eco thermal insert 3d model

Create a highly detailed and realistic 360-degree 3D model of a biodegradable temperature-buffering insert designed for lunch boxes and food storage containers. The product should have a flat rectangular shape with rounded corners, approximate dimensions of 250 mm × 150 mm × 12 mm, and a slim cushion-like appearance with soft stitched edges and slight flexibility. Use eco-friendly materials and textures, including a biodegradable butter paper outer layer, cotton cloth reinforcement layers, and a soy wax plus starch gel thermal core. The overall color palette should be natural beige, cream, and light earthy tones with a matte finish instead of glossy plastic. Add subtle green leaf graphics and the text “ECO THERMAL INSERT” on the front surface in a minimalist sustainable branding style. The model should clearly display accurate thickness, rounded edge geometry, realistic fabric textures, paper grain details, and visible seam stitching.
