A gas barrier film according to the present invention includes: a resin film substrate; a first layer made of an aqueous coating agent (C) that contains a water soluble polymer (A) and an inorganic layered mineral (B); and a second layer made of a coating agent (D) that contains titanium oxide, the first layer and the second layer being disposed in this order on at least one surface of the resin film substrate.

A biodegradable bioplastic may be formed from starch or cellulose. A carbohydrate may be reacted with chloroacetamide and further reacted with one or more cross-linking agents to obtain a bioplastic material. The bioplastic material may be insoluble in water, and/or hydrophobic and/or substantially transparent. The bioplastic material may be formed into numerous shapes and structures. The bioplastic material may have high toughness, flexibility and/or moldability whereby the material is suitable for further processing into a wide variety of different shapes and structures. The bioplastic material may also be utilized as a barrier or coating on paper or other substrates for food packaging and other applications.

A method for producing an electronic device and an electronic device are disclosed. In an embodiment a method for producing an electronic device includes attaching semiconductor chips on a carrier, applying a fluoropolymer to main surfaces of the semiconductor chips facing away from the carrier and a main surface of the carrier facing the semiconductor chip thereby forming an encapsulation layer including a fluoropolymer, structuring the encapsulation layer thereby forming cavities in the encapsulation layer and applying a metal layer in the cavities.

This invention relates to barrier films which are prepared from a blend of at least two high density polyethylene (hdpe) resins and a nucleating agent. The films are used to prepare packaging for dry foods such as crackers and breakfast cereals.

One of the purposes of the present invention is to provide a radiation curable organosilicon resin composition which offers a cured product having a sufficient gas barrier property and which further has workability enough for use in spin coating or inkjetting. The present invention provides a radiation curable organosilicon resin composition comprising 100 parts by mass of (A) a (meth)acryloyloxy group-containing organosilane represented by the formula (1) which has a (meth)acryloyloxy group or a monovalent organic group having 4 to 25 carbon atoms and having one, two, or three of said (meth)acryloyloxy group, and 1 to 50 parts by mass of (B) a photopolymerization initiator.

Provided is a resin composition, comprising: an isobutylene-based copolymer (A) containing a halogen atom; an ethylene-vinyl alcohol copolymer (B); and a halogen scavenger (C), wherein a mass ratio (B/A) of the ethylene-vinyl alcohol copolymer (B) to the isobutylene-based copolymer (A) containing a halogen atom is from 20/80 to 50/50, and a content of the halogen scavenger (C) is from 0.01 to 1 part by mass based on 100 parts by mass of a total of the isobutylene-based copolymer (A) containing a halogen atom and the ethylene-vinyl alcohol copolymer (B). Such a resin composition is excellent in gas barrier properties and flexibility and stably produced over a long period of time.

Barrier adhesive compositions include at least one polyisobutylene-containing polymer and a copolymeric additive that is a polyisobutylene-polysiloxane copolymer. The polyisobutylene-polysiloxane copolymers are prepared by the reaction of a hydridosilane-functional polysiloxane and an ethylenically unsaturated polyisobutylene oligomer. Barrier film articles include the barrier adhesive compositions and a film. The barrier film articles can be used to encapsulate organic electronic devices.
