PACKING FROM BIAXIAL OF ORIENTATIONS POLYOLEFIN FOIL

Packaging material made of a biaxially oriented polyolefin film

VERPACKUNG AUS BIAXIAL ORIENTIERTER POLYOLEFINFOLIE

PACKAGING MATERIAL MADE OF A BIAXIALLY ORIENTED POLYOLEFIN FILM

The invention relates to a packaging material made of a multilayer oriented polyolefin film, which comprises a base layer and at least one first outer layer, whereby the first outer layer is placed in contact with itself or in contact with the opposing surface of the film or in contact with the surface of another film. This first outer layer contains an additive which absorbs light within the wavelength range of a laser such that when the film is locally irradiated by the laser, the area of irradiation experiences an increase in temperature that causes the polyolefin of the first outer layer to soften or melt in the irradiated area and to bond to another layer when cooled. © KIPO & WIPO 2007 ...

Vending system for shop or supermarket using chip cards as tokens has slot to receive card with magnetic strip with message recorded by computer

The chip token card (8) has a multilayer structure with a magnetic strip (34) for recorded data. The data may be produced by a computer. The token card may be inserted in a slit in the housing of an automatic vending machine. The machine has a price display and compartments for merchandise. The compartments are in a box with a transparent front panel. Dispensing of items may alter the credit reading recorded on the magnetic strip on the card.

THE PACKAGING MADE FROM A BIAXIAL ORIENTED POLYOLEFINE FILM.

Empaque elaborado de una película de poliolefina orientada de capas múltiples que comprende una capa base y al menos una primera capa exterior que contiene un aditivo que dentro de la escala de longitud de onda de un láser muestra tal absorción de luz, que cuando la película se irradia localmente mediante un láser, el área de irradiación experimenta tal incremento de temperatura en el área irradiada que provoca que la poliolefina de la primera capa exterior se ablande o funda en esta en la zona de irradiación y se una a otra capa cuando se enfría, caracterizado porque el aditivo está contenido en una cantidad de 0, 01 a 10% en peso, respecto al peso de la primera capa, y el diámetro medio de partícula es de 0, 01 a 4 ìm. Package made of a multilayer oriented polyolefin film comprising a base layer and at least a first outer layer containing an additive that within the wavelength scale of a laser shows such light absorption, that when the film is irradiates locally by means of a laser, the irradiation area experiences such an increase in temperature in the irradiated area that causes the polyolefin of the first outer layer to soften or melt therein in the irradiation zone and join to another layer when it cools, characterized in that the additive is contained in an amount of 0.01 to 10% by weight, based on the weight of the first layer, and the average particle diameter is 0.01 to 4 µm.

Packaging material comprising a multilayered oriented polyolefin film and process for production the same

It is described a packaging material comprising a multilayered oriented polyolefin film, which includes a base layer and at least one first outer layer, whereby the first outer layer is placed in contact with itself or in contact with the opposing surface of the film or in contact with the surface of another film. This first outer layer contains an additive which absorbs light within the wavelength range of a laser such that when the film is locally irradiated by the laser, the area of irradiation experiences an increase in temperature that causes the polyolefin of the first outer layer to soften or melt in the irradiated area and to bond to another layer when cooled. And it is described a process for the production of packing material.
