Waterproof Sealing Of Pet Food Bag

Sep 25, 2017

     It is well known that microbial breeding needs a certain environment, of which the three most important factors are ambient temperature, oxygen and moisture. Oxygen is the main external cause of rancid, oxygen content is less, the likelihood of spoilage, and water can provide the environment for microorganisms, accelerate the hydrolysis of fat, shorten the shelf life of food.

    In the shelf life, the oxygen and moisture content of the packaging is more dependent on the integrity and barrier properties of the pet food packaging bag. The barrier properties of packaging materials are particularly important for the shelf life of pet food.Pet Food Bag

    During the shelf, the oxygen and moisture in the complete pet food package comes mainly from the oxygen and water vapor that permeates through the packaging. Barrier is the blocking effect of packaging materials on the permeation of gases or liquid molecules through materials. Pet Food Bag

    Select seven kinds of pet food packaging materials in the market pet, Pet+cpp, Bopp/cpp, Bopet/pe, Opp/pe/cpp, BOPET/VMPET/LDPE and aluminum-plastic composite film, respectively, the oxygen transmittance and water vapor transmittance of the test, analysis and comparison. The greater the oxygen transmittance, the worse the oxygen resistance of the material, the greater the water vapor transmittance, the worse the moisture resistance of the material.Pet Food Bag

    Film on pet packaging materials water vapor transmittance has improved, pet packaging bags of poor moisture resistance, is not conducive to pet food storage, the packaging of pet food shelf life is short. The barrier of packaging material is crucial to the effect of pet food shelf life. Pet Food Bag

    Manufacturers in the selection of packaging materials should pay attention to the selection of high barrier properties of composite plastic flexible packaging, aluminum-plastic composite materials or tinplate material.Pet Food Bag
