Thermoform Plastic Sheets Evoh

More specifically the present invention is directed to an innovative thermoforming process comprising an ascending descending backpressure profile.

Thermoform plastic sheets evoh.

High barrier sheets pp evoh pp with high oxygen gas aroma and water vapor barrier ps evoh ps for processed cheese fruit desserts fruit juices uht milk ps evoh pe for modified atmosphere packaging such as pasta salads sauces pate ps evoh pe pp for long shelf life products such as drinks fruit juices tomato paste pe pp evoh pp for packaging of pasteurized fresh food. With a layer of eval in the thermoformed sheet the barrier needed to obtain sufficient shelf life and product stability in order to replace glass and metal packages is easily achieved. Many plastic sheet materials can be shaped by thermoforming. Thermoformed pp high barrier evoh sheets for food pp evoh pe designed for the food industry these special co extruded sheets are laminated with a high barrier film of ethylene vinyl alcohol which is very effective at excluding air and protecting the flavour of the food extending its shelf life and quality.

Thermoforming offers processing advantages over competitive processes such as blow molding and injection molding. Thermoforming can be a low cost alternative to processes such as injection moulding and blow moulding. Thermoformed sheet plastic thermoformed cups are continuing to emerge in the market because they are an excellent alternative to glass and metal containers. Thermoforming refers to the process of heating and shaping a plastic sheet on a mold.

Amorphous plastics like abs and polycarbonate generally have wide processing windows and good melt strength making them easy to thermoform. Thermoforming requires lower pressures and the machinery can be less rigid and less expensive to produce.
