50 Micron Translucent Blue CPP Plastic Films High Seal Strength

Product Specification

50 μm blue cast polypropylene film for food, medical can industrial packaging

50 micron translucent blue or opaque blue cast polypropylene (CPP) film is a packaging material that is commonly used for various applications.
Some of the main uses of 50 micron translucent blue or opaque blue CPP film are:
 
1. Food packaging:
    50 micron translucent blue or opaque blue CPP film is widely used for packaging food products such as snacks, baked goods, and
    confectionery. Its high puncture resistance and excellent sealing properties make it an ideal option for food packaging applications.
 
2. Cosmetic and personal care products:
    The film is often used to package cosmetic and personal care products such as shampoos, lotions, and soaps.
    The high clarity of the film allows the product to be visible, while the excellent sealing properties help to maintain product freshness and
    protect against spills.
 
3. Labeling and printing:
    50 micron translucent blue or opaque blue CPP film is used for making labels for a broad range of products, including food, beverage,
    and cosmetic packaging. Its high printability and translucency make it easy to incorporate logos and designs onto the labeling.
 
4. Industrial packaging:
    50 micron translucent blue or opaque blue CPP film is used for packaging industrial products such as tapes, adhesives, and sealants.
    The strength and puncture resistance of the film ensure that the products are protected during transportation.
 
5. Apparel packaging:
    The film is used for packaging clothing and other textile products. Its strength, durability, and puncture resistance make it a great choice for
    packaging materials that require protection from external factors.
 
6. Stationery and office supply packaging:
    The film is used for packaging stationery, office supplies, and other miscellaneous items. Its strength and puncture resistance make it
    an excellent choice for protecting these products during transportation.
 
Overall, 50 micron translucent blue or opaque blue CPP film is a versatile and durable packaging material that finds use in various industries
due to its high puncture resistance, excellent sealing properties, good printability, and barrier protection. It is an ideal choice for packaging
applications that demand more thickness than thinner transparent films.
 
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.
