Print and packaging manufacturer: Advancing sustainable packaging through Zero-Polymer design innovation

Overview

Knight R&D partnered with a specialist manufacturer of sustainable print and packaging solutions with more than three decades of industry experience. Operating in a highly competitive and environmentally driven market, the company has prioritised R&D investment to develop advanced manufacturing and packaging systems that reduce environmental impact without sacrificing performance.

The project focused on eliminating plastic and lamination from packaging solutions while maintaining structural integrity, manufacturability, and cost-efficiency.

The technological context

Across the packaging industry, pressure to remove plastic has intensified. However, traditional alternatives often rely on lamination or corrugated reinforcement to maintain durability, introducing new cost, recyclability, and assembly challenges.

The company sought to pioneer a new class of zero-polymer packaging assemblies capable of delivering equivalent structural performance using thinner, pulp-based substrates.

This required advancement not only in material selection, but in structural design and geometric engineering.

The Engineering Challenge

The core technological uncertainty lay in whether thinner, recyclable substrates could deliver sufficient durability and product protection without lamination or reinforcement.

Achieving this required the development of new geometric net configurations that balanced strength, flexibility, and material efficiency. Packaging systems needed to securely house products of varying shapes and weights, while remaining compatible with automated manufacturing processes and constrained press sheet sizes.

Further complexity arose in designing proprietary locking mechanisms capable of securing products internally without compromising material integrity or increasing assembly complexity.

These challenges demanded iterative design cycles, prototyping, stress testing, and mechanical refinement to achieve reproducible performance at scale.

Knight R&D’s Approach

We worked directly with the company’s design and production specialists to isolate genuine technological advancement within their packaging redesign programme.

Our analysis focused on structural optimisation of zero-polymer assemblies, geometric net engineering, substrate performance limitations, and locking mechanism experimentation. Each area was assessed against HMRC’s criteria to evidence technological uncertainty and advancement beyond routine product iteration.

The result was a structured, defensible R&D submission that clearly articulated the innovation embedded within sustainable design engineering.

The Outcome

The claim secured a meaningful tax benefit, reflecting the scale of innovation undertaken.

Beyond the financial return, the project enabled the company to pioneer plastic-free packaging systems that reduce material usage, enhance recyclability, and improve manufacturing efficiency. The resulting designs set a new internal benchmark for sustainable packaging performance.

Why It matters

Sustainability-driven innovation frequently involves genuine technological uncertainty, particularly where environmental performance must be balanced against cost, durability, and scalability.

When properly analysed, advancements in material engineering and structural design often qualify as R&D under UK legislation. Even where innovation occurs within manufacturing environments rather than laboratories.
