PBAT TH801T TUNHE biodegradable plastic film blow grade

Tunhe’s PBAT TH801T is completely compostable according to various international standards and regulations like European standard EN 13432 and American Standard ASTM 6400, which will be eventually biodegraded to carbon dioxide, water and biomass when metabolized in the soil or compostable under standard conditions. Our resins are also certified by Ok Compost, BPI, ABAM, JBPA, FDA, EU Food Contact regulations, etc.

Compared with other biodegradable plastics, PBAT has excellent mechanical performance, almost same as PP and ABS, good heat resistance and outstanding processability allow it to be variously processed on conventional blown film plants, it is the best biodegradable plastic in terms of processability in current market and can be blended with a great quantity of calcium carbonate and starch etc. to produce cost effective products.

Ø         Processing guide

It is recommended to pre-dry the material prior to getting the best processing performance. If the moisture of the resin is less than 0,3% pre-drying may not be needed. Typical drying condition is 2 hours at 80 °C.

The material can be extruded on common extruders. The extruder should be cleaned properly, noting that optimal extrusion temperatures are relatively low, preferably 140 - 160 °C. To obtain lower melt viscosities, temperatures can be increased to a maximum of 210 °C.

For film blowing it is recommended to add slip additives like SiO2 or CaCO3. It is important to start the process from the lowest temperature and increase the temperatures by 5 °C to further optimization of the blowing performance.

TH801T can also be blended with starch, PLA, PBS, PHA, cellulous materials, natural powders, fibers, etc.
