A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

The present invention aims to provide an intermediate film for laminated glass which, in the case of being used for constituting a laminated glass, enables to improve the sound-insulating property of the obtained laminated glass, and a laminated glass. The intermediate film 1 for laminated glass of the present invention comprises a first layer 2 which contains a polyvinyl acetal resin and a plasticizer, and the polyvinyl acetal resin and the first plasticizer are a polyvinyl acetal resin and a first plasticizer which have a cloud point of 5° C. or lower when the cloud point is measured using a solution prepared by dissolving 8 parts by weight of the polyvinyl acetal resin in 100 parts by weight of the first plasticizer; and the laminated glass 11 of the present invention comprises first and second components for laminated glass, and the intermediate film 1 for laminated glass sandwiched between the first and second components for laminated glass.

A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25° C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.

A substrate comprising a crosslinked polymer primer layer, and grafted thereto a ligand-functionalized polymer is provided. The grafted polymer has the requisite affinity for binding neutral or negatively charged biomaterials, such as cells, cell debris, bacteria, spores, viruses, nucleic acids, and proteins, at pH's near or below the pI's of the biomaterials.

This application provides a composite film for a cable wrapping layer and a preparation method for the same. The composite film for the cable wrapping layer includes a PE film layer, a PET film layer laminated at the PE film layer, an aluminum foil layer laminated at the PET film layer, and a bonding layer arranged between the PET film layer and the aluminum foil layer. The PE film layer is made of raw materials having the following parts by weight: 40-45 parts of LLDPE with a melt index of 0.9-1.1 g/10 min and a density of 0.920-0.922 g/cm.sup.3, 35-40 parts of m-LLDPE with a melt index of 1.9-2.1 g/10 min and a density of 0.917-0.920 g/cm.sup.3 and 15-25 parts of ethylene-vinyl acetate copolymer.

The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.

Embodiments of the disclosure include lubricious coatings. In an embodiment the disclosure includes a lubricious coating for a medical device including first and second coated layers. The first coated layer is between the second coated layer and the device surface and includes a vinyl pyrrolidone polymer and a photo reactive group. The second coated layer is in direct contact with the first coated layer and is a top coating that includes an acrylic acid polymer. The second coated layer can optionally include photoreactive groups. The coating was found to have a very low number of particulates (e.g., 10 μm or greater) which is very desirable for in vivo use.

A coating liquid includes: ultrafine zinc oxide particles; a polyester resin; an ammonium polycarboxylate salt; and water, in which an amount of the ammonium polycarboxylate salt is from 1 to 35 mass % with respect to that of the ultrafine zinc oxide particles.
