As people’s material life gradually increases, the number of pet households increases gradually, pets gradually become one of the important members of the family, and the development of the pet food industry is promoted.Like our daily food, pet food is also a product quality and safety requirement.Pet food has the same shelf life requirement. During the shelf life, pet food must ensure that no spoilage, odor, nutrient loss, etc.There are many factors that influence shelf life, including preservatives, packaging, storage conditions and so on. Here we will focus on pet food packaging bags.
Pet food generally contains protein, fat, amino acids, minerals, crude fiber, vitamins and so on. These ingredients also provide good breeding conditions for microorganisms.Therefore, to ensure the nutritional value of pet food and prolong shelf life, the activity of microorganisms should be suppressed.The three elements that microorganisms depend on: ambient temperature, oxygen and water.In shelf life, the amount of oxygen and moisture in the packaging depends more on the integrity and barrier properties of pet food packaging bags.Among them, the integrity of packaging has the most direct impact on the shelf life.
The more common pet food packages in the market include plastic soft packing, self-supporting zipper bag, composite plastic packaging, paper plastic packaging, aluminum plastic packaging and tin plate.Whatever the packaging, the integrity of the packaging is very important.If the packaging has pores or leaks, oxygen and water vapor will enter the bag, resulting in a qualitative change in pet food.The integrity of the package is easy to be found in the hot seal of the packet, the bucket cover of the package, etc.
At present, the common pet food packages on the market with plastic flexible packaging, composite plastic packaging, eight edge-sealing self-reliance bags, organ bags, paper-plastic packaging, blister packaging and tin tins, the most commonly used for zipper free-standing composite plastic soft packing and blister packing.The composite structure can effectively improve the stress and barrier properties of the package.
If the peel strength is too low, the compound of poor quality, packaging can not be well implemented multilayer material dispersion force, common have the quality expectations of barrier property, packaging easily broken falls, blocking performance fell short of expectations.The heat seal strength represents the strength of the packing seal.If the heat seal is too low, it can easily cause the sealing crack and pet food to be scattered in the handling process, resulting in the contact of oxygen and water in the pet food and air, and the food is easy to mould.
As a result, the overall seal of pet food packaging bags is very important.If the packaging is not complete, it is clear that in the air of oxygen and water, pet food can become moldy, and the nutrients are lost.When buying food for your pet, you must carefully check whether the pet food package is complete and not leaking.
