Disclosed are compositions, methods, and uses for multi-layered films which are intended to provide high quality sealants having sufficient sealing strength for use in packaging and other applications while being more cost-effective and higher-yield than traditional combinations of unoriented polyolefin films and web materials. The film comprises a multilayer structure of LLDPE having a core layer, a surface skin layer, and a sealant skin layer. The core layer further comprises a slip agent, while the skin layers further comprise antiblock agents. Optional embodiments may include tie layers between the core layer and the skin layers, or may include pigments in one or more of the core layer or tie layers. The surface skin layer may be subjected to a surface treatment (e.g., corona treatment) to improve suitability for coating or metallization.

The present invention is directed to a method of forming a laminate absorbent structure, and a resulting package containing a single continuous running web of the laminate material. Notably, formation of the material is effected by blending a curtain of adhesive fibers with a curtain of particulate material, and depositing the mixture on a moving substrate, preferably provided in the form of a tissue layer. A second substrate, also preferably comprising a tissue layer, is applied on top of the deposited mixture, and pressure applied to form the laminated structure. Notably, attendant to packaging of the laminated material, adjacent layers of the material tend to nest into one another, to form a sandwich in which the density of the material in the package is more than 1.5 times the density of the material after its removal from the package.

The present invention aims to provide an adhesive composition having excellent adhesive property and excellent anti-fogging property by way of simple and easy means such as co-extrusion with a substrate film, extrusion coating, solvent coating, etc. According to the present invention, there is provided an adhesive composition, characterized in that it contains a polyester resin (A) and an anti-fogging agent (C), and satisfies the following requirement (1): (1) Glass transition temperature of the polyester resin (A) is from −30 to 30° C.

A composite polymeric film wear layer for application as a surface protection layer to impart lower gloss, higher scratch resistance, wear performance and comfort under foot to hard surface substrates is provided. Hard surface substrate made with the composite as well as methods for application are also provided.

A composite cooling film (100) comprises an antisoiling layer (160) secured to a first major surface of a reflective microporous layer (110). The reflective microporous layer (110) comprises a first fluoropolymer and is diffusely reflective of electromagnetic radiation over a majority of wavelengths in the range of 400 to 2500 nanometers. The antisoiling layer (160) has an outwardly facing antisoiling surface (162) opposite the micro-voided polymer film. An article (1100) comprising the composite cooling film (1112) secured to a substrate (1110) is also disclosed.

The present invention provides an insulation film, comprising a film upper layer and a film lower layer, wherein both of the film upper layer and film lower layer are made of a PC or PET material, the PC or PET material contains a flame retardant to meet the flame retardance and puncture resistance property thereof; a film intermediate layer located between the film upper layer and the film lower layer, the film intermediate layer is made of the blends of PP and/or PE and PC and/or PET; an upper surface of the film intermediate layer is bound together with a lower surface of the film upper layer, a lower surface of the film intermediate layer is bound together with an upper surface of the film lower layer.
