ABSTRACT:
Aseptically sterilized package of a liquid nutritional product manufactured by (a) providing a multi-layered plastic sheet having at least one polymeric structural layer and at least one polymeric barrier layer; (b) passing the sheet through a peroxide bath; (c) locating the sheet in a sterile environment; (d) applying heat a plurality of times to the sheet; (e) forming the sterilized sheet into a container having a body portion; (f) filling the body portion with a liquid nutritional product; (g) sealing the container with a tabbed, multi-layered closure; and (h) separating the sealed container from the remainder of the sheet. Preferably the liquid nutritional product is infant formula. In the preferred embodiment of the invention, the sheet is a laminate having two structural layers, each being about 45% of the laminate thickness and secured to either side of the barrier layer, which is about 5% of the laminate thickness, by an adhesive layer of about 2.5% of the laminate thickness. The container is prepared by thermoforming and deep drawing the multi-layered sheet. Pressure forming of the container is performed with the sheet temperature being 162.degree. C. using a plug-assist and a pressure of about 5 BAR. Once filled, the container is sealed using a thermo sealing process.
