Blow molded article with debossing
A blow molded multilayer article having a hollow body defined by a wall comprising at least three layers. The wall has a first Layer A comprising an outer surface of the wall, a second Layer A comprising the inner surface of the wall and a Layer B between the first and second Layer As. The B layer can contain an effect pigment and/or an opacifying pigment and the Layer As can be transparent. The wall contains a deboss element.
1. A blow molded multilayer article comprising:
a hollow body defined by a wall comprising at least three layers, a first Layer A comprising an outer surface of the wall, a second Layer A comprising the inner surface of the wall and a Layer B between the first and second Layer A;
wherein the first and second Layer A are transparent and optionally comprise a colored dye or pigment;
wherein the Layer B comprises a pigment;
wherein the first Layer A comprises a thermoplastic resin selected from a group consisting of polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polyvinylchloride (PVC), polyethylene terephthalate glycol (PETG), polystyrene (PS), and combinations thereof;
wherein the second Layer A and the Layer B comprise the same thermoplastic resin as the first Layer A;
wherein the first and second Layer A are adhered to the Layer B without visible delamination seen by a bubble-like appearance visible through the inner and outer outer surfaces of the wall;
wherein the outer surface of the wall comprises a deboss element and a non-deboss area, wherein the deboss element has a different texture as compared to the non-deboss area.
2. The article according to claim 1 , wherein the deboss element is visually perceptible.
3. The article according to claim 1 , wherein the first layer A comprises a thickness and the second layer A comprises a thickness and the thickness of the first layer A is greater than the thickness of the second layer A.
4. The article according to claim 3 , wherein the thickness of the first Layer A in the debossed area is at least 5 μm greater than the thickness of the first Layer A in the non-debossed area.
5. The article according to claim 1 , wherein the debossed element comprises a surface roughness of greater 0.5 μm.
6. The article according to claim 1 , wherein the Layer B in the deboss element comprises a thickness from about 20 μm to about 300 μm.
7. The article according to claim 1 , wherein at least 30% of the article outside the deboss element comprises a gloss 20° of greater than or equal to 65 GUs.
8. The article according to claim 1 , wherein the first and second Layer A are adhered to the Layer B without adhesive.
9. The article according to claim 1 , wherein the Layer B comprises from about 0.01% to about 5%, by weight of the Layer B, pigment and wherein the pigment is an effect pigment comprising platelet-like pigments with a face wherein the pigments are primarily oriented so that the face is parallel to the outer surface of the article.
10. The article according to claim 1 , wherein the article has a non-cylindrical shape.
11. The article according to claim 1 , wherein the article comprises a location on the outer surface with a haze of less than 20.
12. The article according to claim 1 , wherein the article comprises a location on the outer surface with a haze anisotropy of less than or equal to 0.9.
13. The article according to claim 1 wherein the Layer B is opaque.
14. The blow molded multilayer article of claim 1 , wherein the wall further comprises:
an interface region between the first Layer A and Layer B where Layer A and Layer B are interpenetrated with each other.
15. The article according to claim 14 , wherein a wall in the region where the three layers are present comprises a Critical Normal Load greater than 30 N.
16. The article according to claim 14 , wherein the wall at the non-deboss area and the wall at the deboss element comprise a thickness; and
wherein the thickness of the wall at the deboss element is greater than the thickness of the wall at the non-deboss area.
17. The article according to claim 1 , wherein the thermoplastic resin consists of polyethylene terephthalate.
18. The article according to claim 1 , wherein the B Layer extends across the entire wall.
19. The article according to claim 1 , wherein the deboss element comprises a matte or rough texture and the non-deboss area comprises a high gloss texture.
20. The article according to claim 1 , wherein the roughness ratio on the outer surface between the deboss element and the non-debossed area of the article is greater than 15.
