PETG、PCTG塑料具有优良的透明性、耐化学性、易加工性、环保健康等特点，它们被广泛用于加工各种高档塑胶制品。

ECOZEN材料除了具有PETG、PCTG的所有性能外，它还满足耐温的要求，另外，它的合成单体有部份是生物基材料，因此，它又是一种环保的生物基塑料。

去年，化妆品包装、食品包装、塑料膜等各行业倡导使用可回收的环保材料， ECOTRIA就是在合成时使用了部分回收PET材料的环保材料，它具很好的透明性与物理性能，它不会像普通回收PET材料那样有色泽变暗与透明度变差的问题。

ECOTRIA is SK chemicals' new high-transparent recycled material, a kind of PCR (Post-Consumer Recycled PET) produced from recycled materials and raw materials. It solves the problem of color and transparency deterioration of existing recycled PET materials, can be used in the fields of cosmetic containers, food containers, and heat-shrinkable film.

ECOZEN, the high-transparent bio-plastic, is one of SK chemicals' major materials. Last year, it introduced two new grades, ECOZEN Claro and ECOZEN HF. ECOZEN Claro is suitable for transparent cosmetic container materials because it can be produced by various molding processes while also having high transparency and chemical resistance. ECOZEN HF is a new material that is attracting attention as a container material for hot drinks and food because it has higher heat resistance than existing materials and does not shrink or deform.
