Provided is a heat-shrinkable multilayer film having high strength and excellent followability to its contents.

The heat-shrinkable multilayer film according to the present invention is composed of at least three layers of a surface layer (a) including a thermoplastic resin; an intermediate layer (b) including a polyamide-based resin; and a surface layer (c) including a sealable resin. (A) The load per unit width at 10% elongation is 0.70 N/mm or less in both a longitudinal direction (MD) and a transverse direction (TD) in a tensile test at 90° C. (B) The puncture strength per unit thickness is 0.200 N/μm or greater.

A gas barrier film includes a resin substrate and an oxygen barrier coating film in contact with a first surface of the resin substrate. The resin substrate includes two or more resin layers including a base layer. Of the two or more resin layers, a resin layer forming the first surface of the resin substrate does not contain an anti-blocking agent.

In the case of a film (1) from which packaging (2) can be manufactured, in particular for foodstuffs (3), optical glasses (4), individual parts for bioreactors, solar panels or the like, medical devices, pharmaceutical products or the like, the film (1) consists of at least two polymer layers which are joined together in a co-extension die (7) to form the film (1), the film (1) should already have a sterile or at least particle-free surface during the manufacturing process, which surface is reliably protected against contamination of all kinds during the transport and storage times of the film (1). This is achieved in that an additive (8) is present in one of the layers in a dosable amount and/or in that the material pairing between the first and second layers (5.sub.1, 6.sub.1) has a low adhesion force, and in that the first and second layers (5.sub.1, 6.sub.1) can be non-destructively detached from one another in a separating plane (15), in such a way that the film (1) can be divided into two film webs (11, 12).

Methods for producing layered structures that include a conductive polymeric layer and a dielectric polymeric layer. The dielectric polymeric layer can be formed by curing a first volume of a dielectric polymeric material. A second volume of the dielectric polymeric material is doped with conductive particulates to yield a conductive polymeric material, which is then partially cured and solvated to create a conductive polymeric paste. The paste is applied to a surface of the dielectric polymeric layer, dried, and cured to form a conductive polymeric layer on the pre-strained dielectric polymeric layer yielding a layered structure that includes the conductive polymeric layer and the dielectric polymeric layer. A pre-strain is induced in the dielectric polymeric material by contacting a chemical thereto that causes swelling therein.

A three-dimensional lattice architecture with a thickness hierarchy includes a first surface and a second surface separated from each other with a distance therebetween defining a thickness of the three-dimensional lattice architecture; a plurality of angled struts extending along a plurality of directions between the first surface and the second surface; a plurality of nodes connecting the plurality of angled struts with one another forming a plurality of unit cells. At least a portion of the plurality of angled struts are internally terminated along the thickness direction of the lattice structure and providing a plurality of internal degrees of freedom towards the first or second surface of the lattice architecture.

Biodegradable layered composite comprising a first nonwoven biodegradable layer having a first and second major surface, the first nonwoven biodegradable layer comprising biodegradable polymeric melt-blown fibers, and a plurality of particles enmeshed in the biodegradable polymeric melt-blown fibers; and a biodegradable polymer film on at least a portion of the first major surface of the first nonwoven biodegradable layer. Biodegradable layered composite described herein can be used, for example, as biomulch for controlling weed growth and moisture.
