A multilayer, metallized, laminate film employed to form in-mold labels, includes first and second multilayer structures adhesively bonded together. The first multilayer structure (12) includes a polymer core layer (16) and first and second outer polymer layers on opposed sides of the core layer. The first outer polymer layer (18) includes a metal layer (22) thereon, and the second polymer layer (20) having an outer matte surface that is adapted, in the in-mold label formed from laminate film, to engage and bond to a molded article. The second multilayer structure (14) is a clear structure including a core layer (16) and first (18) and second (20) outer polymer layers on opposed sides of the core layer. The bonded interface of the first and second multilayer structures is free of any printed indicia or other graphics. Preferably both outer surfaces of the film are bottom outer layers and include matte surfaces. A label in accordance with this invention is formed from the above-described laminate film by printing an outer surface of the film either before or after the film/label is printed.

The invention provides a device for connecting together two flat tubular sheaths, the device including: a blocker (22a, 22b, 22c, 22d) for blocking one end of a first sheath, the blocker having means for opening an end of the first sheath; an adhesive-applicator system for applying adhesive to the inside of the open end of the sheath; the blocker being arranged to authorize closure of the end of the first sheath, once adhesive has been applied thereto, on an end of the second sheath.

The invention also provides a corresponding roll of adhesive and a corresponding connection method.

A mold is provided having a first part and a second part, the mold being removably coupled to the molding machine. The mold first part and second part being movable between an open and closed position. An RFID module is coupled to the mold first part. An RFID reader is arranged to receive a signal from the RFID module when the mold first part is in the closed position. A controller is operably coupled to the RFID reader, wherein the controller includes a processor that is responsive for receiving an object identification data in response to the RFID reader receiving the signal from the RFID module. A printer configured to print a label including the object identification data in response to the controller receiving the signal.

A plastic injection security label and manufacturing method of the same may comprise a mold having a pair of die sets, and at least one of the two die sets has a molding cavity formed on an inner surface thereof. The surface of the molding cavity has a plurality of nicks formed by the laser engraving machine at partial positions thereof, and the engraved nicks are arranged into a designed image or code to form a label generating area on the surface of the molding cavity. In the manufacturing process, after the die sets are coupled together, the plastic material is injected into the mold and filled with the molding cavity and the nicks of the label generating area, and a plastic product with the security label is integrally formed after the plastic material is cooled and solidified.

A laminate film including at least one bio-based polyester layer. The polyester layer has a radiocarbon (.sup.14C) content of at least 21.5 pMC. The laminate film may further have additional layers such as a second bio-based polyester resin-containing layer of at least about 21.5 pMC radiocarbon content, a metal layer, or combinations thereof.

The inventive label is prepared from a polyester with an intrinsic viscosity of 0.58 dl/g or more. The label has a base film with a thickness of 8-30 m and a difference in specific heat capacity Cp between temperatures lower and higher than Tg of 0.2 J/(g.Math. C.) or more. The label has a tensile elongation at break of 5% or more in both a main shrinkage direction and an orthogonal direction. A difference between the absorbancy ratio (absorbancy at 1340 cm.sup.1/absorbancy at 1410 cm.sup.1) in the main shrinkage direction of the label and the absorbancy ratio in the direction orthogonal to the main shrinkage direction of the label is 0.2 or more. The label has a difference between a maximum value and a minimum value of a length in a vertical direction of the label of 3 mm or less.

The invention relates to a method for the extrusion and labelling of a packaging tube (14), comprising the following successive steps performed on an extrusion-labelling line, namely: a) forming a partially or fully tubular label (17) from a film (12); b) introducing the label (17) into a calibration element (22); c) extruding a tubular body (13) on the side of the concave surface of the label (17); d) bringing the external surface of the tubular body (13) into contact with the concave surface of the label (17), step (c) being performed in the calibration element (22). The invention also relates to an extrusion-labelling device and a packaging tube.
