Abstract
A blow molded article, a method of making a blow molded article and a method of making a preform each having at least one layer comprising a thermoplastic resin and between 0.1% and 20% of an additive having a viscosity of greater than 1,000,000 cst. There is a refractive index difference of at least 0.04 between the additive and the thermoplastic resin. The high viscosity of the additive ensures even distribution of the additive within the thermoplastic resin in discrete domains, while additionally providing for a complex end look balancing opacity, gloss and depth.
Claims18
An injection stretched blow molded bottle with an improved visual effect comprising a neck and a body wherein the body comprises at least one layer comprising:
- a. more than 50 wt. % of a first thermoplastic resin selected from the group consisting of polyethylene terephthalate (PET), polyethylene terephthalate glycol (PETG), polyethylene naphthalate (PEN), post-consumer recycled polyethylene terephthalate (PCRPET), and combinations thereof;
- b. between about 0.1 wt. % and about 20 wt. % of a second thermoplastic material comprising a viscosity of from about 2,500,000 to about 50,000,000 cst;
- wherein the second thermoplastic material is immiscible or partially miscible with the first thermoplastic material;
- c. between about 10 to about 1000 discrete domains of the second thermoplastic material per 1000 μm3 of the at least one layer, wherein the discrete domains are dispersed throughout the at least one layer;
- wherein the domains comprise a length, a width, and a thickness and wherein the domains are considerably longer than they are thick and/or wide;
- wherein there is a refractive index difference of at least about 0.04 between the additive and the thermoplastic resin;
- wherein the body further comprises a high gloss outer surface.
