40 μm translucent white cast polypropylene film for food, medical can industrial packaging

40-micron translucent white cast polypropylene (CPP) film is a thin, flexible packaging material that is commonly used for

a variety of different applications, including:

1. Labels:

One of the most common uses of 40-micron translucent white CPP film is as a label material. The film can be printed with different

designs and graphics and is ideal for labeling products in various industries, such as food, beverage, cosmetics, and more.

2. Stationery products:

40-micron translucent white CPP film is used to make a wide range of stationery products, such as folders, paper clips, book covers,

notebook dividers, etc. The film's thin, flexible nature makes it easy to wrap around stationery items, and its translucency allows designs

and colors to show through.

3. Packaging for small products:

The film is also used as a packaging material for small products, such as buttons, hardware items, and small electronic components.

The white translucent color of the film gives the packaging an added layer of opacity while keeping the contents visible.

4. Retail packaging:

40-micron translucent white CPP film is frequently used in retail packaging applications, such as hangtags for clothing, or flexible packaging

for small items such as jewelry, nail polish, and other personal care items.

5. Tape:

The film is also used to make adhesive tape, such as stationery tape or packaging tape. The film's translucency allows the tape to blend in

with the background surface, giving a neat and clean appearance.

6. Lamination:

40-micron translucent white CPP film can also be used in lamination as a bonding material to provide added strength and durability to

other materials.

Overall, the thinness, flexibility, and translucent white color of 40-micron CPP film make it a versatile packaging and labeling material for

a wide range of industries and applications.

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.
