SpletThe Hanatek Film Shrink Tester (FST) has been designed to quickly and easily measure the. effect of temperature on plastic film. The application of heat causes certain plastic films to rapidly contract; this effect can be used to seal and pack many items from food to consumer goods. The shrink effect is due to internal forces locked into the ... Spletmers in the mature compost soil and found that the biodegradability of PBS was slower than that of PBSA in compost soil [68]. However, the results of enzymatic hydrolysis as well as environmental degradation of PBS are highly dependent on the environment, the composition of the PBS grade, and its compound[55]. 1.3.5 Bio-basedPolyethylene
