As governments continue to crack down on single-use plastics, many food businesses are now seeking eco-friendly packaging solutions that don’t compromise on performance. Traditional polystyrene containers once a go-to for insulation and cost-effectiveness are being phased out due to their environmental impact and limited recyclability.

At GreenFeel, we provide compliant alternatives to polystyrene that meet the demands of modern foodservice: KP Infinity® and bagasse packaging. Here's what makes them stand out.

KP Infinity®: The Advanced EPP Alternative to Polystyrene

KP Infinity® packaging is made from Expanded Polypropylene (EPP), a highly durable and lightweight material known for its excellent insulation and resistance to moisture and chemicals. EPP provides a reliable alternative to polystyrene, delivering consistent performance in demanding foodservice environments.

Key Features:

Fully recyclable, unlike polystyrene, KP Infinity® can be commercially recycled multiple times.
Excellent water resistance with no coatings needed
Superior thermal protection, keeping food hotter for longer
Microwave-safe for convenient reheating
Outstanding resistance to acids, alkalis, and hot oils, ideal for a variety of foods
Lightweight yet durable, easing handling

Bagasse Packaging: Compostable and Plant-Based

Bagasse packaging is made from sugarcane fibre, a renewable resource. While they are not recyclable, bagasse packaging is compostable and breaks down naturally in commercial composting facilities, making it a plastic-free, eco-conscious option.

Key Features:

Compostable and biodegradable — supports sustainable waste management by decomposing after disposal
Good resistance to grease and moisture, suitable for many food types
Microwave-safe for convenient reheating
Plastic-free, compliant with single-use plastic bans

Carton Board Packaging: Eco-Friendly and Budget-Friendly

Carton board food packaging is made from paperboard and is often lined with a thin layer of plastic (usually PE) to prevent leakage from oily or wet foods. While the base material is renewable and recyclable, the plastic lining can limit recyclability through standard paper recycling systems.

Key Features:

Plastic-lined for water and grease resistance performs well with hot or oily foods
Partially recyclable, not always accepted in standard paper recycling due to the lining
Rigid and stackable, good structural integrity for packaging and transport
Cost-effective for large-scale foodservice
Not microwave-safe unless specifically manufactured

Choosing the Right Polystyrene Alternative

If you want high-performance insulation and recyclability, KP Infinity® is an excellent choice. For those prioritising compostability and plant-based materials, bagasse packaging provides a microwave-safe, plastic-free solution. Both help your business meet regulations and consumer demand for sustainable food packaging.
