From Glass to PET

The Packaging Shift Redefining Multiple Industries 

A quiet revolution is unfolding on shelves across Europe. From gourmet nut jars in Berlin to spirits in Stockholm and instant coffee in Barcelona, more and more brands are making the switch from glass to PET. And this is not merely a trend — it is a movement gathering momentum, redefining packaging standards across sectors. 

At Embaco, we are at the heart of this transformation. As one of Europe’s foremost suppliers of PET packaging, we have observed a notable surge in companies enquiring about PET alternatives to their traditional glass formats. Particularly within categories such as instant coffee, alcohol and spirits, nuts and spreads, herring, and sauces, the shift is not only evident – it is accelerating. 

The Glass Legacy — And Its Limitations 

Let us be honest: glass has long represented the benchmark for premium packaging. It feels luxurious, boasts a long-standing heritage, and is infinitely recyclable. However, it brings a set of trade-offs that are increasingly difficult to justify in a fast-paced, sustainability-driven, and cost-conscious market. 

Glass is heavy. It breaks. It requires more energy to produce and transport. And as logistics costs climb and sustainability targets tighten, more companies are asking the key question: is glass still worth it? 

Why PET Is Gaining Ground 

PET (Polyethylene Terephthalate) is not new, but the technology and design capabilities associated with it have advanced significantly in recent years. What was once seen as a “cheap” alternative is now a robust, adaptable, and aesthetically pleasing material that offers substantial advantages: 

1. Lightweight Efficiency 
   PET can be up to 90% lighter than glass. This equates to significant savings on shipping, a reduced carbon footprint, and improved ergonomics for the end user. 

2. Shatterproof and Durable 
   Unlike glass, PET does not shatter. This is a major advantage for brands concerned with safety in transit and performance on the shelf. 

3. Lower Carbon Footprint 
   The carbon footprint of PET manufacturing and transportation is considerably lower than that of glass. A 2020 study by Plastics Europe reported that PET bottles emit approximately 77% less CO2 across their life cycle compared to glass. 

4. Fully Recyclable 
   PET is 100% recyclable and widely collected throughout Europe. As recycling infrastructure improves and rPET (recycled PET) becomes more accessible, circular packaging is increasingly within reach. 

5. Design Flexibility 
   Contemporary PET production allows for premium finishes, embossing, and even the visual and tactile qualities of glass — without its limitations. It no longer means compromising on design. 

Sector Spotlight: Who Is Leading the Change 
 

Instant Coffee 

In this category, convenience is paramount. PET containers are lighter, easier to reseal, and travel better. For brands shipping internationally or supplying retail chains, the savings in transport alone make a strong case. From a branding perspective, PET jars now offer clarity and shelf appeal comparable to glass. 
 

Alcohol and Spirits 

Even in this traditionally glass-dominated sector, change is afoot. Travel retail, festivals, and events are increasingly opting for PET for its safety and practicality. We have supported distilleries launching limited-edition PET packaging tailored for specific campaigns or sampling initiatives. 

PET does not have to imply “budget.” With tailored embossing, tinted finishes, and refined closures, the final product can appear just as premium — and often more contemporary — than glass.

Nuts and Spreads 

This sector thrives on accessibility and freshness. PET jars offer strong oxygen barriers and excellent resealability. The clarity of PET enables consumers to “see what they buy” — a major plus for health-conscious shoppers seeking natural, transparent choices. 

Additionally, PET integrates seamlessly with automated filling lines and e-commerce logistics, making it ideal for emerging DTC brands. 
 

Herring and Sauces 

Traditionally, these categories have leaned on glass to signal freshness and authenticity. However, as brands pivot towards younger audiences and aim for stronger sustainability credentials, PET emerges as a smart alternative. Modern PET containers are compatible with hot-fill processes and provide airtight seals, preserving contents without compromising shelf life. 

We have observed Scandinavian brands in particular embracing this change, balancing heritage with innovation. 

The Sustainability Equation 

A common misconception is that glass is inherently more sustainable due to its recyclability. However, this view overlooks the significant energy required for glass production and transport. A full life cycle assessment offers a clearer picture: when PET is responsibly collected and recycled, it outperforms glass across several environmental indicators. 

In fact, many of our clients report reductions of up to 60% in packaging-related emissions when transitioning from glass to PET. 

This does not even account for rPET. At Embaco, we increasingly supply rPET solutions that meet both performance and sustainability standards. rPET reduces reliance on virgin materials and contributes to a tangible circular economy — something today’s eco-aware consumer appreciates.

Logistics, Cost, and Scalability 

Glass is costly to transport. It is fragile and demands substantial protective packaging. PET, in contrast, is a logistics asset. Its lighter weight results in lower shipping costs and reduced emissions. Its durability decreases damage and returns. And in a time of strained supply chains, PET’s scalability offers an additional competitive edge. 

A Cultural Shift 

This is not just a material evolution — it is a shift in mindset. Brands today demand flexibility. They need packaging that performs, protects, promotes, and reflects their values. 

Let us be candid: modern consumers are not falling in love with heavy, breakable jars. They seek smart, sustainable, and stylish packaging that aligns with their lifestyle. 

As one of Europe’s most progressive PET packaging suppliers, we are proud to collaborate with brands that are ready to challenge convention. 

Looking Forward 

This shift from glass to PET is not about abandoning tradition. It is about progression. Glass still has its place. But for many, PET offers the agility, efficiency, and environmental performance necessary to succeed in today’s dynamic market. 

If your brand is considering the transition from glass to PET, now is the time to explore. The tools, technologies, and materials are already in place – and so are we. 

Let us shape the future of packaging – one smart change at a time.
