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

50 micron translucent yellow or opaque yellow cast polypropylene (CPP) film is a sturdy and durable packaging material.

Here are some of the primary uses of 50-micron translucent yellow or opaque yellow CPP film:

1. Food Packaging:

50-micron CPP film is suitable for packaging food that needs to be protected from oxygen and moisture.

The yellow color of the film provides a more attractive appearance, making the food package more appealing to the consumer.

2. Stationery Packaging:

The thick and sturdy nature of 50-micron CPP film makes it an ideal choice for packaging stationery items like pens, pencils, and markers.

Its high clarity and stiffness protect the contents from damage during transportation.

3. Medical and Pharmaceutical Packaging:

The film's high moisture and gas barrier properties make it ideal for packaging medical and pharmaceutical products.

It ensures that the contents remain sterile and protected.

4. Industrial and Heavy-Duty Packaging:

50-micron CPP film is used to package heavy-duty industrial products like machinery parts, construction equipment, and other industrial

items necessary to be transported over long distances without wear or damage.

5. Packaging of Chemicals:

The high gas barrier properties of 50-micron CPP film make it ideal for packaging hazardous chemicals.

It ensures that any hazardous material is tightly sealed in the packaging.

6. Retail Packaging:

50-micron translucent yellow or opaque yellow CPP film is suitable for retail applications, as it provides a visual display of products, making

them more accessible to consumers.

Overall, 50-micron translucent yellow or opaque yellow cast polypropylene film is a durable and sturdy packaging material suitable for different

applications, including food packaging, medical, pharmaceutical, and retail packaging. Its high gas and moisture barrier properties make it ideal

for packaging of industrial products and hazardous materials.

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.
