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.
