Key Advantages

Exceptional Oxygen and Moisture Barrier

The EVOH core provides excellent oxygen barrier performance, helping reduce oxygen transmission and protect sensitive pharmaceuticals, nutraceuticals, diagnostic reagents, and specialty products from oxidation, moisture, spoilage, and potency loss.

Rigid and Durable Structure

The PVC outer layer offers stiffness, impact resistance, and stable thermoforming performance. It supports blister cavities, rigid trays, and medical packaging formats while reducing deformation during handling, transportation, and storage.

Reliable Heat-Sealing Performance

The LDPE inner layer provides strong sealing with aluminum foil, laminated films, and other packaging layers. It helps create leak-resistant seals for high-speed pharmaceutical and medical packaging lines.

Chemical Resistance and Safety

The composite sheet is designed for packaging environments involving pharmaceutical powders, coatings, diagnostic reagents, and medical materials. It offers stable performance and helps maintain packaging integrity during storage and distribution.

Customizable Specifications

Wallis can customize total thickness, layer ratio, roll width, pre-cut sheet size, color, opacity, surface finish, and printability according to medical packaging, pharmaceutical blister, and diagnostic packaging requirements.

Lightweight and Process-Friendly Packaging Material

Compared with some foil-based alternatives, PVC/EVOH/LDPE composite rigid sheets are lighter, easier to process, and suitable for thermoforming, sealing, printing, cutting, and packaging conversion.

Recommended Applications

Pharmaceutical Solid Dosage and Liquids

Suitable for tablets, capsules, soft gels, syrups, liquid reagents, and formulations requiring oxygen and moisture protection.

Biologics and Diagnostic Reagents

Ideal for proteins, enzymes, diagnostic kits, reagent packaging, and moisture-sensitive or oxidation-sensitive medical products.

Vitamins, Supplements and Nutraceuticals

Provides high-barrier protection for hygroscopic capsules, oxidation-prone ingredients, and long-shelf-life supplement packaging.

Medical Devices and Kits

Suitable for sterile instruments, medical kits, consumables, and rigid packaging formats that require mechanical strength and barrier protection.

High-End Food Packaging

Can be used for nuts, chocolates, specialty foods, and oxygen-sensitive products requiring protection against moisture, odor, and oxidation.

Export and Harsh Climate Packaging

Maintains packaging performance during long shipping routes, tropical climates, and variable temperature or humidity environments.

FAQ About PVC/EVOH/LDPE Composite Rigid Sheets

Is this material suitable for pharmaceutical and medical packaging?

Yes. PVC/EVOH/LDPE composite rigid sheets are designed for pharmaceutical, medical, diagnostic, and healthcare packaging applications that require high barrier performance and reliable sealing.

What is the role of EVOH in the composite sheet?

EVOH acts as the high-barrier core layer. It helps reduce oxygen transmission and protects sensitive products from oxidation, moisture-related degradation, and shelf-life reduction.

Can I request samples for testing?

Yes. Wallis can provide sample sheets or small rolls for evaluating barrier performance, heat-sealing strength, thermoforming behavior, thickness, color, and compatibility with your packaging line.

Can thickness, width, layer ratio, or color be customized?

Yes. Wallis supports customization of total thickness, layer composition, roll width, sheet size, color, opacity, surface finish, and packaging format according to customer requirements.

Is the sheet suitable for high-speed packaging lines?

Yes. The rigid sheet offers stable thickness, smooth surface quality, and good thermoforming performance for standard blister-forming, tray-forming, and heat-sealing equipment.

What applications are most suitable for PVC/EVOH/LDPE sheets?

Common applications include tablet blisters, capsule packaging, diagnostic reagent packaging, medical trays, supplement packaging, biologics packaging, and oxygen-sensitive specialty food packaging.
