Flexible Packaging

The extrusion process is used to manufacture plastic film and sheet. The resin is pushed or drawn through a die of a predetermined thickness or cross-section. The main advantages of this process over other processes are its high volume, an ability to create very complex cross-sections and to shape materials that are brittle (because the material only encounters compressive and shear stresses).

Takween uses extrusion to manufacture polystyrene sheet rolls that are subsequently thermoformed into cups and lids in a single process. This is a high volume manufacturing process where the plastic raw material is melted and formed into a continuous sheet (or profile) and then cooled through a set of rolls that determine the sheet’s thickness and surface texture. The sheets are then sent for thermoforming.
