    Abstract: A use of a low specific gravity PET composite material that is suitable for manufacturing a tableware article by injection molding is provided. The tableware article provides a balance between aesthetic appearance and food safety and can be used in place of melamine tableware. The low specific gravity PET composite material includes 66.5-96.3 wt % of PET, 0-20 wt % of PBT, 3-10 wt % of an inorganic filler, 0.1-0.5 wt % of an antioxidant, 0.1-1 wt % of a processing aid, and 0.5-2 wt % of a nucleating agent, and the total amount of all components is 100 wt %.

    Abstract: A peelable protective film having perfect adhesion for providing temporary protection to objects is disclosed, which protective film having a peel strength ranging between 35 and 100 g/cm is capable of being easily peeled off from an adhered object and without leaving any residual adhesive; a composition containing a vinyl chloride-vinyl acetate copolymer, a high-molecular-weight emulsified, polymerized PVC powder, a low-molecular-weight emulsified, polymerized PVC powder, a trimellitate plasticizer, a diisobutyrate-based plasticizer, a phenol-free Ca—Zn stabilizer, fumed silica, aluminum hydroxide, barium sulfate and calcium carbonate is so suited for making the peelable protective film having a thixotropic index ranging between 2.00 and 2.20.
