Aluminum foil bags stratification cause analysis

Aluminum foil bags with a high barrier, moistureproof, prevent oxidation, puncture resistant, high temperature resistant, shading sex, such as performance, due to its excellent comprehensive performance, and in many food packaging applications. Especially cooking, high temperature disinfection, food packaging bags, basic it is use aluminum foil bag. But when we are cooking, high temperature sterilization, sometimes in aluminum foil bag of stratification. What are the cause of this phenomenon? Small make up here today to summarize a bags, aluminum foil composite strength too low this is the main cause of layered packet, when the composite strength is too low, each layer directly is particularly easy to peel, thus appear statified phenomenon. In a sealed bag, under the influence of the external environment, such as rubbing, cooking, such as high temperature, pulling, the film will directly affected by the magnitude of the different direction, when the power is greater than the strength of composite, layered. The causes of low strength of compound aluminum foil bag are: 1, viscose too little amount of coating is too thin, or uneven. Viscose is too little, and direct fusion of the films is not enough, viscous fluid nature is not enough, resulting in composite strength too low. Uneven, can cause the membrane stress change is big, and even some has space, so that to discover the surface, the weakest part of peel strength, is a composite strength standard. 2, the performance of the adhesive, such as viscose aging, not enough or curing degree and is used in coating, its viscosity is poor, viscous force is small, naturally composite is low natural strength. 3, composite curing room temperature too low or the time too short. After the completion of the thin film composite coating needs to be solid, is made of viscose viscous force to achieve the best effect. At low temperature, the outside has been solidified, and the internal is also no curing, the viscous force will become low. Time is too short, also can make viscose not completely cured, viscous force become low. So the composite strength will be too low. Two bags, aluminum foil of high temperature resistant properties of the aluminum foil bags in the room temperature strength of composite is very good, but under the condition of high temperature and peel strength sharply reduced, resulting in the stratification system. The main cause of this phenomenon is not high temperature resistant, under the condition of high temperature, melt glue and viscous force sharply lower. In addition there are many small bubbles in the viscose, in high temperature, the gas expands faster than the expansion of the solid or liquid, making the stripping the strength of the bags need to become more small, can also lead to inflation, layering. Three water resistance tape, aluminum foil bags sent this kind of situation mainly appear in the cooking bags, boiled disinfection or steam sterilization, contain water molecules. And under the condition of high temperature, water molecules become more active, viscose had almost insoluble in water, under the condition of high temperature, water soluble viscose saturation increases, if the water resistance of viscose, saturation sharp increase, the glue will have a lot of easy water, viscous force is reduced, resulting in stratification. Above is the aluminum foil bag layered three big reasons, hope to the problem of similar layered friend help. Tags: aluminum foil bag
