Pharmaceutical aluminum blister foil: barrier, coating and line fit
Aluminum lidding combines an opaque foil layer with a printable surface and a heat-seal coating. Match the coating to the surface it will actually seal against, whether the pack uses a thermoformed web or a cold-form base. Barrier performance depends on the complete pack, including pinholes, cavity formation and seal integrity. Custom widths and print specifications are confirmed for the selected roll construction.
Sample checks before bulk approval
Use sample rolls with the intended forming web and machine settings. Record sealing temperature, pressure, dwell time, line speed and opening behavior, then compare results against the agreed seal and leak-test criteria. Confirm roll dimensions, print registration, batch identification and packing before approving the production specification.

Where pharmaceutical aluminum blister foil is used
Pharmaceutical aluminum blister foil is widely used as the lid of unit-dose tablet and capsule packs. The aluminum layer provides a barrier on the lidding side; the forming web, seal and finished pack must also suit the medicine. The application examples below identify questions to resolve during sourcing, not approvals for every formulation in a drug class. For regulatory context, the FDA container-closure guidance addresses packaging suitability, while WHO GMP guidance concerns manufacturing practices. Neither is a product-specific Qixin certificate.
Antibiotics & Prescription Tablets
For moisture-sensitive antibiotic or prescription-tablet projects, compare the lidding foil together with the forming web and seal design. Include the formulation’s sensitivity, destination storage conditions and transport route in the enquiry. A two- or three-year target belongs in the finished-drug stability plan; it is not a shelf life assigned by a 20 or 25 micron foil thickness. Qualify the seal on the intended line and assess the medicine in its final packaging. ICH Q1B concerns photostability, not a heat-seal integrity test method.
Cardiac & Hormone Medications
For a light-sensitive cardiac or hormone product, opaque aluminum lidding helps shield the lidding side of the pack. A transparent forming web can still admit light, so review the entire pack and any carton with the formulation team. Specify print artwork, batch-code areas and the opening method separately. Custom print and a visibly opened cavity can aid identification and pack inspection; they do not by themselves establish tamper-evidence, child-resistance or regulatory acceptance.
Vitamins & Nutraceuticals
For vitamins, soft capsules or probiotic tablets, start with the product’s actual sensitivity to moisture, oxygen and light. The choice of lidding, forming web and secondary packaging can differ between formulations. Send the declared storage conditions, target shelf life and existing pack specification when requesting a comparable foil. Confirm print legibility and opening behavior during the sample trial, and use finished-product stability results to support potency claims at expiry.
Tropical & Humid Climate Export
For hot or humid export routes, specify the conditions to be evaluated and review both sides of the blister. A thicker lid alone does not qualify a pack for a climatic zone. When comparing WVTR results, use the same method, temperature, humidity, specimen construction and units, and distinguish flat-film results from finished-pack results. Ask for the report’s detection limit before interpreting a result described as zero. Select the final combination using the drug product’s stability program and market requirements.
Generic Drug Manufacturing
Generic-drug manufacturers need a defined foil specification and a traceable supply, not just a material name. Agree the alloy and temper, nominal gauge and tolerance, coating identification, print requirements and batch-release checks. Specify which tests belong on each batch CoA and which require a separate qualification report. If a submission needs a Drug Master File, confirm the applicable filing route, holder, reference and authorization arrangements before relying on it. A generic certificate or a report for another foil does not establish dossier coverage.
Private Label & Contract Packaging
Contract packers and private-label buyers can specify roll formats and artwork for their blister equipment. The listed width range for QX-BLISTER-FOIL is 60-700mm; confirm the exact slit width, tolerance, core diameter, outside diameter, winding direction and print repeat for the order. Separate preprinted artwork from variable batch or expiry coding on your line. Minimum order quantity, sample arrangements and lead time are discussed at enquiry stage against the selected construction and print requirements.
Technical specifications: lidding gauges and cold-form base distinction
QX-BLISTER-FOIL lists 0.018-0.036mm thickness, 60-700mm width, 8011/8079 alloy options and an OP/Printing/AL/VC lacquer structure. These are enquiry options, not a release specification for every order. The 20 and 25 micron examples below are lidding gauges within that range. OPA/AL/PVC is a separate cold-forming base construction shown for comparison, not an interchangeable lid or a confirmed variant of this SKU. Confirm whether a quoted thickness describes the aluminum layer or the finished coated material.

|---|---|---|---|
| Thickness basis | 20 micron; confirm basis | 25 micron; confirm basis | Specify each layer and total |

