Choosing the right material for a display case is essential for businesses that need to protect, showcase, and preserve their valuable products or artefacts. Whether you’re in retail, museums, exhibitions, or any other industry that requires high-quality display solutions, selecting the best material can significantly impact durability, aesthetics, and functionality.
At Dipec, we specialise in manufacturing bespoke plastic display cases using acrylic, polycarbonate, PETG, and PVC, each offering unique advantages tailored to different business and individual use-case needs (pardon the pun).
In this comprehensive guide, we’ll explore these plastic materials, compare their strengths, and help you determine the most suitable option for your display requirements.
Why Choosing the Right Display Case Material Matters
The material used in your display case affects:
- Clarity & Aesthetics – How well the contents are showcased.
- Durability & Strength – The level of protection against impacts and wear.
- Security Features – Lockability and resistance to tampering.
- UV & Environmental Protection – Prevention of light damage and degradation.
- Cost-Effectiveness – The balance between affordability and performance.
So, with that said, let’s explore the most popular plastic materials used for display cases and how they compare.
Acrylic (PMMA – Polymethyl Methacrylate)
Acrylic is one of the most widely used materials for display cases due to its exceptional clarity, versatility, and lightweight properties.
Key Benefits
✅ Crystal Clear Transparency – Acrylic has 92% optical clarity, providing an almost glass-like appearance without distortion.
✅ Lightweight & Shatter-Resistant – Unlike glass, acrylic is much lighter and resistant to shattering, making it safer for high-traffic environments.
✅ UV Protection – Special UV-resistant acrylic options protect delicate items from light damage.
✅ Easy Fabrication & Customisation – Acrylic can be cut, shaped, and polished to create bespoke display cases tailored to unique requirements.
✅ Cost-Effective – While offering premium visual appeal, acrylic remains an affordable option compared to glass or high-end plastics.
Best Use Cases
- Retail – Showcasing jewellery, electronics, and high-end products.
- Memorabilia – Ideal for sports jerseys, collectibles, and autographed items.
- Exhibitions & Galleries – Offering maximum visibility while protecting artefacts.
Potential Drawbacks
⚠️ Can scratch easily (but can be polished to restore clarity).
⚠️ Less impact-resistant than polycarbonate.
💡 Tip: If your display case will be placed in direct sunlight, consider using UV-resistant acrylic to prevent discolouration and fading of valuable items.
Polycarbonate (PC) – The High-Strength Option
Polycarbonate is one of the strongest transparent plastics, offering unmatched impact resistance and durability.
Key Benefits
✅ Extremely Durable – Up to 250 times stronger than glass, making it ideal for high-security applications.
✅ Impact-Resistant – Perfect for environments where accidental knocks or vandalism are concerns.
✅ UV Protection & Fire Resistance – Helps prevent degradation from sunlight exposure.
✅ Lightweight – Despite its strength, polycarbonate remains lighter than glass.
Best Use Cases

- Protective Display Cases – Used for safeguarding coins, antiques, and luxury items.
- Outdoor Exhibits – UV resistance makes it suitable for external display environments.
Potential Drawbacks
⚠️ More expensive than acrylic.
⚠️ Susceptible to minor surface scratches (can be treated with coatings).
❓ Did you know? Polycarbonate is 250 times stronger than glass and is commonly used for bulletproof windows and security screens! That’s why it’s a top choice for high-security display cases.
PETG (Polyethylene Terephthalate Glycol) – A Flexible & Food-Safe Option
PETG is a strong, impact-resistant plastic that is also food-safe, making it a preferred choice for retail and hospitality display cases.
Key Benefits
✅ Highly Impact-Resistant – More durable than acrylic, reducing breakage risks.
✅ Food-Safe & Hygienic – Often used in food display applications.
✅ Easily Moulded & Fabricated – Allows for creative designs and unique shapes.
✅ Less Prone to Cracking – More flexible than acrylic, reducing brittleness over time.
Best Use Cases
- Retail & Hospitality – Food display cases, POS displays, and commercial showcases.
- Exhibitions – Durable yet flexible material for portable trade show displays.
Potential Drawbacks
⚠️ Lower clarity than acrylic.
⚠️ Can be prone to yellowing over time if exposed to high UV levels.
💡 Tip: Looking for a food-safe display case? PETG is a great choice! It’s commonly used in bakeries, supermarkets, and food exhibitions due to its hygienic properties.
PVC (Polyvinyl Chloride) – Budget-Friendly Industrial Choice
PVC is a cost-effective, durable plastic primarily used in industrial or commercial settings where high transparency is not a priority.
Key Benefits
✅ Highly Durable & Moisture-Resistant – Suitable for humid or chemical-prone environments.
✅ Affordable Alternative to Other Plastics – A budget-friendly choice for bulk protective cases.
✅ Chemical & Corrosion Resistant – Ideal for industrial applications.
Best Use Cases
- Industrial & Commercial Applications – Protective covers for equipment and workspaces.
- Low-Cost Storage Displays – Where aesthetics are secondary to durability.
Potential Drawbacks
⚠️ Less transparent than acrylic or polycarbonate.
⚠️ Not as visually appealing for high-end displays.

Which Material Is Best for Your Display Case Needs?
| Material | Key Benefits | Best For |
|---|---|---|
| Acrylic | High optical clarity, lightweight, shatter-resistant, UV-resistant options | Museums, retail displays, memorabilia showcases |
| Polycarbonate | Extremely impact-resistant, durable, good optical clarity, UV-resistant | High-security applications, protective cases, industrial settings |
| PETG | Strong, impact-resistant, food-safe, easy to thermoform | Retail environments, food displays, commercial applications |
| PVC | Cost-effective, durable, resistant to chemicals and moisture | Industrial protective cases, budget-conscious solutions |
For high-end retail displays, acrylic is the best choice. If maximum durability is needed, polycarbonate is the superior option. For food-safe displays, PETG is ideal, while PVC suits industrial use.

FAQs
The most durable material for display cases is polycarbonate. It is up to 250 times stronger than glass, making it highly impact-resistant and virtually shatterproof. This makes it ideal for high-security applications, museums, and retail settings where durability is essential. Unlike glass, which can break easily, polycarbonate can withstand heavy impacts, making it a preferred choice for protective display cases in busy environments. While acrylic is also durable and lightweight, polycarbonate offers superior toughness for demanding applications.
Acrylic is widely used for display cases due to its crystal-clear transparency, lightweight nature, and shatter resistance. It offers excellent optical clarity, allowing for an unobstructed view of the displayed items. Additionally, UV-resistant acrylic options are available, preventing sun damage to delicate objects. Compared to glass, acrylic is much lighter, making it easier to install, move, and handle. This makes it a top choice for museum exhibits, retail displays, and memorabilia showcases.
PETG (Polyethylene Terephthalate Glycol) and acrylic are both popular transparent plastics, but they have distinct properties:
– Acrylic offers superior optical clarity and a polished, high-end finish, making it ideal for high-end retail displays, museums, and showrooms.
