  2. Thermoforming - Wikipedia

    en.wikipedia.org/wiki/Thermoforming

    Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be ...

    en.wikipedia.org/wiki/Plastic_forming_machine

    Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, and stamped to a specific shape in a 2-part mold. Or a vacuum can be used to pull the plastic sheet onto the mold in a simplified process known as vacuum forming. The excess material is trimmed off and recycled.

    en.wikipedia.org/wiki/Vacuum_packing

    These are Form-Fill-Seal style machines that form the package from rolls of packaging film (webbing). Products are loaded into the thermoformed pockets, the top web is laid and sealed under a vacuum, MAP (modified atmosphere), or skin packaging producing rapidly packaged products. Thermoforming can greatly increase packaging production speed.

    Microthermoforming is the abbreviation for microscopic or microscale thermoforming, or, more precisely, for thermoforming of microproducts or microstructure products. . Microstructure products means products that have structures in the micrometre range and have their technical function provided by the shape of the microstruc

  8. Plastic extrusion - Wikipedia

    en.wikipedia.org/wiki/Plastic_extrusion

    A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...

  9. Blister pack - Wikipedia

    en.wikipedia.org/wiki/Blister_pack

    Unplasticised PVC has good thermoforming properties but may not provide good moisture protection for some products. After the forming process a 250 μm film will have a final thickness of 50 to 100 μm in some deep drawn pockets. The reduction in thickness will result in an increase in WVT. [9]
