You’ll see a few common terms when you’re shopping for clear plastic frame covers. The most common types include:

• Clear acrylic panels (acrylic sheet) for a rigid, glass-like look.
• Polystyrene panels for lightweight, shatter-resistant covers.
• PET clear sheets for thin, flexible protection.
• PVC clear panels for general craft and display use.
• Polycarbonate sheets for higher impact resistance.

Acrylic is sometimes described using a popular trade name for acrylic sheet. On product pages, check the material, thickness (in mm or inches), and dimensions. Most panels arrive with protective films on both sides to help prevent scratches during shipping; peel these away right before framing.

If you’re trying to save compared with acrylic sheet, consider these options:

• Polystyrene: Lightweight and shatter-resistant, commonly used in ready-made frames. It can be more budget-friendly, but may scratch more easily than rigid acrylic.
• PET clear sheets: Thin, flexible covers that work well for posters and large prints where rigidity isn’t critical.
• Thin acrylic sheets (for example, around 0.02–0.04 in): Often more cost-conscious than thicker panels while still offering clarity.

The right pick depends on how the frame will be used. For high-traffic areas or larger frames, more rigidity may be helpful. Review the thickness, material, and transparency details on the product page to balance clarity, durability, and cost.

You can find clear plastic sheets online at Walmart and, in some areas, in stores. Here’s a quick way to browse:

1. Search for terms like “clear acrylic sheet,” “replacement frame panel,” or “clear plastic sheet.”
2. Filter by size (e.g., 5x7, 8x10, 24x36) and thickness (mm or inches).
3. Check materials noted in the description: acrylic, polystyrene, PET, PVC, or polycarbonate.
4. Select fulfillment options available in your area, such as delivery, shipping, or pickup.

Product pages typically list exact dimensions, usable area, and whether there are protective films. If you’re outfitting several frames, multi-packs can be a convenient way to get consistent panels for each size.

They’re essentially the same material. The term you’re comparing acrylic to is a widely used trade name people often use for acrylic (PMMA) sheet. Differences you’ll notice when shopping are usually about the sheet’s thickness, rigidity, and manufacturing method (such as cast or extruded), not the basic material.

• Material: Both refer to clear acrylic plastic used as a glass alternative.
• Variations: Products vary in thickness, clarity, and surface protection.
• What to check: Size, thickness (e.g., 1 mm or 1/8 in), note of protective film, and any mention of impact resistance.

Select the option that matches your frame size and the level of rigidity you prefer.

Gentle cleaning helps keep plastic covers clear without scratching:

1. Rinse off loose dust with lukewarm water.
2. Wash with a drop of mild dish soap and a soft, non-abrasive cloth.
3. Rinse again, then blot dry with a clean microfiber towel to reduce streaks.
4. Avoid ammonia or abrasive cleaners, scouring pads, and dry wiping, which can cause haze.
5. Minimize static by using a plastic-safe cleaner or a slightly damp microfiber cloth.
6. Keep protective film on until installation, and handle by the edges to reduce fingerprints.

These steps can help maintain clarity, though results may vary based on the material (acrylic, PET, polystyrene) and how the panel is used and displayed.
