What is buffer packaging?

Buffers are a type of corner or edge protective packaging which are developed bespoke to your product, supply chain and sales channel needs. All our buffers are paper-based, available in corrugated cardboard and honeycomb (or in combination), and designed to provide optimal levels of strength and protection to meet any challenges in the supply chain.

Why is now the time to change to paper-based edge protectors and buffers?

Paper-based buffers are a sustainable alternative to EPS and plastic edge protectors. Paper is one of the most sustainable materials available: it’s recyclable, renewable and biodegradable and is subsequently the world’s most collected and actually recycled material.

Sustainability is a driving and undeniable factor in consumers' buying decisions and packaging is a tangible symbol of a company’s wider sustainability agenda. By switching from EPS to cardboard edge protectors, you can improve the customer perception of your brand. Cardboard corner and buffers are a great option for consumers as they can be recycled in the regular kerbside cardboard recycling system.

The right choice for the consumer, the product and the planet!
