Inspection Of Sealing Properties Of Pet Food Bag

Sep 14, 2017

     With the development of economy and the improvement of people's living standard, pets more and more into more families, with the corresponding is the rapid development of pet food industry. The same as the general food industry, pet food industry also for product safety and quality of the corresponding requirements.Pet Food Bag

     Like other food, pet food has a certain time shelf life, in the shelf life, pet food to ensure that no deterioration or loss of nutrients and other problems. Many factors affecting the shelf life of pet food, such as the use of additives (preservatives), packaging, storage conditions (temperature, lighting, etc.). The purpose of this paper is to discuss the effect of barrier of packaging material on pet food shelf life and the method of barrier detection.Pet Food Bag

    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. 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
