Product Details

Clear CPP Polypropylene Film 30μm For Food and Vegetable Packaging

 

Description:

 

Polypropylene film or PP is a low density plastic film. The most important types of PP are cast polypropylene (CPP) and bi-axially oriented polypropylene (BOPP). Pinetree offer both these types of PP films. While BOPP is a more commonly known polypropylene film, the use of CPP in the food, pharmaceutical, flower, textiles and several other industries are consistently gaining popularity.

 

Cast polypropylene film is gaining favour as the material of choice in both traditional flexible packaging as well as non-packing applications. CPP has a higher tear and impact resistance, and better cold temperature performance and heat-sealing properties as compare to BOPP. There are various type of CPP films like general CPP, Anti-fog CPP and several other applications depending on the requirement and end application.

 

Some of the major benefits of CPP are listed below:

  • Excellent heat seal strength, high puncture and tear resistance
  • Excellent packaging integrity at extreme temperatures and high heat resistance
  • No impact on the coefficient of friction (COF) control
  • High yield per unit area and low specific weight (0.91 g/cm3)
  • Offers good moisture barrier
  • High transparency

Applications:

 

The health care and pharmaceutical industries use CPP films for packaging of drugs for extended periods of time since CPP films can protect against contamination. Application in other industries includes stand-up re-closable pouches, multi layered laminations, side-weld seal bags, flower and twist wraps.

 

Some of the major applications of CPP are listed below:

  • Food Wraps or Candy/Confectionery packaging
  • Bakery Products
  • Lamination
  • Garment Bags
  • Retort Packaging
  • Stationery Packaging
  • Vacuum Metallization
  • Deep Freeze Application
  • Over Wrap
  • Floral Wraps
