtight packaging.

Why Are They So Popular?

Skin packs are becoming very popular thanks to several advantages. First, they keep food fresh longer, reducing the risk of spoilage by reducing air retention. This type of packaging also preserves the appearance of the food, which remains visible and well-presented. Furthermore, they protect the product from external contamination, improving food safety. These advantages make them particularly suitable for fresh and perishable foods, such as meat, fish, cheese, and ready meals.

What Are The Advantages?

Skin packs not only prolong the freshness and appearance of food, but are also practical. Thanks to the transparency of the film, consumers can see the product without having to open the package, making it easier to choose and reducing food waste. Furthermore, the hermetic protection ensures that food remains safe and fresh until consumption.

With the growing focus on sustainability, many companies are developing skin packs with recyclable or biodegradable materials. This makes the technology even more attractive, as it combines convenience with reduced environmental impact.
