POLYESTER COPOLYMER HAVING EXCELLENT CHEMICAL RESISTANCE AND TRANSPARENCY
The polyester copolymer according to the present invention is excellent in chemical resistance and transparency and thus can be usefully applied to the production of various containers.
Method for reproducing polyester container and reproduced polyester chip prepared therefrom
Embodiments relate to a process for regenerating a polyester container and regenerated polyester chips prepared therefrom. The process comprises preparing a polyester container provided with a heat shrinkable film; crushing the container provided with the heat shrinkable film to obtain flakes; and thermally treating the flakes to produce regenerated polyester chips, wherein when the flakes are thermally treated at a temperature of 200° C. to 220° C. for 60 minutes to 120 minutes, the clumping fraction is 5% or less, and the flakes comprise first flakes obtained by crushing the container and second flakes obtained by crushing the heat shrinkable film. It not only solves the environmental problems by improving the recyclability of the polyester container, but also is capable of enhancing the yield and productivity.
MOLDED ARTICLES FOR USE WITH TERPENE CONTAINING OILS
A shaped article comprising a molded component configured to receive a terpene containing oil composition, said molded component formed of a copolyester composition having high chemical resistance to terpene oil and having a Tg of at least 95 C.
POLYESTER FILM AND METHOD FOR REPRODUCING POLYESTER CONTAINER USING SAME
The embodiments relate to a polyester film, which comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80 C. for 10 seconds and a melting point of 170 C. or higher as measured by differential scanning calorimetry, which not only solve the environmental problems by improving the recyclability of the polyester container, but also are capable of enhancing the yield and productivity, and a process for regenerating a polyester container using the same.
POLYESTER RESIN
The present invention relates to a polyester resin. The polyester resin is useful for bottles, sheets, multilayer sheets, stretched films and fiber applications due to excellent heat resistance and transparency, and in particular, the polyester resin has little deterioration of physical properties such as yellowing, etc., during processing
ADHESIVE, LAMINATED FILM, AND PRODUCTION METHOD FOR LAMINATED FILM
Provided are an adhesive including a polyisocyanate composition (X) containing a polyisocyanate (A), and a polyol composition (Y) containing a tertiary amine compound (B) having plural hydroxyl groups, a polyol (C), and an aliphatic cyclic amide compound (D), as essential components, a laminated film using the adhesive, and a method for producing a laminated film including a step of separately applying two components, which includes bringing a polyisocyanate composition (X) containing a polyisocyanate (A) that is applied onto one base material into contact with a polyol composition (Y) containing a tertiary amine compound (B) having plural hydroxyl groups, a polyol (C), and an aliphatic cyclic amide compound (D) that is applied onto the other base material, and performing pressure-bonding.
A COATING COMPOSITION
A coating composition comprising: a. a polyester imide (PEI) polymer having an acid value of 10 mg KOH/g; and b. a crosslinker operable to crosslink the acid functionality on the polyester imide polymer wherein the coating composition is substantially free of bisphenol A (BPA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
Heat shrinkable film and method for reproducing polyester container using same
A heat shrinkable film and a process for regenerating a polyester container using the same. The heat shrinkable film comprises a copolymerized polyester resin comprising a diol component and a dicarboxylic acid component and has a heat shrinkage rate of 30% or more in the main shrinkage direction upon thermal treatment at a temperature of 80 C. for 10 seconds and a melting point of 190 C. or higher as measured by differential scanning calorimetry. It not only solves the environmental problems by improving the recyclability of the polyester container, but also is capable of enhancing the yield and productivity.
Process for preparing polyalkenamers for packaging applications
The present invention relates to a process for producing cycloalkenamer-containing compositions and to such cycloalkenamer-containing compositions. The invention further relates to the use of these cycloalkenamer-containing compositions in the field of packaging materials, especially for food and drink.
POLYESTER CONTAINER AND MANUFACTURING METHOD THEREFOR
The present invention relates to a polyester container. The polyester container is formed from a polyester resin containing a particular content of diol moieties derived from isosorbide and diethylene glycol, and thus can show high transparency in spite of a great wall thickness thereof.
