Pharmaceutical PET/PE Composite Hard Sheet – High-Barrier Packaging

Shanghai Wallis Technology Co., Ltd. presents our upgraded PET/PE composite hard sheet, now enhanced with an EVOH barrier layer for pharmaceutical liquid packaging. This advanced material provides exceptional oxygen and moisture protection, chemical stability, and reliable heat-seal performance, ensuring the integrity and shelf life of sensitive medicines, reagents, and biologics.

PET/PE——Liquid Sealing Material

PET/PE liquid sealing material is a composite rigid sheet specially designed for pharmaceutical liquid packaging. It is made of pharmaceutical-grade PET (polyethylene terephthalate) as the base material through precision processes such as coating and lamination. It combines the core advantages of PET and PE (polyethylene) and is widely used in the field of pharmaceutical packaging.

Advantages of the PE PET Pharmaceutical Tablet Packaging

Superior Barrier Performance

The EVOH layer drastically reduces oxygen and moisture transmission, protecting sensitive pharmaceuticals from oxidation and degradation. This ensures longer shelf life and maintains drug potency.

Reliable Heat-Seal Performance

The inner PE layer provides strong, consistent seals compatible with standard pharmaceutical filling and sealing equipment. It prevents leaks during sterilization and transport.

Chemical and Physical Stability

PET/EVOH/PE combination resists acids, bases, and solvents, making it compatible with a wide range of liquid APIs, herbal extracts, and reagents. It maintains structural integrity under varying storage conditions.

Customization Flexibility

Thickness, width, color, and opacity can be tailored to client requirements. Tinted or opaque versions protect light-sensitive liquids. Surface printability allows batch numbers, drug names, and logos.

Sustainability and Compliance

Lightweight and partially recyclable, it is a safer alternative to metal or foil laminates. Complies with pharmaceutical packaging standards and supports sterilization processes.

Recommended Applications

Injectable solutions and sterile reagents:

Ensures product stability during transport and storage.

Biologics and diagnostic reagents: 

Maintains sensitive biomolecules without degradation.

Vitamin or antioxidant solutions: 

Protects compounds from oxidation.

Herbal and botanical liquid extracts: 

Preserves active ingredients against environmental factors.

Light-sensitive or oxygen-sensitive pharmaceutical liquids: 

Customized tinted or opaque sheets shield from light exposure.

Laboratory and chemical reagents: 

Compatible with aggressive chemicals, maintaining container integrity.

This sheet is suitable for both pre-formed pouch packaging and rigid sheet forming/thermoforming processes, offering versatility for various pharmaceutical production lines.

Why Choose WALLIS PE/PET High-Barrier Rolls?

Outstanding Oxygen & Moisture Barrier

The PE/PET coating significantly reduces oxygen transmission rate (OTR) and water vapor transmission rate (WVTR), keeping pharmaceuticals protected from humidity, oxidation, and active ingredient degradation.

Excellent Chemical Stability

The sheet maintains its integrity and barrier function when in contact with pharmaceutical powders, coatings, and moisture-sensitive formulations. No harmful migration and fully compliant with packaging safety requirements.

Strong Mechanical Strength

It offers superior thermoforming performance, allowing deep-draw blister shapes without cracks, whitening, or stress marks. Heat-sealing strength is high and suitable for high-speed automatic packaging lines.
