Invisible Skin Film for Vacuum Packaging
20 October 2025 In the world of food packaging, skin film technology for vacuum packaging represents one of the most innovative and sustainable solutions for preserving and presenting fresh and frozen products. With over fifty years of experience in polyethylene film extrusion, ITP is a leader in the production of skin films with ClearSkinPack®, developed by its in-house R&D lab in a range of films tailored to every need.
What Is Skin Film for Vacuum Packaging?
ClearSkinPack® invisible vacuum skin film is a high-barrier coextruded film that, through a vacuum thermoforming process, adheres perfectly to the food product like a “second skin.” This system ensures optimal protection, preserving freshness without the need for Modified Atmosphere Packaging (MAP), while enhancing the product’s appearance, which can even be displayed vertically on shelves.
Advantages of ITP’s Invisible Skin Film for Vacuum Packaging
- Adhesion without glue: The film is applied without adhesives, simplifying recycling and reducing the use of chemicals.
- Dual sealing action: The residual heat from the top film seals the product, while the tray edges are closed via heat sealing, ensuring package integrity.
- Efficiency and sustainability: Compact packaging reduces material usage and transport costs, contributing to lower CO₂ emissions.
- Strength and versatility: The skin film offers high resistance to punctures and temperature variations, making it ideal for bone-in meats, fish, ready meals, and frozen foods.
Technical Performance
ClearSkinPack® stands out for:
- High transparency and gloss, enhancing shelf appeal.
- EVOH barrier, essential for extending food shelf life.
- Mechanical strength: protects products with sharp or pointed parts, such as bone-in meats or frozen items.
- Microwave suitability (depending on tray bottom), for added convenience.
- Available in various thicknesses from 80 to 150μm.
- Printable up to 10 colors, allowing packaging customization and brand communication.
- Compliance with European food contact standards.
Applications
Skin film for vacuum packaging is used across many food sectors:
- Fresh and processed meats (including bone-in)
- Fish and seafood (crustaceans, shellfish)
- Ready meals and deli products
- Frozen foods and items subject to thermal shock
Solutions for Every Tray Type
ITP has developed ClearSkinPack®, a line of invisible skin films for vacuum packaging designed to adapt to various tray types and food products. The true strength of this range lies in its ability to offer specific solutions based on tray material: whether polypropylene (PP), polyethylene (PE), polystyrene (PS), or PET, there is a film that ensures perfect sealing and optimal protection.
Sealing is one of the most critical aspects of food packaging. ClearSkinPack® films are designed to adhere perfectly to trays without the need for glues or additional adhesives. This reduces chemical use, making the process more sustainable.
- Films for PP, PET, PS, PE
These skin films are ideal for those seeking maximum flexibility: they adapt to trays made of various materials, ensuring secure and durable sealing. Available in different thicknesses (from 80 to 150 microns), they offer tailored solutions depending on the product—be it bone-in meat, fish, ready meals, or frozen foods. - Dedicated Films for PE
For users of polyethylene trays, ITP offers a dedicated version with the same transparency, resistance, and barrier properties. Here too, sealing is optimized to ensure maximum strength and safety.
All films are made from raw materials compliant with European food contact standards. Production is fully verticalized: from resin selection to printing, every phase is controlled to ensure quality and safety.
Sustainability and Innovation
ITP continuously invests in research and development to offer increasingly sustainable solutions. The vertical integration of production—from raw material to finished product—ensures total process control and the highest quality.
The company is certified ISO 9001, ISO 14001, ISCC Plus, and BRC, and has received international recognition such as the WorldStar Award 2025 and Best Packaging 2024.
