Plastic coating is a term that is commonly used in technology but is nevertheless ambiguous. It can be understood to mean the coating of plastic (e.g., metallization of plastics [ 1 ] ) or the coating of other materials (e.g., electrical cable ) with plastics.
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 ...
Liquid packaging board is a multi-ply paperboard with high stiffness, strong wet sizing and a high barrier coating, e.g. plastic. Only virgin paper fibers are used. The barrier coating must hold the liquid and prevent migration of air and flavors through the paperboard. [1]
Cold laminators range from simple two roller, hand-crank machines up to large and complex motor-driven machines with high precision rollers, adjustable roller pressure, and other advanced features. Cold lamination increased in popularity with the rise of wide-format inkjet printers, which often used inks and papers incompatible with hot lamination.
A film blowing machine involves one process used to make plastic film. Extruded tubular processing is most often used with polyethylene films but can be used with other polymers. [ 1 ] The film may be laminating film, shrink film , agricultural covering film, bags or film for textiles and clothing , and other packaging materials.
A typical industrial roll-to-roll process line. In the field of electronic devices, roll-to-roll processing, also known as web processing, [1] reel-to-reel processing or R2R, [2] is the process of creating electronic devices on a roll of flexible plastic, metal foil, or flexible glass. [3]
Limiting coating area is crucial in some applications, such as printing. "Roll-to-roll" or "web-based" coating is the process of applying a thin film of functional material to a substrate on a roll, such as paper, fabric, film, foil, or sheet stock. This continuous process is highly efficient for producing large volumes of coated materials ...
Heat sealer used to prepare plastic bag of lettuce for shelf life testing Continuous band heat sealer. A heat sealer is a machine used to seal products, packaging, and other thermoplastic materials using heat. This can be with uniform thermoplastic monolayers or with materials having several layers, at least one being thermoplastic.
