Slip Agents for Package Surface Control

Compound slip agent for reducing adhesion in polyolefin films. The slip agent is a mixture of two components, slip agent A and slip agent B. Slip agent A is a specific fluorinated compound. Slip agent B is selected from polysiloxane, fatty acid secondary amide, N,N'-distearoylethylenediamine, and tetrakis[β-(3,5-di-tert-butyl pentaerythritol esters of (4-hydroxyphenyl)propionate]. The compound slip agent is used in an anti-sticking masterbatch for polyolefin films to improve slippery properties and reduce adhesion during production and storage.

A polymer composition for injection molded articles like caps and closures that balances properties like low coefficient of friction and processability without high amounts of slip agents. The composition contains a high density polyethylene (HDPE), an amide slip agent, and a polysiloxane. The amide slip agent provides initial low friction, and the polysiloxane further improves friction without needing high levels compared to just using the polysiloxane.

Coating composition with excellent applicability and coating film using the same that provides water repellency and heat resistance while enabling uniform coating over wide areas. The composition contains a polydimethylsiloxane compound, an ethoxy group penetrating component, a slip agent, a coupling agent, a heat resistance agent, and a solvent. The composition ratio ranges from 15-30 wt% polydimethylsiloxane, 5-15 wt% ethoxy group penetrating compound, 5-10 wt% slip agent, 5-10 wt% coupling agent, 3-10 wt% heat resistance agent, and the rest solvent. The coating film thickness is 0.1-5 microns.

Silicone slip agent for polyolefin films that reduces friction and avoids migration and precipitation without impacting haze and transparency. The slip agent is made by reacting maleic anhydride-grafted polyolefin with monohydroxy-terminated silicone oil. The modified polyolefin acts as the main chain with silicone segments as branches. This slip agent is used in polyolefin films to reduce friction coefficients and prevent sticking. A silicone slip masterbatch containing the slip agent, antioxidant, antistatic agent, and anti-hydrolysis stabilizer is also provided for convenient film production.

Sealant film for packaging materials that reduces lubricant bleeding, transfer, and contamination while maintaining good slipperiness regardless of storage conditions. The film has a surface layer containing a silicone lubricant and irregularities formed on the surface. The silicone lubricant is added at 0.25-3.0% by weight and the surface roughness is 1.0-4.5 μm Ra. This prevents bleeding and transfer of the lubricant while still providing good slipperiness. The irregularities on the surface prevent contamination and meandering during processing. The film also has a static friction coefficient between 0.20-0.50 after storage.

A releasing film with improved slip properties and a method for producing it. The releasing film has a coating with a specific composition of polymers, solvents, crosslinkers, additives, and slip agents to prevent blocking and improve slipping. The composition includes 3-10 parts polymer, 1.5-5 parts solvent, 0.5-1.5 parts silicone slip agent, 0.05-0.1 crosslinker, 0.03-0.06 additive, and 0.005-0.02 release agent. The coating is applied to the film using a multi-zone drying process. This composition provides a release film with controlled slip properties between adhesive and film layers to prevent blocking and adhesive transfer while maintaining adhesion.

Smoothening coating for aluminum-plastic films used in lithium-ion battery cells to improve deep drawability without migration issues. The coating contains a silica particles and a silicone resin connected by intermolecular forces. The silica particles have functional groups that react with the silicone resin's functional groups to prevent migration. This prevents migration of the slip agent into the adhesive layers and maintains coating stability. The coating reduces friction and improves deep drawing performance without affecting other film properties.

Silicone-based slip agent masterbatch for plastic films that provides excellent anti-blocking properties without issues like powdering, migration, or film degradation compared to traditional amide slip agents. The masterbatch composition contains 75-89% of a carrier resin, 5-15% of hollow glass microbeads, 2-5% of silicone powder, and 2-5% of polyethylene wax. This composition allows dispersion of the hollow glass microbeads in the resin to provide anti-blocking without migration or powdering issues. The silicone powder prevents aggregation and contamination. The polyethylene wax improves dispersion.

Sealant film for packaging materials, packaging materials, and packaging bodies with improved slipperiness stability. The sealant film contains a slip agent with a polysiloxane skeleton, diatomaceous earth with high uncalcined silica content, and a thermoplastic polyolefin resin. The slip agent content is 0.5-2.0% and the anti-blocking agent is 0.5-8.0%. This composition provides stable slipperiness without fluctuation during processing and storage. The packaging material is made by laminating a base material onto the sealed side of the film. The packaging bodies are formed by joining edges of the sealed films together.

Anti-fog coating composition for polystyrene sheets used in food packaging that provides improved stability, anti-fog, and slip properties compared to existing compositions. The composition contains fatty acid esters of sucrose, polyvinylpyrrolidone (PVP), and a specific type of polysiloxane with a viscosity of 200-500 cSt. The weight ratios between the esters, PVP, and polysiloxane are optimized for performance. This composition prevents condensation on food containers made from coated polystyrene sheets without compromising other properties like thermoformability and transparency.

Masterbatches containing functionalized silicone for improving slip properties in polyethylene compounds without migration. The masterbatches have a functionalized polysiloxane with an epoxy or secondary amine group. This reactive silicone reacts with a functionalized polyolefin containing a maleic anhydride group. The functionalized polyolefin acts as a grafting agent to immobilize the silicone in the polyethylene matrix. The non-migratory silicone provides improved slip properties compared to non-reactive silicone additives.

Slip additive masterbatches for polypropylene plastics that provide improved slip properties and migration resistance compared to traditional slip additives. The masterbatches contain a reactive silicone slip additive, a functionalized polyolefin grafting agent, and polypropylene. The functionalized polyolefin reacts with the reactive silicone to anchor it in the polypropylene matrix, preventing migration. This provides stable slip performance over time without additive transfer. The masterbatches can be let down into polypropylene resin or used directly to make articles with improved slip properties like films and laminates.
