Pet food generally contains protein, fat, amino acid, minerals, crude fiber, vitamins and other ingredients, which also provide good breeding conditions for microorganisms. Therefore, to ensure the nutritional value of dog food, it is necessary to inhibit the activity of microorganisms. There are three elements that microorganisms depend on for survival: ambient temperature, oxygen and moisture. During the shelf life, the content of oxygen and moisture in the package depends more on the integrity and barrier properties of the pet food packaging bag. Among them, the perfect packaging has the most direct impact on shelf life.
At present, the common pet food packaging on the market includes plastic flexible packaging, composite plastic packaging, center-sealed organ bag, paper-plastic packaging, aluminum-plastic packaging, and tinplate packaging cans. No matter what kind of packaging, the integrity of the packaging is very important. If the packaging has pores or air leaks, oxygen and water vapor will enter the packaging bag, causing qualitative changes in pet food. The use of a composite structure can effectively improve the overall force-bearing capacity and barrier performance of the package.
If the peel strength is too low, it means that the composite quality is poor, and the packaging bag cannot better realize the quality expectations of multi-layer materials dispersing force and acting as a barrier. The package is easy to break when dropped, and the barrier performance is lower than expected. Heat seal strength represents the strength of the package seal. If the heat seal strength is too low, it will easily cause the seal to crack and pet food to scatter during the handling process, causing the pet food to come into contact with oxygen and moisture in the air, and the food is prone to mildew.
The overall airtightness of pet food bags such as dog food bags and cat food bags is very important. If the packaging is incomplete, undoubtedly under the action of oxygen and moisture in the air, the pet food will easily become moldy and deteriorate, and the nutrients will also be lost. When consumers buy food for their pets, they must carefully check whether the pet food packaging bags are complete and free of leaks.
