50 μM Red Cast Polypropylene Film For Food, Medical Can Industrial Packaging

Product Specification

50 micron translucent red or opaque red cast polypropylene (CPP) film is a versatile and durable packaging material that is used for

a variety of applications across different industries. Here are some of the primary uses of 50 micron translucent red or opaque red CPP film:

1. Food Packaging:

    50 micron CPP film is widely used in food packaging as it is food grade and provides excellent moisture barrier properties to protect the

    food from getting stale or losing its taste.

2. Gift Packaging:

    The red color and unique translucency of the film make it ideal for packaging gift items, gift certificates, and other decorative items sold

    in retail stores.

3. Stationery Packaging:

    The film is commonly used to package school supplies such as pencils, pens, and markers, as well as other types of stationery items.

4. Retail Packaging:

    Translucent red or opaque red CPP films are often used in the retail industry to package products such as toys, sporting goods,

    and household items.

5. Personal Care Packaging:

    The film's moisture barrier properties make it an ideal choice for packaging personal care products such as shampoo, conditioner,

    and lotion in bottles and tubes.

6. Industrial Packaging:

    The film's excellent puncture resistance, strength, and durability make it ideal for packaging industrial products such as tools and hardware.

Overall, 50 micron translucent red or opaque red CPP film is a popular packaging material that offers a unique and eye-catching appearance

as well as strong moisture resistance, strength, and durability. Its versatility makes it suitable for use in many industries and applications,

such as food, personal care, retail, industrial, and stationery.

 
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.
