Transparent and brown PET sheet refers to a type of plastic material made from polyethylene terephthalate (PET) resin, commonly used in packaging, signage, and various industrial applications. While PET is typically transparent, the addition of brown pigment during the manufacturing process imparts a brown color to the sheet. This material retains the transparency characteristic of PET while offering a brown tint, providing aesthetic appeal and potentially serving specific functional or design purposes where clarity with a tint is desired, such as in displays or protective coverings.

What is the lifespan of your PET sheets?
- Service Life
- PET sheets are known for their high durability and, depending on usage conditions, typically last between 5 to 10 years.
- In indoor environments (not exposed to direct sunlight or extreme humidity), their lifespan can exceed 10 years.
- Environmental Factors
- UV Exposure: Continuous outdoor use under sunlight may cause yellowing or loss of clarity. For such applications, UV-stabilized PET sheets are recommended.
- Moisture & Chemicals: PET has good resistance to moisture and oils, but prolonged exposure to harsh chemicals may reduce its service life.
- High Temperatures: Standard PET performs well under normal conditions; for high-heat applications (e.g., ovens or microwaves), CPET is more suitable.
- Applications
- Food Packaging: Typically short-term use (days to weeks).
- Signage, Industrial Parts, Protective Covers: Multi-year service life when properly installed and maintained.
Summary: The lifespan of PET sheets is generally 5–10 years, with extended durability in indoor environments. For outdoor applications, UV-protected PET sheets are recommended to maintain long-term performance.
Are your PET sheets environmentally friendly?
- Recyclability
- Yes, PET sheets are among the most recyclable plastics.
- They carry the #1 recycling code (PETE), which is globally recognized and widely accepted in recycling streams.
- Advantages Over Other Plastics
- Unlike PVC or certain other polymers, PET does not release harmful chlorine compounds during recycling.
- Its lightweight and high strength help reduce raw material consumption and lower the carbon footprint.
- Food Contact Safety
- PET is safe and inert for direct food contact (Food Grade) and is approved by major regulatory bodies such as FDA and EFSA.
- Durability and Resource Efficiency
- With excellent clarity and strength, PET is an effective alternative to glass or PVC, helping reduce packaging waste and improving sustainability.
Summary: PET sheets are considered environmentally friendly due to their high recyclability, food safety, and lower environmental impact compared to other plastics—provided they are properly collected and recycled.
Are your PET sheets resistant to chemicals?
- General Resistance
- Yes, PET sheets show very good resistance to many common chemicals.
- They are stable against oils, fats, alcohols, and many diluted acids and bases.
- Limitations
- PET is not resistant to strong solvents such as acetone, toluene, or chloroform, which may cause clouding, swelling, or cracking.
- Prolonged exposure to strong alkalis (e.g., concentrated sodium or potassium hydroxide) can also damage the material.
- Service Conditions
- At room temperature, PET maintains excellent chemical resistance.
- At elevated temperatures (above 60–70 °C), resistance to some chemicals decreases.
- Safe Applications
- Thanks to this chemical stability, PET sheets are widely used in food, pharmaceutical, and hygiene packaging.
- They are also suitable for printing, displays, and protective applications, offering a reliable alternative to other plastics.
Summary: PET sheets are resistant to many chemicals such as diluted acids, bases, alcohols, oils, and fats, but are vulnerable to strong solvents and concentrated alkalis.
Can your PET sheets be used in wet conditions?
- Moisture Resistance
- Yes, PET sheets have excellent resistance to water and moisture.
- Their water absorption is very low (typically less than 0.5%), meaning they do not warp or lose mechanical strength even after prolonged exposure to humid environments.
- Performance Characteristics
- PET maintains its clarity and strength in wet conditions.
- Its smooth, non-porous surface prevents odor absorption and bacterial growth, which is why it is widely used in food and pharmaceutical packaging.
- Applications in Moist Environments
- Packaging for fresh food products (cheese, meat, vegetables).
- Protective covers and components exposed to steam or humidity.
- Trays and containers that can be washed and reused.
- Limitations
- Prolonged contact with hot water or high-temperature steam may cause loss of clarity or slight dimensional changes.
- For high-heat applications in wet environments, CPET (crystallized PET) is recommended.
Summary: Yes, PET sheets are well-suited for use in wet conditions thanks to their low water absorption and excellent moisture resistance. For applications involving hot water or steam, CPET is the preferred option.
How do I clean and maintain your PET sheets?
- Routine Cleaning
- For removing dust or light dirt, simply use a soft microfiber cloth.
- If needed, clean with lukewarm water and a mild detergent (such as diluted soap or dishwashing liquid).
- Washing Guidelines
- Avoid using abrasive materials (scouring pads, steel wool) as they may scratch the surface.
- Do not use strong solvents such as acetone, toluene, or gasoline, as these can cause clouding or surface cracks.
- Always rinse thoroughly with clean water to remove any detergent residues.
- Drying
- After cleaning, dry the sheet with a soft, lint-free cloth to prevent water spots or streaks.
- Storage and Maintenance
- Store PET sheets in a cool, dry environment, away from prolonged direct sunlight to maintain clarity.
- Avoid contact with sharp objects or heavy impacts.
- For warehouse storage, sheets should be kept flat or rolled on pallets to prevent warping or deformation.
Summary: To keep PET sheets in top condition, use mild cleaning agents and soft cloths, avoid solvents and abrasives, and store them properly in a cool, dry place away from sunlight for long-term durability and clarity.
