The container for packing which is produced from method and the laminated wood for packing which produce the laminated wood for packing whose characteristic is good just

摘要

The disclosure relates to a method of producing a well-integrated packaging laminate (10) comprising adjacent layers (13, 14, 15) of mutually incompatible plastics. The plastic layers (13, 14, 15) are extruded at the same time as a gaseous medium is applied, for adhesion-promoting purposes, between the extruded plastic layers. The gaseous medium may be one gas or a mixture of gases with an ability to modify or activate the counter-facing surfaces of the adjacent plastic layers in such a manner and to such an extent that the plastic layers (13, 14, 15) will be sufficiently compatible to be able to be permanently united to one another, without the need to employ interjacent layers of chemical bonding or adhesive agents. Preferably, the gaseous medium consists of ozone which is injected or aspirated in between the plastic layers (13, 14, 15) when these are extruded.
