Abstract: A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.

Abstract: Holders for flat objects such as computer disks which can provide pages of a book which carries such objects, instruction for their use and etc. Each page is made of a single sheet of foldable material, preferably spunbonded olefin (such material being available from DuPont under their tradename "Tyvek"). The sheets are cut into the shape of rectangular center panels with bottom and side flaps extended therefrom; the side flaps extending from opposite side edges of the center panel and being off-set from each other. Since a single sheet is used it may be printed with visible indicia (e.g., the name of the manufacturer of and the computer program on the disks), prior to cutting, by conventional printing techniques in one pass through the press. The cut sheets (blanks) can then be manipulated in envelope manufacturing equipment which scores, applies adhesive lines and folds the flaps to provide a plurality of partially overlapping pockets, disposed one above the other.

A tube fabricated from a web is provided in the region of its longitudinal borders with two triangularly-shaped and punched cut-outs, through which there are defined subsequent separating lines for separating individual tubular pieces from the tube. One or an upper panel of the tube is obtained by two separating cuts spaced parallel from, and at a distance from one another, while the lower panel is obtained by a separating cut positioned between the afore-described separating cuts for the upper panel. The bottom closure and the closure cap of the mailing bag are formed by these cuts.

Abstract: A method for producing mass quantities of discrete envelope and letter assemblies in a continuous operation, each of which includes an envelope and a separate letter having a business-fold disposed within the envelope, both formed from the same single sheet of material, and enabling the producer to print a personalized letter upon the sheet prior to the formation of the envelope assembly. The highly desirable end result which is attained is that the completed letter is in a business-letter-fold and the sheet moves continuously forward as the assembly is formed, such that the salutory heading of the letter opens to view when the letter is withdrawn from the envelope, and the signatory panel is folded between the salutation panel and the intermediate portion of the letter. The method is capable of continuous operation inasmuch as each sheet continuously moves in the same direction throughout each of the steps of the method.