From an existing production run to a comparable foil sample
Your working specification and line experience are useful starting points. Send the foil and forming-web grades together with the operating conditions and observed result. This helps distinguish a material change from a sealing, winding or registration issue, and makes a repeat trial easier to compare.
- Material: alloy and temper, aluminum gauge, total coated thickness, lacquer identification and forming-web seal surface.
- Machine: sealing temperature, pressure, dwell time or line speed, tooling and the production date or trial reference.
- Result: seal-strength or leak-test method, acceptance limit, sample count and observed failures or passes. Keep visual observations separate from measured results.
- Artwork and winding: print repeat, eye marks, unwind direction, splice limits, core and roll drawing.
- Stability: intended storage conditions and target shelf life. If the target is two or three years, identify whether supporting data are planned, interim or completed for the finished drug pack.
Quality documents and pharmaceutical packaging background
The Qixin company profile describes the business’s origins in pharmaceutical packaging. An archived Chinese pharmaceutical-packaging registration names Zibo Hengzhou Aluminium-Plastic Packaging Materials Co., Ltd. and pharmaceutical aluminum foil at 0.024mm. The displayed document was valid until 19 June 2021. It is historical product documentation, not a current GMP certificate or a blanket approval for every foil specification.
For supplier qualification, request current records matching the manufacturing entity, site and quoted construction. Separate quality-system certification, material registration, sample test reports and batch CoAs. Confirm which tests and limits will be reported for the order; an archived food-contact test is not a test of every pharmaceutical application.
For technical review, ICH Q1A(R2) addresses stability in the proposed container-closure system, while ICH Q1B addresses photostability. Neither assigns a universal shelf life to a foil gauge. The medicine manufacturer’s quality and regulatory teams determine the applicable qualification program.
Pharmaceutical Aluminum Blister Foil questions
Which medicines can use pharmaceutical aluminum blister foil?
Tablet and capsule projects may use aluminum lidding where the complete blister suits the formulation. Discuss moisture, oxygen and light sensitivity, the forming web and the desired opening method. A drug class or export destination alone does not prescribe one foil gauge. The medicine manufacturer establishes the final pack’s suitability for the intended market and shelf life.
What is the difference between 20 and 25 micron pharmaceutical foil?
Both are lidding gauge options. Compare opening force, foil handling, print and coating requirements using sample rolls on the intended machine. Higher nominal thickness does not guarantee freedom from pinholes, a tropical-climate approval or a longer drug shelf life. Agree thickness tolerance and inspection criteria, and assess the finished pack rather than selecting by climate label alone.
What heat-sealing temperature is required?
Use the temperature window for the agreed lacquer and forming-web combination. If your existing PVC process runs at 150-180°C, or a PVDC process at 160-190°C, include that experience with the coating grade, pressure, dwell time and line speed in the sample request. These are conditional examples, not universal settings or a validated Qixin process window. Arrange sample rolls and verify the seal before bulk production. Cold forming describes cavity formation without heating the base; the finished blister still requires a separate lidding-seal operation.
Which regulatory documents should accompany a pharmaceutical foil enquiry?
State the destination market, foil construction and intended drug-contact use. Request the applicable registration or filing information, current site or quality-system certificates, an agreed CoA format and relevant test reports. Check that each document covers the supplier, material and test scope you need. Where a DMF is required, confirm its holder, reference and access authorization; do not assume that a general website document establishes a filing for your order.
Is pharmaceutical aluminum foil safe for direct drug contact?
Assess the full material construction, including the coating or laminate surface that may contact the medicine. Compatibility depends on the formulation and intended storage conditions. Agree the applicable chemical, migration or extractables/leachables assessment with the buyer’s quality team. A general aluminum description or food-contact report does not replace drug-packaging suitability evidence for the selected construction.
What roll widths and core sizes are available?
The listed enquiry range is 60-700mm in width. Provide the machine’s actual slit-width tolerance, core inside diameter, maximum roll outside diameter, roll weight and winding direction. If your line uses a 76mm or 152mm core, specify the exact dimensional requirement rather than relying only on a nominal 3-inch or 6-inch name. Confirm the final roll drawing and packing arrangement before ordering.
Aluminum lidding and blister forming-web selection
The materials below play different roles: aluminum foil is shown as lidding, while plain PVC and PVDC-coated PVC are forming-web options. They are not direct substitutes for every layer of a blister. Use the comparison to define what the full package needs, then compare supplier reports under matching conditions. For packaging qualification, see the FDA container-closure guidance.
| Feature | Aluminum Lidding (20-25 micron) | Plain PVC Forming Web | PVDC-coated PVC Forming Web |
|---|---|---|---|
| Moisture barrier (WVTR) | Check foil and seal integrity | Specify thickness and test conditions | Specify coating grade and test conditions |
| Light barrier | Opaque on the lidding side | Typically transparent; assess full pack | Typically transparent; assess full pack |
| Hot/humid market use | Validate the whole blister | Validate the whole blister | Validate the whole blister |
| Opening behavior | Specify push-through or other route | Depends on the matched lid | Depends on the matched lid |
