From TPE Material to Shelf Liners: Uwin’s Customer-Driven Development

New product development sometimes begins with a customer’s feedback on an existing product.

While discussing a shelf liner project with a Chinese home goods brand, we learned that the customer wanted to develop a shelf liner with better slip resistance and a longer service life.

With this goal in mind, we moved beyond commonly used EVA and PVC materials and began developing a new TPE shelf liner. TPE combines rubber-like elasticity with the processing capabilities of thermoplastics. Its formulation and hardness can be adjusted to achieve different levels of softness, flexibility, and tactile feel. These characteristics gave us a material foundation for developing a soft, flexible shelf liner while allowing room to accommodate different requirements for feel, installation, and rolling.

We then combined the material with product thickness and surface texture design to develop a finished product for practical use. From TPE material evaluation to sample refinement and finished product approval, this article explains how Uwin translated customer requirements into specific product design decisions.

Customer Requirements: Finding a New Solution for Existing Shelf Liners

At the beginning of the project, the customer wanted to add a new shelf liner to its existing home organization collection, focusing on reducing shifting during everyday use, improving how the liner conforms to the installation surface, and making cleaning easier.

The product was intended primarily for kitchen cabinets, drawers, and shelves, with cabinet surfaces underneath and dishes, kitchenware, and everyday storage items on top. The customer wanted a liner that would be less likely to move when items were picked up or put away, while also feeling soft, being easy to cut to fit, and being convenient to remove for cleaning.

Through further discussions, we translated these requirements into specific development objectives:

Among these requirements, we prioritized reducing shifting when items were picked up or put away, while also considering softness, installation, and cleaning. We separately considered the liner’s stability against the cabinet surface and its contact with the items placed on top.

These requirements guided our material selection. We began evaluating TPE material and considered thickness, surface texture, and processing methods to find a finished product solution that would fit the customer’s product positioning.

Material Selection: Why We Chose TPE for This Project

We chose TPE for this shelf liner primarily because of its rubber-like flexibility and elasticity. These properties relate to the material’s internal structure: flexible regions deform under force, while supporting hard regions help maintain the overall structure and allow the material to recover its shape once the force is removed.

For slip resistance, TPE’s flexibility creates opportunities for closer surface contact. Under the weight of stored items, the material can deform slightly to conform to small surface irregularities, increasing actual contact. Deformation and energy loss as an elastic material slides can also contribute to frictional resistance. An appropriate TPE formulation can therefore give a shelf liner a grippy feel, although its final frictional performance still depends on hardness, formulation, and the contact surface.

For tactile feel, TPE combines softness with elastic recovery. When pressed or stretched, its flexible molecular chains can change configuration; once the force is removed, the material’s structure encourages recovery. This soft, springy response is the feel we wanted to achieve in the new product. When comparing it with EVA shelf liners, the specific degree of springiness also depends on the hardness, thickness, and foam structure of both products.

Product Design: Translating Requirements into Surface Texture, Thickness, and Product Format

After establishing the material direction, we translated the customer’s requirements into specific product details.

Surface Design: Addressing Contact and Shifting

This TPE shelf liner uses different textures on its two sides: a regularly arranged raised diamond texture on the top and a fine recessed dimple texture on the underside. These surfaces address contact with stored items above and the cabinet surface below.

On the top, we combined the raised texture with TPE’s softness and elasticity, aiming to keep dishes, kitchenware, and storage items more stable and reduce sliding during everyday handling. On the underside, we used a shallow recessed texture and treated contact between the liner and cabinet surface as a separate design consideration, aiming to reduce the tendency for the liner to move along with items as they are picked up or put away.

We therefore focused on two related aspects of performance: whether items could remain stable on the liner and whether the liner could stay in position on the cabinet surface. Subsequent sample evaluations also examined these two contact relationships separately, using actual cabinet surfaces and storage items to observe movement during picking up, putting away, pushing, and pulling, and to check whether the two-sided texture design met expectations.

Dimensions and Packaging: Supporting the Customer’s Sales Channels

This TPE shelf liner comes in rolls, allowing users to cut it to fit cabinets, drawers, or shelves. For different product positioning needs, we can discuss roll width, length, and color with customers to balance ease of use and sales requirements.

For packaging, we can discuss options such as individually packaged rolls, branded labels, paper sleeves, or printed retail boxes based on retail, e-commerce, or wholesale requirements. We can also coordinate product information, cutting and cleaning instructions, barcodes, and outer carton markings.

We treat dimensions and packaging as part of finished product development and confirm them alongside sample specifications, helping align everything from product use and brand presentation to carton packing and transportation with the customer’s purchasing plan.

Performance Verification: Checking the Finished Product Against Development Objectives

After refining the samples, we used internal performance testing and practical installation evaluations to check whether this TPE shelf liner met the original development requirements. We considered both the material’s properties and how complete samples performed in cabinet and drawer settings, including their interaction with contact surfaces and stored items.

The project’s key evaluation areas included slip resistance, recovery after compression, flatness after installation, and appearance and condition after cleaning. Slip resistance evaluations separately considered friction between the liner and cabinet surface and between stored items and the liner. Elasticity and installation evaluations focused on recovery after compression, bending, and unrolling. For everyday maintenance, we cleaned samples using the proposed cleaning method and checked for visible deformation, surface damage, or other changes that could affect use.

Slip Resistance and Friction Performance

In internal friction testing, we took three measurements across the top surface of a gray TPE sample in the transverse direction. The coefficients of friction were 0.65, 0.63, and 0.61, with an average of 0.63. All three exceeded the ≥0.3 acceptance criterion used for this test.

The average coefficient of friction of 0.63 indicates frictional resistance between the sample’s top surface and the test contact material. In an everyday setting, the intended benefit is easy to understand: when a user picks up a dish, nearby storage items should be less likely to slide because of a slight bump.

Cleaning and Everyday Maintenance

This TPE shelf liner has a waterproof surface. Dust or small stains can be wiped away with a damp cloth. After cleaning, allow the liner to dry before putting it back, making everyday cabinet and drawer maintenance convenient.

The raised texture on the top means that items primarily contact the raised areas, reducing direct friction against the recessed areas and providing some protection against scuffing. To reduce damage during use, avoid scraping the liner with sharp objects and lift heavier items before moving them.
