PET (Polyethylene Terephthalate) laminated aluminum foil is a commonly used type of laminated film packaging material.
The combination of PET and aluminum foil offers excellent barrier properties against moisture, oxygen, and other contaminants.
As a result, PET laminated aluminum foil is used in various applications, such as:
Heavy-Duty Packaging: The robust 70 μm laminated aluminum foil is a go-to choice for heavy-duty packaging applications. It serves as a formidable barrier layer, safeguarding contents from moisture, oxygen, light, and external factors. This foil is particularly suitable for packaging industrial products, large equipment, and bulky goods that require exceptional protection during storage and transportation.
Superior Insulation: With its substantial thickness, the 70 μm laminated aluminum foil excels as an insulation material in demanding environments. It offers unparalleled heat reflection and thermal insulation properties, making it an ideal choice for insulation boards, high-temperature HVAC systems, and industrial settings where excellent energy efficiency and insulation performance are required.
Electromagnetic Shielding Fortress: When it comes to shielding against electromagnetic interference (EMI) and radio frequency interference (RFI), the 70 μm laminated aluminum foil is a fortress. Its robust construction and ample thickness provide an impenetrable shield, effectively protecting sensitive electronic equipment, data centers, and communication systems from disruptive electromagnetic signals.
Brilliant Reflective Solutions: The 70 μm laminated aluminum foil creates brilliant reflective surfaces that go beyond mere functionality. From architectural design elements to high-end lighting fixtures, automotive accents, and solar energy systems, this foil's reflective properties add a touch of elegance, amplify light distribution, boost energy efficiency, and create captivating visual effects.
Heavy-Duty Thermal Management: When extreme heat management is paramount, the 70 μm laminated aluminum foil steps up. It stands as a heavyweight thermal barrier, reflecting and dissipating intense heat in industrial machinery, power generation systems, and high-performance automotive components. This foil ensures optimal thermal management, preventing heat-related damage and enhancing operational safety.
Robust Conductive Solutions: The 70 μm laminated aluminum foil serves as the backbone of robust conductive solutions in critical applications. From grounding systems in power plants and electrical grids to high-speed data transmission cables and aerospace electronics, this foil's generous thickness and exceptional conductivity guarantee reliable electrical contact, seamless grounding, and efficient electromagnetic shielding.
When considering the application of 70 μm laminated aluminum foil, it's essential to consult industry standards, regulatory guidelines, and manufacturer recommendations. Customization options, such as adhesive backing or surface treatments, may be available to address specific application requirements.
The following are some of the most important points to consider during the laminating process between PET film and aluminum foil:
1. Surface preparation:
It is essential to prepare the surfaces of both the PET film and the aluminum foil before lamination.
The surfaces should be clean, dry, and free from any dust or contaminants.
2. Adhesive selection:
The adhesive used for laminating PET film and aluminum foil should have good adhesion properties to both materials.
It should also be compatible with the type of printing or coating that will be used on the laminated material.
3. Temperature and pressure:
The laminating process should be carried out under controlled temperature and pressure conditions.
The temperature should be adjusted according to the melting point of the adhesive used, and the pressure
should be adjusted according to the thickness of the materials being laminated.
4. Roll tension:
The tension of the rolls used during lamination should be controlled to ensure that the materials are laminated
evenly and without wrinkles or distortions.
5. Handling and storage:
The laminated material should be handled and stored carefully to avoid any damage or contamination.
The material should be protected from moisture, temperature changes, and exposure to light.
6. Quality control:
A quality control process should be implemented to ensure that the laminated material meets the required specifications.
The material can be tested for its barrier properties, adhesion strength, and other parameters.
