The term aseptic packaging is used to refer to a carton that is made from a foil-barrier material. There are rapid changes that are taking place in the field of aseptic packaging. The different technological advancement is to meet the demands of customers in filling where aseptic packaging material has to come into consideration. You can find aseptic elements produced by any of the three big suppliers which have the aseptic liquid systems intellectual rights in the whole world. An example of aseptic packaging material includes the bottles made of polyethylene and terephthalate. Another common product used is high density polyethylene that is becoming more common for aseptic beverage filling. Aseptic multilayers can be formed into aseptic containers that look like bottles rather than using the traditional method of brick pack drink box. Film-based aseptic packaging material has made aseptic stick pack to be an option for a good number of years. This has raised the option for consumption of products such as applesauce and pudding. There are also many companies that supply the high-barrier laminated films that are used to vertically form, fill and seal both pudding packages. In creating laminated structures for aseptic packaging material applications, you should understand that the aseptic process and equipment dictates how robust the material should be. Hydrogen peroxide is a good aseptic material that is used to sterilize film -based materials before aseptic VFFS filling. The film travels through a heated peroxide bath for the purpose of sterilization. The material might spend some considerable amount of time there. Meanwhile, the equipment operator splices in a new roll of film. This can even go for an entire weekend in case the machine is shut down. One requirement is that the film-based material should be in a position to withstand those minutes and hours that they are in the peroxide without any problem of delaminating. Polypropylene, polyolefin and polyester (linear low density polyethylene) are a pack of good aseptic packaging materials that are robust enough to enable the other materials that maintain the integrity of the hydrogen peroxide. Another factor that has to come in consideration when using aseptic materials is the material that is used for lid. If the aseptic process uses the horizontal form-seal technology, you are advised to use an extrusion lamination rather than an adhesive lamination because the later tends to curl severely during steam sterilization. More over, the HFFS material used for lidding should be thick so as to make to withstand the pressure used to seal the lidding to the thermoformed cup.
