This disclosure provides new methods, compositions, containers, preforms, and designs for refillable carbonated soft drink bottles having improved caustic stress cracking resistance. The method of this disclosure combine the use of PET-based co-polyester resin that incorporates a cyclic hydrocarbon diacid co-monomer and/or a cyclic hydrocarbon diol comonomer, with a bottle design incorporating a petaloid base, for unexpectedly enhanced performance.

The present disclosure describes bottle closure assemblies which are made at least in part with a polyethylene composition having good processability, good organoleptic properties and good dimensional stability. The bottle closure assembly includes a cap portion, an elongated tether portion, and a retaining means portion. The retaining means portions engages a bottle neck or an upper portion of a bottle. The elongated tether portion connects at least one point on the cap portion to at least one point on the retaining means portion so as to prevent loss of the cap portion from a bottle.

The disclosure generally relates to poly alpha-1,3-glucan compositions and articles containing them. In particular interest is comprising poly alpha-1,3-glucan ester derivatives. The poly alpha-1,3-glucan derivatives are useful in thermoprocesses and in particular, injection molding processes.
