Ordinary <span style="color: rgb(51, 51, 51);">spout pouch</span> are mainly considered for safety, firmness, and reusability issues, such as liquid packaging bags and laundry liquid packaging bags. For high-temperature cooking bags, food safety issues must be considered. How to ensure that the packaging solvent is not dissolved during the high-temperature cooking process. And it can also ensure that the nutritional content of the product is not lost and the taste is not changed.</p><p><br></p><p>一. Ordinary spout pouch</p><p>1.Common materials: PET / PE, PA / PET / PE, PET / PE / aluminum / YOPP, PET / PE / YOPP, etc.</p><p>2. There is no particularly high requirement for the solvent of the material of the ordinary spout pouch, as long as the material can be stable at normal temperature, chemically stable, non-toxic and tasteless, and will not decompose. Has a certain resistance to acid, alkali, anti-blasting rate!</p><p>3. Control the film's friction coefficient. When the automatic filling machine is filling, the inner and outer surfaces of the packaging film should maintain good smoothness, so that the automatic packaging machine can increase the fluidity of the liquid smoothly during high-speed operation. Carry out filling.</p><p> 4. Pay attention to the nature of the material when matching the material. If the material is too soft, the tension of the suction nozzle packaging bag will be poor, there is no three-dimensional feeling, and it is easy to break under the action of the high-speed automatic filling machine.</p><p><br></p><p>二. High-temperature cooking spout pouch</p><p>1. Common materials recommended</p><p>Three-layer material: PET / pure aluminum / RCPP, PET / PA / RCPP</p><p>Four-layer material: PET / pure aluminum / PA / RCPP</p><p>2. Due to special applications, material properties will be taken as the key consideration criteria. Such as acid resistance, alkali resistance, impact resistance, anti-freezing, and barrier properties.</p><p>3. The above materials have extremely stable chemical properties at high temperatures. Regarding whether the complex solvent will decompose, it is recommended to choose a packaging bag manufacturer with scale and experience.</p><p>4. Pay attention to sterilization methods. There are two methods for high-temperature sterilization, high temperature, and high-pressure sterilization and low temperature and normal pressure sterilization. The advantage of low-temperature and normal-pressure sterilization is that the stability of heating is relatively low, so the cellulose and protein of the food are not damaged, and the mouthfeel is better retained and the taste is not changed. And all kinds of nutritional ingredients are well preserved. The disadvantage is that because the low temperature only kills the pathogenic bacteria, there will still be a lot of spoilage bacteria in the food, so the shelf life of the food will be shorter than that of the high-temperature sterilization, and it will easily cause product loss during transportation. High temperature and high-pressure sterilization just solves this problem. Most bacteria and spoilage bacteria will be killed in the high temperature and high-pressure environment, so the shelf life of the product can be greatly extended. However, there is a problem in that the heating temperature is high, and the cellulose and protein of the food will be damaged, resulting in the loss of some nutrients in the food and the taste will be reduced.</p><p><br></p>
