Detection experiments of high-barrier and high-temperature sterilization and easy tear flexible plastic packaging materials applied in food packaging

摘要

In order to study the characteristics of a new kind of high-barrier and high-temperature sterilization and easy tear flexible plastic packaging materials applied in food packaging, the PET/AL/CPP was chosen as flexible plastic packaging material structure, different PET, CPP, alcohol inks, adhesives and other raw materials were selected for making a series of processing technology experiment and detection analysis. Then comparing the data obtained with the requirements, it was concluded that new flexible plastic packaging materials were extremely high resistance oxygen and resistance wet, high-temperature sterilization and good one-way easy tear, and etc.
