Abstract
A packing for a flat, rectangular product includes a wrapper sheet surrounding the product at its large faces to form a sleeve which has face-to-face arranged end portions sealed together adjacent a longitudinal packing edge to form a fin seal. The end portions form, beyond the fin seal, an inner and an outer longitudinal panel. The wrapper sheet further has two opposite end closure flaps folded, from opposite longitudinal ends of the product, onto the sleeve on one of the large faces of the product, and the panels are folded onto the sleeve on the large face. The outer panel projects beyond the inner panel and covers the end closure flaps. A securing arrangement attaches the outer panel to the sleeve on the large face of the product.

In a packing for a flat, rectangular product having opposite large faces each having a length and a width, including a wrapper sheet surrounding the product at the large faces to form a sleeve and having face-to-face arranged end portions sealed together adjacent a longitudinal packing edge to form a fin seal;
- said end portions forming, beyond the fin seal, two longitudinal panels;
- the wrapper sheet further having two opposite end closure flaps folded, from opposite longitudinal ends of the product, onto the sleeve on one of the large faces, and said panels being folded onto the sleeve on said one large face;
- one of said panels being an inner panel and the other panel being an outer panel;
- the inner panel being closer to the product then the outer panel;
- the improvement wherein said outer panel projects beyond said inner panel and covers said end closure flaps;
- further comprising securing means to attach said outer panel to said sleeve on said one large face.
A method of packaging a flat, rectangular product having parallel long sides, parallel short sides and opposite large faces;
- comprising the following steps:
- (a) wrapping a wrapper sheet about the product;
- (b) forming a longitudinal fin seal adjacent a long side by sealing together superposed wrapper sheet portions;
- said portions constitute, beyond said fin seal, superposed longitudinal inner and outer panels;
- said outer panel projecting beyond a longitudinal outer terminal edge of said inner panel;
- (c) folding said superposed panels as a unit into an oblique orientation with respect to said large faces;
- (d) partially folding-in and subsequently sealing end closure flaps constituting portions of the wrapper sheet projecting beyond opposite length boundaries of the product;
- (e) providing said outer panel with an adhesive;
- (f) folding and pressing said end closure flaps flat onto one of said large faces;
- and
- (g) folding and pressing said inner and outer panels flat onto said one large face.
