A4 Transparent Insert Sheet (D1)

The A4 Transparent Insert Sheet (D1) is a clear, smooth plastic sheet designed to sit inside resin molds, tray frames, or wooden bases — giving your epoxy and UV resin pours a clean, non-stick surface to cure against. Whether you are making resin trays, coasters, photo frames, or decorative panels, this sheet helps you achieve a glossy, bubble-free base layer without the resin sticking to your work surface.

Cut to A4 size (approximately 21 cm × 29.7 cm), this insert sheet is thin, flexible, and easy to trim with scissors or a craft knife to fit custom mold sizes. It works equally well with UV resin, 2-part epoxy resin, and casting resin — making it a handy consumable for hobbyists and small resin businesses alike.

• A4 size (approx. 21 × 29.7 cm) — fits standard tray molds and wooden frames with minimal trimming
• Transparent and smooth surface allows resin to cure with a clear, glossy finish underneath
• Non-stick properties help release cured resin cleanly without tearing or surface damage
• Compatible with UV resin, 2-part epoxy, and liquid casting resin
• Flexible and easy to cut — trim to any custom shape using scissors or a craft knife
• Reusable for multiple pours when handled with care, reducing material waste
• Useful as a protective liner on work tables to prevent resin spills from sticking

How to Use

Place the transparent sheet flat inside your mold, tray, or frame before pouring resin. Ensure edges are pressed down so resin does not seep underneath. Once the resin is fully cured, gently peel the sheet away for a smooth, glossy surface. Trim the sheet to size with scissors if your mold is smaller than A4.

Safety Tips

Always wear nitrile gloves when working with liquid resin on or around this sheet. Keep uncured resin away from skin and eyes. Work in a well-ventilated space. Dispose of resin-coated sheets responsibly — do not burn.
