40 μm PET laminated aluminum foilm, excellent barrier properties, used for food packaging, pharmaceuticals and cosmetic
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:
1. Food packaging:
PET laminated aluminum foil is used for packaging food products such as snacks, coffee, tea, and spices.
The material provides good protection against moisture, light, and oxygen, which can help to extend the shelf life of the food products.
2. Pharmaceuticals:
PET laminated aluminum foil is used for packaging of pharmaceutical products such as tablets, capsules, and other solid dosage forms.
The material provides good protection against light, moisture, and oxygen, which can help to increase the effectiveness and shelf life of the drugs.
3. Cosmetics:
PET laminated aluminum foil is used for packaging of cosmetics products such as powders, creams, and lotions.
The material provides good protection against light, moisture, and oxygen, which can help to preserve the quality and
effectiveness of the cosmetics.
4. Industrial applications:
PET laminated aluminum foil is used for various industrial applications such as insulation and packaging of electronic devices.
The material provides good protection against moisture, light, and oxygen, which can help to extend the longevity of the product.
In summary, PET laminated aluminum foil is a versatile and widely used packaging material that provides good barrier properties against moisture, oxygen, and other contaminants. It is used in various industries ranging from food packaging to pharmaceuticals to industrial applications.
The biggest consumable application for PET laminated aluminum foil is in the food packaging industry.

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.
