80 Micron Translucent Red Cast PP Film Personal Care Packaging

Product Specification

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

80-micron translucent red or opaque red cast polypropylene (CPP) film is a sturdy, high-quality, and durable packaging material that is used

mainly in heavy-duty industrial and commercial applications where a thicker film is required. Here are some of the primary uses of 80-micron

translucent red or opaque red CPP film:

1. Industrial and Heavy-Duty Packaging:

    The thicker 80-micron film is therefore suitable for packaging heavy-duty goods like machine parts, construction equipment, and other

    industrial items that need to be transported over long distances without any possible damage.

2. Retail Packaging:

    The red color and outstanding translucency of the film make it ideal for the retail industry as it provides a visual display of the goods,

    making it convenient for the customer to access their desired product easily.

3. Shipping and Mailing:

    80-micron CPP film is commonly used to package products for shipping, mailing, or storage. Its high strength and puncture resistance

    ensure that the products will reach their destination in good condition.

4. Impulse Sealing Applications:

    80-micron translucent red or opaque red cast polypropylene films are suitable for bags, pouches, and other packaging formats that require

    excellent heat-sealing properties and tear resistance.

5. Stationery Packaging:

    The thicker 80-micron film is suitable for packaging school and office supplies such as books, pencils, and other stationery items,

    which require additional protection from environmental damage or moisture.

6. Personal Care Packaging:

    The film's high moisture barrier properties make it an ideal choice for packaging personal care products like shampoo, conditioner, and lotion.

Overall, 80-micron translucent red or opaque red cast polypropylene film is a heavy-duty and durable packaging material, ideal for use in

commercial and industrial applications. Its strength and puncture resistance make it desirable for packaging heavy-duty items, while the red color

and translucency make it ideal for retail display and impulse sealing applications.

 
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. 

There are various ways to improve the mechanical properties of cast polypropylene (CPP) film and to enhance its functionality.

Here are some of them:

1. Additives:

    Adding certain additives to the CPP film can significantly improve its performance properties. For example, adding slip agents to CPP film

    can reduce friction and enhance its slip properties. Similarly, adding anti-block agents can help to reduce blocking and improve film clarity.

2. Blending:

    Mixing polypropylene with other polymers or fillers can improve film properties such as puncture resistance, tear strength, and stiffness.

    For example, blending polypropylene with polyethylene or thermoplastic elastomers (TPE) can provide a balance of stiffness and flexibility.

3. Coating or laminating:

    Coating or laminating the CPP film with other materials can help to enhance its barrier properties or surface properties such as printability.

    For example, coating the film with metal or oxide layers can improve its barrier properties, while laminating it with another polymer can improve

    its printability or add other properties.

4. Nano-composite materials:

    Incorporating high-performance nano-composite materials into CPP films can improve their mechanical properties and enhance their

    functionality. For example, adding graphene or carbon nanotubes to CPP film can provide high tensile strength and conductivity.

5. Film orientation:

    Stretched or oriented CPP films are stronger and more resistant to punctures and tearing than non-stretched films.

    Orientation can be done mechanically, such as by stretching the film in two directions or by adding a biaxial stretching process, or by adding

    some treatments like Corona treatment.

Overall, the methods to increase the mechanical properties or other functions of CPP films involve the addition of additives, blending, coating, laminating, and orientation. Tailoring the film's formulation and processing conditions can achieve the desired properties and functionality in the CPP film.
