Antistatic Agents for Static-Free Packaging

A method for manufacturing a recyclable and moisture-proof packaging strip that is easy to recycle, has water repellency, low adhesion, and anti-static properties, and is environmentally friendly and moisture-proof. The method involves forming a double coating layer on the inner surface of the paper fabric constituting the packaging strip. The first coating layer is made with an acrylic resin composition. The second coating layer is made with modified calcium carbonate. This provides water repellency, low adhesion, and anti-static properties. The paper fabric with the double coating layer is overlapped and bonded to create a barrel-shaped packaging strip. This eliminates the need for synthetic resin films that can't be easily recycled.

Packaging material with reduced static electricity that can be manufactured using a gravure printing process. The material has an antistatic coating layer formed on a multilayer film using an antistatic treatment solution mixed with ethanol. The coating is applied by gravure printing and then dried. The antistatic coating contains polyurethane resin, conductive polymer, surfactant, crosslinker, and fluororesin. Ethanol improves coating properties, speed, and safety. The antistatic coating reduces friction static electricity to prevent contents from sticking to the packaging.

Heat seal sheet and sterilization package with improved peelability and reduced dust scattering during opening, particularly useful in medical settings where sterile objects are stored. The heat seal sheet has a thermoplastic adhesive layer with an antistatic agent to reduce static cling and improve peelability. The sheet also has low air permeability to prevent lint scattering. The antistatic agent is contained in an amount of 0.5-20 parts by mass relative to 100 parts of the thermoplastic resin. The sheet can be used to seal sterilization packages, with thermally sealed portions having a 180° peel strength of 0.5-15 N/15 mm when opened at 300 mm/min. This provides easy peelability without excessive force that could damage sterilized contents.

Laminate with improved adhesion properties when used with substrates containing antistatic agents. The laminate has three layers: a barrier layer, a resin layer, and a substrate layer. The resin layer contains a specific copolymer with ethylene and a dicarboxylic anhydride monomer. This copolymer provides good adhesion to the barrier layer and substrate layer even when the substrate contains an antistatic agent. The barrier layer has low oxygen permeability. The laminate can be used in packaging applications where the substrate contains antistatic agents.

Cover tape for packaging electronic components that has high antistatic performance and allows easy peeling of end tape. The cover tape has layers in order: antistatic, base, intermediate, and heat seal. The antistatic layer has a surface resistivity of 1x10^10 ohms. The peel strength of an end tape attached to the antistatic layer is 2 N or less after storage at 40°C, 90% RH. The peel strength of the heat seal layer from the carrier tape is 0.15 N or more after storage at 40°C, 90% RH, with 125 kN/m pressure. This prevents tape delamination during device mounting. The antistatic layer contains a polyetheramine surfactant or long-chain alkyl group polymer that migrates to the surface. This compet

Cover tape for packaging electronic components that reduces abnormal behavior of electronic components when peeled off from the carrier tape. The cover tape has a heat sealing layer containing an ethylene-vinyl acetate copolymer and a polyethylene resin, and an antistatic layer. The ethylene-vinyl acetate copolymer reduces initial tackiness compared to pure ethylene resin. The polyethylene resin improves seal strength and durability in high humidity environments. The antistatic layer prevents static buildup. This reduces component adhesion when peeling the cover tape.

Mono-material laminate for food packaging that prevents dust and contents adhesion to the seal area. The laminate has a stretched polyethylene base layer and a sealant layer with an antistatic polyethylene layer on one surface. The antistatic polyethylene layer contains polyethylene and an antistatic agent. This layer prevents dust and contents from sticking to the seal area during production and filling. The antistatic agent improves the seal strength after heat sealing. The laminate is useful for mono-material packaging like pouches where adhesion issues can reduce seal integrity.

A storage container for blister packaging machines that reduces drug dust and prevents medication mixing by dissipating electrostatic charges. The container has an electrically conductive singulating device that separates drug portions. A conductor device connects the singulating device to a contact that dissipates charges. This allows charges to be transferred to the machine rather than accumulating on the container or singulating device.

Manufacturing method for aluminum vacuum packaging material that has both rust prevention and antistatic properties. The method involves mixing rust inhibiting agents like calcium benzoate, potassium sorbate, sodium caprylate, glyceryl monostearate, zinc oxide, and silicon dioxide to create a vaporizable rust preventive agent. This agent is then mixed with polyethylene wax and sprayed between the aluminum foil and sack during packaging. The wax coating prevents rusting of the packaged metal objects and also reduces static electricity compared to conventional aluminum packaging.

Antistatic packaging material that reduces costs and improves durability compared to electroplated antistatic packaging. The antistatic layer is formed directly on the packaging substrate using a graphite antistatic agent instead of electroplating and coating with an antistatic liquid. This eliminates the need for complex equipment, reduces processing time, and lowers costs. The graphite antistatic layer has better antistatic properties and longevity compared to electroplated antistatic coatings, improving competitiveness.

The cover tape has a heat seal layer with an ethylene-vinyl acetate copolymer and a polyethylene resin. The ethylene-vinyl acetate copolymer provides good heat sealability, while the polyethylene resin reduces tackiness. This combination suppresses adhesion of components and deterioration after storage in humid heat. An antistatic layer on the opposite side prevents static cling.

Cover tape for electronic component packaging that reduces adhesion of components when exposed to high temperature and humidity. The cover tape has an antistatic layer on the substrate side opposite the heat-sealing layer. After damp heat aging, the antistatic layer's surface resistivity is 1x10^10 ohms or less. The heat-sealing layer's adhesion force after damp heat is 5 grams-force or less. This prevents component sticking when the packaged electronic components are exposed to high temp, high humidity environments. The antistatic layer protects the heat-sealing layer from moisture absorption, maintaining adhesion while suppressing static.
