用于成型、填充和密封模具的装置和方法以及由其形成的包装
摘要：
本申请提供了用于膜密封模具的装置和方法，且具体地涉及用于成型、填充和密封(FFS)过程中的膜密封模具的装置和方法。用于密封塑料膜材料的装置包括加热机构，所述加热机构包括加热凸缘(110)，所述加热凸缘(110)设置成当塑料膜(120)与加热凸缘(110)接触时，加热凸缘(110)在塑料膜(120)上形成热密封件；和冷却机构，所述冷却机构包括气体喷射管道，所述气体喷射管道定向成以在0°至60°之间的接触角接触塑料膜(120)上的热密封件，使得形成在塑料膜(120)上的热密封件在小于或等于5秒内冷却至小于或等于40℃的温度，从而形成密封的塑料膜。
摘要（英）：

Provided herein are apparatus and methods for film sealing dies, and in particular, to apparatus and methods for film sealing dies in form, fill and seal (FFS) processes. An apparatus for sealing plastic film materials includes a heating mechanism, the heating mechanism including a heating lip (110) arranged such that when a plastic film (120) is contacted with the heating lip (110), the heating lip (110) forms a hot seal on the plastic film (120); and a cooling mechanism, the cooling mechanism comprising a gas jet duct oriented to contact the hot seal on the plastic film (120) at a contact angle between 0 and 60° such that the hot seal formed on the plastic film (120) is cooled to a temperature of less than or equal to 40°C in less than or equal to 5 seconds to form a sealed plastic film.
