Product Description

CNP




Product Description


CNP is a functional PP film produced through a three-layer co-extruded biaxially oriented process. This film features two functional layers with characteristics such as ultra-low temperature heat sealing and high-temperature slip properties. It can achieve self-sealing over a wide temperature range and does not stick to conventional BOPP films.




Key Features


  • Excellent optical and abrasion resistance properties

  • Moisture, oxygen, and aroma barrier

  • Good low-temperature heat sealing performance with a wide heat seal range and high heat seal strength

  • Prevents adhesion to other films within a broad processing temperature range





Applications


  • Applied to bare packages of products such as cigarettes or cosmetics

  • Ideal for packaging products that are sensitive to high temperatures





Thickness


  • 21-28 micron




Application Recommentations:


  • Bottom and side sealing temperature : Recommended temperature 100-120 ℃,   depending on the running speed of the packaging equipment and the pressure of the iron;

  • Tobacco package beauty device: If used, it is recommended that the temperature does not exceed 110℃;

  • It is recommended that the product be stored in the production plant for 24 hours before use to ensure that the product runs more smoothly and firmly;

  • The outer surface of the product is highly slip-resistant, while the inner surface is intended to be in contact with the packaged product. Care should be taken to ensure the correct unwinding direction of the film roll during use.
