摘要： Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The new films are compatible with known coextrusion manufacturing techniques, and can also be made without the use of adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined in such a way that delamination of the film is likely to occur along a plurality of delamination surfaces corresponding to interfaces between particular pairs of layers for which the peel strength is reduced relative to the peel strength at other layer interfaces within the film. The absence of an adhesive between peelable layer packets results in the delamination being irreversible.

摘要： Barrier assemblies including ultrathin barrier laminates and methods of making the barrier assemblies are provided. A barrier assembly includes a thermoplastic polymer skin layer having opposite first and second major surfaces, and a barrier stack coated on the first major surface of the thermoplastic polymer skin layer to form an integral protective layer having a thickness no greater than about 0.5 mil (about 12.7 microns). The removable carrier film has a major surface releasably attached to the second major surface of the thermoplastic polymer skin layer. In some cases, the removal of the carrier film results in ultrathin barrier laminates.

摘要： Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packet pairs. Some polymer layers, including at least one embedded layer, may include an ultraviolet (UV) light stabilizer such as a UV absorber, antioxidant, or hindered amine light stabilizer (HALS), and these layers may be positioned at the front of each layer packet. After the UV-stabilized layer of one packet has been used, the packet can be peeled away to expose a new UV-stabilized layer of the next layer packet.

摘要： A system comprises a slot die including an applicator slot extending about a width of the slot die, wherein the applicator slot is in fluid communication with a fluid flow path through the slot die, and a plurality of actuators spaced about the width of the slot die. Each actuator is operable to adjust a cross-directional thickness of the fluid flow path at its respective location to provide a local adjustment of fluid flow through the applicator slot. The system further comprises a controller configured to set the position of each actuator according to one of a plurality of discrete settings for operation of the slot die. The controller is further configured to predict a set of discrete settings corresponding to a preselected cross-web profile for an extrudate based on a known correlation between the set of discrete settings and the cross-web profile of the extrudate.

摘要： A feedblock including a first packet creator that forms a first packet including a first plurality of polymeric layers, the first plurality of layers including at least four first individual polymeric layers; and a second packet creator that forms a second packet including a second plurality of polymeric layers, the second plurality of layers including at least four second individual polymeric layers, wherein the first and second packet creators are configured such that, for each packet creator, respective individual polymeric layers of the plurality of polymeric layers are formed at approximately the same time. The feedblock may include a packet combiner that receives and combines the first and second primary packets to form a multilayer stream. In some examples, at least one of the first and second primary packets may be spread in the cross-web direction prior to being combined with one another.
