摘要： The invention relates to a self-adhesive label comprising a bilayer comprising at least one layer of paper coupled to at least one polymeric film, wherein the polymeric film is coated, on the surface opposite to the surface of coupling to the at least one paper layer, with a layer of pressure sensitive adhesive (PSA), wherein the adhesive can have "wash-off" properties such as to cause a label to peel off from a surface by washing with a 1.0%-2.0% NaOH solution at 65-75°C according to the FTM26 method, or according to the QT 500 or QT 508 protocols, published by EPBP; or the adhesive has a force lower than the shrink force of the polymeric film. The label also comprises an intermediate layer placed between the polymeric film and the PSA adhesive, capable of promoting the adhesion of the PSA adhesive to the polymeric film, and/or the polymeric film is treated with a corona treatment, a flame treatment or a plasma treatment, on the surface opposite to the surface of coupling to the at least one paper layer.

摘要： The invention features a reinforcement element including a continuous paper strip having a first side and a second side, a first adhesive composition disposed on at least one of the first side and second side. The invention further features a paper reinforced tape including a continuous paper strip, a continuous paper backing layer and a first adhesive composition disposed between the continuous paper strip and the continuous paper backing layer thereby adhering the continuous paper strip to the continuous paper backing layer. The paper reinforced tapes and reinforcement elements of this invention have improved repulpability, recyclability, compostability and biodegradability. Further, these reinforcement elements and paper reinforced tapes, despite being predominately paper, unexpectedly provide excellent container reinforcement properties and further can be used as opening tapes, dosing tapes and carrying handles.

摘要： A biodegradable display protector comprises a top layer; an antimicrobial (AF) layer beneath the top layer; a core layer formed of biodegradable material beneath the AF layer; an adhesive layer beneath the core layer; and a bottom release layer beneath the adhesive layer. The bottom release layer may be peeled off to allow the screen protector to be adhered to a display screen. In the embodiments, biodegradable polyethylene terephthalate (PET) or biodegradable polylactic acid (PLA) may be used for an inflexible protector whereas biodegradable thermoplastic urethane (TPU) may be used for a flexible protector. A thickness of the screen protector may be between about 0.08mm to about 0.23mm.

摘要： A DWR heat transfer label is provided for application to an item or fabric that is a durable water repellent (DWR) based substrate. The heat transfer label includes a carrier web, one or more ink layers that define a graphic supported on the carrier web, and at least one adhesive layer adapted to bond to the DWR substrate that is based on an acrylic or urethane composition devoid of polyester and polyamide. The DWR heat transfer label may be applied to a substrate by a heat transfer method. An adhesive formulation based on an acrylic composition is also disclosed.
