Quality control of pet food package bag

For pet food manufacturers, choosing the right packaging materials is essential to ensure the shelf life of their products. Therefore, strict quality control of packaging materials and packaging is required.

It is well known that microorganisms need a certain environment to flourish, the three most important factors being ambient temperature, oxygen and moisture. Oxygen is the main external cause of rancidity, and the less oxygen there is, the less likely it is that rancidity will occur, while moisture provides an environment for microorganisms to operate, accelerating the hydrolysis of fats and shortening the shelf life of food. During the shelf life, the amount of oxygen and moisture in the packaging is more dependent on the integrity and barrier properties of the pet food packaging bag.

For pets to eat healthy and safe food, so pet food package bag need to have the following characteristics:

• tasteless, pollution-free, with good waterproof, moisture-proof and light-shielding functions.　
• high strength, high environmental protection, good heat sealability and firm sealing;　　
• good oxygen barrier and puncture resistance, can be stored at low temperature for a long time;
• good sealing performance, high barrier, oxygen and humidity permeability is ultra-low, high moisture resistance, puncture resistance and anti-tear performance;
•  
• As mentioned above, the integrity of the packaging can directly affect the shelf life of pet food. Therefore, to ensure the quality of pet food and to extend the shelf life of pet food, it is essential to test the integrity of the packaging. By testing the integrity of the packaging, pet food manufacturers can monitor the quality of the packaging and make timely adjustments to the packaging material or process based on the results, thus avoiding problems with the quality of the pet food due to the quality of the packaging.
