1. EVA lining: It is a packaging product used between the outer packaging of various fragile goods and the goods themselves, with different shapes and sizes based on the characteristics of the goods themselves.

Sponge is a porous material with good elasticity, and the elasticity varies depending on the pore density.

3. Inner tray function: It is used inside the packaging to provide protection for the product, as well as shock resistance, moisture resistance, and fixation.

4. Inner color: Black and white are commonly used (different colors can be customized according to needs), and the surface can be treated with flocking or velvet wrapping techniques to enhance the visual effect.
