Thermoform Plastic Sheets Evoh

Thermoforming can range in complexity from manual operations to highly automated large scale ones.

Thermoform plastic sheets evoh.

Thermoforming requires lower pressures and the machinery can be less rigid and less expensive to produce. 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. Thermoforming can be a low cost alternative to processes such as injection moulding and blow moulding. 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 offers processing advantages over competitive processes such as blow molding and injection molding. More specifically the present invention is directed to an innovative thermoforming process comprising an ascending descending backpressure profile.

Amorphous plastics like abs and polycarbonate generally have wide processing windows and good melt strength making them easy to thermoform. The present invention relates generally to a process for thermoforming containers containing ethylene vinyl alcohol evoh barrier resin. 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. 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.
