Abstract
A decorative corrugated paper product having a preprinted and/or decorated transparent plastic film adhesively applied to at least one side of facing sheet, the other side of which is adapted for subsequent adhesion to a fluted corrugated medium in the preparation of the corrugated product, wherein the printing and/or decoration is visable through the plastic film on the exterior of the facing sheet.
Claims14
A decorative preprinted corrugated paperboard product comprising:
- a fluted paperboard corrugated medium and at least one paperboard facing sheet adhesively attached thereto;
- said one paperboard facing sheet comprising a single sheet containing two surfaces, with a first inner surface adhesively bonded to the fluted paperboard corrugated medium and a second outer surface adhesively bonded to a reverse printed plastic film.
A method of producing a preprinted corrugated paper product suitable for use as a packaging material containing the steps of:
- (1) preparing a paper facing sheet for use in the preparation of a corrugated paper product, said facing sheet comprising a single sheet containing two sides, at least one of said paperboard sides having adhesively bonded thereto a transparent reverse printed, plastic film, wherein the printing is visible through the plastic film when the film is adhered to first side of said facing sheet;
- (2) preparing a fluted corrugated medium having two sides;
- (3) adhesively attaching the tips of the flutes on one side of the fluted corrugating medium to the second of the sides of the facing sheet, so as to form a preprinted corrugated product.
A decorative preprinted corrugated paperboard product made of a plurality of preselected paperboard components and having a greater strength than a product made from the same preselected paperboard components comprising:
- a fluted paperboard corrugated medium of preselected caliper and basis weight and at least one paperboard facing sheet having a preselected caliper and basis weight adhesively attached thereto, said one paperboard facing sheet comprising a single sheet containing two surfaces, a first inner surface being adhesively bonded to the fluted paperboard corrugated medium and a second outer surface containing a reverse printed plastic film adhesively bonded to the said second outer surface of the paperboard facing sheet so as to form a said decorative corrugated paperboard product capable of being used as a preprinted packaging material without further printing.
A method of producing a preprinted corrugated paper product suitable for use as a packaging material containing the steps of:
- 1. preparing a paper facing sheet for use in the preparation of a corrugated paper product, said paper facing sheet comprising a single sheet containing two sides, at least one of said sides having adhesively bonded therto a transparent reverse printed, plastic film, wherein the printing is visible through the plastic film when the film is adhered to first side of said facing sheet;
- 2. preparing a fluted corrugated medium having two sides;
- 3. adhesively attaching the tips of the flutes on one side of the fluted corrugated medium to the second of the sides of the facing sheet, so as to form a preprinted corrugated product;
- and
- 4. affixing a second paper facing sheet to the tips of the flutes on the other side of the fluted corrugated medium to thereby form a double faced corrugated paper product having printing visible on one face and not requiring further printing.
