Background technique

Many consumable products, such as fruit juice, wine, tomato sauce, mixing beverage syrup, concentrate or the like is located in a package of a flexible sheet-like material (e.g., the cartridge and the film with aluminum layer) is made of. Typically, such a package may be used in consumer products has a flexible shape. Some packaging shape having a plurality of ridges (e.g., with a roof box). Packaging typically used is a large capacity bag in box packaging (Bag In Box, referred BIB package), which may be used for beverages or fluid-filled ready-to-drink concentrate.

Conventional BIB package is made of a laminated film, with two interfaces, one interface for filling, another interface for dispensing. Its production process is: firstly, a pre-made bags for later lamination film supplier, cap, and the tube is made of pre-made bags interfaces, two interfaces by way of communication with the interior of the bag is provided preformed on pre-made bags, the lid used to cover the live interfaces; secondly, the pre-made bags packed, transported to the irradiation for irradiation sterilization plant; again, the transport of the sterilized pre-made bags under aseptic bottling plant to storage conditions, by filling line for filling interface to the product pre-filled pouch; Finally, the preformed bag sealed and packed into the box to form the finished BIB package. Throughout the process, in order to ensure product quality, logistics process needs to be kept sterile, BIB packaging which resulted in high production costs and product quality are especially vulnerable. Further, the influence by the filling rate, the interface must be sufficiently large for filling. '
