Our Colormate® color Masterbatch and preparation can be customized to incorporate pigments with low migration properties.
Just tell us what resin and the intended application of your product, so we can formulate the best plastic colours without worrying about migration problems.
We offer customization with our Colormate® Color Masterbatches and Preparations. We have a wide range of pigments selections which we can combine and match your choice of plastic colours dedicated to suit either long term application (high light fastness) or outdoor applications (wethering conditions).
Definitely. Plastic products in contact with food or simply “”food contact materials”” have one of the stringiest regulations in plastics. These regulations may vary according to your location or market area. Example., there is US FDA 21 CFR, EU 10/2011, PNS 1104, and many more.
Our Colormate® color Masterbatches and preparation are customizable to have pigments suitable and compliant for these multiple food contact material regulations. Just give us your current market areas and target market areas, and we will use the right kind of pigment for your products.
Gels are common for any polyolefins as it form during the high-temperature extrusion process due to the degradation of the resin material. Polygard® AO masterbatch are anti-oxidant blend to prevent and retard this degradation process reducing gel formation and eventualty preventing burnt particles.
Die lines are usually due to either melt fracture, clogged die, or jagged dies. For melt fracture, and minor jagged dies, our Flo-aid® Processing aid can effectively reduce this problem at a low let-down ratio (1%).
For clogged dies, Hi-Purge® purging compounds can efficiently clean and remove burnt particles, contaminations, and other stuck materials in your die. You can follow this with Flo-aid® Processing aid to reduce the instances of further degradation and gel formation.
Die lines are usually due to either melt fracture, clogged die, or jagged dies.
For melt fracture, our Flo-aid® Processing aid can effectively reduce this problem at a low let-down ratio (1%). This reduces build-ups which cause die lines.
For clogged dies, Hi-Purge® purging compounds can efficiently clean and remove burnt particles, contaminations, and other stuck materials in your die. You can follow this with Flo-aid® Processing aid to reduce the instances of further degradation and gel formation.
For minor jagged dies, our Flo-aid® Processing aid can effectively reduce this problem at a low let-down ratio (1%). This processing aid can effectively coat small die imperfections which can impart die lines.
For major jagged dies, polishing and coating will be the solution to resolve die lines.
For formulation issue, high filler loading or wrong ratio of low MI to high MI resin formulations can result to die lines. Adjusting formulation can resolve this issue.
Gels are common for any polyolefin films as they form during the high-temperature extrusion process due to the degradation of the resin material or from contaminations.
For burnt and degraded resins,
These can be easily solved by adding stabilizers. Polygard® AO masterbatch is an anti-oxidant blend to prevent and retard this degradation process reducing gel formation and eventually preventing burnt particles.
To have better processing, Flo-aid® Processing Aid can also reduce prolonged molten resin adhesion which results in gels and eventually burnt particles.
For contamination, Fish eyes can indicate moisture or volatiles, this can easily be solved by drying your resins.
long fibers can indicate contamination from sack packaging, threads, clothing, or even wood materials. This can be solved by replacing your screenpack with a new one.
Big circular gels can indicate wrong resins, This can be solved by replacing your screenpack with a new one.
Still, the best solution is proper storage and handling to avoid contaminations.
Improper winding tension can be attributed to many factors:
- slow take-up. This can be solved by either adjusting the winding speed slower or the take-up unit faster.
- Friction with the rollers. This can be resolved by replacing busted or rough rollers.
- Soft materials. If your are using LDPE or LLDPE, this can be solved by adding Polymate® Slip Agent. Just make sure you will add the right dosage depending on your resins’ specification.

Our Chemstat® Anti-static are formulated to functionalize plastic to be static dissipative. These can be used with letdown ratios of 1 to 5% depending on the application.
We have two kinds of migratory anti-static, for general applications and for food contact/electronic applications.
general-purpose Chemstat® can be used for dust management, secondary packaging, and static control.
Food Contact/Electronic grade Chemstat® is designed for food packaging and primary electronic packaging.
