50 μm translucent white cast polypropylene film for food, medical can industrial packaging
50-micron translucent white cast polypropylene (CPP) film is a thin
and flexible packaging material that is commonly used in the
food, beverage, and cosmetic industries. Some of the primary uses
of this type of film include:
1. Food packaging:
50-micron translucent white CPP film is commonly used to package
food products such as snacks, confectionery, and baked goods.
The film is non-toxic and odorless, ensuring that it does not
affect the quality or taste of the packaged food.
2. Beverage packaging:
The film is also used to package beverages such as water, sports
drinks, and fruit juices. The film's high clarity ensures that the
liquid inside is visible to the consumer, while its strength and
flexibility provide a durable and reliable packaging solution.
3. Cosmetic packaging:
50-micron translucent white CPP film is popular in the cosmetic
industry, where it is used in the packaging of products such as
lotions,
shampoos, and conditioners. The film's high clarity allows the
product to be visible to the consumer, while its flexibility and
strength
ensure that the package remains intact during shipping and
handling.
4. Pharmaceuticals:
The film is also used in the packaging of pharmaceutical products,
such as pills, tablets, and capsules. The film's high barrier
properties
protect the contents from moisture, oxygen, and other environmental
factors that could affect the quality or efficacy of the
medication.
5. Adhesive tape:
50-micron CPP film is also used to make adhesive tapes for
packaging and stationery applications. The film's strength,
flexibility,
and translucency make it an ideal material for tapes that need to
withstand wear and tear.
6. Labels:
The film is also used to make labels for a variety of products in
different industries. The film's high printability and translucency
make it easy
to incorporate logos and designs onto the label.
Overall, the 50-micron translucent white CPP film is a versatile
and widely used packaging material that offers excellent clarity,
durability,
and flexibility. Its suitability for use in a wide range of
industries and its ability to keep packaged materials fresh and
protected have made
it a popular choice for many manufacturers.
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.
