How to detect the quality of composite aluminum foil bags?aluminum foil bags for grilling Manufacturing

　　1. Detecting appearance

　　The appearance is the most direct way to judge the quality of aluminum foil bags. By detecting the appearance, you can find out whether the composite bag is flat, whether there are brushed, fog editions, and leaks.

　　In order to avoid these problems, the production process of packaging Co., Ltd. strictly controls the quality of raw materials to achieve unqualified raw materials and does not enter the warehouse to ensure that the material itself is thin and uniform, and problems such as poor transparency or poor flatness.

　　We found that the aluminum foil composite bag was brushed, most of the reasons because the bag making machine was not clean or the guide roller was not rotated. Therefore, the guidance roller is ensured during the production process, and the guidance roller bearing is added with lubricant to ensure the normal operation of the guide roller.

　　2. Detecting sealing density

　　Sealing and sealing is the key element of the quality of composite aluminum foil bags. The strong sealing aluminum foil bag can extend the shelf life of food to a certain extent. If the sealability is poor, the food may be deteriorated. The commonly used method is to spray a surfactant with dyes in the seal and observe whether it is through. If the dye color is sealing, it means that the sealing performance is not good, and on the contrary, it means that the sealing quality requirements are met.

　　In order to ensure that the product is well -dense, it is necessary to have a uniform and stable seal pressure and the appropriate temperature. When producing compound aluminum foil bags, the sealing spring pressure will be adjusted according to the actual situation to ensure that the pressure of the knife is uniform. In terms of temperature, you choose an experienced master and advanced equipment to ensure that the temperature is appropriate.

　　Third, detect the seal intensity

　　The sealing intensity is the most intuitive manifestation of the function of the composite aluminum foil bag to protect the product. It can be tested by the method of tearing the aluminum foil bag. However, it cannot be said that the sealing strength is low. It must be bad quality. The sealing strength is generally related to the material. Generally, aluminum foil bags made of OPP heat -sealing film are easy to tear, suitable for light quality products. Aluminum foil bags with composite nylon and high -pressure membranes are difficult to tear away. They can install products with heavy quality.
