Applications of Pet Food Bags

Packaging is crucial in the pet food industry; it directly impacts food safety, freshness, and quality by preventing contamination and preserving nutritional value. It also provides pet owners with essential information-such as ingredients and feeding guidelines-that influences purchasing decisions, while simultaneously playing a key role in brand image and consumer convenience.
Pet food packaging is primarily categorized into rigid and flexible packaging. Rigid packaging typically refers to containers made from materials such as plastic, metal, or glass, whereas flexible packaging refers to packaging made from materials like paper or film [5].
Plastic packaging represents the largest segment of the pet food packaging industry; in 2024, the market size for plastic pet food packaging in China reached 10.557 billion yuan.
Generally, dry food and treats predominantly utilize plastic-based packaging, while wet food more frequently employs metal or aluminum-plastic composite packaging.
