Slip

PTMB slip masterbatches are used to enhance the smoothness of films by reducing the tackiness to sliding over itself or parts of converting equipment with reduction of film coefficient of friction. It functions by migrating to the surface and forming a lubrication layer on it with no adverse effect on the printing and sealing properties.

Key benefits

  • No effects on the printing and sealing properties.
  • Enhances the smoothness of films.
  • Forms a lubrication layer on the film.
  • Overcomes film tackiness.
  • Improve film machinability in FFS Lines.
  • Reduce Film-To-Film Adhesion.
  • Reduce Film-To-Metal Adhesion.
  • Designed reduction of COF from 1.0 to 0.20.
  • Improve Extruder throughput.

Applications

  • Blown & Cast Film
  • Extruded Foam
  • BOPP, BOPET
  • Sheet extrusion
  • Profile Extrusion
  • Polymer- PE, PP, PS & PET

Antislip

PTMB anti-slip masterbatches are based on an organic and inorganic chemical with non-migrating property which gives no adverse effect in machine or final products. It is recommended to give a sandpaper like surface effect for the modification of thick films (>80 to 100 microns). It has property to give rough surface without affecting the machine screw and barrel as there is no abrasive material used.

Key benefits

  • Very good anti slip property
  • Prevent from slippage
  • Creates natural rough surface of film and sheet.
  • Increase COF
  • No adverse effect on screw wear

Applications

  • Heavy duty plastics bags
  • FFS Bags

Antiblock

PTMB have developed a range of anti-blocking additives masterbatches which modify the surface characteristic by creating a micro-rough surfaces or smoother surface, thus reducing the coefficient of friction. This helps to prevent self-adhesion of plastic film or sheet, making it easier to handle.

Key benefits

  • Reduces friction between films layer
  • Reduces adhesion of plastic products
  • Eliminate film & sheet blockage.
  • Easy de-nesting of thermoformed cups.
  • Easy roll unwinding and machinability.
  • No effect on product color and transparency.

Applications

  • Shopping bags
  • Thermoforming cups
  • Glasses trays.
  • PET sheets
  • BOPP film
  • PC & PMMA Sheet
  • Cap & closers

Antistatic

PTMB Antistatic Masterbatches are used in order to reduce static charge buildup and lowering the surface resistivity of plastics products during processing and uses. It modifies the resistivity levels of plastics to values below 1010 ohms.sq. which allows any charge decay to the earth.

Key benefits

  • Reduces dust pickup & static charge build-up.
  • Protects sensitivity electronic packaging and cards & good efficiency at low humidity.
  • Reduce surface resistivity 10E10 – 10E12 Ohms. Sq.
  • Reducing the risk of a potential fire hazard in production environments.
  • Secures optimum transparency in clear plastic containers.
  • Handling problems during transport, storage and packing.

Applications

  • Food packaging
  • Cosmetic packaging
  • Electronic packaging
  • Automotive interior

Antifog

Anti-fog additive masterbatches are added to polyolefin films to reduce their surface tension thereby preventing the formation of water droplets on the film surface for maintaining the film transparency which is needed in hot or cold food, fruits or vegetable packaging.

PTMB anti-fog additives masterbatches eliminates this problem by lowering the surface tension of water droplets causing this hence maintaining the clarity of the film.

Key benefits

  • Creating a food packaging container with a cloud free appearance.
  • It maintains optimum transparency by lowering the surface tension on the film.
  • In high humidity condition it also show excellent effect.
  • Food contact compliance
  • Improve crops and plant growth
  • Keep the film is clear even at cold or hot climate

Applications

  • Food & vegetable packaging film
  • Meat packaging films
  • Thermoforming food packaging
  • Greenhouse films
  • Tunnel Films
  • Horticulture films
  • Face shield

Antitack

PTMB Anti-tack additives are commonly employed in the plastics industry in order to prevent adhesion of plastic objects to themselves, to each other and/ or to other objects.

Key benefits

  • Improves anti-tack property
  • Reduce plastics to plastics adhesion
  • Reduce product damaging and improve life
  • Easy to handle
  • Less energy required
  • Good antilocking property
  • Reduce friction
  • Increase line speed

Applications

  • Shrink film
  • Stretch wrap
  • Stretch hoods
  • Heat shrink wrap
  • LD, LLD, HDPE, EVA
  • LDR 2-3%

Antiscratch

PTMB anti-scratch additives improve the scratch and mar resistance in PP., TPO and other polymers. It can impart scratch and mar resistance up to 10-15 newtons with 5-finger and the cross Erichsen tests which is used by most of automotive producers.

Key benefits

  • Reduction of scratch width
  • Reduce scratch whitening
  • Improves surface smoothness
  • Improve mechanical properties
  • Improve processing performance with less torque
  • Lowering coefficient of friction (COF) and improve gloss
  • Improve mold releasing and oxidative stability

Applications

  • Automotive interior and exterior parts
  • Home appliances
  • Electronics cover and parts
  • Toilet sheets and cover
  • Garden furniture

Matte Effect Masterbatch

Matte Effect Masterbatches from PTMB are added to polymers to modify surface properties to reduce gloss and develop a matte or paper effect in PE, PP, PET film and sheet product application.

Key benefits

  • Excellent compatibility in various resin.
  • Reduces gloss and maintain physical properties.
  • Give matte or paper effect.
  • Impart whiteness and opacity to plastic products.
  • Enhancing appearance by light diffusion.
  • Good anti-blocking property.

Applications

  • Matte finish and/or to lower the gloss of a plastic parts or film.
  • Automotive interior and exterior parts.
  • Home appliances.
  • Doors & Window.
  • Garden Furniture.
  • PET Bottles to give opaque and reduce glare.
