摘要： A barrier foam tray contains recycled reclaim of barrier foam. The tray comprises a sheet of foamed polystyrene (PS) having laminated to it a flexible barrier film. The foamed polystyrene part can have admixed therein from 0.0001% up to 30% by weight of the flexible barrier film. The barrier film contains a barrier polymer such as ethylene vinyl alcohol copolymer (EVOH). The tray is made by grinding laminate scrap and extruding reclaim therefrom with virgin polystyrene.

摘要： The present invention relates to a food tray for supporting, containing and displaying food products which tend to exude or purge juices or liquids. In particular, the present invention relates to a food tray which comprises a sunken exudate reservoir. The reservoir is formed by adhering a sheet of a liquid impermeable material in a liquid tight manner to a raised shoulder area of a support portion of the tray to form a false bottom. The sheet material is further supported by standoffs rising up from the tray bottom. The sheet material is also perforated so as to allow flow of the exudate or purge through the sheet down into the reservoir where the exudate is trapped and retained out of contact with a food product which is located on top of said supported sheet. Preferably, the sheet material is opaque and the exudate is thereby hidden from view. Even more preferably, the sheet material is of the same color as the tray.
摘要翻译：食品托盘技术领域本发明涉及一种食品托盘，用于支撑，容纳和展示容易渗出或清除果汁或液体的食品。特别地，本发明涉及一种食物托盘，其包括凹陷的渗出物储存器。储存器是通过将液体不可渗透材料的片材以液密方式粘附到托盘的支撑部分的凸起的肩部区域而形成的，以形成假底部。片材进一步由从托盘底部上升的支座支撑。片材也被穿孔，以便允许渗出物或吹扫通过片材向下流入储存器，在该储存器中，渗出物被捕获并保持与位于所述被支撑片材顶部的食品接触不接触。优选地，片材是不透明的，并且渗出物因此被隐藏。更优选地，片材与托盘具有相同的颜色。

摘要： The present invention is directed to a method and apparatus for manufacturing a tray having an integral purge juice trap. A particularly important step in the method is adhering a border area of a perforated thermoplastic sheet to a raised shoulder area of a tray. Preferably, this step is accomplished simultaneously with the step of perforating the thermoplastic sheet. A preferred method for adhering the border area to the shoulder area is heat sealing.
