Product introduction:
The d501/d502 series of biodegradable materials produced by PBAT+PLA+ starch are applicable to the biodegradable modified materials formed by film blowing. They do not contain pe/pp and other polyolefin materials. They can be processed by traditional film blowing equipment and degraded in 180 days under composting conditions. They can be biodegradable into water, carbon dioxide and non-toxic minerals, and have no pollution to the environment.
Through film blowing machine, tape casting machine, bag making machine, printing machine and sealing machine to produce the required packaging products. The traditional LDPE die head with screw length diameter ratio l/d ≥ 30:1 and film blowing expansion ratio (die mouth / film bubble) 1:3 is selected, which is conducive to plasticizing and improving product quality. Film blowing temperature 140 ℃ -155 ℃.
