Blow molded article with visual effects
A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.
1. A blow molded monolayer article comprising:
a. a hollow body defined by a wall comprising an inner surface and an outer surface, the wall being formed by one layer comprising:
i. one or more first regions comprising a first composition wherein the first region extends from the inner surface to the outer surface;
ii. one or more second regions comprising a second composition wherein the second region extends from the inner surface to the outer surface and wherein the second region comprises an axial color gradient;
wherein the one or more first regions and the one or more second regions form an irregular pattern on the surface of the article.
2. The blow molded article of claim 1 wherein the wall comprises a plurality of first regions and a plurality of second regions.
3. The blow molded article of claim 2 wherein the first regions and the second regions are interpenetrated.
4. The blow molded article of claim 1 wherein the first composition and the second composition comprise polyethylene terephthalate.
5. The blow molded article of claim 4 wherein the first composition and the second composition are different colors.
6. The blow molded article of claim 5 wherein the second composition comprises an effect pigment.
7. The blow molded article of claim 6 wherein the first composition is substantially free of effect pigment.
8. The blow molded article of claim 6 wherein a location of the one or more second regions comprises a surface roughness of greater than 25 μm.
9. The blow molded article of claim 1 wherein a location of the one or more first region comprises a surface roughness of less than 8 μm.
10. The blow molded article of claim 1 wherein at least a portion of the article is transparent.
11. The blow molded article of claim 1 wherein at least a portion of the article is opaque.
12. The blow molded monolayer article of claim 1 , wherein the article is a bottle.
13. The blow molded monolayer article of claim 1 , wherein the article had a Critical Normal Load greater than 50 N.
14. A blow molded multilayer article comprising:
a. a hollow body defined by a wall comprising an inner surface and an outer surface, the wall being formed by
i. a first skin layer comprising a first composition and an outer surface of the wall;
ii. a second skin layer comprising the first composition and an inner surface of the wall;
iii. a core layer comprising a second composition;
wherein the core layer, the first skin layer, or the second skin layer comprises a thickness that varies across the length of the article to form an irregular pattern that can be viewed on the surface of the article.
15. The blow molded multilayer article of claim 14 wherein the thickness of the second skin layer is varied.
16. The blow molded multilayer article of claim 15 wherein the thickness of the second skin layer decreases to substantially zero at least once across the body.
17. The blow molded multilayer article of claim 15 wherein the thickness of the second skin layer decreases but does not decrease to substantially zero at any point across the body.
18. The blow molded multilayer article of claim 15 wherein the average local wall thickness varies by less than 20% across the volume.
19. The blow molded multilayer article of claim 14 wherein at least 70% of the body comprises an opacity greater than 70%.
20. The blow molded multilayer article of claim 14 wherein the first composition and the second composition comprise polyethylene terephthalate and wherein the core layer further comprises an effect pigment.
