Abstract
Coated paper for labels, specially adapted to the conditions of utilization in breweries, is fabricated by applying to one side of the fibrous label paper medium a hydrophilic coating slip having a fast reaction to water so as to accelerate the absorption of water and by applying to the other surface a coating of a composition containing a binder comprising a mixture of cross-linkable and soft latex. Strict electronic control of the moisture rate of the paper during the manufacturing process provides for a remarkable dimensional stability and an excellent inherent flatness in a relatively large moisture range.
Claims18
A method of manufacturing a coated paper suitable for use as a coated label to be applied to a bottle, said label includes a fibrous base and a first coating and a second coating, said method including the steps of:
- a. forming said fibrous base, wherein:
- 1. said fibrous base has a front face and a reverse face,
- 2. said front face is visible when said label is applied to said bottle;
- 3. said reverse face is in direct contact with said bottle when said label is applied to said bottle;
- b. applying a hydrophilic coating slip to said reverse face of said fibrous base, said hydrophilic coating slip having a rapid reaction with water to accelerate a reaction therewith as a first step in forming said coated label;
- c. applying a coating mixture to said front face of said fibrous base, said mixture comprising a cross-linkable latex and a soft latex as a second step in forming said coated label;
- d. subjecting sad coated label to at least one controlled drying-rewetting cycle to adjust a moisture content of said label to a predetermined set of characteristics;
- and
- e. recovering said label.
