Abstract

An air baggage tag readable by a bar code reader is composed of a recording layer, a substrate, a pressure sensitive adhesive layer, and release paper, wherein the substrate has a laminate structure composed of (A¹) a fine void-containing stretched thermoplastic resin film and (A²) a substantially void-free uniaxially stretched thermoplastic resin film having a transverse Elmendorf tear strength of at least 80 g, the thickness of the uniaxially stretched thermoplastic resin film (A²) is from 10 to 60% of the total thickness of the substrate, and the recording layer is provided on the side of the stretched thermoplastic resin film (A¹) opposite to the stretched thermoplastic resin film (A²) and has printed thereon a bar code. The baggage tag has high tear strength while exhibiting satisfactory printability and therefore, when attached to each piece of air baggage, is not easily torn apart even on being pulled.

Claims

1. An air baggage tag readable by a bar code reader which is comprised of a recording layer, a substrate, a pressure sensitive adhesive layer, and release paper, wherein said substrate has a laminate structure comprised of (A¹) a fine void-containing biaxially stretched thermoplastic resin film containing from 5 to 60% by weight of an inorganic fine powder and (A²) a substantially void-free uniaxially stretched thermoplastic resin film having a transverse Elmendorf tear strength of at least 80 g, the thickness of said uniaxially stretched thermoplastic resin film (A²) ranging from 10 to 60% of the total thickness of said substrate, with the stretching direction of said uniaxially stretched thermoplastic resin film (A²) being perpendicular to the stretching direction of the higher stretch ratio of said biaxially stretched thermoplastic resin film (A¹), and said recording layer is selected from the group consisting of a heat-sensitive recording layer, a heat transfer image-receiving layer, and a laser printing recording layer and is provided on the side of said stretched thermoplastic resin film (A¹) opposite to said stretched thermoplastic resin film (A²) and has printed thereon a bar code.

2. An air baggage tag as claimed in claim 1, wherein the thermoplastic resin of said films (A^l) and (A²) is a polyolefin resin.

3. An air baggage tag as claimed in claim 1, wherein the thermoplastic resin of said film (A¹) is a propylene resin and that of said film (A²) is a high-density polyethylene or a linear low density polyethylene.

4. An air baggage tag as claimed in claim 1, wherein said fine void-containing biaxially stretched thermoplastic resin film (A^l) has a void volume of from 10 to 60% as calculated from equation:

##EQU2## ρ

.sub. = Density of Unstretched Film ρ

=Density of Stretched, Void-Containing Film

5. An air baggage tag as claimed in claim 1, wherein said substrate (A) has a thickness of from 40 to 400 μ

m.

6. An air baggage tag as claimed in claim 5, wherein said fine void-containing biaxially stretched thermoplastic resin film (A^l) has a thickness of from 30 to 300 μ

m, and said

7. An air baggage tag readable by a bar code reader which is comprised of a recording layer, a substrate, a pressure sensitive adhesive layer, and release paper, wherein said substrate has a laminate structure comprised of (A¹) a biaxially stretched thermoplastic resin film which is comprised of (a³) a fine void-containing biaxially stretched thermoplastic resin film containing from 5 to 60% by weight of an inorganic fine powder and (a⁴) a biaxially stretched thermoplastic resin film having a smaller void volume than that of said film (a³) or containing substantially no voids and (A²) a substantially void-free uniaxially stretched thermoplastic resin film having a transverse Elmendorf tear strength of at least 80 g, the thickness of said uniaxially stretched thermoplastic resin film (A²) ranging from 10 to 60% of the total thickness of said substrate, with the stretching direction of said uniaxially stretched thermoplastic resin film (A²) being perpendicular to the stretching direction of the higher stretch ratio of said biaxially stretched thermoplastic resin film (a³), and said recording layer is selected from the group consisting of a heat-sensitive recording layer, a heat-transfer image-receiving layer, and a laser printing recording layer and is provided on the side of said stretched thermoplastic resin film (a⁴) opposite to said stretched thermoplastic resin film (a³) and has printed thereon a bar code.

8. An air baggage tag as claimed in claim 7, wherein the thermoplastic resin of said films (a³), (a⁴), and (A²) is a polyolefin resin.

9. Art air baggage tag as claimed in claim 7, wherein the thermoplastic resin of said films (a³) and (a⁴) is a propylene resin and that of said film (A²) is a high-density polyethylene or a linear low density polyethylene.

10. An air baggage tag as claimed in claim 7, wherein said fine void-containing biaxially stretched thermoplastic resin film (A^l) has a void volume of from 10 to 60% as calculated from the equation:

##EQU3## ρ

.sub. = Density of Unstretched Film ρ

=Density of Stretched, Void-Containing Film

11. An air baggage tag as claimed in claim 7, wherein said substrate has a thickness of from 40 to 400 μ

m.

12. An air baggage tag as claimed in claim 11, wherein said fine void-containing biaxially stretched thermoplastic resin film (A^l) has a thickness of from 30 to 300 μ

m, and said uniaxially stretched thermoplastic resin film (A²) has a thickness of from 10 to 100 μ

m.
