How Food Packaging Materials Affect the Environment?

Author | Date: 12/16/2025

Why Food Packaging and the Environment Are Closely Linked?

Food packaging plays a vital role in modern life, ensuring our food remains safe, fresh, and convenient to transport. But while packaging protects our meals, it can also harm the planet. From non-recyclable plastics to energy-intensive materials, the environmental impact of food packaging has become a pressing issue.

With increasing global awareness around plastic pollution, landfill overflow, and sustainability, food businesses are under growing pressure to choose packaging materials that balance product safety with environmental responsibility. In this blog, we’ll explore how common food packaging materials affect the environment, what sustainable alternatives exist, and how your brand can make a difference.

What Is Food Packaging and Why Is It Necessary?

Food packaging does far more than simply hold products. It serves multiple crucial functions:

Protection – Prevents contamination and damage
Preservation – Extends shelf life, reducing food waste
Transport – Supports distribution and storage
Information – Provides labelling, nutritional details, and usage info
Branding – Communicates brand identity and trustworthiness

The real challenge lies in designing packaging that meets all these needs while remaining environmentally friendly.

Environmental Impact of Common Food Packaging Materials

1. Plastic Food Packaging

Plastic is everywhere—from sandwich wraps to takeaway containers. Its low cost, durability, and light weight make it a go-to material. However:

Takes centuries to decompose
Contributes to marine and soil pollution
Often non-recyclable or ends up in landfill
Microplastics enter food chains and water sources

While plastic food packaging is convenient, it’s one of the largest contributors to environmental degradation.

2. Paper and Cardboard Food Packaging

Paper-based packaging is often seen as a more sustainable choice:

Easily recyclable and biodegradable
Made from renewable resources
Lower carbon footprint than plastic

However, sourcing matters. Unsustainably harvested paper can lead to deforestation. FSC®-certified cardboard is ideal.

3. Glass Food Packaging

Glass has long been used in food packaging:

100% recyclable without loss of quality
Non-toxic and safe for food

However:

Heavy to transport (more emissions)
Requires high energy to produce

Despite its eco-credentials, glass isn’t always the best choice for lower carbon output.

4. Metal Food Packaging (Aluminium & Tin)

Metals like aluminium are highly effective for preserving food:

Infinitely recyclable
Excellent barrier properties
Extends product shelf life

But:

Mining and refining consume vast energy
Environmental cost during extraction phase

5. Biodegradable & Compostable Food Packaging

Bioplastics, sugarcane pulp, bamboo, and cornstarch-based packaging offer eco-alternatives:

Decompose naturally under the right conditions
Made from renewable materials
Reduce plastic dependency

These materials require proper industrial composting facilities and public education on disposal.

How Food Packaging Waste Harms the Environment?

Improperly managed food packaging contributes to:

Landfill overflow – Non-recyclables take up massive space
Marine pollution – Plastics and microplastics enter oceans
Wildlife harm – Animals ingest or get entangled in packaging
Toxic emissions – Incineration and breakdown of materials release harmful gases

These impacts are long-lasting and difficult to reverse.

The Role of Sustainable Food Packaging

Sustainable food packaging offers a smarter path forward:

Minimises environmental footprint
Supports recycling and reuse systems
Aligns with circular economy principles
Encourages consumers to choose greener brands

Eco-conscious packaging isn’t just good for the planet—it’s good for business too.

Eco-Friendly Alternatives for Food Packaging

Modern brands are switching to:

Kraft paper food boxes – Recyclable, compostable, rustic appeal
Cardboard containers – Custom printed and eco-safe
Compostable trays and wraps – Made from PLA, bagasse, or cornstarch
Reusable glass jars or tins – For premium, refillable products
Minimalist designs – Less material, more impact

Each option serves a different product niche while reducing environmental harm.

How Businesses Can Reduce Environmental Impact?

Simple shifts in your packaging strategy can create major positive change:

Choose certified recyclable or biodegradable materials
Avoid multilayer packaging that’s hard to separate
Design right-sized packaging to reduce waste
Use soy-based, food-safe inks for printing
Partner with responsible UK packaging suppliers

Educate your customers on how to responsibly dispose of packaging, including composting or recycling.

Why Eco Friendly Food Packaging Is the Future?

Stricter regulations on single-use plastics are increasing
Eco-conscious buyers are driving market trends
