Pharmaceutical PVC/PE/PVDC Triplex Film for Blister Packaging
HSQY supplies pharmaceutical PVC/PE/PVDC triplex film for high-barrier thermoformed blister packaging of moisture- and oxygen-sensitive tablets, capsules, pills and other solid-dose products. The multilayer forming web combines the rigidity of pharmaceutical-grade PVC, the flexibility and forming support of PE, and the moisture, oxygen and aroma barrier of a PVDC coating.
Compared with plain PVC and standard PVC/PVDC duplex film, the PVC/PE/PVDC structure is designed for improved thermoforming, mechanical stability and deeper blister cavities while maintaining a transparent high-barrier package. Film structure, coating weight, roll width, color and barrier target can be customized according to the medicine, blister design and packaging machine.

Pharmaceutical PVC/PE/PVDC Triplex Blister Film
What Is PVC/PE/PVDC Pharmaceutical Blister Film?
PVC/PE/PVDC film, also called triplex pharmaceutical blister film, is a three-component thermoforming material. It is generally produced by laminating a pharmaceutical-grade rigid PVC base with a PE layer and applying a controlled PVDC barrier coating.
The PVC layer provides the main structural support and machine-running stability. The PE layer improves flexibility, impact performance and cavity formation. The PVDC layer reduces the transmission of water vapor, oxygen and aroma through the package. The resulting film is suitable for blister packs requiring more protection and more demanding forming performance than plain PVC.
Important naming correction: The industry-standard order is PVC/PE/PVDC because PE is laminated to the PVC base before the PVDC barrier coating is applied. “PVC/PVDC/PE” may appear in search queries, but the physical layer structure and quotation should be confirmed as PVC/PE/PVDC.

Key Benefits of PVC/PE/PVDC Blister Film
1. Configurable moisture barrier: The PVDC coating weight can be selected according to the medicine's water-vapor sensitivity and target shelf life.
2. Improved oxygen and aroma protection: The barrier coating helps reduce oxygen ingress and loss of volatile components compared with plain PVC.
3. Better deep-cavity formability: The PE layer improves flexibility and supports demanding blister shapes, larger cavities and higher draw ratios.
4. Mechanical stability: The triplex structure helps formed cavities withstand filling, sealing, cutting, cartoning and transport.
5. Transparent product visibility: Clear structures allow visual inspection of tablets and capsules while providing a higher barrier than standard PVC.
6. High-speed machine compatibility: Controlled friction, winding, width and forming properties support stable web transport when matched to the packaging line.
7. Custom structures and colors: PVC gauge, PE layer, PVDC coating, roll width, core, roll diameter, color and printing can be configured for the project.
Barrier Levels and Structure Selection
PVDC coating weight is an important purchasing parameter, but it should not be selected in isolation. Barrier performance also depends on coating chemistry, distribution, base-film gauge, package geometry, cavity surface area, environmental conditions and test method.
| Film Type |
Relative Barrier |
Typical Selection Logic |
| Plain PVC |
Standard / lower barrier |
Economical forming web for relatively stable products with lower moisture and oxygen sensitivity |
| PVC/PVDC duplex |
Medium to high barrier |
Common solution for sensitive tablets and capsules requiring improved protection without a PE intermediate layer |
| PVC/PE/PVDC triplex |
High configurable barrier |
Selected where improved barrier, impact strength, deep-draw formability and cavity stability are required |
| PCTFE laminate or cold-form foil |
Very high to near-total moisture barrier |
Considered for highly moisture-sensitive formulations when validated triplex PVDC performance is insufficient |
The final structure should be selected through stability studies and package testing. Provide HSQY with the target water-vapor transmission rate, oxygen-transmission rate, required shelf life, storage climate and blister dimensions whenever available.
Pharmaceutical Blister Packaging Applications

Frequently Asked Questions
What is PVC/PE/PVDC triplex film?
It is a three-component pharmaceutical thermoforming film made from a rigid PVC base, a flexible PE intermediate layer and a PVDC barrier coating. It is used for high-barrier blister packaging.
Is PVC/PVDC/PE the same as PVC/PE/PVDC?
The terms may be used interchangeably in online searches, but PVC/PE/PVDC is the clearer structural description: PVC is laminated with PE, and PVDC is then applied as the barrier coating.
Why is PE added between PVC and PVDC?
The PE layer improves flexibility, impact performance and thermoforming. It helps the film form deeper or larger cavities and improves the mechanical stability of the finished blister.
What does the PVDC coating weight mean?
PVDC coating weight is normally expressed in grams per square meter. Higher coating weights generally provide stronger barrier protection, but actual WVTR and OTR also depend on coating chemistry, package design and test conditions.
Which PVDC coating weights are commonly available?
Common triplex structures use PVDC coating weights such as 40, 60, 90, 100 or 120g/m². HSQY's actual available range should be confirmed against the required barrier and production schedule.
Is triplex film better than PVC/PVDC duplex film?
Triplex film is generally selected when the package requires improved deep-draw formability, impact strength and cavity stability in addition to PVDC barrier protection. Duplex film may remain more economical for shallower and less demanding blisters.
Can PVC/PE/PVDC film be used with PTP aluminum foil?
Yes. It is commonly used as the forming web with pharmaceutical push-through aluminum foil. The lidding lacquer, sealing side, temperature, pressure, dwell time and seal strength must be validated.
Is the film suitable for moisture-sensitive medicines?
It is designed for sensitive formulations requiring better moisture and oxygen protection than plain PVC. Final suitability must be demonstrated through stability studies and finished-package testing.
Can the film be used for deep-cavity blister packs?
Yes. The PE layer is specifically useful for larger or deeper cavities, but the achievable draw depends on the structure, mold, plug assistance, forming temperature and required minimum wall thickness.
Can HSQY supply colored or printed triplex film?
Clear, tinted and opaque colors can be discussed. Printing is also possible subject to ink compatibility, rub resistance, registration, surface orientation and pharmaceutical-packaging validation.
What roll information is needed for production?
Provide slit width, width tolerance, core diameter, maximum roll diameter, maximum roll weight, winding direction, coated-side orientation and acceptable number of joints.
Can I request a sample before placing a bulk order?
Available stock samples or trial rolls can be supplied for forming, sealing and preliminary barrier evaluation. The sample must match the intended PVC, PE and PVDC structure as closely as possible.
How do I get an accurate PVC/PE/PVDC film quotation?
Send the structure or target barrier, roll width, core, roll diameter, color, machine model, blister drawing, quantity, destination and required pharmaceutical documents.
