Why choose PETG sheets for medical packaging?

Medical Industry Requirements

Medical packaging demands exceptional standards of hygiene, durability, and compliance with health regulations. Materials used for blister packs, trays, and sealing films must offer:

• Sterility and cleanliness
• Compatibility with gamma, EtO, or steam sterilization
• High impact resistance
• Visual clarity for easy product identification
• Non-toxicity and biocompatibility

In this demanding environment, PETG (Polyethylene Terephthalate Glycol) plastic sheets have emerged as a leading material due to their performance, reliability, and compliance.

PETG Material Overview

PETG is a thermoplastic polyester modified with glycol to enhance its toughness and clarity. As a rigid sheet material, it provides excellent thermoforming properties, making it ideal for deep-draw applications like medical packaging trays.

Key features:

• Thickness range: 0.18mm – 1.8mm
• High impact resistance (more than PVC or APET)
• Exceptional clarity
• Easy to sterilize
• 100% recyclable
• FDA-compliant and ISO standard compatible

At PULIXIN, we manufacture medical-grade PETG sheets in custom sizes and colors, including clear and blue variants, often used for surgical kits, pharmaceutical trays, and diagnostic device packaging.

Clarity and Sterilization Compatibility

One of the main reasons PETG is favored in medical packaging is its optical clarity, which ensures that the contents of blister packs or trays are fully visible — a crucial requirement in medical diagnostics and inventory management.

PETG is also resistant to whitening when bent or thermoformed, ensuring form integrity. More importantly, it withstands various sterilization methods:

This wide compatibility ensures that PETG packaging meets the needs of modern hospitals, labs, and pharmaceutical facilities.

Blister Packaging Examples

PETG sheets are widely used in thermoformed medical packaging such as:

• Surgical tool trays
• Injection device packaging
• Diagnostic test kits
• Dental kits
• Hospital sample containers

Their stiffness and formability make them ideal for deep-draw designs, while the material’s resistance to cracking ensures safe transportation and handling.

Regulatory Compliance

PETG sheets produced by PULIXIN meet the strict regulatory standards required for medical packaging:

• FDA 21 CFR 177.1315 for food and drug contact safety
• ISO 10993 for biocompatibility
• RoHS and REACH compliance

Additionally, our manufacturing process ensures clean-room-friendly production, minimizing contamination risks.

Why Choose PETG Over PVC

PETG and PVC are both used in medical packaging, but PETG offers several critical advantages:

In summary, PETG is safer, greener, and more versatile, making it the smarter long-term solution for medical packaging.

Conclusion

PETG plastic sheets provide a powerful combination of strength, clarity, and sterility for the medical industry. Whether used in blister packaging for surgical tools or custom trays for diagnostic kits, PETG meets the growing demands for safety, compliance, and sustainability.
