Walki Experts video: Recyclable medium-barrier paper-based solution

What are the key features of Walki®Opti Seal that make it an excellent choice for flexible packaging?

Walki®Opti Seal is designed with an optimised PE-extrusion coating, offering excellent recyclability and barrier properties. Key features include a low seal initiation temperature for high packaging speeds, good mechanical properties with either brown kraft paper or white strong kraft paper, and effective water vapour and grease barriers. These attributes make it suitable for a wide range of products, particularly for bags used in bakery and frozen foods.

How does Walki®Opti Seal contribute to sustainability in the packaging industry?

Walki® Opti Seal enhances sustainability by being a highly recyclable, paper-based, heat-sealable material. The minimal PE coating allows it to be recycled with paper, ensuring a high fibre yield and reducing waste. With 90% or higher paper content, it is repulpable and promotes a circular economy. It is an easily implementable go-to solution when transitioning from paper/film laminates or multi- or mono-layered plastic solutions. The low reject ratio during the recycling process means that a high percentage of the fibre material is recovered, making it an efficient and environmentally friendly packaging solution.

Why is Walki® Opti Seal a good paper-based packaging solution for bakery and dried products?

Walki®Opti Seal is an excellent paper-based packaging solution for bakery and dried products for several reasons. Firstly, its heat-sealable properties ensure a secure closure, which helps to maintain the freshness and quality of the products inside. This is crucial for bakery items and dried goods, which need to be protected from moisture or moisture loss and external contaminants. Secondly, the material is highly recyclable due to its minimised PE coating, allowing it to be processed with paper recycling streams. Thirdly, with over 90% paper content, Walki®Opti Seal is repulpable and fits well into the circular economy model. Overall, Walki®Opti Seal combines functionality, sustainability, and usability making it a perfect choice for packaging bakery and dried products.

In what ways does the Walki®Opti Seal enhance the durability and sealability of flexible packaging?

The optimised PE-coating on Walki®Opti Seal significantly enhances the durability of flexible packaging by making it more resistant to punctures, tears, and ensuring robust protection during transportation and handling. Additionally, the superior sealability of Walki®Opti Seal, provided by the optimised PE-coating, allows for excellent heat-sealing properties, ensuring airtight and secure seals. This is crucial for maintaining the freshness and safety of food. Together, these features ensure that Walki®Opti Seal not only effectively protects the contents but also maintains the integrity and quality of the packaging throughout its lifecycle.

How does Walki®Opti Seal align with the EU Packaging and Packaging Waste Regulations (PPWR), and what are the benefits?

Walki®Opti Seal aligns with the EU PPWR by prioritising recyclability and reducing plastic usage. The PE-coated inside allows for easy recycling within established paper waste streams, ensuring compliance with regulatory requirements. This not only helps in meeting legal standards but also enables brand owners to reduce their environmental impact and potentially lower their EPR fees, CO2-footprint and packaging taxes by choosing high fibre-based materials.
