A barrier film composition can comprise a thermoplastic web comprising a thermoplastic polymer and a dispersed cyclodextrin composition having substituents that compatibilize the cyclodextrin in the film. The thermoplastic / cyclodextrin film obtains substantial barrier properties from the interaction between the substituted cyclodextrin in the film material with a permeant. The substituents on the cyclodextrin molecule causes the cyclodextrin to be dispersible and stable in the film material resulting in an extrudable thermoplastic. Such materials can be used as a single layer film material, a multilayer film material which can be coated or uncoated and can be used in structural materials wherein the thermoplastic is of substantial thickness resulting in structural stiffness. The cooperation between the cyclodextrin and the thermoplastic polymer provides barrier properties to a web wherein a permeant can be complexed or entrapped by the cyclodextrin compound and held within the film preventing the permeant from passing through the film into the interior of a film, an enclosure or container. The permeant can comprise a variety of well known materials such as moisture, aliphatic or aromatic hydrocarbons, monomer materials, off flavors, toxic compounds etc.

The invention discloses a thermoset high-flame-retardant lusterless ink used for a PET substrate. The ink is prepared by mixing a phosphorus-nitrogen containing flame retardant, a silicone-modified polyester resin, and delustering powder with a part of diluent, performing high-speed dispersion for 20-50 min; adding a leveling agent and an antifoaming agent, and performing low-speed dispersion for 5-15 min to obtain a main agent; adding an isocyanate curing agent and the left diluent into the main agent; and performing uniform stirring to obtain the thermoset high-flame-retardant lusterless ink. The ink is good in mechanical properties, flame retardance, heat resistance and solvent resistance, is good in adhesion to the substrate and small in environmental pollution and doesn't affect the appearance of the PET substrate. The ink is reasonable in composition, good in component coordination and excellent in overall performance.

The invention discloses a heat-resistant holographic anti-counterfeiting film, which is a layered structure, which sequentially includes a carrier layer, an anti-counterfeiting information layer, a release layer and an adhesive layer from outside to inside, and the carrier layer is polyethylene terephthalate film, the anti-counterfeiting information layer is a curable heat-resistant acrylic resin layer, nano-scale fumed silicon dioxide is added to the curable heat-resistant acrylic resin, the anti-counterfeiting information layer has a concave-convex holographic pattern, and the release film The first layer is a fluorine-containing coating, and the adhesive layer is a hot-melt adhesive layer or a pressure-sensitive adhesive layer. The anti-counterfeiting information layer of the heat-resistant holographic anti-counterfeiting film of the present invention adopts a heat-resistant acrylic resin layer added with nano-scale fumed silica, which can withstand a molding temperature above 260°C and has good transparency. The existence of the release layer makes the anti-counterfeiting information The layer can be easily peeled off from the molded plate after molding to ensure the integrity and high clarity of the anti-counterfeit information, and the anti-counterfeit information layer is cured after the film is pressed, which further improves the stability of the holographic pattern.

The invention relates to a transparent halogen-free flame-retardant polycarbonate resin. The resin comprises the following components in percentage by weight: 98.4-99.75% of flame-retardant master batches, 0.05-0.6% of a fire retardant, 0.1-0.5% of an antioxidant and 0.1-0.5% of a lubricant. The preparation method comprises the following steps: preparing materials according to the components, adding PC, the fire retardant, the antioxidant and the lubricant in percentage by weight into a high-speed mixing machine, sufficiently mixing the PC, the fire retardant, the antioxidant and the lubricant, and placing the PC, the fire retardant, the antioxidant and the lubricant, which are mixed, into a screw rod machine for extruding and pelleting so as to obtain flame-retardant master batches; adding the flame-retardant master batches and the rest of the components into the high-speed mixing machine together, sufficiently mixing the flame-retardant master batches and the rest of the components, and then placing the flame-retardant master batches and the rest of the components, which are sufficiently mixed, into the screw rod machine for extruding and pelleting so as to obtain products. Compared with the prior art, the method disclosed by the invention fully uses phenyl butyl sulfonic acid potassium as the fire retardant, after the fire retardant, the antioxidant, the lubricant and the flame-retardant master batches are mixed, extruded and pelleted, the whole preparation technology is simple, a complex ladder temperature control step is not needed, the obtained products have the characteristics of transparence, thin walls, high impact strength, excellent flame retardant property, zero toxicity and zero harm, and the application range is wide.
