Amber PVC PE Film for Suppository Packaging
Product Desciption
1. Optimal Light Protection: The amber color of the PVC layer provides excellent protection against harmful UV rays and light exposure, making it ideal for light-sensitive liquids and substances. This feature helps preserve the integrity and quality of the packaged contents, ensuring they remain unaltered and unaffected by external factors.
2. Durable and Puncture-Resistant: The combination of PVC and PE results in a foil that is both robust and puncture-resistant. This durability provides reliable protection during handling, transportation, and storage, reducing the risk of leakage or product contamination.
3. Excellent Barrier Properties: The composite sheet's structure creates a superior barrier against moisture, gases, and other external contaminants, effectively extending the shelf life of the packaged products. It is particularly advantageous for liquids and suppositories that require airtight and secure packaging.
4. High Clarity and Visibility: Despite its amber hue, the PVC layer maintains a high level of clarity, allowing consumers to observe the contents of the packaging without compromising product visibility. This feature is particularly valuable in situations where product appearance is essential for consumer appeal.
Amber PVC PE Film for Suppository Packaging is a specialized blister packaging material designed specifically for suppository packaging – one of the most demanding pharmaceutical applications due to the unique physical and chemical characteristics of suppositories. The amber color provides essential UV protection for light-sensitive APIs, while the PE layer ensures secure sealing and compatibility with fatty/oily suppository bases (cocoa butter, Witepsol, etc.).
Why Suppository Packaging Is Different:
Suppositories contain fatty bases that melt at body temperature (34–37°C) – packaging must not absorb or interact with these lipids.
Many suppository APIs are light-sensitive (e.g., aminophylline, indomethacin, progesterone).
Suppositories are often large and heavy (1–3g each) – requiring strong, deep-draw cavities.
Production often involves low-temperature filling – film must withstand cold handling without becoming brittle.
Sealing must be secure – any leak causes the suppository base to weep (fatty bloom).
Structure:
PVC Layer: 200–300µm (rigid, thermoformable base)
PE Layer: 20–40µm (sealant, chemical barrier against fatty bases)
Amber Color: UV-blocking (transmission <5% at 400nm)
Total Thickness: 220–340µm (customizable)

Suppository-Specific Features
Deep Draw Capability – Can form cavities up to 14mm deep to accommodate large (3g) suppositories. Standard PVC/PE film often cracks at >10mm; our formulation uses higher molecular weight PVC with optimized plasticizer balance.
Low-Temperature Flexibility – Suppository filling often occurs at 5–10°C (to keep the base solidified). Our film remains flexible down to 5°C – no cracking or brittleness during cold handling.
Compatibility with Peelable Lidding – Available with peelable coating on PE layer for "easy-open" suppository blisters – critical for elderly and pediatric patients.
Anti-Static Option – PE layer can be treated with anti-static additive to prevent dust attraction during high-speed filling.
Print-Ready Outer Surface – PVC outer layer accepts high-quality printing – lot numbers, expiry dates, and brand logos remain legible after forming.
▸ Quality Assurance – Suppository-Specific Testing
In-Process Controls:
Thickness monitoring (beta gauge) – ±3% tolerance.
Amber color consistency – spectrophotometer (ΔE <2).
PE coat weight – XRF (target ±2 µm).

Feature
2. Perfect flexibility, low damage in transport;
3. Good sealing;
4. Good oxygen and water vapor barrier and it can prevent the content go bad or invalid and can extend the shelf life twice
longers.
The PVC/PE foil provides an excellent barrier against moisture. For liquid packing, it prevents water vapor from permeating through the packaging and spoiling the liquid contents. For example, in the case of aqueous solutions such as syrups or certain pharmaceutical liquids, this property helps maintain the liquid's concentration and stability. In suppository packing, it safeguards the suppositories from humidity, ensuring that they do not become soft or lose their shape due to moisture absorption.
Applications – What Type of Suppositories Use This Film?

PVC/PE foil offers good printability. It allows for clear and vivid printing of product information such as brand names, ingredients, usage instructions, and expiry dates. The surface of the foil can be treated to enhance ink adhesion, enabling high - resolution printing. This is crucial for both liquid and suppository packaging to provide consumers with accurate and necessary details about the product.
FAQ
Q1: Why can't I just use clear PVC/PE for suppositories?
Clear film does not provide UV protection. Many suppository APIs degrade under light (even pharmacy fluorescent lighting). Amber is the minimum standard for light-sensitive suppositories.
Q2: Does the PE layer affect the release of the suppository from the blister?
No – the PE layer is on the inner surface (contacting the suppository). Its smooth, non-stick surface ensures the suppository releases cleanly – no sticking or tearing.
Q3: What about suppositories with oily bases – does the film absorb oil?
No – PE is highly oil-resistant. The film does not absorb cocoa butter or other lipid bases. We test for weight gain after 30 days of contact – <0.5% (negligible).
Q4: Can I store this film in the refrigerator (cold storage)?
Yes – it remains flexible down to 5°C. Below 0°C, we recommend conditioning at room temperature for 24 hours before use to prevent moisture condensation.
Q5: Is this film suitable for "cold filling" (suppositories filled at 5–10°C)?
Yes – the film retains flexibility at low temperatures. No cracking or brittleness. We test at 5°C before release.
Q6: Can I get the film without PE (just amber PVC) for lower cost?
Yes – we offer Amber PVC only. However, without PE, the seal strength may be lower, and there is a higher risk of plasticizer migration into the suppository base. We recommend PE for all suppository applications.
Q7: What is the shelf life of the film itself?
24 months when stored at 15–25°C, <60% RH, away from direct light. Amber color remains stable for 36 months (tested).
