AS is the better choice for pet food packaging due to its superior barrier properties and recyclability.

AS, or acrylonitrile styrene, offers excellent moisture resistance and keeps the food fresh for longer.

PET, on the other hand, is less effective in preventing moisture transmission, potentially leading to spoilage.

In addition, AS is widely accepted for recycling, making it a more sustainable option.

PET, although recyclable, poses challenges due to its complex recycling process and limited reuse potential.

Using AS for packaging helps reduce environmental impact and supports circular economy efforts.

Furthermore, AS provides better protection against light and oxygen, preventing nutrient degradation.

PET, however, may allow more light infiltration, leading to reduced product quality and shelf life.

Choosing AS ensures optimal preservation of essential nutrients in pet food.

In conclusion, AS surpasses PET in terms of barrier properties, recyclability, and protection of pet food quality.

Considering the importance of food safety and environmental responsibility, AS emerges as the preferred packaging material for pet food.
