Is cat and dog food frequently spoiling, but the formula is fine? The root cause of the problem is likely to be in packaging inspection

The domestic pet economy has grown rapidly for many consecutive years. Pet owners treat cats and dogs as family, and their safety requirements for pet food are comparable to those of human food. Market supervision is becoming increasingly stringent, with product sampling, supermarket entry, and e-commerce listing all requiring complete packaging performance test reports. Small and medium-sized factories without standardized packaging quality control systems are about to be eliminated at an accelerated pace.

However, dry food is vulnerable to oxygen, freeze-dried food is vulnerable to moisture, and wet food is vulnerable to seal leakage, with vastly different quality control standards for pet food packaging across different categories. Little do they know, the real hidden culprits behind losses are the impaired barriers, sealing, and heat sealing indicators of aluminum foil bags, freeze-dried steaming bags, and wet grain composite bags.

As a one-stop service provider with nearly ten years of experience in food packaging, pharmaceutical packaging materials, and medical device testing instruments, we have launched a comprehensive packaging testing solution for pet food packaging at Zhongce Electromechanical. Below are some suggestions from an industry perspective.

1. Instruments are selected according to product category

1 Dry food / extruded food (cat and dog food pellets): focus on oxygen permeability + seal tester + tensile force machine to control oxygen infiltration and bag breakage during storage and transportation;

2. Freeze-dried / low-temperature roasted grains: prioritize water vapor transmittance tester + micro-leak sealing device, freeze-drying is highly sensitive to moisture damage;

3 Wet grain / canned soft bags: Heat seal strength tester + high-precision seal tester to prevent leakage at cooking seals.

2. Three key points to avoid when choosing a model

1. Precision Priority: Mechanical equipment preferably uses 0.1-level servo drive, blocking high-precision sensing from equipment; data traceability meets market sampling requirements;

2. Intelligent: Touchscreen + computer connection, automatic report generation, eliminating manual recording and saving quality inspection manpower;

3. After-sales Support: Priority given to manufacturers who can provide on-site commissioning and remote technical guidance to avoid equipment downtime.

From small and medium-sized OEM factories to leading private labels, hundreds of pet food companies nationwide currently choose Zhongce electromechanical testing equipment, relying on standardized quality control systems to break free from low-price competition and rely on stable quality premiums. In the future, Zhongce will continue to iterate on intelligent inspection models to help more pet food enterprises achieve standardized production and compliant overseas expansion.
