Thermoform Plastic Sheets Evoh

Thermoforming offers processing advantages over competitive processes such as blow molding and injection molding.

Thermoform plastic sheets evoh.

In the thermoforming process a plastic sheet usually produced by an extruder is softened by heat and then placed on one half of a mould. 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 refers to the process of heating and shaping a plastic sheet on a mold.

Thermoformed sheet plastic thermoformed cups are continuing to emerge in the market because they are an excellent alternative to glass and metal containers. Amorphous plastics like abs and polycarbonate generally have wide processing windows and good melt strength making them easy to thermoform. Some plastics like hdpe and pp have narrower processing windows and lower melt strength which make them more difficult but not impossible to thermoform. Thermoforming can be a low cost alternative to processes such as injection moulding and blow moulding.

More specifically the present invention is directed to an innovative thermoforming process comprising an ascending descending backpressure profile. Many plastic sheet materials can be shaped by thermoforming. Thermoforming requires lower pressures and the machinery can be less rigid and less expensive to produce. Thermoforming can range in complexity from manual operations to highly automated large scale ones.
