Bioplastic Takes Higher Heat In Thermoformed Packaging

WEB EXCLUSIVE.

WEB EXCLUSIVE. A new thermoformable resin from Cereplast Inc. has higher heat resistance than competitive bioplastics and is also fully compostable. CP-TH-6000 is a PLA-based resin with heat resistance up to 155 C. The resin incorporates nanotechnology and a proprietary manufacturing process to boost heat resistance for packaging now made of PS, PE, or PET. The high-heat capability is partly obtained through processing, much like that for C-PET, according to William Kelly, senior v.p. of technology. He says time/temperature adjustments are required during the forming process to raise the sheet’s crystallinity and heat resistance. Mechanical properties are similar to Cereplast’s standard thermoforming resin, CP-TH-01. Application development efforts are currently focused on fast-food packaging.

    All things being equal, PET will outperform PBT mechanically and thermally. But the processor must dry the material properly and must understand the importance of mold temperature in achieving a degree of crystallinity that allows the natural advantages of the polymer to be realized.
