Specialty Films: How Aerolam's High-Barrier and Metallized CPP Films Are Redefining Flexible Packaging Standards
Is your flexible packaging film really doing enough?
Standard packaging films protect products from basic physical damage. Specialty films go much further β they control exactly how much oxygen reaches your product, how much moisture passes through, how strong the seal holds under pressure, and whether your packaging can even be recycled at end of life.
Specialty films are engineered for applications where conventional materials simply cannot deliver the required performance. In India’s food, pharmaceutical, and personal care sectors β where product safety, shelf life, and sustainability are under increasing scrutiny β specialty films have moved from a premium consideration to a baseline requirement.
Aerolam’s specialty CPP film range β metallized, high-barrier, retort-grade, and medical-grade β is designed specifically to meet these exacting standards. Backed by large R&D investments, European manufacturing technology, and FDA-approved raw materials, Aerolam specialty films are the choice of brands that cannot afford to compromise on packaging performance.
What Are Specialty Films β And How Are They Different?
Specialty films are high-performance polymer films engineered with specific functional properties that go far beyond standard commodity films. They are designed with precision-controlled formulations, advanced coatings, or innovative multilayer structures to achieve defined performance targets.
In the CPP category specifically, specialty films include:
- Metallized CPP films β with aluminium metallization for enhanced barrier and premium shelf appeal
- High-barrier CPP films β achieving OTR and WVTR values below 0.1, rivalling aluminium foil
- Retort-grade CPP films β withstanding sterilization temperatures of 121Β°C
- Medical-grade CPP films β designed for steam sterilization and sterile barrier applications
- Heat-sealable high-barrier films β combining barrier and seal in a single functional layer
The difference between a standard film and a specialty film is not just performance β it’s precision. Every parameter is controlled for a specific purpose, in a specific application, under specific conditions.
Aerolam has created innovative metallized barrier films with enhanced Oxygen and Water Vapour barrier properties through large investments in R&D and state-of-the-art production technologies.
Aerolam's Specialty CPP Film Range
1. Metallized CPP Films β Where Barrier Meets Brilliance
Metallized CPP films combine a thin aluminium coating with CPP’s inherent heat-seal strength and flexibility. The result is a film that delivers dramatically improved oxygen and moisture barrier properties β while maintaining the premium metallic finish that elevates shelf presence for snacks, confectionery, and premium food brands.
Aerolam offers three distinct metallized grades:
- MT02 (KKR High Puncture Metallized CPP) β Superior metal bond with exceptional puncture resistance. Available in 20 ΞΌm and 30 ΞΌm. Ideal for snack food, confectionery, and premium food packaging that demands both barrier and durability.
- MT02HB (High Barrier High Puncture Metallized CPP) β Combines high barrier performance with high puncture resistance in a 25 ΞΌm film. The right choice when standard metallized films cannot meet the shelf life requirements of oxygen-sensitive products.
- CPE MT03HB (High Barrier Metallized CPP Heat Sealable) β Ultra-high barrier with integrated heat-seal capability. Available in 20 ΞΌm and 30 ΞΌm. Simplifies laminate structures by combining barrier and seal in one layer.
2. Ultra-High Barrier Films β OTR and WVTR Below 0.1
The CPE MT00HB is Aerolam’s most advanced barrier film. With OTR < 0.1 and WVTR < 0.1, it achieves barrier performance previously only possible with aluminium foil laminates β but in a flexible, metallized CPP structure that is far more sustainable.
This is not incremental improvement. This is a fundamental shift in what CPP-based specialty films can achieve. Available in 20 ΞΌm and 25 ΞΌm, CPE MT00HB enables packaging designers to build monomaterial structures that meet the most demanding barrier specifications β without foil, without PET, and without multi-polymer constructions that cannot be recycled.
OTR < 0.1 | WVTR < 0.1 β Aerolam’s CPE MT00HB delivers barrier performance that directly competes with aluminium foil, in a recyclable monomaterial CPP structure.
3. Retort-Grade Specialty Films β Built for Heat
Two Aerolam grades serve the demanding retort packaging segment:
- RP02 (Easy Peel PP Retort 121Β°C) β 70 ΞΌm, 63.35 GSM. Engineered for retort pouches that require a clean, easy-peel opening after sterilization. Maintains seal integrity and packaging structure through the full 121Β°C retort cycle.
- RT08 (High Impact Retort CPP) β Available at 60, 70, and 80 ΞΌm. Designed for aggressive retort processing of heavier, denser food products including meat, fish, and thick sauces. High impact resistance prevents pouch failure under the combination of thermal and mechanical stress in retort processing.
4. Medical-Grade Specialty Films β Zero Compromise
For medical device and healthcare packaging, Aerolam’s MD01 sets the standard. This CPP film is specifically designed for steam sterilization pouches β maintaining its barrier integrity, structural strength, and peel performance through autoclave sterilization cycles.
Medical packaging cannot afford variability. MD01 is manufactured in a clean room, air-controlled environment, from FDA-approved resins, and available in three thicknesses (30 ΞΌm, 38 ΞΌm, 40 ΞΌm) to match the specific pouch specifications of different medical device categories.

Why Specialty Films Are Now Essential, Not Optional
India’s Shelf Life Expectations Are Rising
Modern retail and e-commerce distribution chains in India mean products spend longer in transit, warehouses, and on shelves than ever before. Standard films that were adequate for local, short-cycle distribution are no longer sufficient. Specialty films with controlled barrier properties are the engineering response to this reality.
Regulatory Pressure Is Increasing
India’s food safety regulations (FSSAI), pharmaceutical packaging standards, and Extended Producer Responsibility (EPR) framework are all tightening. Medical packaging must meet specific sterilization standards. Food packaging must comply with material safety norms. Brands need films from suppliers who understand and meet these evolving requirements β not suppliers who chase the lowest cost per kilogram.
Sustainability Is Now a Commercial Requirement
India’s leading FMCG, food, and pharmaceutical brands have made public commitments to sustainable packaging. Specialty films β specifically Aerolam’s high-barrier monomaterial CPP films β provide a credible technical path to meeting those commitments without sacrificing packaging performance.
By replacing aluminium foil and mixed-material laminates with CPP-based high-barrier specialty films, brands can move toward recyclable packaging structures that comply with EPR targets while maintaining the barrier performance their products require.
