Polyamide (PA) Film (Nylon Film)  

PA film (commonly known as nylon film) is mainly dominated by ”Biaxially Oriented Polyamide (BOPA)“,

featuring excellent flexibility and puncture resistance.  

Advantages:  

 - Exceptional flexibility, along with strong impact resistance and puncture resistance,

   making it suitable for packaging sharp or hard products (such as bones, hardware parts);    - Good oil resistance, capable of blocking oil penetration, ideal for packaging meat and fried foods;    - High low-temperature resistance (maintaining toughness even at -40°C), suitable for frozen food packaging;    - Excellent compatibility with other materials, often used as an intermediate

    layer to enhance the overall strength and barrier properties of packaging.  

Disadvantages:  

 - High cost, much higher than PE and PP; generally not used alone as a printing layer, but mostly combined with other films;    - Strong hygroscopicity, prone to deformation in humid environments, which affects dimensional stability;    - Moderate barrier properties (better oxygen barrier performance than PE and PP, but inferior to PET and aluminum foil).  

Applicable Scenarios:  

     Frozen food packaging (e.g., quick-frozen dumpling bags), meat packaging (e.g., ham vacuum bags),

  and oil-based product packaging (e.g., nuts, fried snacks).
