1/ WHAT IS A CPP BAG?
CPP stands for Cast Polypropylene, which is a type of plastic film produced from PP resin by the casting method. Unlike BOPP (Biaxially-Oriented Polypropylene) film which is stretched in two directions, CPP film does not undergo an orientation process, creating a molecular structure with randomly oriented stretched chains
2/ CHARACTERISTIC
ADVANTAGE
High transparency and gloss: CPP film has good product visibility, creating attractive packaging.
Good sealing ability: Ensuring the tightness of the packaging
Good air and water vapor barrier: Helps preserve products better, keeping food fresh longer.
DISADVANTAGE
Mechanical strength is not as high as some other types of film: More susceptible to tearing and puncture than OPP and BOPP films
Cannot withstand high temperatures: May deform at temperatures above 100°C.
Difficult to decompose: Like many other plastics, CPP is difficult to decompose in the natural environment
3/APPLICATION
Food packaging: CPP is widely used in packaging of dry, wet, frozen, hot foods, foods that need to be steamed or dried
Pharmaceutical and veterinary packaging: CPP is also used to preserve medical products, veterinary drugs, and pesticides
As a laminate layer in complex packaging: CPP is often used as the innermost layer (welding layer) or middle layer in complex packaging, combined with other types of films such as OPP, PET to create packaging with many outstanding features.
CONCLUDE
CPP is a versatile plastic film, widely used in the packaging industry, especially food packaging, thanks to its advantages such as transparency, gloss, sealing ability, good air and water vapor barrier. However, it is necessary to pay attention to the disadvantages of CPP such as mechanical strength and high temperature resistance when choosing to use
