What is barrier coating, and why is it considered environmentally safe?
Barrier coating is a specialized inner layer applied to cups to prevent liquid penetration into or through the cardboard. Its environmental safety, particularly its biodegradability, depends on five key material properties: biological decomposition in soil, marine environments, and water, as well as suitability for home and industrial composting.
How does the material used for barrier coating affect packaging recycling?
Barrier coatings based on polyethylene (PE) are generally challenging to recycle. Packaging containing PE must first be sorted and processed separately from standard paper waste. Recycling these materials is only possible with specialized equipment.
The barrier coating used by Univest, however, is suitable for both industrial composting and traditional recycling at paper mills. This means paper cups with this coating can be disposed of in regular paper recycling bins.
Can all products be made with this coating?
Univest is currently the first manufacturer of this type of coating in Ukraine. We produce cups for hot and cold beverages, soup bowls, salad containers, and other fast-food packaging with barrier coatings. However, there are limitations for products requiring long-term storage, such as fermented dairy products (e.g., sour cream and yogurt).
Why is it important for packaging clients to switch to this type of packaging?
Choosing eco-friendly packaging with barrier coating offers several significant advantages for clients. Firstly, it addresses the growing consumer demand for sustainable and environmentally safe solutions. Using such packaging demonstrates environmental responsibility and enhances brand reputation. Additionally, it helps businesses comply with modern regulatory requirements aimed at reducing plastic usage, making them more adaptable to market changes.
Partnering with Univest gives clients access to high-quality, certified materials, enabling them to focus on growth while ensuring their packaging meets the highest standards of quality and environmental safety.
