A method for producing a multilayer member having a first member containing a crystallizable thermoplastic resin, an adhesion layer, and a second member includes performing a dry treatment on a surface of the first member containing a crystallizable thermoplastic resin so as to satisfy conditions A and B, applying an adhesive to the surface of the first member to form an adhesive layer on the surface, and adhering the second member to the adhesive layer. (A) The ultimate temperature of the first member is lower than the peak temperature of endothermic peak obtained by DSC of the crystallizable thermoplastic resin. (B) The high temperature holding time of the first member is less than 3.0 seconds, which is when the first member is continuously held at a temperature not lower than a temperature at the starting point of the endothermic peak obtained by DSC of the crystallizable thermoplastic resin.

The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.

The invention relates to a process for the preparation of an oxygen barrier film having an oxygen barrier layer and a treated substrate, comprising the steps of: a) subjecting a polyolefin substrate to a surface treatment to obtain the treated substrate wherein the surface under the parts of the curves corresponding to the C—O, C—N and C═O groups is at least 10% based on the total surface under the curve as obtained by X-ray photoelectron spectroscopy (XPS), b) applying an aqueous or hydroalcoholic coating composition comprising 0.1 to 25 wt % of polyvinyl alcohol, 0.1 to 30 wt % of a metal alkoxide and optional silicate minerals on the treated substrate obtained by step a) and c) drying the coating composition to obtain the oxygen barrier layer resulting in the oxygen barrier film, wherein the amount of the optional silicate minerals in the coating composition is less than 10 parts by weight per 100 parts by weight of the polyvinyl alcohol in the coating composition.

Methods for forming channels within a substrate include molding a sacrificial component directly into the substrate and igniting the sacrificial component to deflagrate of the sacrificial component and form a channel in the substrate. The sacrificial component can include oxidizing agents such as chlorates, perchlorates, nitrates, dichromates, nitramides, and/or sulfates imbedded in a polymeric matrix, and the oxidizing agents can be 30 wt. % to 80 wt. % of the sacrificial component. The sacrificial component can further include one or more of unoxidized metal powder fuels, flammable gas-filled polymeric bubbles, one or more metallocenes and/or one or more metal oxide particles, one or more polymers with nitroester, nitro, azido, and/or nitramine functional groups, one or more burn rate suppressants such as oxamide, ammonium sulphate, calcium carbonate, calcium phosphate, and ammonium chloride, and non-combustible hollow bubbles and/or inert particles. The polymeric matrix can have a limiting oxygen index of less than about 30.

A method is provided for surface smoothing an additively manufactured shaped part consisting of plastic. The method has an explosion step with which the surface of the shaped part is smoothed in a process chamber by igniting a combustible process gas introduced into the process chamber, the surface of the shaped part being partly dissolved in at least some sections by the ignited process gas. Also provided is a device for surface smoothing additively manufactured shaped parts consisting of plastic.
