Three elements of the process of steaming bags

　　The three elements of steamed bags are mainly speed (time)/min, temperature (℃), and pressure (n). After the composite material is familiar with, first detect the composite fastness and residual solutions between the layers. After the data meets the requirements Only then can you take it out and take it. It is made of a patent bag with a composite film. Generally, it is sealed to make a flat bag or an independent bag. It is basically not made into a mid -sewing bag shape. The process parameters of the cooking bag are mainly temperature, pressure, and time. They are mutually complementary and mutually dependent relationships. Among them, temperature is a dominant role, and pressure and time are auxiliary effects. If the temperature is too low and the pressure time, the pressure time will not make the hot sealing layer reaching the degree of melting self -adhesion.

　　Different structures, different combinations, and composite films of the cooking bag have different thermal seals and can be between 45-80N/15mm. For composite film with different structural combinations and different layers, the process parameters of the cooking bag should also be different.

　　The process parameters of the cooking bag are mainly temperature, pressure, and time. They have a complementary and mutual dependence between them. Among them, the temperature is dominant, and the pressure and time are auxiliary effects. The cooking bag uses a CPP film or HDPE film as a hot seal layer. Their melting point is higher than LDPE, so the temperature of the hot knife is much higher than that of the LDPE membrane, most of which are selected between 180-230 ° C. If the temperature Too low, no matter how strong the pressure, no matter how long the pressure is, it cannot make the CPP reach the degree of melting self -adhesion. Only by selecting the suitable temperature, and then through a certain contact pressure and contact time, can the purpose of the cooking bag can be completed Essence
