Layers of a recyclable packaging material can include a first layer of, or including, oriented polyethylene; a second layer of, or including, oriented polyethylene; a tie layer disposed between and joining the first layer and the second layer to one another; an ink layer printed onto at least a portion of at least one of an inner surface of the first layer or an outer surface of the first layer; a metallic barrier layer on at least a portion of at least one of the first and second layers; and an adhesive layer on at least a portion of an outer surface of the second layer and at least partially defining an exterior surface of the recyclable packaging material. A cold seal release coating can be on at least a portion of at least one of the ink layer or the outer surface of the first layer.

A method of forming a flexible packaging film includes providing a first web including a polymer sealant layer, the first web having a first major surface and a second major surface opposite the first major surface. A second web including a polymer outer layer is provided, the second web having a third major surface and a fourth major surface opposite the third major surface. An adhesive layer is applied to the second major surface and the first web is laminated to the third major surface. Prior to laminating the first web to the second web, one or more slits are formed in the second web.

The invention concerns a linerless self-adhesive material obtained starting from a self-adhesive material with a liner, by means of a process that comprises the delamination of the liner from a self-adhesive layer, activation of the liner or self-adhesive layer, transferral of the liner over the self-adhesive layer and re-lamination of the two components so as to produce the linerless self-adhesive material. The liner or the self-adhesive layer is coated with a thermo-adhesive that allows for permanent lamination of the liner located on the self-adhesive layer.

A system for protecting a surface of a substrate includes a protective film, which is configured to be applied and secured to the surface, as well as a backing on an adherent surface of the protective film and an application tape over an exterior surface of the protective film. Protruding features, such as tabs, adjacent to different peripheral edges of the protective film may enable removal of the backing and the application tape from the protective film, and may include features that indicate the order in which each protruding feature is to be grasped to peel its corresponding element away from the protective film. Methods of using such a system are also disclosed.

A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The sheet separation device includes a winding roller and a gripper. The winding roller rotates and winds the two-ply sheet to separate the two-ply sheet. The gripper is disposed in the winding roller and configured to grip a gripped portion of the two-ply sheet at one end of the two-ply sheet without abutting a tip of the gripped portion at the one end of the two-ply sheet on a member.

A solar panel disassembling apparatus for disassembling a solar panel including a glass plate and a stacked film, includes a supporting plate of which is in contact with the glass plate, a moving scraper module including a first body moving in parallel with the supporting plate, a first elevator moving vertically, and a blade connected to the first elevator and changing in height and scraping the stacked film using the blade, and a moving pressing module including a second body moving in parallel with the supporting plate, a second elevator vertically, and a pressing unit connected to the second elevator and changing in height. The moving pressing module is disposed forward in the forward movement direction of the moving scraper module and presses and aligns the stacked film using the pressing unit ahead of the moving scraper module.

A solar module exterior disassembling apparatus for disassembling an exterior of a solar module including a module body, a frame and a junction box attached to the module body includes a positioning plate supporting one surface of the module body from below the solar module and being able to move up and down, a top contact plate over the positioning plate and in contact with the other surface of the module body when the positioning plate is moved up, frame separation blades around the top contact plate and moving in parallel with a surface of the module body between a first position inside the frame and a second position outside the frame, and a pressing actuator including pressing cylinders and pressing outward from the module body and disassembling the module body by moving forward the frame separation blades from the first position to the second position with the pressing cylinders.

Disclosed herein is an intrinsically self-healing composite based upon in situ thermal remendability of an embedded polymeric interphase. The fiber-reinforced composite (FRC) material may incorporate a thermoset polymer with a defined glass transition temperature (T.sub.g) and/or a thermoplastic material of amorphous or semi-crystalline nature. The polymeric interphase can be incorporated as a plurality of particles, fibers, meshes, films, or 3D-printed structures. The self-healing composite includes a resistive heating component as a structural element that minimizes electrical energy demand and impact on mechanical integrity. Healing occurs in situ via resistive heating and can be enabled below, at, or above the glass-transition temperature of the FRC matrix, demonstrating viability for in-service repair under sustained loads. In addition to providing rapid healing functionality, the polymeric interphase increases inherent resistance to interlaminar fracture. Repeated heal cycles have been achieved in a double cantilever beam (DCB) fracture test without significant degradation in performance.
