Q

PBAT blocking and poor opening property

A

Poor opening property of PBAT is a common problem of biodegradable films; anti-blocking agent and tension control work together; zinc stearate has both slip and anti-blocking functions.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent rec...

Extrusion & Post PBAT; blocking; opening property; anti-blocking agent; tension; winding

Q

PBAT Too Soft, Conveying Difficult

A

PBAT's flexibility is a film-forming advantage and a processing disadvantage; filler modification is the main means to increase rigidity; the 15% filler upper limit is the balance point of performance and cost.

Q

PBAT Low Melt Strength, Unstable Blown Film

A

PBAT's low melt strength is the core bottleneck of the film blowing process; chain extender modification is the standard countermeasure; melt index 15g/10min is the flowability upper limit for the blowing process.

Extrusion & Post PBAT; melt strength; film blowing; hole breaking; chain extender; bubble
