LAMINADO DE ACONDICIONAMENTO, MÉTODO DE PRODUÇÃO DO MESMO, E, RECIPIENTE DE ACONDICIONAMENTO.

摘要

A packaging laminate for a thin-walled packaging container for liquid dairy produce. The laminate (11) includes a thin layer (11) of paper or paperboard and outer, liquid-tight polyolefin coatings (12, 13) of which one (12) contains light -absorbing carbon particles in sufficient quantity to impart to the container adequate tightness properties against light, in particular UV radiation. The particle-containing coating (12) is laminated to the paper- or paperboard layer (11) by means of an extruded lamination layer (14) of polyolefin. To conceal the particle-containing coating (12) and making it invisible through the paper- or paperboard layer (11), the paper- or paperboard layer (11) contains light-reflecting particles, preferably titanium dioxide particles, spread throughout the bulk of the paper- or paperboard layer (11). The quantity of light -reflecting particles in the paper- or paperboard layer (11) lies between 7 and 20 weight%, counted on the total weight of the paper- or paperboard layer (11).
