They reduce the diameter of the workpiece as the pattern is applied. Whilst pack integrity tests will verify the seal quality of the blister before it leaves the line, consideration should also be given to any processes the pack will be subjected to after this stage. The flange of the blister is sealed and trapped between the front and back cards that are sealed together. A pair of scissors or a sharp knife is often required to open them (although these are often sold in similar packages). Coated PVC films have a thicknessof 8-10 mil; the thickness of the PVDCcoat amounts to 1-2 mil. End-Rolling Knurlers are used for entering a workpiece axially. The most basic material for the forming web is polyvinyl chloride (PVC). 0000051432 00000 n When sealed in one of these latter three methods, they can be frustrating and even dangerous to open for consumers, but are very tamper resistant as a result. For very deep draw thermoformed cavities, the triplex specifications are used: PVC/PE/PVDC, where the PE layer assists when forming deeper cavities. Ideal for creating sharp corners on softer materials. By contrast, the fragility and larger pocket size of CFF (Cold Formed Foil) blisters means they are better suited to platen sealing. Email: 2023 Accupack. Cyclic olefin resins are generally amorphous and are noted for good thermoforming characteristics even in deep cavities, leading some to use COC in blister packaging as a thermoforming enhancer, particularly in combination with semicrystalline resins such as PP or PE. Welcome to MSC, this site is screen reader friendly. The tool holder measures 5/16 wide x 3/4 tall. Heavy flow of coolant is suggested to ensure the knurl wheels remain both cool and clean.
