Consumer Packaged Products
The two primary components of a blister package are the cavity and the lid stock. The cavity is made of thermoformed plastic, while the lid can be paper, paperboard, plastic, aluminum (usually an aluminum foil) and most recently, pulp. In a typical sealing operation, heat and pressure activate an adhesive coated on the blister card. Blister packs can have push-through or peelable lids.
Clamshell packaging consists of two pre-formed substrates. This type of package is typically more tamper-proof than a blister pack. PVC and PET are currently the two most popular materials used in these packages.
In the retail market, the trends driving the market are: cost of the materials and the desire to automate as much of the process as possible, fast changeover to accommodate shorter runs of each type of package, and increased throughput.
In addition, manufacturers are looking for systems that can handle a range of new materials, including sustainable materials like RPET and most recently, pulp. SencorpWhite’s CeraPak sealers have the capabilities to accommodate the latest in material trends and requirements.
