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.

Cover tape for packaging electronic components that reduces abnormal behavior like sticking and warping when peeled off from the carrier tape. The cover tape has a thickness range for the antistatic layer that prevents debris accumulation. When tested with steel wool, the surface resistance change ratio R1 should be between 10 and 1000. This prevents debris buildup during peeling that can cause component issues. The tape also has a heat sealing layer and base material. The thickness of the base material prevents excessive rigidity. The tape is used to cover electronic component storage areas on carrier tapes during packaging.

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 provides improved visibility of the components when peeled off for mounting. The cover tape has a specific heat transition behavior measured by DSC. It has a peak in the range of 100-103°C when heated and cooled.
