Antifog Masterbatch

By


Product Description:

Antifog Masterbatch based in LLDPE, LDPE resin. Active additive contain rapidly migrates to film surface, reducing the contact angle of condensed water droplets, giving anti-fogging effect to finale product, condensation of water vapor is created by a temperature gradient up to and across a film.

The appearance of condensation is also affected by the difference in surface tension between condensed water vapor and the film’s surface. Technofill Additives offering Antifogs MB are use in food packaging to improve the aesthetics by reducing the beaded appearance of fogged sheet or film.

Technofill Additives are use a high performance property and blend of ingredients additives in Antifog MB that migrate to the surface of the film or sheet and reduce the surface tension of the water droplets that may form. Internal additives must maintain a balance of incompatibility that allows them to migrate while not easily washing’ off and out of the polymer matrix. They must also comply with durability criteria that will give them a time period of effectiveness that is suitable to the application.

Polyolefin’s such as PE and PP have a surface that is particularly hydrophobic and the intent of the Antifog is to increase the surface energy. When the surface tension is decreased water beads tend to ‘wet out’ meaning the contact angle is reduced. The reduced contact angle improves transparency and negative aesthetic qualities are reduced.

Antifog MB takes into consideration the film thickness, process conditions, service conditions, processing methods, and regulatory requirements when prescribing an Antifog masterbatch.

All of TECHNOFILL masterbatches are pelletized, dry, and free flowing making them suitable for film or sheet packaging in cold and hot food contact applications. They provide excellent clarity and thermal stability at low use levels.

Mode of Action:

Antifog Masterbatch is result of combination of two chemistry, which prevents formation of water droplets
èPrevents water droplet cloudiness meets heat stability, low volatility.
èPrevents vopour (pressure of water) formation during film production without yellowing effect and any
     negative influence over transparency & odor of the films

Benefits of Antifog  Masterbatch:
èIts allows perfect transparency of food packaging.
èIts improves visual attractiveness of content.
èFood quality does not deteriorate for longer time.
èUseful in eliminating Hot and Cold fog formation.
èFDA approved. • Improves the light transmission in agriculture film resulting in higher plant growth.
èReduces the burning of plants and crop spoilage.
èTrue universal compatibility in LDPE, LLDPEPP, PVC, PVDC, and  EVA films.

Product Description: Polyisobutylene Additive (PIB Masterbatch) i s a based on a special blend of Polyisobutylene with base polyethylene, elastomeric olefins and active additives. The composition is used as a adhesion promoter (cling agent) to produce stretch wrap films from LLDPE or LDPE, the high molecular weight Polyisobutylene content in the base polyethylene and matrix achieves the excellent stickiness property in the dry granules, it is dry free flow granules Polyisobutylene Additive (PIB Masterbatch) is available in the granule form which is very easy to handle as against the direct dosing of Polyisobutylene liquid which is very difficult & tedious to handle due to high viscosity. Our Polyisobutylene Additive distributes very uniformly over the entire film imparting the strength & tackiness properties to the film with self adhesive properties. And this property of the film helps to wrap the packages together with proper grip. Polyisobut...

Product Description: PPA Masterbatch can be used to improve the processing performance of all types of polyolefins, including  LLDPE, LDPE, HDPE and PP by extrusion process. Polymers melt fracture is generally the surface imperfection seen as a regular surface with ridges running perpendicular to the extrusion direction especially in films, which is also known as “Shark Skin Effect” Recommendations for masterbatch Preparation should not have PPA content above 5% since this can lead to poor dispersion. A level around 2% is desirable. The table below can be used to determine the percentage of masteratch to be included in the final mixture to obtain the required level in PPM Addition Rate – PPM Level PPA9005 PPA9004 PPA9003 PPA9002 PPM Level Dosing   0.5% Dosing   0.6% Dosing   0.7% Dosing   0.8% 250 ...

UV ADDITIVES MASTERBATCH

By

Product Description: TACHNOFILL ADDITIVES has developed a complete range of UV Additive Masterbatches, with selected heat and light stabilizers, for every polyolefin application, all Polymers products exposed to heat, light and oxygen, are subjected to degradation, the degradation process can be retarded and the useful life of plastic products prolonged,  by the addition of stabilizers in the polymer, the most important reason causing degradation of plastics is the Ultra Violate radiation of the sun. the energy carried by this radiation initiates or accelerates chemical reactions chain in the polymer's molecules, causing chain - scission and cross - linking. as a result, the plastic product is loosing its properties and becomes brittle. Special Features: è The careful selection and balanced formulation of different additives. è The excellent dispersion of the additives in the base resin. è Easy processing without affecting the me...
