HSQY Pharmaceutical PTP Aluminum Blister Lidding Foil

PTP Aluminum Blister Lidding Foil for Pharmaceutical Packaging

HSQY PTP aluminum blister lidding foil is designed for pharmaceutical blister packaging of tablets, capsules and other solid-dose products. The aluminum layer provides strong protection against moisture, oxygen and light, while the heat-sealable surface allows the foil to be bonded to compatible blister forming materials.

The foil is designed for press-through blister packaging, allowing the tablet or capsule to be pushed through the lidding foil when opened. Printed and customized options can be discussed for pharmaceutical branding, product identification, dosage information and other approved packaging artwork.

HSQY currently supplies PTP aluminum foil in thicknesses from 0.020mm to 0.024mm, widths up to 650mm and roll diameters up to 500mm. Final foil structure, heat-seal coating, printing, reel dimensions and compatibility should be confirmed according to the customer's blister substrate and packaging machine.

What Is PTP Aluminum Blister Lidding Foil?

PTP stands for Press Through Pack. PTP aluminum foil is the lidding material sealed over formed pharmaceutical blister cavities containing individual tablets, capsules or other solid-dose products.

During packaging, the blister base material is first thermoformed into cavities, the medicine is loaded into each cavity, and the aluminum lidding foil is then heat sealed over the blister web. The finished pack provides individual-dose protection while allowing the user to push the medicine through the foil when required.

PTP foil is commonly used with pharmaceutical blister base materials such as PVC, PVDC-coated PVC, PP and other validated thermoforming structures. Compatibility depends on the heat-seal lacquer formulation and sealing conditions, so the exact blister base material should always be specified before ordering.

PTP Aluminum Lidding Foil Specifications

The following values are based on the current HSQY product information. Pharmaceutical packaging buyers should confirm the complete approved specification, coating, reel format and test requirements before commercial production.

Typical Structure of PTP Blister Lidding Foil

Pharmaceutical PTP foil is normally engineered as a coated aluminum lidding structure rather than bare aluminum alone. The exact HSQY coating system should be confirmed against the approved product specification.

Typical Unprinted Structure

A typical unprinted pharmaceutical blister foil structure uses a printable primer or protective coating on the outer side, aluminum foil as the central barrier layer and a heat-seal lacquer on the blister-sealing side.

Typical industry description: Primer / Aluminum / Heat-Seal Lacquer.

Typical Printed Structure

Printed PTP foil normally includes an outer protective coating, printing ink, aluminum barrier layer and heat-seal lacquer.

Typical industry description: Over Lacquer / Ink / Aluminum / Heat-Seal Lacquer.

The exact coating chemistry, coating weight, ink system and sealing surface should be specified according to the pharmaceutical packaging application and blister base material.

Key Advantages of PTP Aluminum Blister Foil

High Barrier Protection: Aluminum foil provides strong protection against moisture, oxygen and light, helping isolate individual solid-dose products from external environmental exposure.

Press-Through Opening: PTP foil is designed so tablets and capsules can be pushed through the lidding layer during use, providing convenient unit-dose access.

Heat-Sealable Surface: A suitable heat-seal coating allows the aluminum foil to bond to compatible pharmaceutical blister forming materials under controlled temperature, pressure and dwell time.

High-Quality Printing: Printed foil can carry medicine names, logos, dosage instructions, batch information, expiry information and other approved packaging content.

Unit-Dose Protection: Each blister cavity remains individually sealed until opened, supporting organized pharmaceutical dispensing and handling.

Roll Format for Automated Packaging: PTP foil is supplied in reels for pharmaceutical blister packaging equipment. Width, roll diameter and winding requirements should be matched to the customer's machine.

Custom Specifications: Foil width, printing and reel specifications can be discussed according to blister line requirements and purchasing volume.

PTP Aluminum Foil Compatible Blister Materials

Heat-seal compatibility depends on the lacquer system used on the aluminum foil. The exact forming film must therefore be stated when requesting a quotation or sample.

How to Choose PTP Aluminum Blister Foil

1. Confirm the Aluminum Foil Thickness

HSQY currently lists a foil thickness range of 0.020mm to 0.024mm. Thickness affects push-through characteristics, handling and machine performance, so the required gauge should be matched to the validated blister specification.

2. Specify the Blister Base Material

State whether the foil will seal to PVC, PVDC-coated PVC, PP, PET or another blister-forming material. The heat-seal lacquer must be compatible with the substrate.

3. Confirm Printed or Unprinted Foil

For printed foil, provide approved artwork, colors, text direction, repeat length, registration requirements and any coding area that must remain available for later printing.

4. Confirm Reel Dimensions

Provide required web width, core inner diameter, maximum reel outer diameter, winding direction and preferred roll weight. HSQY currently lists widths up to 650mm and roll diameters up to 500mm.

5. Confirm Heat-Seal Requirements

Provide the existing sealing temperature, pressure, dwell time and required seal strength if available. These values help determine whether the heat-seal coating matches the packaging line.

6. Confirm Push-Through Performance

The finished lidding foil should balance package integrity during handling with appropriate push-through opening for the intended blister design. The final result should be validated using the actual foil, blister substrate and medicine pack configuration.

7. Confirm Regulatory and Quality Documentation

Pharmaceutical packaging requirements differ by market and customer. Provide the exact pharmacopoeial, regulatory, migration, raw-material, coating or quality-document requirements so HSQY can confirm what documentation is available for the specific product supplied.
