80 Micron Natural Color Cast Polypropylene Film Retort Cpp Film High Puncture

Product Specification

80 μm natural color cast polypropylene film for food, medical can industrial packaging

80-micron natural color cast polypropylene (CPP) film is a relatively thick film that offers excellent durability

and performance in many different applications. Its main uses include:

1. Food packaging:

    With its high puncture resistance, strong seal strength, and excellent barrier properties, 80-micron natural color CPP film is ideal

    for packaging food products such as meat, cheese, and snacks. The film's thickness also makes it suitable for vacuum packaging.

2. Industrial packaging:

    80-micron natural color CPP film is used extensively in industrial packaging applications, such as wrapping heavy-duty products,

    bundling, and pallet wrapping. Its strength and puncture resistance offer superior protection during transportation and storage.

3. Medical and pharmaceutical packaging:

    The high-performance properties of 80-micron natural color CPP film make it an ideal choice for packaging medical devices, surgical

    instruments, and other medical products. Its thickness ensures that the package contents are protected during shipping and storage.

4. Stationery and gift packaging:

    80-micron CPP film is often used in stationery and gift packaging, such as folders, portfolios, and gift boxes.

    The film's thickness ensures that the packaging is sturdy and that the products inside are adequately protected.

5. Labeling:

    80-micron natural color CPP film is also used for labeling applications, where the thickness ensures that the label adheres well to the

    packaging surface and is durable over time.

6. Lamination:

    80-micron natural color CPP film can also be used as a bonding layer in laminated structures with other films or papers to provide

    added strength, durability, and barrier properties.

Overall, the thickness and performance properties of 80-micron natural color CPP film make it a versatile and popular packaging material that

can be used in many different industries. Its suitability for different temperature ranges and resistance to environmental factors like moisture

and chemicals, makes it an excellent choice for packaging a wide variety of products.

 
The significant feature of cast polypropylene film is its excellent transparency, high gloss, and good moisture barriers making it suitable for packaging applications where product visibility is important. It is also highly durable, flexible, and has excellent sealing properties, making it

ideal for applications requiring heat sealing. Furthermore, CPP film is highly resistant to punctures, tearing, and abrasion, which makes it a

reliable option for packaging applications that face rough handling during transportation.

Additionally, CPP film has good stiffness and dimensional stability, which means it is unlikely to shrink or stretch during processing or use, which

can help to ensure consistent packaging performance. It has also good printability and great clarity of graphics, which makes it ideal for using

visual cues as branding elements on packaging.
 
The process for producing cast polypropylene (CPP) film involves:
 
1. Polymerization:
    Propylene monomers are polymerized under pressure and high temperature to produce polypropylene resin pellets.
 
2. Extrusion:
    The polypropylene resin pellets are melted and extruded through a flat die to form a thin, continuous sheet.
3. Orientation:
    The extruded sheet is stretched across the machine direction (MD) and transverse direction (TD) to improve the mechanical
    properties and clarity of the film.
 
4. Cooling:
    The film is cooled down using a cooling roll and stored on a take-up roll.
 
5. Finishing:
    The film is treated with corona discharge or other surface treatments to improve printing quality and adhesion.
 
Now, coming to the advantages of CPP film over Biaxially Oriented Polypropylene (BOPP) film:
 
1. Improved sealing properties:
    CPP film has better sealing properties due to its higher seal strength, which makes it ideal for use in food packaging applications.
 
2. Enhanced clarity:
    CPP film has better clarity and gloss than BOPP film, which makes it more attractive for use in packaging applications where product
    visibility is essential.
 
3. Better hot tack properties:
    CPP film has better hot tack properties, which allows it to be used in high-speed packaging machines where quick sealing is required.
 
4. Increased heat resistance:
    CPP films have greater heat resistance than BOPP films, making them better suited for use in hot-fill and retort packaging applications
    where high temperatures are required.
 
5. Higher puncture resistance:
    CPP films have higher puncture resistance than BOPP films, making them more durable and resistant to damage during transportation
    and storage.
 
Overall, CPP film has several advantages over BOPP film, making it a popular choice for a wide range of packaging applications. CPP films' improved sealing properties, clarity, heat resistance, and puncture resistance make them ideal for use in food packaging, as well as in industrial and agricultural packaging applications.
