Testing standards for pet food packaging are a set of technical specifications established to ensure the quality and safety of pet food during storage, transportation, and sale. These standards cover aspects such as the performance, safety, and environmental friendliness of packaging materials, as well as the soundness of the packaging design. Implementing these standards effectively prevents packaging materials from contaminating or damaging the pet food, thereby safeguarding pet health and protecting consumer rights. This document details the relevant standards and testing methods for pet food packaging.
Material Safety
1. Non-toxic and harmless: Packaging materials must comply with food safety standards and must not contain substances harmful to humans or pets. For example, the content of phthalate plasticizers in plastic packaging materials must not exceed 0.1%.
2. Odor-free: Packaging materials should be free from pungent odors to avoid adversely affecting the flavor and texture of the pet food.
3. Biocompatibility: Packaging materials should possess good biocompatibility and must not undergo chemical reactions with the pet food that would compromise its quality.
Material Performance
1. Mechanical strength: Packaging materials should possess sufficient mechanical strength to withstand physical stress during transportation and storage. For example, the compressive strength of cardboard boxes should be no less than 200 N/cm².
2. Moisture resistance: Packaging materials should exhibit good moisture resistance to prevent the pet food from becoming damp and spoiling. For example, the water vapor transmission rate of composite bags should be less than 5 g/m²·24h.
