Flexible Packaging Innovation at GLS Films: Protecting Food, Pharma, & FMCG Products

Flexible packaging plays a vital role in protecting, storing, and presenting products across today’s market.

In sectors like food, pharmaceuticals, and FMCG, it helps extend shelf life, streamline supply chains, and support sustainability goals.

With the global market expected to exceed USD 400 billion by 2030 and FMCG brands increasingly adopting sustainable formats, demand for high-performance flexible packaging is growing quickly.

Advances in materials now allow brands to reduce packaging weight by up to 30% through downgauging without compromising strength or barrier protection.

GLS Films , a trusted packaging company since 1993, operates at the forefront of this shift.

Through in-house R&D, advanced manufacturing, and deep material expertise, we deliver reliable packaging solutions using industrial-grade films.

We also leverage next-generation coating and metallised technologies to help brands meet evolving performance and sustainability requirements.

In this article, you will explore how modern packaging solutions are advancing and how innovations in industrial grade films and coatings and metallised films are building the future of flexible packaging.

Understanding the Science Behind High-Performance Packaging

Barrier technology is a cornerstone of modern flexible packaging, ensuring products remain fresh, safe, and effective.

Two key measures define its performance:

• OTR (Oxygen Transmission Rate): Indicates how much oxygen can pass through the packaging.
• WVTR (Water Vapour Transmission Rate): Indicates how much moisture can penetrate the packaging.

The lower these values, the stronger the protection. This is crucial for maintaining product quality: snacks stay crisp and flavours intact, while moisture-sensitive items such as powders and pharmaceuticals retain their stability and effectiveness.

Advanced Materials: Alox and Metallised Films

GLS Films drives innovation in packaging for food, FMCG, and pharma through advanced coating and metallised films, helping brands enhance protection, presentation, and sustainability.

Our Alox (Aluminium Oxide) coated films combine high barrier protection with transparency, allowing products to be showcased safely while supporting sustainable packaging practices.

Building on this, our metallised films add an extra layer of protection against oxygen, moisture, and light while remaining flexible and lightweight.

These high-performance films are ideal for snacks, dairy, ready-to-eat meals, and pharmaceutical products, extending shelf life by up to 25–30% while helping brands achieve their sustainability goals.

Retort Packaging: A Breakthrough Innovation

The GALTR301 Alox Retortable Film from GLS Films withstands high temperatures up to 120°C for 30 minutes, ideal for ready-to-eat meals, sauces, and packaged curries.

Unlike traditional aluminium foil laminates, which restrict recyclability and product visibility, our Alox-based retort films tackle these limitations, delivering:

• Exceptional heat resistance
• Superior barrier protection
• Transparent, see-through packaging

By combining safety, durability, and product visibility, GLS Films is redefining flexible packaging, helping brands enhance both shelf appeal and sustainability.
