60-micron transparent PVC aluminum foil film
60-micron transparent PVC cold-formed aluminum foil film is a crucial packaging material for the pharmaceutical industry.
In the pharmaceutical packaging industry, "cold-formed aluminum foil laminated with transparent PVC film" sounds technical but is crucial. From small antibiotic capsules to large freeze-dried preparations, highly sensitive pharmaceuticals that require protection from oxygen, moisture, and light rely on this composite film for long-term freshness preservation. It seamlessly combines the superior barrier properties of aluminum foil with the transparency and cold-formability of PVC film, providing both a safety barrier for pharmaceuticals and an efficiency boost for production. Today, we'll take a look at this composite film and see how it provides a multi-layered defense for pharmaceutical packaging.
First, let's understand: What exactly is cold-formed aluminum foil laminated with transparent PVC film?
This composite film is not a single material, but rather a multi-layer structure formed by bonding cold-formed aluminum foil and transparent PVC film (often with an added layer of OPA oriented polyamide film for added strength) through a dry lamination process. The core design is centered around the two key requirements of "cold forming" and "high barrier," with each layer playing a crucial role.
Thickness: 60 microns (0.06 mm). This thickness ensures the PVC film possesses appropriate mechanical strength and flexibility.
Color and Clarity: Typically transparent, with high gloss and clarity, allowing for easy viewing of the packaged product.
Material Composition: Primarily made of PVC (polyvinyl chloride), it exhibits excellent chemical stability and physical properties.
Performance Characteristics: Barrier Properties: It offers excellent barrier properties against moisture, oxygen, and light. When combined with aluminum foil, it forms a complete barrier layer, preventing external factors from affecting pharmaceutical quality, making it particularly suitable for packaging highly sensitive medications.
Mechanical Properties: The film exhibits high tensile strength, low shrinkage, and excellent flexural and chemical resistance. These properties ensure that the packaging is not easily damaged during handling, transportation, and storage, thereby protecting pharmaceutical products.
Thermoformability: It exhibits excellent thermoformability and can be easily formed into various shapes on standard blister packaging machines, facilitating the production of diverse pharmaceutical blister packaging shapes. It also has excellent heat-sealing properties and can be heat-sealed effectively with rigid aluminum foil, ensuring a secure, airtight package.
Applications in Aluminum Foil Packaging
In aluminum foil construction, 60-micron transparent PVC film is typically combined with oriented polyamide (OPA) and aluminum foil. A typical aluminum foil composition includes 25-micron OPA film, 45-60-micron aluminum soft foil, and 60-micron PVC film. The PVC film is a crucial component of the multilayer structure, not only enhancing the foil's overall mechanical strength but also playing a significant role in its barrier and heat-sealing properties.
