The present invention relates to a thermoplastic resin composition with excellent chemical resistance and, more specifically, to a resin composition for blow molding and a molded product obtained by molding the same, the composition maintaining the balance of flowability and impact resistance and improving chemical resistance by controlling the glass transition temperature (Tg) and the weight average molecular weight (Mw) of an α-methylstyrene (AMS)-based heat-resistant resin in a copolymer of vinyl cyanide compound-rubbery polymer-aromatic vinyl compound, having reinforced heat resistance, particularly, in an acrylonitrile-butadiene-styrene (ABS) copolymer resin. According to the present invention, an ABS resin composition for blow molding, having excellent chemical resistance while maintaining the balance of flowability, impact resistance and heat resistance to be of at least the same level, and a molded product obtained by applying the same can be obtained.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

A bioplastic collapsible dispensing tube may include a collapsible tube having walls that include a bioplastic material; a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the closure is opened and the tube is collapsed, flowable material inside the tube is urged out of the nozzle; and the bioplastic material includes a bio resin selected from the group consisting of PEF, PBF, PTF, GPE, GPET, PLA, PDLA, PLLA, PHA, and PHBH. A method may include forming a tube and filling the tube with flowable material from the distal end.

A preform including: an opening portion; a body portion; and a bottom portion, the preform having a two-layer structure in which the body portion and the bottom portion include an inner layer made of a virgin material and an outer layer made of a recycled material, in which a weight ratio of the recycled material to a total weight of the preform is 50% by weight or more, a ratio of a thickness of the outer layer to a thickness of the inner layer in the body portion is 1.5 or more, and a haze of a body portion of a container molded from the preform is 1.8% or less.
