Acrylic vs Glass vs PETG: A Direct Comparison

When you choose a material for your food displays, you must look at more than just the price tag. The right choice balances safety, strength, appearance, and long-term value. This direct comparison of Acrylic vs glass vs PETG will help you understand the key differences.

Food Safety & FDA Compliance

You must ensure your displays meet health standards, especially when they directly contact food. Each material handles this differently.

• Vidrio: This material is a natural choice for food safety. Glass is non-porous and inert. It will not leach chemicals into food, making it perfectly safe without needing special grades.
• PETG: You can feel confident using PETG in your bakery or cafe. It is inherently food-safe and easily meets FDA compliance standards for food contact.
• Acrílico: You need to be specific when choosing acrylic. Standard acrylic is not automatically food-safe. You must select a “food-grade” option. The FDA regulates these materials under 21 CFR 177.1010. Manufacturers must have their clear, colorless sheets independently certified to meet these requirements for use with food.

Durability & Impact Resistance

Your displays need to withstand the daily hustle of a busy commercial environment. Impact resistance is crucial for both safety and longevity.

• PETG: This is your most durable option. PETG is virtually unbreakable and will not shatter into dangerous shards upon impact. This makes it the safest and most reliable choice for high-traffic areas where bumps and knocks are common.
• Acrílico: Acrylic offers excellent impact resistance, often 10 to 20 times stronger than glass. It provides a great deal of durability. However, a sharp, direct blow can still cause it to crack.
• Vidrio: Standard glass is brittle. Tempered glass is stronger but can shatter into many small pieces if it breaks. This poses a significant safety risk in busy public spaces, making it the least durable option against impacts.

Visual Clarity & Aesthetics

You want your products to look their best. The clarity of your display case is essential for showcasing your food items attractively.

Light Transmission at a Glance 💡

• Acrílico: 92%
• Vidrio: Up to 92%
• PETG: 86% – 90%

Acrylic often provides the best optical clarity, allowing 92% of light to pass through. This can make it appear even clearer than standard glass. However, its surface is softer and can scratch. Glass also offers high clarity and is extremely scratch-resistant. Thicker sheets of glass can sometimes have a slight green tint. PETG provides very good clarity, though slightly less than acrylic. It is also the softest of the three, making it more prone to scratching than acrylic.

The refractive index also affects how your customers see your products. Acrylic has a refractive index of 1.49, which is slightly different from glass. This can cause minor visual distortion, but it is rarely noticeable in display applications.

For displays exposed to sunlight, UV resistance is key for long-term clarity.

Material	UV Resistance	Long-Term Effect
Acrílico	Excellent	Maintains optical clarity over time.
PETG (Standard)	Moderate	Can yellow and become hazy with sun exposure.
Vidrio	Excellent	Unaffected by UV radiation.

Cost-Effectiveness

Your budget involves more than just the initial purchase price. You should consider fabrication, installation, and potential replacement costs to understand the true lifetime value. The debate of Acrylic vs glass vs PETG often comes down to this balance.

• Acrílico: This is typically your most budget-friendly option for the material itself. It gives you a high-end look for a lower initial investment.
• PETG: PETG costs more than acrylic but is generally less expensive than glass. Its real value comes from its durability. Because it resists breaking, you will spend less on replacements over time, offering excellent long-term value.
• Vidrio: Glass has the highest initial cost. A 1/4-inch thick sheet of tempered glass can cost you between $12 and $15 per square foot. Custom cuts and edgework will add to this price. Its weight and fragility also make replacement expensive.

Fabrication is another major cost factor. PETG is the easiest to work with. You can cut, drill, and bend it without it cracking, which lowers labor costs and reduces material waste. Acrylic is also easy to machine but can crack during bending if not handled correctly. Glass is the most difficult and expensive to fabricate, requiring specialized tools and expertise.

Weight & Installation

The weight of your display material directly impacts installation complexity and cost. Heavier materials require more labor and more robust support structures.

Feature	Glass Displays	Acrylic & PETG Displays
Weight	Very heavy. A 1/4″ sheet weighs over 3 lbs per sq. ft.	Lightweight. A 1/4″ acrylic sheet weighs about 1.5 lbs per sq. ft.
Support	Requires reinforced frames and heavy-duty hardware.	Can use lighter, less expensive support structures.
Handling	Difficult and requires multiple people for safe installation.	Easy for one person to handle and install.

Because acrylic and PETG are about half the weight of glass, you save on shipping costs and labor. The easier handling reduces installation time and makes it a much simpler process overall.

Chemical Resistance & Cleaning

Keeping your food displays clean and sanitized is non-negotiable. The material you choose determines which cleaners you can safely use.

• Vidrio: Offers excellent chemical resistance. You can clean it with almost any standard glass cleaner without worrying about damage.
• PETG: Has good chemical resistance, better than acrylic. It can handle a wider variety of cleaners, but you should still use soft cloths to avoid scratching the surface.
• Acrílico: This material requires the most care. You must avoid harsh chemicals. Cleaners containing ammonia (like Windex), alcohol, or acetone will cause crazing—a network of fine cracks that clouds the material and weakens its structure.

Cleaning Tip for Acrylic ✅ Always use a mild soap and water solution or a specialized product like Novus #1 Plastic Clean & Shine. These products clean effectively without causing damage, helping you maintain the clarity and strength of your acrylic displays.
