What is pet laminated film made of?
PET laminated film
is made of polyethylene terephthalate (PET) and a layer of adhesive that is used to bond the film to another substrate. PET is a type of thermoplastic polymer that is commonly used for packaging due to its high tensile strength, durability, and ability to resist moisture and chemicals. The adhesive layer can be made of a variety of materials, such as acrylic or polyurethane, and is used to bond the PET film to other materials, such as paper or aluminum foil, to create a laminated film with specific properties. The composition of the PET laminated film can vary depending on its intended application and the specific properties required.
What are the benefits of using pet laminated film?
PET laminated film offers several benefits, including:
Barrier properties: PET laminated film provides a barrier against moisture, oxygen, and other gases, which helps to preserve the quality and freshness of the packaged product.
Strength and durability: PET is a strong and durable material that can withstand rough handling, punctures, and tears, making it ideal for packaging products that need to be transported long distances.
Transparency: PET laminated film is transparent, which allows the packaged product to be visible and can enhance the product's appearance on store shelves.
Printability: PET laminated film can be printed with high-quality graphics, text, and branding, which can help to promote the product and improve its marketability.
Recyclability: PET is a recyclable material, which means that PET laminated film
can be recycled and reused, reducing its environmental impact.
Cost-effective: PET laminated film is cost-effective compared to other packaging materials, such as glass or metal, making it a popular choice for a variety of applications.
Overall, PET laminated film offers a combination of barrier properties, strength, transparency, and printability, making it a versatile packaging material that is suitable for a wide range of products.
How is pet laminated film produced?
PET laminated film is produced through a process known as lamination, which involves bonding a layer of PET film to another substrate using an adhesive.
The production process typically involves the following steps:
Coating: The adhesive is coated onto the PET film using a coating machine.
Lamination: The coated PET film is then bonded to the desired substrate, such as paper or aluminum foil, using a laminating machine. The two materials are passed through a set of heated rollers that apply pressure to ensure a strong bond.
Slitting: The laminated film is then slit into the desired width and length using a slitting machine.
Finishing: The finished laminated film may undergo additional finishing processes, such as corona treatment to improve its printability or embossing to create a textured surface.
The exact process and equipment used may vary depending on the specific application and the requirements of the customer. PET laminated film can be produced in a range of thicknesses and with different adhesive formulations to meet specific performance requirements.
