The invention aims to provide automatic packaging film and a method for preparing the same. Mutually parallel adhesive areas (2) are arranged at intervals laterally on the same side of the film substrate, a non-adhesive area (1) is formed between two adhesive areas (2), and each non-adhesive area (1) and an adjacent adhesive area (2) form a packaging section; between the adjacent packaging sections, the non-adhesive area (1) of a packaging section and the adhesive area (2) of a next packaging section are connected through a separable splicing tape; all the packaging sections are connected through separable splicing tapes to form an entire continuous automatic packaging film (3). The invention solves the technical problems that the film is stuck or broken during automatic packaging, leading to machine shutdown and thus failure of automatic packaging.

Provided are an adhesive sheet including a base layer, an adhesive layer, and a release paper, which are sequentially disposed, the adhesive layer being attached to a target for attachment after the release paper is removed, wherein the adhesive layer includes a first adhesive layer, which is attached to one surface of the base layer, and second adhesive layers attached to the first adhesive layer and to the release paper, the second adhesive layers being arranged so as to form a pattern, wherein the second adhesive layers remain attached to the target for attachment, wherein a film is attached to the target for attachment without requiring the film to be wet with water, and wherein an air layer or air bubbles are discharged from the adhesive sheet through paths that serve to discharge the air bubbles, thereby preventing a reduction of initial adhesive force, solving a problem of freezing, and achieving easy attachment, and a method of manufacturing the same.

Provided is a seal-type thermal transfer image-receiving sheet capable of providing a seal section having novel designability. A seal-type thermal transfer image-receiving sheet includes a release section and a seal section integrated. The seal section is provided peelably from the release section. The seal section has a layered structure in which a pressure-adhesive layer and a receiving layer capable of receiving a sublimable dye are layered in the order mentioned from the side of the release section. When the seal section is peeled off from the release section, a reference plate and the seal section peeled off are superposed together, and a reflection density of the reference plate is measured from the side of the seal section, the value of the reflection density is 15% or more, on the presupposition that the reflection density of the reference plate before the superposition with the seal section is set to 100%.

Prepregs having a UV curable resin layer located adjacent to a thermally curable resin layer wherein the UV curable resin layer includes at least one UV cured resin portion and at least one UV uncured resin as well as methods for preparing flexible printed circuit boards using the prepregs.

Subject matter of the invention is an adhesive tape (K) for on-the-fly roll changeover of flat web material (RB) wound up into rolls (R; B), having a carrier layer (K3), which comprises a first surface (K31) and a second surface (K32) opposite the first surface (K31), a first layer of adhesive (K1), which is disposed indirectly or directly over at least part of the area on the first surface (K31) of the carrier layer (K3), a second layer of adhesive (K2), which is disposed on at least one areal region (FB) of the second surface (K32) of the carrier layer (K3), and at least one predetermined breakage area for the areal splitting of the adhesive tape (K), where the predetermined breakage area is configured such that the at least one areal region (FB) comprises a surface coating (K4), which is disposed between the carrier layer (K3) and the second layer of adhesive (K2), where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of adhesion of the surface coating (K4) to the carrier layer (K3), and/or where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of cohesion within the surface coating (K4), wherein the second layer of adhesive (K2) has a deactivated bonding region (K6) on a surface (K21) pointing in the carrier layer (K3) direction.

A removable covering for an object includes an adhered section that is adhered to the object (e.g., adhered to a receiving surface of the object via an adhesive layer) and a free section that is not adhered to the object. The removable covering is sufficiently flexible to allow at least partial removal of the adhered section from the object by application of a force to the removable covering. Typically, the removable covering is adhered to the object such that resistance to removal of the covering from the object varies at different zones of attachment between the removable covering and the object. The resistance variation may be achieved, for example, by employing tabs, loops, folds, varying-strength adhesive strips, textures and/or release coatings. Exemplary packaging systems (e.g., containing removable coverings and/or objects) include features such that resistance to removal of the packaging system from an object varies at different phases of removal.

A method of manufacturing a molded article, which comprises: (a) a step of manufacturing the molded article by use of a laminate that has a first layer comprising polypropylene, and a second layer comprising one or more selected from the group consisting of polyethylene, polyamide, an ethylene-vinyl alcohol copolymer, and an ethylene-vinyl acetate copolymer.

A transferable film includes a carrier layer and an intermediate film portion. The carrier layer is configured to receive one or more additional layers and to be releasable from the one or more additional layers temporally proximate to an application of the transferable film to an object. The intermediate film portion includes a readable conductive image portion and is configured for application thereto of an adhesive layer. The intermediate film portion is configured to be interposed between the carrier layer and the adhesive layer, and the adhesive layer configured to adhere to the object for the application of the transferable film to the object.
