Both technologies protect the product and extend its shelf life, but they differ significantly in how the film conforms to the food, the visual result, material requirements and the product’s final market positioning.<\/p>\n\n
Therefore, the question should not simply be which technology is better, but rather: Which packaging system and film structure best meet the needs of the product?<\/p>\n\n In thermoforming<\/a>, the packaging is manufactured directly on the packaging line from a roll of bottom web film.<\/p>\n\n The material is heated and formed to create the cavity into which the product is subsequently placed. The air is then evacuated, and the top web is sealed. <\/p>\n\n In a vacuum thermoforming system, the aim is to reduce the oxygen present around the product before sealing. The top and bottom films form a protective barrier around the food, but the material does not necessarily adhere completely to its surface. <\/p>\n\n This makes conventional thermoforming a particularly versatile solution for manufacturers that require automation, high productivity and a variety of packaging formats.<\/p>\n\n The main benefits of thermoformed packaging<\/a> include:<\/p>\n\n Es una tecnolog\u00eda especialmente consolidada para productos destinados tanto a distribuci\u00f3n como a retail.<\/p>\n\n However, the film does not necessarily follow the contours of the product. Depending on the product’s geometry and characteristics, space may remain between the food and the top film. <\/p>\n\n This may be perfectly suitable from a functional perspective, but it does not always deliver the most attractive presentation when the product needs to stand out visually on the shelf.<\/p>\n\n Vacuum Skin Packaging<\/a> (VSP) uses a top film specifically designed to conform to the product.<\/p>\n\n During the process, the film is heated and moulded around the surface of the food, creating a “second skin” effect. The result is packaging in which the product is securely held in place and clearly visible. <\/p>\n\n This feature significantly changes how the packaging is perceived.<\/p>\n\n Rather than leaving a clearly visible gap between the product and the film, the material follows the product’s contours, even when the food has an irregular shape or varying heights.<\/p>\n\n For this reason, skin packaging has become particularly well established in applications where packaging must not only protect the food but also showcase it and differentiate it at the point of sale.<\/p>\n\n The main benefits of vacuum skin packaging include:<\/p>\n\n The trade-off is that the system requires films specifically designed for skin applications, appropriate processing parameters and compatible equipment.<\/p>\n\n Vacuum thermoforming may be the most suitable option when the priority is to optimise production, costs and product preservation, without requiring the film to conform completely to the product’s surface.<\/p>\n\n It can be particularly beneficial for:<\/p>\n\n Meat products, cheeses and fish sold in large cuts or portions can benefit from the flexibility of the formats available through thermoforming.<\/p>\n\n When packaging is primarily designed to protect the product during storage, transport and distribution, thermoforming can provide an attractive balance between performance and cost.<\/p>\n\n La automatizaci\u00f3n y velocidad de las l\u00edneas de termoformado hacen que esta tecnolog\u00eda sea especialmente adecuada para grandes vol\u00famenes de producci\u00f3n.<\/p>\n\n Not every product needs packaging designed to stand out visually on the shelf. When price, functionality and efficiency carry greater weight, conventional thermoforming may be sufficient. <\/p>\n\n Vacuum Skin Packaging (VSP) becomes particularly relevant when packaging is an integral part of the product’s value proposition.<\/p>\n\n The product remains fully visible and securely held in place, allowing key characteristics such as the cut, colour and texture to be showcased.<\/p>\n\n The clean presentation and the film’s ability to conform to the product can be particularly valuable for products that need to convey freshness and quality.<\/p>\n\n When the food has varying heights, shapes or surfaces<\/a>, skin packaging’s ability to conform to the product can offer a clear advantage.<\/p>\n\n VSP can be used to package prepared foods and products containing different components, particularly when visibility of the contents is important.<\/p>\n\n When packaging needs to support a higher-value market positioning, the presentation offered by skin packaging can become a key differentiating factor.<\/p>\n\n La selecci\u00f3n del film tambi\u00e9n est\u00e1 cada vez m\u00e1s condicionada por los objetivos de sostenibilidad y reciclabilidad.<\/p>\n\n The development of mono-material structures<\/a> is gaining momentum, particularly in applications where the aim is to facilitate packaging management at the end of its life cycle.<\/p>\n\n However, reducing the number of materials or moving towards mono-material structures requires balancing these objectives with the performance the application demands.<\/p>\n\n A film must continue to provide:<\/p>\n\n Therefore, packaging sustainability should not be assessed solely by the number of layers. The overall performance of the packaging and its end-of-life destination must also be taken into account.<\/p>\n\n For food manufacturers, choosing a film should involve more than comparing prices per kilogram. It is essential to determine the specific structure, barrier properties, thickness, mechanical properties and sealing characteristics the application requires. <\/p>\n\n The right question is: which material delivers the right combination of preservation, productivity, safety, presentation and cost for this particular product?<\/p>\n\n At Ttpack, we provide film solutions for a range of food packaging<\/a> and pharmaceutical applications. We assess the requirements of each project to help select a structure that is compatible with the product, the machinery and the objectives for preservation and commercialisation. <\/p>\n\n Explore our packaging solutions or contact us<\/a> for further information.<\/p>\n\n![\"vacuum](\"https:\/\/ttpack.es\/wp-content\/uploads\/2026\/10\/termoformado-vacio-vs-skin.jpg\")
